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

Green Car Congress

Advanced lead-based batteries (AGM and EFB technologies) are installed to meet extra requirements in start-stop and basic- micro-hybrid vehicles, due to their increased charge recoverability and higher deep-cycle resistance. In these applications, they are currently the only technology available for the mass-market.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

In comparison, energy management, such as load shifting, requires systems of up to MWh or even GWh levels that are capable of discharge durations up to a few hours or more at designated power. This type of application requires high round-trip energy efficiency and a long deep-cycle life, along with low operation and maintenance costs.
