Core Technology

3DOM Separator Technology3DOM Separator

Homogeneous three-dimensional pore structure

The homogeneous structure of pores makes the ionic current distribution uniform, suppresses deterioration on account of precipitation of dendrites and uneven reactions of electric power, and improves battery’s reliability and performance.

Homogeneous size and alignment of pores

As a result of realizing extremely uniform pores and their alignment, the flow of ions between the electrodes becomes uniform, and degradation of batteries is suppressed as the dendrite precipitation and non-uniform reactions of electrodes are substantially contained.

High porosity ratio

3DOM separator has the structure of three-dimentionally ordered spherical pores, and possesses high ion conductivity because of maintaining more than 70% of porosity ratio.
