Zinc batteries have a relatively low efficiency-meaning more energy will be lost during charging and discharging than happens in lithium-ion cells. There are some technical challenges that zinc-based and other alternative batteries will need to overcome to make it to the grid, says Kara Rodby, technical principal at Volta Energy Technologies, a venture capital firm focused on energy storage technology. The company’s batteries are also designed to have a longer lifetime than lithium-ion cells-about 20 years as opposed to 10 to 15-and don’t require as many safety measures, like active temperature control. “It’s a fundamentally different way to design a battery, really, from the ground up,” he says.Įos’s batteries use a water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent, which makes them more stable and means they won’t catch fire, Richey says. Zinc-halide batteries have a few potential benefits over lithium-ion options, says Francis Richey, vice president of research and development at Eos. Zinc-based batteries aren’t a new invention-researchers at Exxon patented zinc-bromine flow batteries in the 1970s-but Eos has developed and altered the technology over the last decade. ![]()
