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. Therefore their cycle life, power density and charge acceptance will need to be further improved.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Ioxus , a young (2006) ultracapacitor spin-off from Custom Electronics, an established supplier of high-reliability capacitors to commercial and military clients since 1964, is targeting the development of higher power density, compact ultracapacitors, applied in a full range of applications spanning military, industrial and automotive needs.

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

And besides technical improvements, the systems will need to be built to last, using materials that are safe and durable so that batteries could operate more than 15 years and require very little maintenance over their lifetime. In addition, it can provide services to solve more localized power quality issues and reactive power support.
