Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

The researchers considered aspects of safety, cost, design and testing specifications n light of the emerging European battery legislations on the use of restrictive materials in vehicles. There will still be a need for a 12 V battery for the supply of auxiliary power that will not necessarily be a Pb-acid SLI battery. —Ferg et al.
