Description

Opportunity:

Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its protective film for current collectors and lithium metal for battery applications.



Background:

Commercial lithium-ion (Li-ion) batteries based on graphite anodes are meeting their energy density limits. In order to satisfy the large market demands of smaller and lighter rechargeable batteries, high-capacity Li metal has been suggested as a replacement for low-specific-capacity graphite enabling higher energy density next-generation rechargeable Li metal batteries (LMBs), or all solid-state batteries (ASSBs) with Li metal as the anode to be realized. However, Li metal anodes suffer from dendritic problems, interfacial side reactions with liquid or solid electrolytes, significant cell volume change during battery cycling, and low Coulombic efficiency when used as an anode in different cell configurations. In order to overcome the above challenges, the main direction is to achieve a uniform Li deposition during Li plating and stripping, protecting lithium metal from Li dendrite formation. The construction of artificial protective layers before assembling cells has been shown to be very effective for LIBs and ASSBs. This idea could also be applied to Li metal batteries.



Description:

LLNL researchers have developed an artificial protective layer fabricated through a scalable and low-cost process, that can serve as a protective layer for improving the performance of any battery configuration using Li metal as an anode as well as the performance of anode-free Li-metal batteries or anode-free SSBs. This film can suppress Li-dendrite formation because of its mechanical properties. The invention helps solve a key cha...
