However, there was a disadvantage in using silicon because silicon contains more lithium ions than graphite which was more likely to expand in size. As a result, its usage was very limited even when silicon was used as an anode material. The fact that LG Energy Solution developed and planned to test pure silicon prototypes is interpreted as the company achieving significant technological improvements.

By reducing the size of silicon to the current minimum level of 5 micrometers (㎛), LG Energy Solution solved this problem. The silicon will be able to contribute in not only improving performance but also in reducing the volume of the battery. This will improve long-distance driving and charging performance once it commercializes, as well as securing battery price competitiveness by using silicon, which is cheaper than graphite.

LG Energy Solution is cooperating with domestic and foreign material companies to improve the performance of pure silicon. It is in the process of developing by collaborating with companies such as silicon material companies that make nanoparticles, and conductive material and binder companies, which are used as additive materials for silicon. The establishment of a preliminary supply chain to mount pure silicon batteries in future EVs has begun.
