TOKYO, April 18, 2023 – 3DOM Alliance Inc. (“3DOM Alliance”) today announced the development of a lithium-ion battery with the company’s proprietary X-SEPA™ separator and high temperature-resistant electrolyte optimized for use in high temperature environments. Data from charge-discharge cycle life testing shows that battery lifespan under high temperature conditions exceeds that of conventional batteries under normal temperature conditions. 3DOM Alliance expects the lifespan to reach approximately 9,000 cycles.
Developed by 3DOM Alliance, the X-SEPA™ is comprised of multiple layers of 3DOM (3-dimensionally ordered macroporous) separators, which are highly heat-resistant polyimide membranes that contain a uniform three-dimensional array of pores. This contributes to longer battery lifespan as well as improved reliability, heat resistance, and high-rate charge and discharge. Preparing for mass production, 3DOM Alliance began providing X-SEPA™ samples in February 2023.

The global decarbonization movement has brought forward the growing need for electric mobility solutions, especially in developing nations – many of which count amongst the hotter regions of the world. However, high temperatures cause the degradation of general-purpose electrolyte, which significantly shortens battery lifespan. This hinders the practicality of battery electrification and contributes to increased manufacturing, waste, and costs.

Responding to market needs in high-temperature regions, 3DOM Alliance has developed a lithium-ion battery with extended lifespan under high temperature conditions by using the X-SEPA™ in combination with a high temperature-resistant electrolyte. The high temperature-resistant electrolyte suppresses degradation in high temperature environments based on its high viscosity and high boiling point, but it has been difficult to use in lithium-ion batteries because its high viscosity makes it incompatible with general-purpose polypropylene separators. In contrast, the highly porous structure of the X-SEPA™ and the high wettability of its polyimide material to organic electrolytes enable the use of electrolytes with high viscosity and high boiling points.

3DOM Alliance conducted charge-discharge cycle life testing at 60℃ to evaluate the lifespan and durability of batteries equipped with the X-SEPA™ and high temperature-resistant electrolyte in comparison with batteries using a general-purpose separator and electrolyte. As shown in Figure 1, interim results of ongoing testing show that the battery equipped with the X-SEPA™ and high temperature-resistant electrolyte demonstrates significantly higher capacity retention. Even under high temperature conditions, the charge-discharge cycle life of this battery exceeds the charge-discharge cycle life of conventional batteries in a normal temperature environment.

As shown in Figure 2, 3DOM Alliance estimates that the battery equipped with the X-SEPA™ and high temperature-resistant electrolyte may achieve a charge-discharge cycle life of approximately 9,000 cycles when end-of-life is set at 60% capacity retention. 3DOM Alliance plans to verify this through continued testing and announce further results as they become available.

3DOM Alliance’s subsidiary noco-noco Pte. Ltd. (“noco-noco”), a Singapore-based decarbonization solution provider, plans to provide batteries equipped with the X-SEPA^TM through services that leverage resulting battery characteristics, including long lifespan under high temperature conditions. Currently, noco-noco is working to introduce 3DOM Alliance’s battery technology in mobility applications through multiple projects in Southeast Asia, including an electric minibus project with Assemblepoint Co., Ltd. announced earlier this month. Utilizing the X-SEPA^TM, noco-noco aims to address the need for batteries that can achieve higher performance and sustainability in hot climates in order to accelerate electrification in target markets such as South and Southeast Asia.

TOKYO, April 6, 2023 – At the 90th Annual Meeting of the Electrochemical Society of Japan (the “Annual Meeting”) held on March 27-29, 3DOM Alliance Inc. (“3DOM Alliance”) presented the results of two studies related to the charge-discharge cycle life of lithium-ion batteries and next-generation rechargeable lithium metal batteries equipped with the company’s “X-SEPA™” separator.

The X-SEPA™ was developed by 3DOM Alliance over eight years of development. Comprised of multiple layers of 3DOM (3-dimensionally ordered macroporous) separators and highly heat-resistant polyimide membranes containing a uniform three-dimensional array of pores, it contributes to longer battery lifespan as well as improved battery reliability, heat resistance, and high-rate charge and discharge . Preparing for mass production, 3DOM Alliance began providing X-SEPA™ samples in February 2023.

This comes as the global demand for batteries are seeing a rapid increase brought about by rapid electrification. While a vital alternative to fossil fuels, batteries harbor the potential to cause new environmental harm, including carbon emissions from manufacturing, destructive resource mining, and soil and water contamination from insufficient disposal measures. Extending battery lifespan is an important means to mitigate these environmental challenges.

