With most crystal balls indicating an impending mad dash toward electric propulsion, the R&D community is working overtime to solve the thorny problems limiting the market penetration of plug-in vehicles to around 4 percent of global passenger vehicle sales: not enough range or raw materials, and too much mass and cost. Here are some key advances to watch for in battery, fuel cell, and motor technology.
Today’s lithium-ion batteries mostly use lithium nickel manganese cobalt oxide chemistry with a liquid or gel electrolyte. This
