94-year-old inventor of li-ion battery unveils solid-state battery breakthrough

“John Goodenough, who is credited as the co-inventor of the li-ion battery cell, and his team at the Cockrell School of Engineering have released their findings of what is being described as a ‘breakthrough’ for solid-state batteries,” Fred Lambert reports for Electrek.

“Solid-state batteries are thought to be a lot safer than common li-ion cells and could have more potential for higher energy density, but we have yet to see a company capable of producing it in large-scale and at an attractive price point,” Lambert reports. “In collaboration with senior research fellow Maria Helena Braga, the 94-year-old scientist published a recent paper in the journal Energy & Environmental Science that claims to solve some of those problems.”

“They are making impressive claims about the prototype cells that they produced with this new technology,” Lambert reports. “They say that it enables ‘at least three times as much energy density,’ demonstrated ‘more than 1,200 cycles with low cell resistance,’ and can operate ‘from -20 degrees Celsius to under 60 degree Celsius.'”

MacDailyNews Take: Usually, “battery breakthroughs” can be dismissed as hyperbole, but with scientist of Goodenough’s pedigree, not so fast! This sounds like more than “good enough,” indeed!


  1. As an expert in the area, let me say it is a travesty that Goodenough has not yet won the Nobel prize. Particularly given his age and the constraint that laureates must be living. In my book, this man should have won years ago.

    Besides the energy density, these would be non-combustible batteries that, yes, you could use in laptops.

    However, the use of metallic sodium as an anode is hinky – won’t play nice with water. Will take some serious engineering to make these play nice in a car or laptop. Cars in particular – a high speed crash exposing metallic sodium to ambient humidity is bad; pouring water on a smoldering sodium anode battery will be a zillion times worse. Lots of youtube videos out there to demonstrate that point. Will have to be lots and lots and lots of engineering and field testing.

    However, for stationary power sources or grid energy storage – game on! Just deactivate the sprinkler system overhead, heh.

      1. You should do something about your ignorance. Nobel prize committees (one for each prize) are independent of each other. Chemists do not nominate and pick Peace prize winners. Here’s the Chemistry committee: https://www.nobelprize.org/nobel_prizes/chemistry/prize_awarder/committee.html They solicit from the following: https://www.nobelprize.org/nomination/chemistry/index.html

        Moreover, while the Royal Swedish Academy of Sciences administers the prizes for Chemistry, Physics, Medicine, and Literature, it is the **NORWEGIAN** Nobel committee which is appointed by the NORWEGIAN parliament that decides the Peace prize. And if you care to review, the eligible nominators are listed here: https://www.nobelpeaceprize.org/Nomination/Criteria-for-nominators No scientists there. So not even my two friends and multiple colleagues who have won a science prize can nominate someone for Peace.

        Congratulations for demonstrating, in the words of Forest Gump, “Stupid is as stupid does”.
