KIST team develops activation strategy for magnesium metal enabling efficient operation of Mg batteries

Green Car Congress

Despite these advantages, the difficulty of efficiently charging and discharging magnesium metal due to its reactivity with electrolytes has hindered its commercialization. It will increase the possiblity of low-cost, high-energy-density magnesium secondary batteries based on common electrolytes suitable for energy storage systems (ESS).

Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

Plug-in hybrid vehicles often are not recharged regularly, which implies driving is often performed on the combustion engine. Statistically, private users of vehicles in Germany re-charge their plug-in hybrid vehicle only on three out of four days. Company car users, on average, re-charge only every second day.

UC Riverside team develops new coating strategy for Li-metal anodes to prevent dendrite formation

Green Car Congress

For these purposes, many high-capacity cathode (including Li−sulfur and Li−air) and anode materials (Li metal, silicon, tin, and metal oxide) have recently re-emerged. Among these materials, Li metal is the ideal anode material for rechargeable Li batteries due to its various advantages including low redox potential (−3.04

PSA evaluating PowerGenix NiZn batteries for start-stop systems

Green Car Congress

Start-stop systems shut off engines while the vehicle is at rest and restart it instantly and automatically upon re-engaging the gas pedal and are one of the most cost-effective and efficient means of optimizing fuel economy. Lead-acid batteries, the most common battery choice, are low-cost, easily available and relatively safe.

MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

In an open access paper in the journal Nature Communications , they reported that the Al yolk-shell anode achieved a 10 C charge/discharge rate with reversible capacity exceeding 650 mAh g −1 after 500 cycles, with a 3 mg cm −2 loading. The charge/discharge rate was set at 1 C. The charge/discharge rate was set at 1 C. (b)
