Computational design strategy extends battery life

Batteries are wonderful inventions, but like so many things in life, they don’t last. With every charge and discharge cycle, a battery’s capacity is reduced, until eventually it becomes inadequate for its application. “Why does this degradation occur?” muses Northwestern University’s Christopher Wolverton. “In many cases, something probably happened to the cathode.” Wolverton has developed… Read more »

When the company announced plans for its assembly facility in 2015, it… Read more »

Conducting polymer increases the energy efficiency of metal-air batteries

A team of researchers affiliated with the South Korean university UNIST has developed a new way to increase the energy efficiency of metal-air batteries by using a conducting polymer. In “Polypyrrole-assisted oxygen electrocatalysis on perovskite oxides,” published in Energy & Environmental Science, Professors Dong-Gyu Lee, Hyun-Kon Song and Guntae Kim explain that, in the cathode… Read more »

California ARB releases Midterm Review of ZEV regulation, calls for post-2025 standards

In 2012, the California Air Resources Board (ARB) adopted the Advanced Clean Cars (ACC) program, a set of standards for new vehicles through model year 2025. The program has two components: the Low-Emission Vehicle III regulations, which mandate reductions in emissions from legacy vehicles; and the zero-emission vehicle (ZEV) regulation, which requires manufacturers to produce… Read more »
