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

Green Car Congress

The Pb-acid SLI battery will still continue to be in demand for the many small and cheap ICE vehicles where cost of the battery replacement will always be the deciding factor. 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. Schuldt, J.

Stanford, SLAC team cages silicon microparticles in graphene for stable, high-energy anode for Li-ion batteries

Green Car Congress

The graphene cage acts as a mechanically strong and flexible buffer during deep cycling, allowing the silicon microparticles to expand and fracture within the cage while retaining electrical connectivity on both the particle and electrode level.
