Summary: In this study, the conversion properties of Cu(PO3)(2) as a cathode material for Li rechargeable batteries were enhanced through amorpholization and carbon-mixing. The amorphorized Cu(PO3)(2)/C composite exhibited higher reversible capacity and average operation voltage compared to crystalline Cu(PO3)(2)/C composites. The excellent power capability and cyclability of the amorphorized Cu(PO3)(2)/C composite were attributed to the enhanced kinetics of the conversion reaction in Cu(PO3)(2). The reversible conversion-reaction mechanism of Cu(PO3)(2) in a Li-cell system was also demonstrated through various experimental measurements.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.
