Extending the charging cutoff voltage of lithium cobalt oxide (LCO) cathodes is an effective strategy to enhance the energy density of lithium-ion batteries (LIBs), while the formation of a poor cathode–electrolyte interphase (CEI) has limited their widespread application.
Lithium-ion battery safety is one of the main reasons restricting the development of new energy vehicles and large-scale energy storage applications . In recent years, fires and spontaneous combustion incidents of the lithium-ion battery have occurred frequently, pushing the issue of energy storage risks into the limelight .
The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
The advantages of lithium-ion batteries are very obvious, such as high energy density and efficiency, fast response speed, etc , . With the reduction of manufacturing costs of the lithium-ion batteries, the demand for electrochemical energy storage is increasing , .
Lithium-rich materials (LRMs) are among the most promising cathode materials toward next-generation Li-ion batteries due to their extraordinary specific capacity of over 250 mAh g −1 and high energy density of over 1 000 Wh kg −1. The superior capacity of LRMs originates from the activation process of the key active component Li 2 MnO 3.
