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

Green Car Congress

This energy sector is primarily driven by the need for low-cost with reasonably long cycle-life energy storage technology, for which the lead-acid battery is well suited. 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.

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. The electrode can be continuously deep cycled up to 5,000 times without significant capacity decay. Click to enlarge. At a charge/discharge current of 1.0

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Their low cost and ability to start the engine at cold temperatures sets them apart in conventional and basic micro-hybrid vehicles, and as auxiliary batteries in all other automotive applications, according to the report. In these applications, they are currently the only technology available for the mass-market.
