Scientists at the Paul Scherrer Institute (PSI) and the Toyota Central R&D Labs have reported a memory effect in lithium-iron phosphate (LiFePO4) batteries that appears after only one cycle of partial charge and discharge. Memory effects are well known to users of nickel-cadmium and nickel-metal-hydride batteries. If these batteries are recharged repeatedly after being only partially… Read more »

Rich Byczek on delayed battery overheating and stranded energy
(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) EV standards gaps: Intertek’s Rich Byczek on two of the biggest safety concerns centered around batteries. The EV industry is young and evolving quickly – too quickly, in some cases, for the standards community to keep up. The competing charging standards provide the most obvious example. There are… Read more »

Accelerating battery development, part 2: Wildcat Discovery Technologies
Wildcat Discovery Technologies is a venture-backed start-up residing in sunny San Diego. Launched in late 2006, it makes efficient use of just 32 employees. The company has developed proprietary methods for rapidly synthesizing energy-storage materials. Serial entrepreneurs Prof. Peter Schultz and Robert Downs have worked together for a number of years at the Genomics Novartis… Read more »
Toyota to recycle used NiMH batteries into electricity management systems
By improving the usage efficiency of electricity – for example, by cutting the amount used during peak usage times – the new system can cut the cost of electricity and gas used by half
New Ford battery test simulates 10 years of use in 10 months
A recent Ford survey found that battery reliability ranks as the single most important consideration for potential hybrid customers – topping 17 other factors, including fuel economy and safety features.1
Three of a kind: PolyPlus reaches for 1,500 Wh/kg
After decades of patent-protected breakthroughs, PolyPlus stands poised to make its first commercial move from its trio of power-dense battery technologies: lithium-sulfur, lithium-water, and lithium-air. It’s a balmy, 95-degree August day in the nation’s capital, but Steven J. Visco, PhD, the CEO, CTO, and co-founder of PolyPlus, sits in the climate-controlled comfort of the White House… Read more »
ARPA-E awards $43 million to 19 energy storage projects
