Researchers from the Korea Institute of Science and Technology (KIST) claim to have developed a sulfide-based superionic conductor—a material with high ion transport properties corresponding to ion conductivity of 10 to 100 mS/cm at room temperature—that can be used as a high-performance solid electrolyte in all-solid-state batteries. All-solid-state battery technology could solve the safety issues… Read more »

Researchers make Ceramic-based flexible electrolyte sheets for lithium metal batteries
Researchers at Tokyo Metropolitan University have developed a new method to make ceramic-based flexible electrolyte sheets for lithium metal batteries. They combined a garnet-type ceramic, a polymer binder, and an ionic liquid, producing a quasi-solid-state sheet electrolyte. The synthesis is carried out at room temperature, requiring significantly less energy than existing high-temperature (>1,000° C) processes…. Read more »
Samsung researchers describe all-solid-state battery with silver-carbon composite layer
Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) have published a study on high-performance, long-lasting all-solid-state batteries in the journal Nature Energy. Compared to lithium-ion batteries, which employ volatile liquid electrolytes, all-solid-state batteries use non-volatile solid electrolytes that support greater energy density. However, their lithium metal anodes… Read more »
New report: Cost and performance of batteries improving much faster than forecast
A new report from the Rocky Mountain Institute (via Forbes) finds that improvements in the cost and performance of batteries are quickly outpacing forecasts, due to massive investments in battery manufacturing and steady advances in technology. According to RMI’s Breakthrough Batteries Report, venture capital firms invested over $1.4 billion in battery tech in the first… Read more »
Piotrek and CSIRO partner on solid-state battery research
Australia’s national science agency, CSIRO, and Japanese chemical manufacturer Piotrek have partnered to produce the next generation of solid poly electrolytes (SPEs) for lithium batteries, using Piotrek’s ion conducting polymers (ICP) and CSIRO’s reversible addition-fragmentation chain transfer (RAFT) polymer technology. Piotrek General Manager Ihei Sada said, “This partnership will help Piotrek make our batteries safer… Read more »
UCLouvain discovers new solid-state material with high lithium diffusion coefficient
As research into solid-state lithium batteries continues, researchers at Belgium’s Université catholique de Louvain (UCLouvain) say they’ve found a new solid material, LTPS, in which lithium can travel more easily than in any other solid electrolyte. The results are published in the scientific journal Chem from Cell Press. Lithium ions are much less mobile in… Read more »
Imec doubles energy density of its Li-metal batteries to 400 Wh/liter
Imec, a Belgian research firm focused on nanoelectronics, has unveiled a solid-state Li-metal battery cell with an energy density of 400 Wh/liter at a charging speed of 0.5C (2 hours). As part of a larger engineering roadmap for solid-state batteries, imec aims to surpass wet Li-ion battery performance and reach 1,000 Wh/L at 2-3C by… Read more »
LISA project aims to develop Li-S battery cells with solid-state non-flammable electrolytes
Lithium-sulfur is seen as one of the most promising chemistries for the next generation of batteries, and the UK battery firm OXIS Energy has been developing the technology for some time. Now OXIS has announced that it will be one of 13 European partners in the Lithium Sulfur for Safe Road Electrification (LISA) project, which… Read more »
Hyundai invests in solid-state battery materials specialist Ionic Materials
Hyundai’s venture capital division, Cradle, is investing in Massachusetts-based battery materials developer Ionic Materials. Ionic says its patented solid polymer material enables solid-state batteries that are inherently safe, high in energy density and operational at room temperature. The special properties of Ionic’s polymer electrolyte also support lithium-ion cells with little to no cobalt in their cathodes…. Read more »
