Battery entrepreneur releases new invention to reduce cobalt

Tour of Tesla battery gigafactory for invited owners, Reno, Nevada, July 2016As other battery scientists are working to develop the solid-state lithium batteries of tomorrow, technology entrepreneur Kenan Sahin is working to make the batteries of today more affordable. Sahin announced at a conference in Berlin this week that his company TIAX has invented a new battery compound that he calls GEMX that reduced the need for...

Commentary: Want faster electric-car charging? Pony up!

Volkswagen MEB platform architectureThe future may be coming for electric cars, but it's not yet clear what it will look like. When modern electric cars first launched between 2011 and 2014, many shared similar specs: about 80 miles of range, overnight charging, a five-passenger hatchback body, and a price starting around $28,000 before tax credits. Some models offered bigger...

VW confirms it’s planning for solid-state batteries by 2025

Thomas UlbrichSolid-state batteries sometimes sound a bit like the missing link that would punt electric vehicles soundly into mainstream acceptance. The list of potential virtues for solid-state tech, which would replace the polymer/gel electrolyte commonly used in lithium-ion cells with a solid one, is impressive: a longer driving range; smaller packaging;...

Renault plans Europe’s largest battery storage network

Renault utility storage network to deploy used electric car batteries in France and GermanyEuropean electric-carmaker Renault plans to build the continent's largest stationary battery storage network next year using old electric-car batteries. Renault announced on Tuesday that it will install used (and some new) electric car batteries in three locations: two Renault factories in France, and the site of a former coal-fired power plant in...

Iron triflouride could make better electric-car batteries

Adding oxygen and cobalt to the cathode prevents lithium from breaking chemical bondsResearchers at the University of Maryland, in conjunction with Brookhaven National Laboratory have developed a new battery cathode material that they say could triple the energy density of lithium-ion batteries. The new material is an engineered variety of iron trifluoride, a well-known material that has had problems with rechargeability and low...

PG&E, Tesla team up to boost battery backups for power grid

Tesla PowerpacksUtilities are racing to expand battery storage on the electrical grid. The latest example is Pacific Gas and Electric Co., which submitted a request Friday to the California Public Utilities Commission to build and install four large banks of lithium-ion battery storage, according to the San Francisco Chronicle. The projects would include Tesla's...
