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). Both use an alkaline electrolyte and a nickel electrode but differ significantly in their voltage.

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. Nanotune Technologies’ CEO Kuang Tsei Huang has demonstrated supercapacitors with 35 Wh/kg, saying that 500 Wh/kg may be achievable, 2-4 times the energy density of the best Li-ion batteries, IDTech notes.

Alstom to supply two H3 hybrid shunting locomotives for Audi

Green Car Congress

The powertrain consists of a 350 kW diesel generator and a 350 kW NiCd battery. Whereas the old traction vehicles consume over 20 liters of fuel per hour, the generator of the hybrid locomotive, which is needed only to charge the battery block, requires a maximum of nine liters per hour.

Microporous polymer material for supercapacitors with large capacitance, high energy and power densities and excellent cycle life

Green Car Congress

The energy density is higher than those of nanostructured porous carbon materials and reaches the regime of batteries such as Pb-acid, NiCd, and lithium ion battery (10–150 Wh kg -1 ). The Ragone plot reveals that Aza-CMPs exhibit the maximum energy and power densities of 53 Wh kg -1. kW kg -1 respectively. kW kg -1 ). Stability.
