文摘

Lithium-ion dry polymer battery with 4 V cathode and graphite anode is proposed. Addition of LiBOB at cathode/SPE interface is effective for the reversibility. Surface modification of graphite plays a role to minimize the lithium consumption. Proposed battery reached 5400 cycles with 60% capacity retention at 323 K.
