Automotive segment consumes 10.5% of global advanced battery production

Batteries are big business. According to the latest Advanced Battery Tracker from Navigant Research, more than 6 billion advanced battery cells were sold in 2013, representing 40 gigawatts of power capacity and more than $13.4 billion in sales (a modest increase over 2012’s $12.8 billion). The majority of these batteries were manufactured in China. Most… Read more »

A123 acquires start/stop battery technology from Leyden Energy

A123 Systems is back in the news. The battery-maker, now a wholly owned subsidiary of China’s Wanxiang Group, has acquired Leyden Energy’s intellectual property in battery materials covering lithium titanate (LTO) and non-flammable electrolyte (Li-imide) technology. As part of the deal, some of Leyden’s key technical staff will be joining A123’s R&D organization.    … Read more »

Minnesota mandates special electricity pricing for EVs

Time-of-use electricity pricing is a good deal for all concerned. It allows consumers to save money, and it helps electric utilities to better manage their grids, by encouraging people to shift electrical usage away from peak demand periods. And of course, it provides yet another incentive to drive electric – it’s easy to schedule charging… Read more »

Results of California EV buyer survey now available online

The California Air Resources Board has published the results of a survey of plug-in vehicle buyers who received rebates from the state. The online data is available for researchers, policymakers and the public to learn about who is buying plug-in cars (PEVs) in California, and why. Between March 2010 and March 2014, about 191,000 PEVs… Read more »

Swedish researchers: Carbon fiber can serve as both body panel and battery

It’s one of the dilemmas of EV design: It’s imperative to keep a vehicle’s weight as low as possible, but the most critical component – the battery – is necessarily quite heavy (and bulky). A little outside-the-box thinking yields an elegant solution – make the box the battery. In other words, design a battery material… Read more »

Lithium iron phosphate electrodes reveal exotic state of matter to MIT researchers

Transmission electron microscopy has allowed MIT researchers to directly observe a lithium iron phosphate (LiFePO4) electrode during charging, and they found that, just as suspected, a solid-solution zone (SSZ) forms at the boundary between lithium-rich and lithium-depleted areas, as lithium ions are pulled out of the electrode. The new findings, which appear in a paper… Read more »
