Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

A team from Lawrence Berkeley National Laboratory and Tsinghua University (China) have synthesized graphene oxide-sulfur (GO-S) nanocomposite cathodes and applied them in lithium/sulfur cells to show a high reversible capacity of 950-1400 mAh g -1 and stable cycling for more than 50 deep cycles at 0.1C (1C = 1675 mA g -1 ).

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.

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

Compared to advanced lead-acid batteries, the PbC batteries: Support higher [10-20x] charge acceptance and faster recharge [5-10x] in partial state-of-charge (PSOC) applications; Offer an 4x increase in cycle life in 100% depth-of-discharge applications; and. This limits the ability of battery to take on recharge. Micro-hybrids.
