Abstract

Separator is an essential component of battery between anode and cathode, but the commercial micro-porous polyolefin separator can hardly satisfy the continuously increasing battery energy densities due to its poor mechanical stability, low wettability, and limited electrolyte uptake. Poly(vinylidene fluoride -hexafluoropropylene-MnCO3)(PVDF-HFP-MnCO3) separator is synthesized and investigated for lithium-ion batteries. In addition to enhanced battery stability owing to the stable pore structure, the separator has a high electrolyte uptake, which gives them a remarkable rate performance. LiFePO4/Li cell with PVDF-HFP-MnCO3 separator delivers a capacity up to 145 mAh g-1 at 0.5 C, and only 4.7% capacity degradation was observed after 100 charge/discharge cycles.
