Solidifying High-Concentration Electrolytes Using Faujasite as Nanosized Porous Zeolite Additive for Solid-Type Batteries

High LiTN quasi-solid electrolyte Discharge ChargeA hybrid electrolyte composed of a high-concentration electrolyte made of dimethyl carbonate and lithium bis(fluorosulfonyl)imide and lithium exchanged faujasite-type zeolite exhibits solidification of the electrolyte with high ionic conductivity and excellent contact properties with a lithium metal anode and an olivine-type LiFePO 4 cathode.The assembled battery showed excellent cyclability for at least 100 cycles at a charge rate of 1 C at 60 C with a discharge capacity retention of 98.6 % and high coulombic efficiency.
