Functional separators for batteries

Batteries electricity storage is a rapidly expanding industrial sector, thanks to the bloom of portable electronic, electrified transport, and stationary storage. Lithium-ion technology has allowed considerable progress in performance, but challlenges still need to be addressed to improve energy density, power and life cycle in batteries.

The technology proposed herein is focused on the battery separators. With a simple modification of commercial separators, lifetime and performances of batteries integrating those new membrane separators are greatly improved.
