CATL, the world’s largest manufacturer of EV batteries and a major supplier for Tesla, has introduced a revolutionary new lithium iron phosphate (LFP) battery that boasts fast charging capabilities. 

Named Shenxing, this new EV battery can provide an impressive 400 km (248 miles) of range with just a 10-minute charge.

During an online briefing on August 16, CATL revealed that Shenxing is the first battery of its kind to support 4C super fast charging. This enables Shenxing to charge at a current of 12A above the diffusion limiting current.

Gao Han, the chief technology officer of CATL’s E-Car Business, expressed hopes that Shenxing will eventually become a widely available standard product for all EVs. In its pursuit of superior technology and cost reduction, CATL has managed to achieve a perfect combination of super fast charging, high energy density, and top-notch safety with the Shenxing battery.

Using proprietary technology, CATL has incorporated various advancements into this fast-charging LFP battery. These advancements include accelerated lithium ion extraction, as well as an improved lithium-ion intercalation rate. 

Other innovations include a multi-gradient layered electrode design, a new superconducting electrolyte formula, and an ultrathin separator. 

Notably, the Shenxing LFP battery can handle fast charging even in low temperatures. At 14℉, it can charge from zero to 80 percent in just 30 minutes. 

The Shenxing battery also uses computer algorithms to regulate temperatures inside the cells, maximizing safety.

CATL plans to commence mass production of the Shenxing battery in China by the end of the year. The first EV models featuring Shenxing batteries are expected to be launched in the first quarter of 2024.

Compared to other lithium-ion batteries, LFP batteries offer cost advantages and increased durability. Traditionally, they have struggled with lower energy density and performance degradation in colder conditions. 

However, CATL claims to have overcome these limitations. The company states that the Shenxing battery strikes a perfect balance between long range and convenient refueling.

Amidst a price war and a slowdown in auto sales this year, CATL has encountered challenges from weakening demand and cost reduction pressure. Nonetheless, CATL remains a key supplier for Tesla, the world’s largest EV maker.
