Side Reactions/Changes in Lithium‐Ion Batteries: Mechanisms and Strategies for Creating Safer and Better Batteries

Advanced Materials, Volume 36, Issue 29, July 18, 2024.
Lithium‐ion batteries are considered the most competitive energy storage devices. A deep understanding of the reactions that cause changes in the battery's internal components is needed to build safer and better batteries. This review focuses on the processes of battery failures, with voltage and temperature as the underlying factors.

Multilevel carbon architecture of subnanoscopic silicon for fast‐charging high‐energy‐density lithium‐ion batteries

Carbon Energy, Volume 6, Issue 4, April 2024.
The C/VGSs@Si–C composite is fabricated by using a multilevel carbon architecture strategy on subnanoscopic Si. The strategy involves a highly developed three‐dimensional conductive and robust network integrating a subnanoscopic C skeleton, VGSs, and a carbon matrix, which enables the use of subnanoscale Si as a high‐energy‐density and fast‐charging ...
