MIT researchers use semisolid electrode to prevent short circuits in lithium metal batteries

Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »

Project aims to develop a swappable containerized battery system for marine applications

Current Direct, a new €12-million research and innovation project funded by the European Commission, aims to develop a new type of lithium-ion cell, as well as a swappable containerized energy storage system, both optimized for waterborne transportation. The project’s aim is to develop and demonstrate an interchangeable battery system and Energy-as-a-Service (EaaS) platform in an… Read more »

With backing from VW and JB Straubel, QuantumScape stands out from the crowd of new EV stocks

Electromobility companies are going public at a pace that recalls the dot-com frenzy of the 1990s. Yes, history will probably repeat itself to a certain extent—some of these firms will go belly-up, but others will eventually grow into successful and influential players. One that seems particularly promising is QuantumScape, a California developer of solid-state lithium-metal… Read more »

Solid Power introduces all-solid-state lithium metal batteries

Solid Power has announced the production and delivery of the company’s first-generation multi-layer, multi-ampere-hour (Ah) all-solid-state lithium metal batteries.  Solid-state batteries have long been thought of as the “Holy Grail” of EV battery technology, as the lithium metal anode provides more energy and range than today’s Li-ion design, and the solid electrolyte increases safety by… Read more »

Solid-state battery tech: What’s close to commercialization, and what’s still years away?

With a fresh round of funding, Wildcat Discovery Technologies is busy expanding its facilities, building up its battery team and doubling down on promising solid-state research projects. We asked the energy storage experts to help clear up the hype around solid-state batteries. Whenever Charged needs to better understand the complexities of the latest and greatest battery… Read more »

Promising lithium-sulfur active battery material made with low-cost liquid phase process

Scientists at the Toyohashi University of Technology have made an active sulfur material and carbon nanofiber (CNF) composite using a low-cost liquid phase process. Their paper, published in the American Chemical Society’s ACS Applied Energy Materials, claims that all-solid-state lithium-sulfur batteries using a sulfur-CNF composite material show higher discharge capacity and better cycle stability than… 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 »

UC San Diego’s research roadmap for the challenges of solid-state batteries

The race is on to develop batteries that are less expensive, safer, longer-lasting, more energy-dense, and easily recyclable. All-solid-state batteries show promise, but obstacles to their wide-scale adoption remain. In a review article published in Nature Nanotechnology, nanoengineers at the University of California San Diego (UCSD) offer a research roadmap that discusses four challenges of… Read more »

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 »
