Lithium iron phosphate (LFP) battery called Shenxing to start series production in late 2023.

The new battery will begin mass production by the end of 2023 and will be available to electric car makers in the first quarter of 2024.

Applicable to any type of vehicle, according to CATL, the battery features a new graphite anode, new electrolyte formulation, thinner and safer separator and better ion transport. The accumulator also has reduced heat generation and is equipped with a new advanced battery management system (BMS).

By the timeline, the first electric vehicle manufacturer to use the new battery will be Avatr, a joint venture of CATL and Changan with the participation of Huawei

This battery called Shenxing Superfast Charging Battery will allow a range of up to 700 km on one charge, depending on the electric vehicle. But the highlight is even the ultra-fast charging: it allows you to add up to 400 km of autonomy in just 10 minutes - it is the first LFP battery in the world that supports 4C level charging.


And talking about a deficiency of LFP batteries, which is the use in very cold environments, CATL states that it mitigated this problem with the battery being able to be charged from 0 to 80% in 30 minutes, even at -10°C.

The reason this particular LFP is able to better perform in the freezing cold is due to tweak in chemistry. This like rival Gotion new blade battery is a LFMP. Which apart from improving cold weather performances also improves the energy density by bumping the fully charged resting voltage of LFP from around 3.4v to 4v of LFMP for comparison NMC, NCA are 4.2v

This also means battery capacity is easier to calculate because it doesn't have the Flat voltage of LFP during discharge.

The disadvantage of LFMP is a nearly 50% drop in charge/ discharge cycles compared to best of the best version of LFP. But still vastly superior(atleast 2x better) compared to the best NMC/NCA cells and it also retains the superior safety properties of LFP.

Western cold countries now have no reason not to switch over to these.

This new CATL battery has a charge rate of 4C.
For comparison the current mass selling EV sold in India barely reach 0.7C charge rate.

But OLA electric which is a investor in Israeli start up StoreDot will likely have batteries with a high 6C charge rate when they build their battery cell plant.

If for example a Nexon Max had a 6C capable battery it would charge at 240kw speed or 7min to reach 80%, nearly 8 times faster then current battery.

CATL developed World's first hybrid battery with EV-like range.

CATL launched Freevoy Super Hybrid Battery, the world's first hybrid vehicle battery to achieve a pure electric range of over 400 kilometers and 4C superfast charging, heralding a new era for high-capacity EREV and PHEV batteries.

New Freevoy unit to be used in nearly 30 models as hybrid demand soars in China.



Designed for hybrid vehicles of EREVs and PHEVs, CATL's Freevoy frees drivers from the constant need to charge, a common drawback of existing hybrid vehicles, offering the convenience of one charge to power an entire week's commute. Additionally, it delivers impressive charging speeds, providing over 280 kilometers of range on 10 minutes of charging, effectively dispelling range anxiety for EREV and PHEV owners.

Chinese battery giant CATL launched its first battery product focused on extended-range hybrids at a time when this category of electrified cars is seeing the fastest growth in sales among all segments.
The battery, known as Freevoy, is the world's first hybrid battery with a range of over 400 km (249 miles), according to CATL's Gao Huan, chief technology officer of its electric vehicle business in China.
Freevoy was being used by various Chinese EV brands, including Li Auto, and would be installed in models made by industry giants, such as Geely and Chery.
Nearly 30 extended-range hybrid models will be equipped with the CATL Freevoy battery.

An extended-range hybrid, or EREV, has a larger battery pack than other hybrid cars and runs on electricity only, with its gasoline engine serving as a power bank to recharge the batteries when they run low.

More Chinese consumers favour EREVs as they offer longer driving range than EVs and can cost less than gasoline cars.

Sales of EREVs have more than doubled in the first nine months this year compared to the same period in 2023, with more than 10 new models launched by Chinese brands including Stellantis-backed Leapmotor and Li Auto this year.

The strong demand has prompted CATL to develop the battery for automakers in China and potentially overseas.

This Freevoy Super Hybrid Battery from CATL combines Lithium Ion and Sodium Ion cells in the battery pack.

The Sodium Ion helps the cold temperature performance, it can charge at -30 Celsius and can drive normally at -20 Celsius without range drop and can operate upto -40 Celsius with range drop. Lithium Ion battery will be dead at those temperatures.

CATL, which is based in Ningde, China, also said it had made more progress in the speed of charging main batteries. The company said its new system would allow an electric vehicle to be charged enough in five minutes to drive 520 kilometers, or 320 miles.

CATL also said it would start selling sodium-ion batteries, which can retain over 90 percent of their charge even at a temperature of 40 degrees below zero, for use in cars and trucks with internal combustion engines. The sodium batteries could be used by automakers to replace conventional lead-acid batteries, which go dead in very cold weather, and in some electric cars.

The biggest surprise by CATL was an announcement about auxiliary batteries for electric cars. The batteries would share space in the underbody of cars, where there is currently only one large battery.
The auxiliary battery would be the first commercially available electric vehicle battery that would not use graphite as one of its poles, CATL said.
Removing costly graphite will eventually make the batteries cheaper, after some initial costs, and will allow 60 percent more electricity to be squeezed in each cubic inch of the battery, said Gao Huan, CATL’s chief technology officer for electric cars in China.

New-gen electric car batteries promise 1500km range, 515km charge in five minutes.







China’s CATL – makers of electric car batteries for brands including Tesla, BMW and Hyundai – has revealed a new revolutionary rapid charging, long-range battery tech.

Revolutionary cheaper, rapid charging battery tech with up to 1500km range has been revealed by CATL, the world’s largest producer of lithium batteries and supplier to brands including Tesla, Polestar and Mercedes-Benz.

The new second-generation Shenxing batteries were unveiled at the official CATL Tech Day 2025 in Shanghai, China, with a game-changing rapid charging rate of 520km in five minutes, or 2.6km/second.

The CATL tech is twice as fast as arch-rival BYD’s 1 megawatt charging revealed last month capable of adding 400km in ten minutes – equating to 1.3km per second.

BYD’s latest tech was already twice as fast as the most rapid Tesla recharging rate, making CATL’s advances twice as fast again.

Both CATL and BYD’s latest advances make recharging a battery-electric vehicle take around the same time – or less – than filling a petrol- or diesel-powered car’s fuel tank.

They both bring major advances in eliminating ‘range anxiety’ for battery-electric vehicles.

There was no confirmation which vehicles – and from which brands – would use the new batteries first, with the new tech announced along with several other innovations at the CATL event.

The company estimates 2027-28 for its dual-battery tech offering up to 1500km range for production vehicles from a single charge – besting the 1000-1200km promise of solid-state batteries in development by brands including Honda, Toyota and Mercedes-Benz yet to be seen in showrooms.

The dual-battery – or auxiliary battery tech – uses two different batteries and won’t recharge as quickly as the standard Shenxing tech but are still capable of 30-80 per cent charges in 30 minutes.

A third innovation may further reduce costs, with CATL confirming it will begin manufacturing sodium batteries – instead of lithium – under the 'Naxtra' brand for FAW (First Auto Works) freight trucks from December 2025.

They may also be a cost-effective replacement for lead-acid batteries used in internal combustion-powered cars and lithium-batteries in hybrid vehicles.

The million dollar question is - at what charging speed and how many charging cycles before battery degrades to 80% of original capacity.

I would say still the solid state battery has an advantage when it comes to safety and probably the battery life too.
