Tesla supplier CATL announces new MP3 battery with 430 miles of range

[DFW]

Shanghai Tesla
China now has built and is selling the Model Y with CATL MP3 battery modules.

What is MP3?

CATL MP3 are just a flat LFP battery module, same as Berlin Tesla's B.Y.D. blade flat LFP battery.
but
It seems CATL has improved their flat LFP configuration and LFP chemistry.

According to the article they used CLTC which is even more forgiving than WTLP

CLTC is 15-25% higher than WTLP
WTLP is 11% higher than EPA

I am guessing around 300 miles EPA

The current Chinese Tesla reports three hundred some miles.

Shenxing LFP fast charging battery



Accelerating extraction of lithium ions. Shenxing leverages the super electronic network cathode technology and fully nano-crystallized LFP cathode material to create a super-electronic network, which facilitates the extraction of lithium ions and the rapid response to charging signals.

On August 16, CATL launched Shenxing, the world’s first 4C superfast charging LFP battery, capable of delivering 400 km of driving range with a 10-minute charge as well as a range of over 700 km on a single full charge. Shenxing is expected to considerably alleviate fast charging anxiety for EV users, and opens up an era of EV superfast charging.

What 4C means every battery today charge at 1C or even less than 1C to prevent battery damage. 4C is a minimum 400% faster/powerful charging than any other EvBattery made today.
FYI
At home I charge my LiPo at 2C but I risk LiPo explosions and battery life degrade. 4C is a tremendous improvement in charging speed.

Improving lithium ion intercalation rate. For graphite innovation, CATL's latest second-generation fast ion ring technology is used to modify the properties of graphite surface, which increases intercalation channels and shortens the intercalation distance for lithium ions, creating an expressway for current conduction. Furthermore, a multi-gradient layered electrode design has been developed to strike a perfect balance between fast charging and long range.



Decreasing resistance of lithium-ion movement. CATL has developed a brand-new superconducting electrolyte formula, which effectively reduces the viscosity of the electrolyte, resulting in improved conductivity. In addition, CATL has improved the ultra-thin SEI film to reduce resistance of lithium-ion movement. Improving transmission rate of lithium ions: In terms of separator, CATL lowered the transmission resistance of lithium ions with high porosity and shortened average transmission distance.

Improve overall performance in charging speed, range and safety



In addition to achieving 4C superfast charging, Shenxing also achieves long driving range, fast charging over a wide range of temperatures and a high level of safety through structure innovation and leveraging intelligent algorithms.



Delivering a range of over 700 km. CATL has developed a trailblazing all-in-one grouping technology on top of the integration of the internal crossbeam and end plates featured in its CTP 3.0 technology, achieving high integration and high grouping efficiency. It enables Shenxing to reach a range of over 700 km, breaking the limits of the performance of LFP chemistry.



Charging as normal at low temperatures. At room temperature, Shenxing can charge to 80% SOC in 10 minutes. Meanwhile, CATL leverages cell temperature control technology on system platforms to ensure that cells heat up to the optimal operating temperature range rapidly, allowing a 0-80% charge in just 30 minutes in temperature as low as -10°C, and uncompromised 0-100 kph acceleration performance at low temperatures.



Safety First. The upgraded electrolyte and the separator with a highly safe coating are used to provide a dual protection of the Shenxing battery. By regulating the global temperature field inside the cells using intelligent algorithms, CATL has built a real-time fault testing system that can solve the problems brought about by fast refueling, enabling a high level of safety for the Shenxing battery.

Achieve mass production by the end of 2023, usher in the era of superfast charging



“The future of the EV battery technology must remain steadfastly anchored at the global technology frontier as well as the economic benefits,” said Dr. Wu Kai, Chief Scientist of CATL, speaking at the launch event. “As EV consumers shift from pioneering users to ordinary users, we should make advanced technology accessible for all and enable everyone to savor the fruits of innovation.”

Thanks to its strengths in extreme manufacturing, CATL has achieved the ability to rapidly transfer technology from lab to market, enabling rapid mass production of the Shenxing battery. According to Gao Huan, CTO of CATL’s China E-car Business, mass production of Shenxing will be achieved by the end of this year, and electric vehicles equipped with Shenxing will be available on the market in the first quarter of next year.

How can you claim range without the vehicle that battery will be in? Aerodynamics, weight, rolling resistance, how it is driven, where it is driven, etc… so many variables…

nC battery charging is very interesting.
I hope it works as expected and does not shorten the life of the battery.

Shenxing CATL 4C battery means to Tesla?
All old non Shenxing EvCars and EvTrucks become worth less!
Why?
Charge time is critical in EvCars and to reduce your charge time by 400% why would you ever want to by a old EvCar that are 1C charge.
Future
Is Tesla working on retro fittsing all its EvCars to Shenxing 4C.
Yes
But LFP need new charge software new structure new liquid cooling and new charging hardware.
and
It may not be worth it to retro fit all old or current Tesla to Shenxing 4C

So let me get this straight:

WLTP - Way Less than Predicted ?

CLTC - Consistently Lower than Calculated ?
