CATL’s LFP Battery Pack Achieves 1000km Range Milestone

Chinese battery giant CATL has made a significant breakthrough in the electric vehicle industry with the development of a fast charging battery pack that addresses range anxiety concerns. The new Shenxing PLUS battery pack, powered by CATL's lithium iron phosphate (LFP) batteries, boasts an impressive range of 1000 kilometers, providing users with a super-long range driving experience.

The innovative technology allows electric vehicles equipped with the Shenxing PLUS battery pack to travel long distances without the need for frequent recharging. According to CATL, the battery pack's capabilities enable a trip from Beijing to Nanjing without requiring a recharge along the way, making it ideal for both urban commuting and inter-provincial travel.

The 1000-km range achieved by the Shenxing PLUS battery pack is the result of a series of enhancements, including a unique cell to pack architecture. CATL has utilized granular gradation technology in the cathode of the LFP battery cell to optimize nanoparticle positioning and achieve ultra-high compact density.

In addition, a proprietary 3D honeycomb-shaped material has been incorporated into the anode, increasing energy density and effectively managing volume expansion during charge and discharge cycles. The single-piece casing design, a first in the industry, maximizes internal space utilization, allowing for higher energy density levels.

At the system level, the Shenxing PLUS battery pack features a topological structure optimized with module-free CTP 3.0 technology, enhancing packing efficiency by 7%. This optimization has pushed the battery system's overall energy density to over 200 Wh/kg for the first time, reaching an impressive 205 Wh/kg and making ranges exceeding 1000 kilometers a reality.

Moreover, the 4C fast charging capability of the battery pack enables a 600-km range to be achieved in just 10 minutes of charging, equivalent to one kilometer per second. This remarkable feat was made possible through the implementation of fast lithium-ion conductive coating, the addition of transition metal elements, and new nanometer encapsulation for improved energy transmission efficiency.

CATL has also enhanced the overcurrent area and capacity of the terminals in the battery system to facilitate rapid heat dissipation during high-current charging. Furthermore, the development of a new AI polarization model for the battery management system (BMS) core algorithms allows for real-time prediction and control of charging current, enabling faster and more intelligent energy replenishment.

With these groundbreaking advancements, CATL is setting new standards in the electric vehicle battery industry, paving the way for more efficient and reliable long-range electric vehicles. For more information, visit www.catl.com.
