Planar Energy, a spin-off of the National Renewable Energy Laboratories, has quietly been developing solid-state battery technology and remains convinced that the future of electric vehicle batteries is solid-state technology. The Orlando-based company believes that its solid-state design could potentially offer more power output and higher energy storage density than a typical lithium ion battery. As Planar Energy notes, typical lithium ion batteries lack stability and longevity due to undesirable chemical reactions that can occur in the liquid-based electrolytes. If you replace the reactive liquid electrolyte with a solid ion conductor, the solid-state battery is born.
Up until now, solid-state battery technology has been difficult to scale up to the size required by the automotive industry. Planar Energy claims to have solved the issue by developing a roll-to-roll deposition process that allows larger solid-state batteries. Planar Energy will build a pilot production line next year and hopes to begin manufacturing its batteries for high-tech electronic devices. If all goes as planned, the company will scale up efforts and begin development work on automotive batteries. Follow the jump to learn more about Planar Energy's recent advancements in solid-state battery technology. Hat tip to David!
