"enhance safety, high-voltage stability, and energy density by maintaining good mechanical strength, eliminating interface in polymer, and suppressing Li dendrites... liquid electrolytes' low-contact resistance and solid electrolytes' safety electrolyte blending 2 miscible polymers: Li+ conducting polymer and fluorine-based inert polymer... Li-dendrite suppressor forms SEI layer blocking lithium dendrite and preventing short circuits... inert polymer adds mechanical strength... coulombic efficiency >99%... small smart devices"
