Hydro-Québec commercializing electrolyte patents for solid-state batteries

The University of Texas at Austin has agreed to transfer patents relating to a new type of electrolyte to be used in solid-state lithium batteries to Hydro-Québec, Canada’s largest electricity producer. The patents are co-invented by Dr. John B. Goodenough—a professor at The University of Texas at Austin and the 2019 Nobel Laureate in chemistry—and… 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 »

South Dakota university to create international center for solid-state batteries

The South Dakota School of Mines & Technology plans to establish an international center to develop solid-state batteries. Associate Professor Alevtina Smirnova says the solid-state batteries developed at the new Center for Green Solid-State Electric Power Generation and Storage (CEPS) will be ideal for portable and medical applications, electric grids and the automotive industry. The… Read more »

DOE awards $1.2 million to Wildcat Discovery for improved solid-state batteries

The US DOE has awarded $1,223,833 to Wildcat Discovery Technologies, a company that uses high-throughput methods to develop next-generation battery materials, to develop materials for an all-solid-state battery. Solid-state batteries will allow for higher energy densities and better safety performance, according to Wildcat, which will use the money to explore the development of a composite… Read more »

TeraWatt’s solid-state battery prototype achieves energy density of 1,122 Wh/L

Silicon Valley startup TeraWatt Technology has announced that its prototype 4.5 Ah solid-state battery design achieved a record-breaking energy density of 1,122 Wh/L (432 Wh/kg) in validation tests conducted by third parties, including the Japanese testing service TOYO System. TeraWatt says this 4.5 Ah design, which is branded as TERA3.0, will be available for select… 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 »

New conductor could lead to high energy all-solid-state batteries

Researchers have developed a conductor material that could lead to all-solid-state batteries with the highest energy density achieved to date. Current batteries employ organic liquid electrolytes that are prone to leakage, flammability, and limited energy density, issues which could be eliminated with all-solid-state batteries. The researchers developed a complex lithium superionic conductor that showed high… Read more »

Higher crystallinity results in better solid-state batteries

Scientists at the Tokyo Institute of Technology have been working on solid-state batteries, which are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. They have recently made progress towards overcoming a major limitation of solid-state batteries: high resistance at the interface between the electrodes and the electrolytes… 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 »

Tokyo Tech introduces fabrication process for low-resistance solid-state batteries

Solid-state batteries are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. Unfortunately, they also tend to have relatively high resistance at the interfaces between their electrodes and solid electrolytes, which can limit the rate of charging and discharging. In order to solve this, researchers from the Tokyo… Read more »
