Electric vehicle consumers seek a comfortable range for their batteries. As the world’s vehicle fleet decarbonizes by transitioning to electric drivetrains, the answer to what makes the best battery solution remains elusive. The one flat plateau at 2.1 V and a capacity of around 110 mAh g 1 at 0.2 C are the characteristic behavior of NaTi 2 (PO 4) 3 electrodes, indicating that the H-NASICON can function effectively as a solid electrolyte in an all-solid-state sodium battery. There is still work remaining in order for the technology to become commercially available, but this discovery may pave the way for all-solid-state batteries to become commercialized. ASU engineering faculty member Candace Chan and team work to advance solid-state battery technology. They provide an opportunity for a cost-effective means to smooth the electricity from intermittent renewable energy sources, especially solar. PotentialĪll-solid-state batteries can be used as electric vehicle batteries or stationary storage to support intermittent renewables, contributing to the reduction of greenhouse gas emissions. Testing has revealed that the battery is able to operate efficiently at a wide range of temperatures, between -30 and 100 degrees Celsius while a conventional lithium ion cell showed very low discharge capacity at -30 degrees and couldn’t operate at 100 degrees. This is part of a project with the New Energy and Industrial Technology Development Organization (NEDO), the Japanese government agency which supports innovation in renewable energies and environmental and industrial technologies. They have been applied to develop an all-solid-state battery that has achieved a power density three times as high as the conventional lithium-ion batteries. Toyota Motor Corporation and the Tokyo Institute of Technology have discovered superionic conductors with the world’s highest lithium-ion conductivity. All-solid-state batteries are a promising solution to creating a high-capacity and highly-powered battery of the future. All-solid-state batteries (all-SSBs) have emerged in the last decade as an alternative battery strategy, with higher safety and energy density expected 1. Conventional lithium-ion batteries, which use liquid electrolytes, are reaching the upper limit of energy density and facing challenges concerning limited operation temperature.
