Mechanistic insights into capacity discrepancies of conversion-type transition-metal compounds in wide-temperature-range lithium-ion batteries Conversion-type transition-metal compounds (C-TMCs) are widely used as lithium-ion-battery (LIB) anodes due to their high theoretical capacity. However, their significant discrepancy in lithium storage capacity is observed across a wide temperature range, a comprehensive understanding of the underlying mechanism remains exclusive.

1 Introduction The development of high-energy-density lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), and potassium-ion batteries (PIBs) is highly dependent on the capacity of anode materials, in which a higher anode capacity can lead to a higher energy density.[1-5] However, the reversible capacities of the dominated commercial graphite and hard/soft carbon anode materials are low in Li/Na/K storage, basically ranging from 200–360 mAh g−1, which restricts the further enhancement...
