Volvo Buses in project researching use of second-life electric bus batteries to store solar energy

Green Car Congress

Volvo Buses is participating in a research project in which used electric bus batteries are used as solar energy storage units. Batteries from electric bus route 55 in Gothenburg, Sweden are being used for solar energy storage in a second-life application. The battery warehouse consists of 14 used lithium-ion electric bus batteries.

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. The combination affords a Mg battery that delivers a specific power of up to 30.4?kW?kg —Dong et al.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. But large-scale deployment has been a challenge.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

LLTO anode material for safe batteries with a long cycle life

Green Car Congress

Researchers at Karlsruhe Institute of Technology (KIT) and Jilin University in Changchun/China have investigated a highly promising anode material for future high-performance batteries: lithium lanthanum titanate with a perovskite crystal structure (LLTO). Cell voltage and storage capacity ultimately determine the energy density of a battery.
