Safer, Longer-Lasting Batteries for Cars
Abstract:
An Orlando startup has developed new manufacturing techniques that could improve the stability and lifetime of batteries used in electric vehicles. Planar Energy, a spin-off of the National Renewable Energy Laboratories (NREL), is working on scaling up solid-state lithium-ion batteries.
Planar Energy has developed a roll-to-roll process for making larger solid lithium-ion batteries. The company, which received $400,000 in funding from the Advanced Research Projects Agency Energy program this spring, says it can print solid batteries that offer three times more storage than liquid lithium-ion batteries of the same size. This boost in energy storage is possible primarily because the company's all-solid batteries don't require many of the support structures and materials that take up space in conventional batteries, making more space for energy storage.
