Michigan-based battery upstart Our Next Energy is tackling energy density, cost and safety with a new approach to cell chemistries. "When I look at our 'toolbox,' we've got one cell chemistry that delivers high energy density, is low cost, but it doesn't have optimum cycle life," veteran battery engineer Mujeeb Ijaz noted. "And we've got another cell that's super-good at cycle life. We realized that given about 99 percent of EV duty cycles, we don't need a single cell chemistry to solve all the problems. We can just use two."
