Truewin, which is promoting the development project of silicon anode materials, announced on the 20th that it commissioned the mobile consumer survey company Kratos to conduct a survey on 'electric vehicle perception.' Among 2,004 respondents, 43.5% answered that 'battery charging time needs to be improved.' Among the respondents, 34.8% replied that 'the driving range after a full charge is unsatisfactory.' Seven out of ten respondents judged that the performance of electric vehicle batteries needs to be improved.
A Truewin company official explained, "Through the survey, we identified that consumer demand for improving electric vehicle charging time and driving range is quite high," adding, "Increasing energy density with silicon anode materials will be a game changer in boosting electric vehicle demand."
An official from the joint development company NM Tech said, "If the proportion of silicon anode materials exceeds 10%, the electric vehicle charging time, which usually takes more than 30 minutes, can be reduced to about 5 minutes."
Silicon anode materials have the risk of swelling during battery charging and the expanded anode not returning to its original shape during discharge. The battery industry is conducting research and development to improve the side effects of battery volume expansion.
Truewin is building a 100-ton scale silicon anode material production facility. NM Tech's core technology is the hydrothermal synthesis method. It changes the existing anode material manufacturing method, which combined solid and solid, to a chemical reaction combining liquid (silicon tetrachloride) and liquid (ethylene glycol), reducing raw material costs.
The company explained that the manufacturing process also uses a low-temperature heat treatment process, lowering the temperature by 450~700℃ compared to the existing method, and has more than 30% price competitiveness compared to anode materials developed by major domestic companies.
