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 »

VW aims to produce solid-state batteries by 2025
The Volkswagen Group has invested approximately $100 million in California battery QuantumScape, following six years of collaboration with the firm. VW also announced that it aims to have a production facility for solid-state batteries by 2025. VW estimates that solid-state battery technology could more than double capacity compared with its current batteries, for example boosting… Read more »
Toyota, Nissan, Honda, Panasonic partner to develop solid-state batteries
Japan’s New Energy and Industrial Technology Development Organization (NEDO) has launched a public-private project to develop solid-state battery technology. Some 23 companies, including Panasonic, Toyota, Nissan and Honda, are involved. The group has set 2022 as the target date to develop core solid-state technologies, and ultimately aims to lower battery pack cost to $90 per… Read more »
Ionic Materials emerges as a leader in solid-state batteries by focusing on polymer science
Mike Zimmerman, CEO and founder of Ionic Materials, has this to say about his company: “Ionic will play a major role in the solution to the world’s energy problems.” That’s a pretty bold statement. But then again, Mike Zimmerman is a pretty bold man. An experienced polymer scientist, Zimmerman has worked on a number of… Read more »
BMW partners with Solid Power to develop solid-state batteries
Solid Power has grown rapidly since it was established in 2012 as a spin-out company from the University of Colorado. The battery developer recently moved into a new facility in Louisville, Colorado that will triple its footprint. Now the company has announced a partnership with the BMW Group to develop its solid-state batteries for EV… Read more »
MIT-led study suggests route to improving solid-state batteries
Replacing a liquid electrolyte with a solid electrolyte could offer major advantages for both safety and energy storage capacity, but so far, attempts to develop a practical solid-state cell have run into major obstacles. Liquid electrolytes can be flammable, and are also prone to the formation of dendrites -thin, fingerlike projections of metal that build… Read more »
FDK and Fujitsu develop novel cathode material for solid-state batteries
FDK and Fujitsu Laboratories have jointly developed lithium cobalt pyrophosphate (Li2CoP2O7) as a cathode material for solid-state lithium-ion batteries. The new material can operate at charge/discharge voltages of more than 5 V, which is beyond the limits of current lithium batteries. The energy of a battery is a function of its voltage and capacity, so an… Read more »
Solid state ion-conducting membrane could enable safer batteries
Researchers at the University of Maryland have developed a flexible, solid-state, ion-conducting membrane based on a 3D Li-ion conducting ceramic nanofiber network. In “Flexible, solid-state, ion-conducting membrane with 3D garnet nanofiber networks for lithium batteries,” published in the Proceeding of the National Academy of Sciences, the scientists describe a hybrid solid-state composite electrolyte in which… Read more »
Researchers use superionic conductors as electrolytes for solid-state batteries
Researchers at the Tokyo Institute of Technology, in collaboration with Toyota and two other research institutions, have designed and tested solid-state batteries using a novel type of solid electrolyte. In “High-power all-solid-state batteries using sulfide superionic conductors,” published in Nature Energy, Yuki Kato and team members explain the advantages of superionic materials as solid electrolytes….

New electrolyte for solid-state batteries combines polymer and glass
Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »
