Performance comparison of polymer and ternary lithium batteries
Polymer lithium battery: more flexible design, higher mass specific energy, wider electrochemical stability window, higher safety and reliability, longer cycle life, slower capacity decay rate, higher volume utilization rate, lower internal resistance, Lighter weight and less self-discharge.
Ternary lithium battery: In terms of safety, its safety is higher than that of lithium cobalt oxide battery, but lower than that of lithium iron phosphate battery. The safety of all current commercial lithium-ion batteries is at a medium level and needs to be improved; energy density On the voltage platform, its monomer has an absolute advantage, which is 3.7V, while lithium iron phosphate is 3.2V, and lithium titanate is 2.3V.
