CATL, a leading manufacturer of lithium-ion batteries, has launched Shenxing, the world’s first 4C superfast charging LFP battery. This battery is capable of delivering 400 km of driving range with a 10-minute charge and has a range of over 700 km on a single full charge. Shenxing is expected to considerably alleviate fast charging anxiety for EV users and open up an era of EV superfast charging.
Key Features of Shenxing
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.
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 surfaces, 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 that effectively reduces the viscosity of the electrolyte, resulting in improved conductivity. In addition, CATL has improved the ultra-thin SEI film to reduce the 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 the average transmission distance. In addition to achieving 4C superfast charging, Shenxing also achieves a 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 temperatures 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.
With 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.
