    No cobalt, no Tesla?

    The battery industry uses 42 percent of global cobalt production, critical for Lithium-ion cells. Much of the world’s supply of cobalt comes out of Africa. Chinese players recently bought controlling stakes in one of Africa’s largest known cobalt sources. Tesla has stated that the cobalt it needs will be sourced in North America, but the math doesn’t add up. Is Tesla doomed? Read More

    This battery is powered by bacteria

    Researchers at Binghamton University in New York have created a “bacteria-powered battery on a single sheet of paper.” The project is aimed at creating batteries for disposable microelectronics that can run for weeks using a little bacteria-rich liquid. “The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as… Read More

    Used BMW i batteries store solar power at home

    BMW i joins Tesla and Mercedes-Benz in bringing energy storage home with its new system, which has yet to be given a catchy name. The system uses new or used batteries from the BMW i3 electric car to store power from solar panels for later use. It integrates with the charging station users are likely to have in the garage, so the stored energy from the sun can power your i3… Read More

  • New technology extends lithium-ion battery life

    A Japanese company called Eamex claims it has found a way [JP] to increase the life of high-capacity lithium-ion batteries (that can be used in electric vehicles). Eamex says the new batteries can be charged and discharged over 10,000 times. Apparently, they can last about 20 years, too. Read More

  • New battery material could boost efficiency of electric cars by a factor of ten

    Electric cars have one major problem: Especially in the case of long drives, owners have to make too many stops to charge the battery. Now a group of researchers from Toyota and Tohuku University (in Northern Japan) announced progress on their work to do away with this inconvenience. They were able to make single crystals of lithium cobalt oxide, a chemical compound used in the production… Read More
