Abstract

A F-deficient and high-Mn ternary perovskite fluoride anode (K_1.00Ni_0.06Co_0.14Mn_0.80F_2.92, KNCMF-3#) has been explored for advanced Li-ion batteries (LIBs), showing a dominant conversion mechanism. Notably, the KNCMF-3#//LiFePO₄ (LFP) LIBs furnish an ultra-high performance of 270.5–35.9 W h kg⁻¹/0.63–11.6 kW kg⁻¹/71% retention/5000 cycles/5 A g⁻¹.
