There are various methods for modifying cathode materials, such as elemental doping, coating, heterostructure construction, and single-crystalline cathodes. While these methods can improve electrochemical performance, their specific impact on battery safety needs to be better understood.
To improve battery safety, it is important to uncover the fundamental reasons behind cathode active material failures. Innovative strategies for modifying cathode active materials to enhance safety properties, including thermal stability, oxygen retention, and particle integrity, should be explored.
Policies and ethics New and improved cathode materials for better energy storage are the urgent need of the century to replace our finite resources of fossil fuels and intermittent renewable energy sources. In this chapter, an attempt is made to focus on the progress made in the field...
In this chapter, an attempt is made to focus on the progress made in the field of cathode materials for lithium ion batteries (LiBs) in recent years in terms of achieving high energy and power density, and good capacity retention over multiple cycles and safety.
Therefore, most investigations to date utilize copper as the active cathode materials. When a Cu-based cathode is coupled with a low electrode potential anode such as Li and Al−Li alloy, the corresponding battery will have an output voltage of about 3 V.
Cathode materials The positive electrode, known as the cathode, in a cell is associated with reductive chemical reactions. This cathode material serves as the primary and active source of most of the lithium ions in Li-ion battery chemistries (Tetteh, 2023).
