Offering a 400 km driving range with just a 10-minute charge
On August 16, CATL, a leading Chinese battery technology and critical minerals company, unveiled Shenxing, the world's inaugural 4C superfast charging LFP battery. This innovative battery boasts a remarkable capability, offering a 400 km driving range with just a 10-minute charge, along with a single full charge range exceeding 700 km. Shenxing is poised to effectively alleviate fast charging concerns for electric vehicle (EV) users, heralding an era of superfast EV charging.
CATL elaborated, stating, "As battery technology advances and EV battery performance improves significantly, the industry has achieved substantial driving ranges for EVs. However, fast charging anxiety remains a major hurdle for EV adoption. Leveraging our expertise in electrochemistry, CATL's comprehensive innovation in material, electrochemistry, and system structure has ingeniously achieved superfast charging, high energy density, and exceptional safety. Shenxing redefines the performance boundaries of LFP chemistry, driving innovation in the battery industry."
While initially targeted at the automotive sector, Shenxing's significance extends to mining fleets. CATL's Shenxing leverages super electronic network cathode technology and nano-crystallised LFP cathode material to establish a super-electronic network, streamlining lithium ion extraction and rapid response to charging signals.
For graphite innovation, CATL introduces second-generation fast ion ring technology to modify graphite surface properties, amplifying intercalation channels and shortening lithium ion intercalation distance, essentially creating an expressway for current conduction. An ingenious multi-gradient layered electrode design strikes the ideal balance between fast charging and extensive range.
Further breakthroughs include a fresh superconducting electrolyte formula that enhances electrolyte viscosity, translating into improved conductivity. The ultra-thin SEI film has been optimized to reduce lithium-ion movement resistance. By augmenting porosity and shortening transmission distance, CATL has effectively lowered lithium ion transmission resistance.
In addition to its 4C superfast charging feat, Shenxing attains remarkable driving range, swift charging across varying temperatures, and high safety through structural innovation and intelligent algorithms. CATL's groundbreaking all-in-one grouping technology, in conjunction with CTP 3.0 technology's integrated crossbeam and end plates, achieves high integration and efficiency, enabling Shenxing to reach a 700 km range, surpassing the limits of LFP chemistry performance.
At room temperature, Shenxing charges to 80% SOC in 10 minutes. Leveraging cell temperature control technology, CATL ensures optimal operating temperature range rapidly, enabling a 0-80% charge in 30 minutes even in -10°C, and uncompromised acceleration performance.
Shenxing's upgraded electrolyte and separator, featuring a secure coating, offer dual protection. Through intelligent algorithm-driven global temperature field regulation, CATL's real-time fault testing system guarantees safety amidst fast charging.
Speaking at the launch, Dr. Wu Kai, Chief Scientist of CATL, asserted, "The future of EV battery technology must remain at the global technology forefront while delivering economic benefits. As EV consumers transition from pioneers to regular users, we aim to make advanced technology accessible to all, enabling everyone to reap the rewards of innovation."
Leveraging its expertise in swift manufacturing, CATL boasts rapid technology transfer from lab to market, enabling Shenxing's mass production. Gao Huan, CTO of CATL's China E-car Business, projects mass production of Shenxing by end of 2023, with Shenxing-equipped EVs hitting the market in Q1 2024.
In conclusion, the launch of Shenxing marks a significant milestone in EV battery technology development, accelerating global e-mobility transition. CATL's commitment to democratizing advanced technologies is set to drive remarkable contributions to the global energy transition.
