U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

More nickel in a battery means it can store more energy. Ni NMA outperforms both NMC and NCA and only slightly trails NMCAM and a commercial cathode after 1000 deep cycles. The team reported a new class of cathodes anchored by high nickel content. The cathode in their study is 89% nickel.

Williams Hybrid Power flywheel proves powerful and reliable in Porsche 911 GT3 R Hybrid in Zhuhai race

Green Car Congress

WHP’s patented Magnetically Loaded Composite (MLC) flywheel technology, originally developed for Formula One, captures and stores a vehicle’s kinetic energy in a high-momentum composite flywheel. At the core of the hybrid system is Williams Hybrid Power’s (WHP) flywheel energy storage unit. Earlier post.).

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 full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.
