Lithium-Ion Battery Inventor Introduces New Technology for Fast-Charging, Noncombustible Batteries
AUSTIN, Texas — A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.
Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a
low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge. The engineers describe their new technology in a recent paper published in the journal
Energy & Environmental Science.
“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries,” Goodenough said.
The researchers demonstrated that their new battery cells have at least three times as much energy density as today’s lithium-ion batteries. A battery cell’s energy density gives an electric vehicle its driving range, so a higher energy density means that a car can drive more miles between charges. The UT Austin battery formulation also allows for a greater number of charging and discharging cycles, which equates to longer-lasting batteries, as well as a faster rate of recharge (minutes rather than hours).
All of that, and low cost. If this can be mass manufactured, the ICE is dead.
Germany and Norway leading the way.
Now you add what Tesla is doing with home solar and energy storage, and we are going to see a paradigm shift in how we generate and distribute electricity in the 21st Century.
How the hell is any of that a "paradigm shift" in energy
generation (???) or
distribution.
Perhaps in distribution if you ship electricity in cartons full of batteries by UPS instead of a power line grid.
Next thing this innovation, the only difference is a glass membrane separating the 2 components that give you the emf between Li and whatever the other one would be...and that could be at best Fluorine then you get a -5.91 Volt potential. That`s as good as it possibly can get unless there is some Kryptonyte or Unobtanium we could mine from some planet with highly advanced aliens.
Nowhere in that publication is anything that shows a 3 times higher energy density. 3 times higher than what? A lead acid car battery perhaps.
The Voltage on the Y axis is what you would get with a Sodium electrode referenced against Hydrogen which is used as a standard for emf comparisons...and that should be - 2.71 Volts.
With Lithium against a standard Hydrogen electrode you should get - 3.04 Volts
I don`t see any of that in that diagram. 2.68 Volts is the max V potential and that`s not 3 times higher than anything we have so far.
So the only avenue which remains open to pack 3 times the energy if it was not done by Volts are ampere hours. And he does not show you a diagram for the discharge? Why not?
Because he can`t show that it has 3 times the amp hours.
So instead he claims he can pack 3 times the amount of active substance per volume to "give you" 3 times as much energy. He says he can do that because the glass membrane bars dendrites bridging the 2 electrodes causing a short.
This "paradigm shift" is nothing but the hot air that gets published in today`s publish or perish academic environment. Not even the glass membrane mentioned is a technical innovation. Every electrode used in labs to measure specific ions use glass membranes.
The other "paradigm shift" is going a step backwards from Li batteries to the old and outdated Sodium based batteries and the publishers of this no-news paper "informs" us that sea water contains lots of Sodium and that it is cheaper than Lithium.
No wonder that the only people who are impressed by this and call it a "paradigm shift" in science and technology are those who have no clue.
