Abstract:
A lithium ion battery is provided, which includes a positive electrode, a negative electrode, and an electrolyte disposed between the positive electrode and the negative electrode. The negative electrode includes a current collector and a β-phase-based polyvinylidene fluoride (β-PVDF) layer coating on the current collector. The β-PVDF layer may have a thickness of 1 μm to 10 μm.
