SEOUL, KOREA – A Korean research team has developed a key technology that will shorten the charging time while doubling battery life.
On Wednesday, the Korean research team, composed of Jin-woo Lee (professor of chemical engineering at Pohang University of Science and Technology (Postech)), doctoral candidate Jong-kuk Hwang and Kyu-tae Lee (professor of eco-friendly energy engineering at Ulsan National Institute of Science and Technology or UNIST), announced that it successfully synthesized carbon-silica composites based on tin (Sn) - which is used as a cathode material for lithium ion batteries- by using a facile “one-pot” method. The team’s research achievement was introduced in ACS Nano (a monthly, peer-reviewed, scientific journal published by the American Chemical Society).
The carbon-silica composite synthesized by the team is capable of taking the lithium battery charging time (which is usually three to four hours) down to less than one hour and doubling its battery life.
There has been an urgent need for the development of new anode materials for lithium ion batteries since Graphite, which is most widely used as anode material, is relatively low in capacity.
