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

Green Car Congress

A team of researchers at the University of California, Riverside has developed an approach to addressing the vexing problem of dendrite formation that hobbles the use of high energy density lithium-metal anodes in advanced recyclable batteries. The earliest non-rechargeable Li batteries using Li metal as anode appeared in the 1970s.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years. The discovery came when MIT researchers Byoungwoo Kang and Gerbrand Ceder found out how to get a common lithium compound to release and take up lithium ions in a matter of seconds.

KIT/IIT team demonstrates suitability of high-entropy oxides (HEO) as conversion materials for reversible energy storage

Green Car Congress

Novel materials can considerably improve storage capacity and cycling stability of rechargeable batteries. Recently, a new class of oxide systems, also known as high entropy oxides (HEO), was formulated and reported with first demonstrations for transition-metal-based HEO (TM-HEO), rare-earth-based HEO (RE-HEO) and mixed HEO (TM-RE-HEO).

Three Battery-Electric Opel Merivas to Participate in MeRegioMobil Research Project; Vehicle-to-Grid Integration

Green Car Congress

Opel will use MeRegioMobil to study new intelligent charging technologies. The electric Meriva features electronic controls which permit high power electrical recharging using both a 230-volt single-phase household current as well as 400-volt three-phase AC. Charging time with 230V is approximately 3.5
