Lithium ion batteries are already among the most popular for portable electronics, having a superior energy-to-weight ratio and a slow loss of charge when not in use. To be commercially viable for transportation, however, Li-ion batteries will need to last 10 to 15 years; their cost will have to be significantly reduced and their safety improved.
