Lithium-Ion Battery Inventor Introduces New Technology for Fast-Charging, Noncombustible Batteries
USTIN, 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).
Today’s lithium-ion batteries use liquid electrolytes to transport the lithium ions between the anode (the negative side of the battery) and the cathode (the positive side of the battery). If a battery cell is charged too quickly, it can cause dendrites or “metal whiskers” to form and cross through the liquid electrolytes, causing a short circuit that can lead to explosions and fires. Instead of liquid electrolytes, the researchers rely on glass electrolytes that enable the use of an alkali-metal anode without the formation of dendrites.
The use of an alkali-metal anode (lithium, sodium or potassium) — which isn’t possible with conventional batteries — increases the energy density of a cathode and delivers a long cycle life. In experiments, the researchers’ cells have demonstrated more than 1,200 cycles with low cell resistance.
Additionally, because the solid-glass electrolytes can operate, or have high conductivity, at -20 degrees Celsius, this type of battery in a car could perform well in subzero degree weather. This is the first all-solid-state battery cell that can operate under 60 degree Celsius.
Braga began developing solid-glass electrolytes with colleagues while she was at the University of Porto in Portugal. About two years ago, she began collaborating with Goodenough and researcher Andrew J. Murchison at UT Austin. Braga said that Goodenough brought an understanding of the composition and properties of the solid-glass electrolytes that resulted in a new version of the electrolytes that is now patented through the UT Austin Office of Technology Commercialization.
The engineers’ glass electrolytes allow them to plate and strip alkali metals on both the cathode and the anode side without dendrites, which simplifies battery cell fabrication.
Another advantage is that the battery cells can be made from earth-friendly materials.
“The glass electrolytes allow for the substitution of low-cost sodium for lithium. Sodium is extracted from seawater that is widely available,” Braga said.
Goodenough and Braga are continuing to advance their battery-related research and are working on several patents. In the short term, they hope to work with battery makers to develop and test their new materials in electric vehicles and energy storage devices.
This research is supported by UT Austin, but there are no grants associated with this work. The UT Austin Office of Technology Commercialization is actively negotiating license agreements with multiple companies engaged in a variety of battery-related industry segments.

Tesla launches pickup truck. Specs are great but looks straight out of a cheap futuristic movie.

It looks absolutely horrible! Tesla should simply evolve its design of Model, S, X, 3, Y much like how Porsche evolves 911 design to SUV. More or less like this:

I'm looking at a 5-year horizon to buy an EV. I saw a Tesla 3 and was simply blown away on how elegant the design was.

As soon as they have triple capacity solid state batteries I will buy one. Be warned about Tesla, the cost of repairs is astronomical.
I have Model S for long time (in picture above charging at Hawthorne supercharger in 2013 where all Tesla are designed) Great car if your daily commute is less than 200 miles. Mine is 10 miles. Supercharger network in California is very strong so long commutes are possible. Nothing breaks down in these cars and car tells you if something needs to be fixed. There’s no need for regular service. Over the air update is indeed revolutionary- just like your iPhone the dashboard changes completely with new software. Interior could be more plush like BMW or Porsche but tesla technology is years ahead of any other car. Very fast as well and it is an absolute joy to drive- hard to go back to gas cars after driving one. No Porsche, BMW, Audi can beat this beast on the road for first 0-80 miles/hour.

This Electric HM Ambassador Rendered by DC2 Makes Us Wish it Was a Reality
Like wine, there are a few monikers in the automotive industry that only ages well. Among the top of them is the Hindustan Motors Ambassador. Even after the car stopped making an appearance on the street in the past decade or so, it was and is widely used among government officials as their official vehicle.
In a word, premium. The Ambassador was a mark of success. And with time it has only grown more favourite to enthusiasts around the country. And now to push the benchmark further, DC Design (now DC2) has digitally rendered their vision of the car in the modern-day. The car that you see above is a digital render of a concept that DC2 plans to build in the near future. But there's a catch to which we will come later.

this looks awesome...but it has to be rolled out .
this will be big if there is top class branding

Tesla has now started talking about Setting up a TERA factory in USA. One Tera factory will produce 1000 GWH of batteries, adequate for about 12 million cars per Annum.
This factory would be end of Crude Oil Era. I think peak oil will be hit in 2025, followed by decline from 2035.

My next motor vehicle will be an EV. I'm installing solar power on my new building for internal use and in the future for fast EV charging, by adding capacity.
But I will never ever buy Chinese EVs. No, no, no!

Needs vast improvement on the looks department. Maybe Hindustan can hire some Italian or German design companies or California-based design companies. Or it can set up a design company in Germany or California.This Electric HM Ambassador Rendered by DC2 Makes Us Wish it Was a Reality

Well!! it looks good on render..
Actually..I have seen a similar design almost 7 years back with Scissor doors and all from the same HM that time the stock price of HM was 25 or so..
then after almost many years ..I am seeing another render with electric version.
and now the scrip is prized at 4:00
lets see...how it plays out

Why do they keep flogging a dead horse. It;s dead.. forget and move on.... there are better cars avaialble .. for nostalgia, i will pickup a HM contessa than a ambassador....
and DC.. less said better...
