Analysis of CATL Shenxing Super Charging Battery: Charge for 10 minutes, range up to 400 kilometers

The trend of electric vehicles is developing rapidly worldwide, and as more and more people own electric vehicles, they are concerned that the time spent charging will increase in the future as it currently takes over an hour, which greatly consumes time cost. At this time, it's worth knowing about a revolutionary fast-charging battery product brought by CATL, the Shenxing supercharging battery, which achieves a super fast charging speed of "10 minutes of charging, 400 kilometers of range", and a range of over 700 kilometers greatly eases user's charging anxiety.

Highlights of Shenxing Super Charge Battery Technology

Shenxing super-charging battery is the world's first 4C super-charging lithium iron phosphate battery, (4C: represents charging speed, indicating that the battery is fully charged within 15 minutes, like 3C charging is full within 20 minutes, 2C charging is full within 30 minutes.). It is based on lithium iron phosphate batteries, and makes the following technological breakthroughs to achieve fast charging technology for batteries:

1. By increasing the speed of lithium ion detachment (in terms of cathode acceleration, Shenxing super charge battery adopts super electron network cathode technology, fully nanosized lithium iron phosphate cathode materials, and builds super electron network, which reduces the resistance of lithium ion detachment and makes the charging signal respond quickly).

2. Improve the efficiency of lithium ion adhesion (in terms of innovation of negative electrode materials, Shenxing super charge battery adopts CATL's newly developed second generation fast ion ring technology. It modifies the surface of graphite, increases the embedding channel of lithium ions and shortens the embedding distance, which builds a "highway" for ion conduction. At the same time, Shenxing super charging battery uses a multi-gradient layered electrode design, achieving the perfect balance of fast charging and endurance.).

3. Reduce the lithium-ion conduction resistance(CATL has developed a new ultra-high conductivity electrolyte formula to effectively reduce the viscosity of the electrolyte and significantly increase the conductivity. In addition, CATL has optimized the ultra-thin SEI film to further reduce conduction resistance.)

4. Improve lithium-ion liquid phase transmission rate(CATL also improves the high porosity and low tortuosity of the separator, thereby improving the lithium-ion liquid phase transmission rate.)

Advantages of Shenxing Supercharging Battery

1. Fast replenishment and mileage break the upper limit: Shenxing supercharged battery can not only achieve 400 kilometers of driving after charging for 10 minutes, but also on the basis of CTP3.0, CATL creatively proposes an integrated grouping technology to achieve high integration and high grouping efficiency, so that the Shenxing supercharged battery easily achieves a long range of more than 700 kilometers. It generally takes 5-10 minutes to refuel a family sedan, but it can run an average of 400-500km after a full refuel. The mileage limit of electrified vehicles using Shenxing supercharged batteries in the future can break through​​ 700km. It's known that the endurance of previous lithium iron phosphate batteries couldn't compete with nearly same capacity ternary lithium batteries, but with the arrival of Shenxing supercharged battery, this Fate may be broken.

2. In the past, the low temperature performance of LiFePO4 batteries was not good. The capacity drops quickly when the temperature is below 0 degree, and the cycling performance at low temperature is extremely poor, which affects the output performance and charging efficiency. However, CATL's ShenXing supercharging battery can completely improve this problem. At room temperature, the ShenXing supercharging battery can be charged to 80% SOC in 10 minutes. At the same time, CATL adopts core temperature control technology on the system platform, which can quickly heat up to the optimal working temperature range in low temperature environment. And it can achieve 30 minutes of charging to 80% even in a -10℃ low temperature environment, and the zero to hundred acceleration does not decrease in low temperature state of power loss.

3. No matter how strong the battery performance and charging efficiency are, safety is the top priority. CATL's ShenXing supercharging battery uses improved electrolyte and is equipped with a high safety coating separator, providing a "double insurance" for battery safety. In addition, CATL manages the overall temperature field through intelligent algorithms, creating a real-time fault detection system for daily battery safety protection.

So when and which car models will use this Shenxing super charger battery? According to the technical press conference, mainstream manufacturers such as CAHANGAN, CHERY, GAC, GEELY, GWM, and HUAWEI will deeply cooperate with CATL and install the new batteries on their respective brand models. The fastest in the first quarter of 2024, consumers will be able to purchase electric vehicles equipped with Shenxing supercharger batteries.

It is worth noting that CATL also mentioned its own zero-emission factory plan, because many people think that battery production companies are polluting, but Sichuan Times will become the world's first battery zero-carbon factory. It will achieve through electricity (energy saving technology to reduce energy consumption, import CFMS intelligent system, full water and electricity replacement), natural gas (improve boiler thermal efficiency, coating machine energy saving and consumption reduction, dehumidifier energy saving technology, zero carbon natural gas, efficient condensate water recovery system use), traffic (logistics transport electrification, travel electrification), others (comprehensive electrification, carbon trading offset other carbon emissions).

Summary: From 2017 to 2022, CATL power batteries were ranked first in global usage for six consecutive years. In the first half of 2023, CATL power batteries were also the first in global usage, with a market share of 36.8%, which can be described as the industry leader in the battery industry. From the first generation sodium-ion battery, Kirin battery, solid-state battery to the newly released Shenxing super charger battery, each product can bring breakthroughs for new energy vehicles. And today's Shenxing super charger battery, CATL through continuous optimization of technology, cost reduction, let Shenxing super charger battery become a standard product that every electric vehicle can use. It is no longer an option for high-end models, but a good thing for potential new energy vehicle owners in the future.
