Breakthrough for electric cars: Supercapacitors from miracle substance graphene charges batteries in 4 minutes

The problem of limited range has been an important factor curbing the wide-spread adoption of electric cars. But scientists in South Korea have developed a new technology which could solve the problem.

The lithium-ion batteries used in most of the current generation of electric cars have limitations. They are expensive and store insufficient power for the needs of many drivers, requiring frequent top-ups. And when they have to be recharged the charging process is time consuming.

The technological breakthrough could solve these problems. And in the process, Dr Lu Wu of the Gwangju Institute of Science and Technology in South Korea has discovered a new use for the miracle substance graphene.
