LIBs were first adopted in small IT devices such as note PCs and HHP and has expanded their territory into various applications including electric vehicles and energy storage systems.  Requirements for LIBs vary from application to application

 

The R&D on LIBs has been mainly directed toward high capacity, high output, low price and high safety.

 

Since the first commercialization in 1990, LIBs have constantly evolved in terms of performance.  Taking cylindrical batteries as an example, their capacity has increased by 2 times but prices declined to less than 쩍.  Nevertheless, the efforts to achieve high capacity is progressing slowly because little progress has been made in securing low-cost, high capacity materials for LIBs.

 

Due to the slow progress in securing high performance materials, the development of high capacity LIBs has slowdown.  To overcome this challenge, there are aggressive efforts, focused on the 4 key components.  Among them, the development of cathode materials is directed to achieving high capacity by increasing the charging voltage of cathode materials.

 

This report introduces the current trends in the development of cathode materials with high voltage charge capacity and challenges, proposing the directions for future R&D activities.
