Which materials are used in battery separators?
Many materials, including polymers, ceramic materials, and nanocarbons, have found applications in both Li-ion and Li-S battery separators. Specifically, polymers are dominating battery separators. The polymers with high melting points and dense polar functional groups tolerate high temperature and render high electrolyte uptake.
Why do li-s batteries need a separator?
However, Li-S batteries exhibit limited energy density and lifespan in their practical applications, mainly due to the shuttle effect of soluble polysulfides. Separator is an essential component ensuring battery performance and safety.
Are polyolefin separators suitable for Li-ion batteries?
Conventional Li-ion battery separators, mainly polypropylene (PP) and polyethylene (PE) membranes, are difficult to satisfy the needs of future EVs' Li-ion batteries. Specifically, the poor electrolyte wettability of polyolefin separators restrained the practical specific capacity and energy density of Li-ion batteries.
How can a battery separator be improved?
The safety issue, which is a major concern that limits battery applications, could be mitigated by increasing the separator's mechanical strength, thermal stability, and shutting the batteries down below thermal runaway temperature through various functionalization approaches.
