By introducing Li insufficiency, we found that m-LiBC exhibits a higher capacity compared to original o-LiBC, thanks to the structural evolution and interlayer rearrangement. This understanding may open a new avenue for activating Li+ extraction in other lithium compounds.
By introducing Li insufficiency, we interestingly found that m-LiBC exhibits a higher capacity (220 mA h g(-1)) than the original o-LiBC (50 mA h g(-1)). This improved capacity benefits from its structural evolution, with the interlayer rearrangement changed from ABABAB (o-LiBC) to ABAABA (m-LiBC) stacking, triggered by Li insufficiency. This understanding of interlayer rearrangement for LiBC may open a new avenue to activate Li+ extraction in other lithium compounds.
