Promising breakthrou­gh in battery technology

- Jonathan Tirone

The 94-year-old creator of the lithiumion battery has invented another breakthrou­gh storage device that’s capturing the attention of industry heavyweigh­ts.

“John Goodenough, inventor of the lithium battery, has developed the first all-solid-state battery cells,” Alphabet’s executive chair Eric Schmidt said via Twitter on Tuesday. Goodenough’s claim that his new battery cells have three times as much energy density as today’s lithium-ion batteries is “promising,” according to Google’s former CEO.

A new and more powerful generation of batteries may be made entirely from glass, according to the conclusion­s of Goodenough and his team of researcher­s published by the U.K. Royal Society of Chemistry. They store and transmit energy at temperatur­es lower than traditiona­l lithium-ion packs and can be made using globally abundant supplies of sodium.

The research could result in “a safe, low-cost, all-solid-state cell with a huge capacity giving a large energy density and a long cycle life suitable for powering an all-electric road vehicle or for storing electric power from wind or solar energy,” the researcher­s wrote in the peer-reviewed journal Energy & Environmen­tal Science.

Energy storage is seen as the missing link in the world’s transition to a zerocarbon economy. Batteries can fill power gaps from intermitte­nt solar and wind energy. Companies including Tesla and Volkswagen have set their sights on lithium-ion to usher in a new generation of plug-in vehicles.

The research conducted by Goodenough and his team, who worked from the University of Texas at Austin as well as at the University of Porto in Portugal, was driven by the “urgent” need to reduce fossil fuel consumptio­n and combat climate change.

The researcher­s are working on several patents and are seeking to collaborat­e with battery makers “to develop and test their new materials in electric vehicles and energy storage devices,” according to a statement by the University of Texas.

“The road from the lab to the factory is a long one,” said Julia Attwood, an analyst at Bloomberg New Energy Finance.

“Some technologi­es encounter significan­t difficulti­es when they attempt to scale up. It could be a while before we’re seeing these materials in electric vehicles or stationary storage.”

It took Goodenough about 11 years to see his lithium-ion breakthrou­ghs commercial­ized by Sony in 1991, according to a 2015 profile published by Quartz. The scientist began focusing on storage technologi­es at the Massachuse­tts Institute of Technology during the 1970s as a potential way of resolving the persistent oil crisis of the era, according to the article.

“We believe our discovery solves many of the problems that are inherent in today’s batteries,” Goodenough said.
