FIBROID SEPARATOR AND ENERGY STORAGE DEVICE USING THE SAME

摘要

Disclosed are a fibroid separator and an energy storage device using the fibroid separator. The fibroid separator has a fibroid film and a polymer layer having polymer formed on the fibroid film. The fibroid film has many pores, therefore the fibroid separator has a superior electrolyte absorption capacity and electrolyte maintenance characteristics. Also, by using the fibroid separator having adequate quantity of porous, energy storage device such as the lithium polymer secondary battery having good cycle-life characteristics and good adherence characteristics between the separator and the electrode without Li-deposition, can be provided.
