3DOM will Start Mass Production of Lithium Ion Battery with Improved Energy Density and Reliability From 2021 and Expand into Overseas Industrial Applications Markets

3DOM Inc. (Yokohama City, CEO: Masataka Matsumura), an entrepreneurial venture company originated from Tokyo Metropolitan University, has successfully developed a lithium ion battery that has enhanced both energy density and reliability.

Application of lithium ion battery is expanding all around the world, particularly to electric vehicles (EVs), small consumer applications such as smart phones and drones, and stationary energy storage systems that are installed in houses with solar panels.

Lithium ion battery, however, uses many combustibles as materials for electrolytes and other components. The lithium-nickel-cobalt composite oxide used as the cathode material can be locally short-circuited depending on the usage such as repeated rapid charging and discharging. When Joule heat is generated because of such reasons, there is a possibility that the cathode material is thermally decomposed, thereby releasing oxygen, and at the same time, the electrolytic solution is burned to cause ignition. If another cathode material such as a lithium composite oxide having higher heat resistance is used, there is an issue of reduced energy density. Under the situation that batteries with higher energy density are required, how to improve reliability without lowering energy density has been a challenge.

This time, 3DOM has paved a way to maintain and improve the energy density of the battery through the application of 3DOM’s unique material mixing technology while improving the reliability of the battery by application of highly heat resistant material as a portion of cathode materials. Further, this particular heat resistant material is composed without the use of rare earth cobalt. As it has become possible to reduce the portion of cobalt in the entire cathode materials of the battery, this technology will lead to avoid future fluctuation in market prices of cobalt and to counteract its resource shortage.

The new lithium ion battery cell that is successfully developed this time is housed in a pouch and is in a 30 Ah class. 3DOM has started supplying samples to several companies mainly in Southeast Asia by utilizing 3DOM’s own network and Singapore subsidiary. Further, 3DOM is studying the application of the battery cells to the products of LAVLE, which is 3DOM’s US affiliate that engages in the electric vessels business. Currently, in cooperation with battery manufacturers in the alliance, 3DOM plans to use some portions of the existing factories for mass production and sales of the battery cells from 2021.
In the future, 3DOM aspires to further improve energy density while improving reliability of batteries by using higher energy density materials and applying 3DOM’s proprietary separator technology that realized a uniform three-dimensional multi-porous structure.

3DOM will Start Supplying Samples of 400Wh/kg Class Lithium Metal Secondary Battery for Evaluation by Unmanned Aerial Vehicles (UAVs) from July 2020

3DOM Inc. (Yokohama City, CEO: Masataka Matsumura), an entrepreneurial venture company originated from Tokyo Metropolitan University, has successfully developed a lithium metal secondary battery that has 400Wh/kg weight energy density.

Application of lithium ion battery is expanding all around the world, particularly to electric vehicles (EVs), small consumer applications such as smart phones and unmanned aerial vehicles (UAVs) including drones, stationary energy storage systems that are installed in houses with solar panels, etc. For UAV application, in particular, it is required to reduce the weight of the battery, the power source, as such technology greatly affects the flight time.

Although carbon materials are used for the anode of lithium ion batteries, research and development of silicon alloy anode and lithium metal anode are now underway in various fields in order to further improve the energy density. However, until now, no sufficient performance of long life has been obtained.

In line with the research and development of the proprietary 3DOM separator that have been continuing since the Company establishment in 2014, the Company has continued to undergo vigorous research and development of lithium metal anode battery. This time, 3DOM has paved a way to maintain and improve the energy density of the battery that just meets the requirements of the customers, achieving both the weight energy density and life span performance.

The new lithium metal secondary battery successfully developed this time has twice the weight energy density of the conventional lithium ion secondary battery. The performance evaluation test has started as a secondary battery for UAV, and it is being planned to install the battery on the actual UAV two years later at the earliest.

In the future, by applying 3DOM’s proprietary separator technology and using materials with higher energy density, the Company aspires to further improve energy density while improving reliability. 3DOM plans to enter into various markets including the UAV application market which is expected to grow and weight reduction is particularly required.

LAVLE Has Developed a New Energy Storage System “Proteus”
– Significantly Improved Reliability toward the Spread of Electric Propulsion of Vessels and Other Mobility –


LAVLE USA, Inc. (LAVLE), a U.S. corporation under the umbrella of 3DOM Inc. (Yokohama City, CEO: Masataka Matsumura) that is an entrepreneurial venture company originated from Tokyo Metropolitan University, has announced the flagship model of lithium-ion battery energy storage system (ESS) “Proteus”. Proteus has realized significant improvements in reliability, quality, and cost efficiency with the electrification of marine, defense, energy, railway and other fields in mind.

This ESS is designed to maximize the reliability, lifespan, and uptime of the separators with a homogeneous multi-porous structure, which is the patented technology of 3DOM and the next-generation battery cells utilizing the separators. The performance and high reliability of the ESS are truly epoch-making.

Nearly 95% of the world’s transportation energy comes from petroleum-based fuels, accounting for more than 15% of all greenhouse gas emissions. Early electrification is required to reduce environmental load, and Proteus meets this expectation by improving reliability as shown hereunder.

“LAVLE’s Proteus is the superior solution for delivering the performance and assurance required to further advance electrification in marine transportation and other means of mobility,” said Dr. Jason Nye, CEO, LAVLE. “This is just our first step in bringing innovative, next generation technologies to market that will have a meaningful impact for carbon reduction.”

Proteus is currently undergoing product certification by DNV-GL, the world’s leading classification society.
