Korean scientists develop fast-charging battery

Summary: Scientists in South Korea say new development cuts down recharging time to between 1/30 and 1/120 of existing lithium-ion batteries and could boost uptake of electric vehicles when developed.

South Korean scientists have developed a new material for rechargeable lithium-ion batteries that they say could cut charging time down significantly and prove a boon for electric vehicles.

According to Yonhap News Agency’s report on Monday, a group of scientists from Ulsan National Institute of Science and Technology, who were funded by the country’s Ministry of Education, Science and Technology, has gone beyond conventional rechargeable battery technology.

Conventional batteries use powdered nanoparticle materials to form a dense, multi-layered structure that can store and give off energy, it noted. The new battery will use the same nanoparticle materials, but these will be in the form of a solution that contains graphite which will later carbonize to form a dense network of conductors throughout the electrodes of the battery, the ministry stated in the report.
