Battery technologies for a fast charging and changing world

[JohnDe]

but that interchangeability might move closer , maybe overlap in time

Anything is possible, especially in the lower cost range for EVs.

The thing with capacitors and batteries is the energy density, one is good for hybrids and the other for full EV systems.

Will that change in the future? Only if capacitor technology surpasses battery technology, in regard to energy density, and can hold the equivalent energy in a similar size package for an equal or lower cost.

With the way miners and manufacturers are producing battery materials and technology, it will take something great to put capacitors in front for EV manufacturers to drop their battery packs.

But stranger things have happened; Beta vs VHS comes to mind.

Energy density per kg or per weight?
A mostly not discussed is the serious problem of battery weight.
Having truck like weight for a car carrying 1 or 2 persons is a nightmare for the infrastructure, safety and overall kwh per km.
We once were trying to reduce ice consumption with lightening vehicles: aluminium, alloy, plastics...
I do believe capacitors are much lighter by nature
I believe but might be wr

Capacitors store less energy per weight compared to a battery. However, if you compare supercapacitors to a battery then it is a closer match, except for the cost. A supercapacitor is not a cheap item to build., and then there is the problem of holding a charge long term. From memory, I think they lose about 40% of their charge after a month.

Ok, was wrong in energy density.
Yes not yet ready and as mentioned before different purpose: perfect for regen braking etc
Not so much to be plugged daily in the garage.
The weight issue remains..
Not critical for my home batteries but for an EV
Maybe other battery technology will sort this out

CATL has just moved the goal posts on speed of EV charging. Radically.

CATL unveils new EV battery that charges as fast as pumping gas​

China’s Contemporary Amperex Technology Co., Limited (CATL) has unveiled its latest battery cell technologies, which charge as quickly as filling up a gas tank while potentially lowering costs without compromise.

CATL has quickly become the world’s largest battery manufacturer by a wide margin. It is one of, if not the biggest, force for advancing electric transportation.

A big part of CATL’s success is due to its advancements in lithium-iron phosphate battery cells, also known as LFP. LFP cells are cheaper than nickel-rich batteries, but they used to have much lower energy density.
The Chinese battery manufacturers managed to close the gap somewhat while maintaining lower costs, resulting in LFP cells becoming popular for entry-level EVs.

Now, CATL is looking to do the same with sodium-ion batteries.

Like LFP cells, sodium-ion battery cells have the potential to be cheaper than more common Li-ion cells, but they also offer potential for superior performance, particularly in terms of faster charging and longer lifecycles.

CATL has unveiled today Naxtra, its new sodium-ion battery cells, and it claimed some truly impressive specs.
The new cell reportedly achieves an energy density of 175 Wh per kg (385 Wh per lb), on par with the higher-end of LFP battery cells.
The new cells also offer potential for significant safety improvements.

CATL shared several intense stress tests, including drilling into a cell and even cutting it in half without any thermal event:


On top of the new Naxtra cell, CATL has also unveiled its next-gen Shenxing LFP battery cells.

Its charge rate is truly impressive. CATL shared several examples of cars charging at around 1,000 kW and maintaining over 500 kW at over 50% state of charge:


The new cell is being described as capable of adding 300 miles (482 km) of range in about 5 minutes – depending on the EV model.

So, we can assume that the technical issue with charging being slower than gas filling is solved. Next is to get the infrastructure and the vehicles available with this technology at a price point that consumers are willing to pay. I see that happening in 2-3 years. Sadly, US might be left outside looking in.

That’s virtually as quick as filling up a tank of gas.
CATL says that the Shenxing will be in 67 electric vehicle models by the end of the year.

@basilio Though not the owner of an EV or hybrid as yet I find this latest technology mind blowing.
No doubt when we decide to upgrade to an electric vehicle the technology will have gone forward again in leaps and bounds.
For the time being out petrol AWD will suffice as a great tax claim for the farm.

World's first 9 MWh energy storage system by CATL can power a house for 5 years with zero degradation

CATL's new Tener Stack energy storage system breakthrough can supply electricity from renewables to the average home for up to six years, in the first five of which it will undergo zero capacity degradation. It can also charge 150 electric vehicles before its batteries run out.

The world’s largest battery maker is Contemporary Amperex Technology Company, or CATL. Since its founding in 2011, the company has enjoyed meteoric growth partly thanks to China’s state-sponsored support of renewable energy.

The company’s products power more than one-third of the world’s electric vehicles and it has branched out into storage systems for energy grids.

Last week, CATL’s plans for global domination of cutting-edge batteries were given a major boost with the world’s largest share offering so far this year. CATL raised $HK35.7 billion ($7 billion) in a secondary listing in Hong Kong. Shares surged as much as 18 per cent on Tuesday as investors poured into one of China’s most strategically important companies.

CATL says it plans to use the proceeds of the listing to fund its international expansion plans.

That is a seriously clever commercial system. Very well thought out. Not to mention a 20year battery warranty.

Came across another excellent super quick battery charging technology that is being commercially produced. Not expensive either. And it is not in China !

Excellent background story and explanation of how they developed the technology.
( I came across this company while looking at Talga information. Nyobolt will be Talgas first (small) anode off take customer)

Nyobolt: Six minutes to charge an electric car​

Nyobolt, a British company, has built a battery able to charge from 10 to 80 per cent in under five minutes, twice the speed of the fastest-charging vehicles on the road. It's an innovation that ends the range debate for good, and is set to change the way the world thinks about electric cars
To demonstrate the technology and its readiness for production, Nyobolt developed its own fully functioning concept car, the Nyobolt EV with a proprietary 35kWh battery. And yes, the public demo proved the EV demonstrator charges, using a 350Kw charger from zero to 80 per cent in four minutes thirty seven seconds, and to full in six minutes.

So how much will it cost me to install a fast charger to accommodate that charging rate?

From Evolution Australia for a AURIGA DC Fast Charger 30Kw approx. $14,995.00
The mind boggles at what a 350kW system will cost and that's without even thinking about the area required for a solar panel system to charge it.

On the other side of batter technology.
How to quickly, cheaply and environmentally safely recover the resources from spebt batteries.

Excellent overview of current processes and the next you beaut option

Iondrive is mentioned in the above video. It is an Adelaide based company. ASX code ION and its share price went from 0.015 on 19 May 25 to 0.036 in last few days. Anyone tracking ION?

Also in Basils vid; Redwood Materials... a recent Sandy Munroe walk though of Redwoods Reno facility with J B Straubel doing a lot of the talking is worth the time; not hard to find if you look.
Industrial scale recycling with dynamic use of prior to end of life batteries; enough to operate the entire recycling installation off grid and still power an operating on site Data Centre.... And only going to get bigger, much bigger. One mans trash, as they say.

I'd go as far as hazarding a guess at a Redwood facility not far from the slated Tesla battery plant in SA.
