Application Progress of Rare Earth Doping in Solid Electrolyte of Lithium Ion Battery

The development trend of all solid state lithium ion battery and the importance of lithium ion solid electrolyte in all solid state lithium ion batteries is introduced in this paper. The application of rare earth doping in solid electrolyte of lithium ion battery is summarized. We suggest that rare earth doping is favorable for the increase of the lithium ion battery electrolyte conductivity, thus it is beneficial to further improve the overall performance of all solid state lithium ion battery. The development prospect of rare earth doping in solid electrolyte of all solid state lithium ion battery is looked forward. In addition, we deem that the above mentioned technology is an important research aspect of solid state electrolyte.