At the same time, there is demand for rechargeable batteries with higher capacity that exceed the performance of lithium-ion batteries currently available. In principle, rechargeable lithium metal batteries with lithium metal anodes offer high energy density and have thus attracted attention as next-generation batteries. However, reduced battery lifespan and reliability due to the uneven formation of lithium dendrites during charging and discharging poses a major hurdle to their practical application.

The research presented at the Annual Meeting provided further scientific support for the charge-discharge cycle life of lithium-ion batteries and lithium metal rechargeable batteries equipped with the X-SEPA™.

① Comparative evaluation of the characteristics of lithium-ion batteries equipped with X-SEPA™ and polyolefin-based general-purpose separators

Summary of report presented at the Annual Meeting: “Characterization of Lithium Ion Battery Using High Porosity Polyimide Separator with Multilayer Structure”
The X-SEPA™ is expected to perform particularly well when used as a separator for lithium-ion batteries at high current density, which requires smooth lithium-ion transport. This is due to the high pore uniformity and permeability provided by its structure. This study verified the comparative effectiveness of batteries equipped with X-SEPA™ and polyolefin-based general-purpose separators.

As shown in Figure 1, the battery equipped with the X-SEPA™ was confirmed to have superior capacity retention from 30 to 200 cycles. The points indicated by arrows in the above figure show the recovery capacity when charged and discharged at 0.2C after 500 cycles. The difference in recovery capacity between the separators suggests that the difference in the retention rate is not due to an increase in resistance but to the difference in the depletion of mobile lithium ions. This suggests that there is a reduced occurrence of lithium deposition in the battery equipped with the X-SEPA™ compared to the polyolefin-based general-purpose separator. These results confirm that the high-porosity polyimide separator is better suited to rapid charging than the polyolefin separator and is effective in extending charge-discharge cycle life performance.

② Improved lifespan and reliability of lithium metal rechargeable batteries equipped with X-SEPA™ and initiatives for large-scale rechargeable batteries

Summary of report presented at the Annual Meeting: “Development of Long Life and Reliable Lithium Metal Batteries Enabled by a High Porosity Polyimide Separator, and Approach to their Higher Capacity”
This research studied the application of a high-porosity polyimide separator in a rechargeable lithium metal battery by examining its effect on charge-discharge cycle and other battery characteristics. Figure 2 shows the charge-discharge cycle characteristics of a rechargeable lithium metal battery equipped with the X-SEPA™, which exhibited a capacity retention rate of 95% even after 200 cycles, indicating lifetime performance with excellent charge-discharge reversibility.

Dr. Kiyoshi Kanamura, Chief Technology Officer (CTO) of 3DOM Alliance and developer of the 3DOM separator, commented, “I am pleased that this research using the X-SEPA™, which consists of multiple layers of 3DOM separators, demonstrates long battery lifespan characteristics and can thus help to improve the environment amid strong demand for long battery lifespan in the movement towards decarbonization.”

3DOM Alliance’s subsidiary noco-noco Pte. Ltd. (“noco-noco”), a Singapore-based decarbonization solution provider, plans to provide services that leverage the superior characteristics of batteries equipped with the X-SEPA™. Extended battery life is expected to bring environmental and economic benefits. This extends to supporting a circular economy that encompasses battery second-life use, thus reducing the total required number of batteries in circulation and in turn decreasing environmental damage from battery manufacturing and disposal. It also works to reduce costs per charge-discharge cycle, thus alleviating financial obstacles to electrification for users.

In the future, the X-SEPA™ holds the potential for use not only in lithium-ion batteries, but also rechargeable lithium metal batteries fit for next-generation applications that require high energy density. By redefining batteries equipped with the X-SEPA™ as a social infrastructure in service offerings, noco-noco endeavors to unlock the full potential of batteries to mitigate urgent environmental issues.

TOKYO, March 23, 2023 – 3DOM Alliance Inc. (“3DOM Alliance”) conducted nail penetration short circuit resistance testing on batteries equipped with the X-SEPA™, a revolutionary separator technology with a multi-layer structure that further enhances durability of the company’s 3DOM (3-dimensionally ordered macroporous) separator. The testing produced favorable results compared to a general-purpose separator.

