High-Energy and High-Power Primary Li-CFx Batteries Enabled by the Combined Effects of the Binder and the Electrolyte

Several effective methods have been developed recently to demonstrate simultaneous high energy and power density in Lithium - carbon fluoride (Li-CFx) batteries. These can achieve as a 1000 Wh/kg at 60–70 kW/kg (40–50 C rate) coin cells 750 12.5 (20 pouch cells. This performance is made possible by an ingenious nano-architecture design, controlled porosity, boron doping, electrolyte additives. In the present study, we show that similarly great performance, 931 59 density, be achieved using polyacrylonitrile binder LiBF4 Li-graphite We also observed effect result of right combination electrolyte. propose mechanistic origin phenomena electro-catalytic binder. While our proposed method has competitive it offers simple implementation scalable production high-energy high-power primary Li-CFx
