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.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Ioxus says that the power density of its 100F carbon-carbon ultracapacitor solutions is 2x over that of competitive comparable 100F cells. On the larger cells, such as the 2000F, Ioxus offers 20% more power than Ness, is at parity with Maxwell, and is higher in volumetric density, according to the company.
