Contemporary Amperax Technology Co, Ltd (CATL) has announced a 4C super-fast-charging lithium-iron phosphate (LFP) battery. This battery is capable of delivering 400 km (249 miles) of driving range with a 10-minute charge and 700 km (435 miles) of range on a full charge.
Called the Shenxing, the new battery leverages CATL’s fully nano-crystalized LFT cathode material to create a “super electronic network” in the battery. This facilitates the extraction of lithium ions and charging signals rapid response. A new second-generation fast ion ring technology is used to modify the properties of the graphite surface, increasing intercalation channels and shortening the intercalation distance for lithium ions. Creating a sort of expressway for current conduction within the battery.
Several other innovations were created by CATL engineers to facilitate both long range and fast charging. A multi-gradient layered electrode design, new superconducting electrolyte formula, and a lowered transmission resistance contribute to that.
At room temperature, the Shenxing battery can charge to 80 percent SOC in 10 minutes. Various other temperature ranges change the charge time. A 0-80 percent charge can be achieved in 30 minutes at -10°C (14°F). Power delivery from the battery is only marginally affected by ambient temps.
The newly-developed electrolyte and the battery’s separator provide dual protection for regulating temperatures inside the battery. A real-time fault testing system solves problems brought about by fast refueling.
Shenxing will be available on the market in the first quarter of 2024. The company is also working on a sodium-ion battery with similar properties.
