The road to longer battery life
Are you sick of your phone’s battery dying after only a few hours? Researchers are hard at work on improving something called the solid electrolyte interphase as a way to boost battery life.
Electric cars: Batteries with brains
The battery is the heart of the electric car. Researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one of the more than one hundred battery cells is defective, it can be replaced easily. Until now, the entire battery had to be replaced.

Self-heating lithium-ion battery could beat the winter woes
A lithium-ion battery that self heats if the temperature is below 32 degrees Fahrenheit has multiple applications, but may have the most impact on relieving winter ‘range anxiety’ for electric vehicle owners, according to a team of researchers.
Scientists demonstrate how to improve ultrathin CIGSe solar cells by nanoparticles
CIGSe solar cells are made of a thin chalcopyrite layer consisting of copper, indium, gallium and selenium and can reach high efficiencies. Since indium is becoming scarce and expensive, it is interesting to reduce the active CIGSe layer, which however decreases the efficiency quite strongly. Now, scientists have produced high quality ultrathin CIGSe layers and increased their efficiency by an array of tiny nanoparticles between the back contact and the active layer.
