The demand for high capacity and high energy density lithium-ion batteries (LIBs) has drastically increased nowadays. One way of meeting that rising demand is to design LIBs with thicker electrodes. Increasing electrode thickness can enhance the energy density of LIBs at the cell level by reducing the ratio of inactive materials in the cell.
The industry standard defines the consistency of lithium-ion batteries as the consistency characteristics of the cell performance of battery modules and assemblies.
The large-scale battery system leads to prominent inconsistency issues. This work systematically reviewed the causes, hazards, evaluation methods and improvement measures of lithium-ion battery inconsistency. From material to manufacture and usage, the process and conditions of each link affect battery consistency.
The lithium-ion battery is a thermal and electrical coupling system. The temperature has a significant impact on its electrical performance . Effective temperature management can improve the consistency of electrical and thermal behaviors of the battery pack . The battery will generate a lot of heat in the work.
Jiyoung Lee, Seung Hyun Jeong, and Jong Seok Nam contributed equally to this work. The lithium metal battery (LMB) is a promising energy storage platform with a distinctively high energy density in theory, outperforming even those of conventional Li-ion batteries.
Thick Li metal can result in poor performance for large-format cells due to increased weight and volume, as well as vigorous interfacial reactions during cycling. As such, the next generation of LMBs must have lithium metal electrodes that are thinner, lighter, wider, and more stable.
