Asia: Battery power that’s cheaper and lasts longer

Above: Dr Saravanan Kuppan (centre) is one of five NUS PhD graduates who won the World Future Foundation PhD Prize in Environmental and Sustainability Research this year.

His work deals in materials that are tiny but the rewards for humankind promises to be big.

For his work, Dr Saravanan Kuppan from the National University of Singapore (NUS) Faculty of Science was honoured recently.

He was one of 10 PhD students who were presented with the recent WFF PhD Awards in Environmental and Sustainability Research on July 11.

Dr Saravanan developed mesoporous titanium dioxide (TiO2), which has excellent energy storage properties when used in lithium-ion batteries.

The mesoporous TiO2 that he made has very small pore size – in the range of 5 to 10 nanometres (one nanometre is equal to one billionth of a metre) – and an application has been made to have it, as well as its application in electrochemical devices, patented in the United States.

In addition, the material was mass produced and a novel lithium-ion battery was developed for electric vehicle application in collaboration with E-One Moli, the third largest battery manufacturer in Taiwan.
