In the conventional technology, silicon had to be pulverised to 100 m and coated with carbon to prevent silicon destruction and secure lifespan.
Our new coating technology maintains the coating film stably even on 300mm silicon and prevents the destruction of silicon. We selected 1um plate-shaped silicon as the most suitable material for new anode technologies, and our uniform prevention coating is formed on the plate-shaped material with carbon layer. This technology enables high -capacity & long-life lithium ion battery.
The most ideal price of a silicon anode material is that the price rises as much as the capacity multiplier of graphite. However, the current price of silicon anode material is 8 times, but the capacity is 5 times the capacity of graphite. A 40 % drop from the current price is required to meet the ideal expectation. The reason for such a high price is that silicon metal price is cheap enough, but the production rate is slow in conventional production process.
To solve the economic problem, we have focused on designing a process suitable for high production speed.As a result, we have developed a process with 3 times higher speed consider with the input capital. Through the efforts of the two years, we have sufficiently secured the economic feasibility of production and supply price, which were difficult with conventional processes.
