文摘
- •
99% coulomb efficiency at LiNi0.5M1.5O4 cathode with sulfone–carbonate electrolyte.
- •
This electrolyte also yields 97% capacity retention at LiNi0.5M1.5O4 over 100 cycles.
- •
Also reported is ideal capacity retention and efficiency at Li4Ti5O12 anode.
- •
So Li4Ti5O12/(this electrolyte)/LiNi0.5M1.5O4 full cells offer safe, efficient, long life with reduced fire risk.
