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 »

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 »

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 »

Ionic Materials raises $65 million to develop its solid-state electrolyte

Ionic Materials has secured $65 million in a Series C financing round from investors in the battery manufacturing, consumer electronic and EV fields, who will be working with the company to speed the development of its solid polymer electrolyte battery material. “This funding round will allow us to add to our talented technical staff while… Read more »

A123 invests in solid-state battery tech firm Solid Power

A123 Systems has invested in Solid Power, a developer of solid-state battery technology. Solid Power’s tech combines a high-capacity cathode with a high-capacity lithium metal anode in combination with a high-ionic-conductivity solid separator. The battery materials are 100 percent inorganic, and possess no flammable or volatile components. Solid Power says its batteries provide two to… 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 »

New episode of Nova looks at the state of battery tech

As growing EV sales make the headlines, the general public is becoming more aware of the batteries they carry around in their pockets and laptop cases. A recent episode of PBS’s Nova, “Search for the Super Battery,” offers a digestible summary of some of the advances happening in the battery field. In an attempt to… 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 »
