Since lithium-ion batteries were first sold 30 years ago, they’ve dropped in cost by 97%. But they’re still too expensive for making electric cars that can compete in cost with fossil-fueled cars without subsidies, or to economically store wind and solar power on the grid. That’s why one Boston-area startup is developing a different type of rechargeable battery that it says can cut costs in half-while avoiding some of the other flaws of current batteries, from the environmental impact of mining to the fact that lithium-ion batteries can catch on fire.
