New highly conductive solid electrolyte with improved electrode contact for solid-state Li-ion batteries
New highly conductive solid electrolyte with improved electrode contact for solid-state Li-ion batteries 31 December 2015 A joint research team from Ulsan National Institute of Science and Technology (UNIST) and Seoul National University in Korea, with colleagues at Lawrence Berkeley National Lab and Brookhaven National Lab in the US, has developed a new highly conductive (4.1 × 10−4 S cm−1 at 30 °C), highly deformable, and dry-air-stable glass 0.4LiI-0.6Li4 SnS4 electrolyte for solid-state Li-ion batteries. The electrolyte is prepared using a homogeneous methanol solution. The process enables the wetting of any exposed surface of the electrode active materials with the highly conductive solidified electrolyte, resulting in considerable improvements in electrochemical performances. A paper on the work is published in the journal Advanced Materials . Most efforts on the dev...
