CATL reveals Shenxing Plus LFP battery with 600+ mile range

The Shenxing Plus LFP battery has approx. 621 miles of range and can achieve approx. 373 miles of range with charges lasting 10 minutes.

At Auto China 2024, CATL unveiled Shenxing Plus—an LFP battery that achieves a range above 1,000 km. (approx. 621 miles) with 4C superfast charging. CATL said the cathode of Shenxing Plus is made with a granular gradation technology, which places every nanometer particle in a position to achieve ultra-high compact density. The company adds its proprietary 3D honeycomb-shaped material to the anode, which it said boosts the energy density while effectively controlling the volume expansion during charge and discharge cycles. According to CATL, the single-piece casing also optimizes the internal space utilization, allowing the Shenxing Plus cells to reach a high energy density level. At the system level, the company said its Shenxing Plus battery pack has a topological structure optimized on top of module-free CTP 3.0 technology, enhancing the packing efficiency by 7%. The Shenxing battery system’s energy density surpasses the 200 Wh/kg threshold for the first time, reaching 205 Wh/kg, making ranges over 1,000 kilometers a reality.

Aside from offering long-range, CATL said the Shenxing Plus also charges fast. It can deliver a 600-km (approx. 373 miles) range in just 10 minutes of charging.

To achieve quick charging speed, CATL said the Shenxing Plus applies technologies including fast lithium-ion conductive coating, the addition of transition metal elements, and new nanometer encapsulation, rendering smoother and more efficient energy transmission between cathode and anode materials. CATL expanded the overcurrent area and capacity of the terminals in the battery system to dissipate heat during high-current charging. In terms of BMS core algorithms, CATL said its newly-developed AI polarization model can predict and control the charging current in real-time, enabling faster and smarter energy replenishment.

CATL said it has also initiated the construction of the Shenxing Superfast Charging Network to build the largest superfast charging service platform in China. CATL is collaborating with partners like Star Charge, YKC and Shudao New Energy to provide a convinient experience for more owners of cars powered by Shenxing superfast charging batteries, the company said.

CATL plans to launch the industry’s first Shenxing superfast charging vehicle owners club, operating in over 600 service outlets covering 271 prefecture-level cities in 31 provincial-level regions. It will provide Shenxing vehicle owners with roadside rescue, battery inspection and maintenance, and other services.
