UIC-2019-033 – A Novel Graphene Oxide (GO) Separator to increase safety and performance of Li-metal Batteries

Lithium metal batteries are the go-to word in the world of sustainability and renewable energy ever since it gained popularity in consumer electronics and HEVs. Lithium is considered as the ideal anode material for high energy density batteries. One of the key issues with lithium anodes is the dendrite formation which eventually leads to shorting of the battery, leading to Li battery fires. UIC researchers have developed a safe, scalable graphene oxide (GO) layer on a glass fiber separator for Li-metal batteries. These thin GO layers have sufficient mechanical strength to alter the vertical growth of dendrites to lateral growth with promotes more dense deposition of lithium.
