CATL announced that its Shenxing, a 4C superfast charging LFP battery, can deliver 400 km (248 miles) of driving range with a 10-minute charge and a range of over 700 km (434 miles) on a single full charge. The company said Shenxing uses 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.

For graphite innovation, CATL said its 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.

CATL also developed a brand-new superconducting electrolyte formula, which it said 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.

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, the company said.

CATL developed an all-in-one grouping technology on top of integrating the internal crossbeam and end plates featured in its CTP 3.0 technology, achieving high integration and high grouping efficiency, enabling Shenxing to reach a range of over 700 km, the company added.

At room temperature, Shenxing can charge to 80% SOC in 10 minutes, according to the company. Meanwhile, CATL said it leverages cell temperature control technology on system platforms to rapidly ensure that cells heat up to the optimal operating temperature range, allowing a 0-80% charge in just 30 minutes at temperatures as low as -10°C.
