IDTechEx sees improving supercapacitors gaining market share against Li-ion batteries

Green Car Congress

Yunasko and others have demonstrated 35 Wh/kg, with the intermediate supercabatteries, matching lead-acid and NiCd batteries. A new report by market research company IDTechEx—“Electrochemical Double Layer Capacitors: Supercapacitors 2014-2024”—finds that supercapacitors are improving faster than lithium-ion batteries in most respects.

Tier 1 HELLA evaluating PowerGenix NiZn batteries for 48V mild hybrid vehicles

Green Car Congress

Nickel-zinc batteries are chemically very similar to nickel-cadmium, NiCd. The PowerGenix battery has up to a third more energy density than a traditional NiCd battery when measured by either weight (Wh/kg) or by volume (Wh/l).
