Solid-state batteries are becoming the next big thing in energy storage, with the promise of low volatility, high energy density and lower-cost manufacturing.  With academia, industry and government collaborating on the next wave of development, we may see progress in this realm. Recently, the Department of Energy’s Oak Ridge National Laboratory and Solid Power Inc. of Louisville, Colo., signed an exclusive agreement licensing lithium-sulfur materials for next-generation batteries. A team of current and former ORNL researchers including Chengdu Liang, Nancy Dudney, Adam Rondinone, Jong Keum, Jane Howe, Wujun Fu, Ezhiylmurugan Rangasamy, Zhan Lin and Zengcai Liu developed the technology.  This included designing and testing an all-solid lithium-sulfur battery “with approximately four times the energy density of conventional lithium-ion technologies.”  It featured a …

Two “New” Battery Contenders

With Tesla’s announcement that its new battery pack for its Rev. 3 Roadster will increase the car’s range to as much as 400 miles (your mileage may vary), two contenders are putting proclaiming equivalent or better performance from their unique technologies.  These companies are relatively new, but have fairly long development histories.  They are both moving toward commercializing what otherwise would be academic demonstrations of their technologies. EnerG2 – Taking Carbon to New Levels A Seattle, Washington-based materials development firm, EnerG2’s Carbon Technology Platform (CTP), is based upon a polymer chemistry foundation, and according to the company, “represents an ability to engineer and synthesize high-performance, uniquely tailored high-purity carbons, at large scale and low cost.”  The company makes CTP materials …
