Hybridizing anions towards fast diffusion kinetics for tri-ion batteries with significantly improved rate capability and cycling life

We develop a new aluminum graphite tri-ion (Li⁺/PF₆⁻/BF₄⁻) battery configuration (AGTIB) using an anion-hybridization strategy with fast diffusion kinetics. The AGTIB has a high rate performance with a 90.5 mA h g⁻¹ capacity at 15C and good cycling stability for over 500 cycles at 5C.
