Key Points

To investigate the effects of negative-to-positive electrode crossover of soluble species on the degradation of lithium-ion batteries with silicon electrodes.
Examined the performance of silicon-based negative electrodes in lithium-ion batteries.
Monitored changes in electrode materials under charging conditions.
Assessed the degradation patterns in relation to crossover events.
Silicon electrodes exhibited significant capacity reduction over time due to crossover events.
Degradation was accelerated by the presence of soluble species migrating from the negative to positive electrode.
Findings indicate that crossover impacts the overall lifespan and efficiency of lithium-ion batteries.

Implication

Demonstrates accelerated degradation in lithium-ion batteries due to soluble species crossover in silicon electrodes, indicating potential challenges for fast-charging technologies.

Abstract

Si-based negative electrodes are promising alternatives to graphite because of their exceptional theoretical capacity and potential for fast-charging Li-ion batteries (LIBs). However, the large volume changes of Si and the...
