The high-tech patent wars have spread to a new front, engaging two of the world’s largest industrial companies in a multibillion-dollar court battle over lithium-ion batteries. At issue is a battery chemistry that, while little known to the public, many experts believe currently holds the best chance of electric cars penetrating the mass market. The …

In today’s lithium batteries, those cathodes are usually made of an orderly crystalline material, sometimes in a layered structure. When slight deviations from that perfect order are introduced, the battery’s efficiency generally goes down — so disordered materials have mostly been ignored in the search for improved battery materials.