A nail penetration short circuit test is one method of evaluating reliability in abnormal conditions by driving a metallic nail through a charged lithium-ion battery cell at a prescribed speed to simulate internal short-circuiting. Internal short-circuits are a leading cause of battery ignition and explosion incidents and may result from external impact, manufacturing defects, or metal deposition during charging and discharging.

To evaluate the X-SEPA™’s contribution to cell reliability, nail penetration short circuit tests were conducted on two 3.3Ah lithium-ion battery cells with identical design specifications except for the separator. Testing on the cell with a general-purpose polypropylene separator resulted in thermal runaway and venting, corresponding to EUCAR (European Council for Automotive R&D) Hazard Level 4. Testing on the cell equipped with the X-SEPA™ did not result in thermal runaway and produced no smoke or flame, corresponding to EUCAR Hazard Level 2.

The effect of the X-SEPA™ on the test results was assessed by conducting a puncture test on the separators and a local heating test, in which a soldering iron heated to 450℃ was touched to the separators to reproduce the conditions of local heating generated from internal short-circuiting by the nail. In contrast to the general-purpose product, no aperture was observed in the X-SEPA™ due to the three-dimensional pore structure and heat-resistant material. This supports the favorable results of the nail penetration short circuit test.

3DOM Alliance has made preparations for mass production and began providing samples of the X-SEPA™ to battery manufacturers in February 2023. The company’s subsidiary noco-noco Pte. Ltd. (“noco-noco”), a Singapore-based decarbonization solution provider, plans to provide batteries equipped with the X-SEPA™ through services that leverage resulting battery characteristics such as long lifespan, reliability, heat resistance, and high-rate discharge. Utilizing the X-SEPA™, noco-noco aims to alleviate safety concerns and other hurdles to electrification for mobility operators in order to drive decarbonization in the transport industry.

3DOM Alliance Inc. has increased all employees’ base salaries by 5% beginning in February 2023.

3DOM Alliance believes that employees are at the root of all value creation. The company has therefore continually invested in human capital, including by granting stock options. In response to a recent sharp rise in the prices of daily commodities due in part to the weak yen, 3DOM Alliance has decided to further invest in its employees in order to maintain and improve their quality of life.

3DOM Alliance will continue working to increase its competitiveness in the hiring market and attract top talent to support the company’s endeavor to create new value and truly solve environmental problems.

TOKYO, February 8, 2023 – 3DOM Alliance Inc. (“3DOM Alliance”) announces that samples of the X-SEPA, a revolutionary separator technology, have begun shipping. The X-SEPA, as first announced in December 2022, has a unique structure that helps to improve the performance of existing battery technologies and accelerate the speed of next-generation battery development, thereby promoting the transition to a more sustainable electric society.

Last year, 3DOM Alliance announced that preparations had been made for mass production following eight years of separator research and development. The company has now started providing X-SEPA samples to battery manufacturers around the world. 3DOM Alliance is already working to respond to requests for samples from more than ten companies and preparing to increase X-SEPA production volume by the end of the year.

The X-SEPA is comprised of multiple layers of highly heat-resistant polyimide membranes, within each a uniform three-dimensional array of pores. This unique structure allows for fine control over separator properties in each layer and overall optimization according to the application and desired battery performance. The X-SEPA thus transcends the conventional function of a separator to provide new added-value to batteries. The structure and material provide longer life, higher reliability, and high-rate discharge performance. This offers a solution to several challenges in the battery industry, including the need for adequate safety and technologies suitable for up-and-coming applications such as electric vehicles in high-temperature regions of the world or air mobility. Furthermore, the regularity of the structure allows for flexible design and optimization as well as simulation through high-precision modeling, which has the potential to drastically accelerate the battery development process.

noco-noco Pte. Ltd. (“noco-noco”), 3DOM Alliance’s Singapore-based subsidiary, will buy long-life batteries equipped with the X-SEPA that have been manufactured by strategic allies and utilize those in services spanning battery first- and second-life use. The aim is to address environmental issues by reducing the required number of batteries in circulation by as much as 75% while maximizing the efficiency of their use. noco-noco intends to encourage this shift away from the unsustainable economic system of mass production and mass consumption through an innovative “Data & Profit Sharing” business model, in which companies that help to extend product life can gain access to battery-related information and continually receive a share of profits over the span of the product’s service life.

By reimagining the role of the separator and repositioning batteries as social infrastructure, 3DOM Alliance and noco-noco are working to address shortcomings in today’s battery industry and unlock the full potential of batteries to mitigate urgent environmental issues.
