Long cycle life and dendrite-free lithium morphology in anode-free lithium pouch cells enabled by a dual-salt liquid electrolyte | Cornell Energy Systems Institute

Schematic of the fully charged anode-free configuration with about 40% reduced thickness compared with an equivalent lithium-ion cell. b, Capacity retention versus cycle number for anode-free pouch cells using electrolytes with different lithium salts. c,d, Capacity retention versus cycle number as a function of upper cut-off voltage for two electrolytes with different salts: 1.2 M LiDFOB (c) versus 0.6 M LiDFOB + 0.6 M LiBF4 (d). All electrolytes use an FEC:DEC (1:2 vol.) solvent mix. Pairs of cells for
