Development of an electric car battery able to compete with the internal combustion engine may be five years away, U.S. Energy Secretary Steven Chu said.
The storage capacity of current electric car batteries needs to be increased by a factor of six or seven times in order to be acceptable to car drivers, Chu said. Their lives need to be extended to 15 years, and the cost needs to be reduced by a factor of three, he said.
