Research on lithium-air batteries has progressed

Researchers from the Chunying Institute of Chemistry, President of the Chinese Academy of Sciences, have made a series of progress in lithium-air battery research, and for the first time designed and developed lithium-air secondary battery battery packs
that can be applied in practical applications and have independent intellectual property rights.

According to reports, by inhibiting the decomposition of the electrolyte of lithium-air batteries, the researchers have greatly increased the cycle life of lithium-air batteries from the maximum 100 times reported in the current literature to 500 times; For the first time, sulfoxide (DMSO) and sulfone (TMS) were applied to lithium-air secondary batteries, which effectively promoted the formation of reversible discharge product lithium peroxide) and reduced side reactions
.
In addition, the team also proposed the concept of graphene integrated air electrode for the first time, and successfully constructed three-dimensional porous graphene in the nickel foam matrix, so that the prepared lithium-air battery showed excellent rate performance
