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 »

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 »

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 »
