Prime time for batteries Forecasts very on how many, and when, electrified vehicles will hit the streets, but auto and battery makers are ramping up efforts like there's no tomorrow. In energy storage, materials matter Batteries being electrochemical devices, innovation and advances in chemistry and materials are key to what everyone agrees is the need for improved performance and life. Comparing thermal characteristics of Li-ion celss Most Li-ion battery suppliers require that the cell temperature be as uniform as possible to achieve optimal battery performance and avoid battery system failure. But some materials in Li-ion cells have low thermal stability. The world plugs into EVs As matters begin to settle in terms of connector types, charge-station makers are ramping up to meet the needs of a growing population of plug-in vehicles.

Why Volt? After 48 months' development, the 2011 Chevrolet Volt has enetered series production. The pioneering "E-REV" is as important to the mobility industry as it is to GM. Creating the heart of Volt GM's battery requirements meant creating new state-of-the-art in-vehicle engery storage - and doing it in less than four years. Top GM and supplier engineers reveal how they did it. Engineering with maniacal focus A dedicated, cohesive team and a conservative engineering approach put this innovative vehicle into production at moon-shot speed. A unique electrified transaxle Hybrid or not? Definitions aside, what really matters is GM wisely leveraged its next-generation Two Mode propulsion technology to give Volt greater overall efficiency. Sweating the body details Extensive wind-tunnel work gave Volt a shape that's slicker than it looks. But engineers aren't happy with the curb weight.
