Contemporary Amperex Technology Co. Limited (CATL), the world’s largest electric vehicle battery manufacturer, has officially commenced mass production of its fifth-generation lithium iron phosphate (LFP) batteries, marking a significant leap forward in battery technology. Announced in November 2025, this new generation promises substantial improvements in energy density, charging speed, and cycle life, spearheaded by the “Shenxing PLUS” model. The advancement aims to address key barriers to electric vehicle adoption, including range anxiety and charging convenience.
Unprecedented Energy Density and Range
The Shenxing PLUS battery, a flagship product of CATL’s fifth-generation LFP platform, boasts an impressive energy density of 205 Wh/kg. This breakthrough pushes LFP chemistry beyond the 200 Wh/kg threshold for the first time, directly challenging the energy density typically associated with higher-cost nickel-manganese-cobalt (NMC) batteries. This enhanced density allows for an extended driving range exceeding 1,000 kilometers (621 miles) on a single full charge, enabling vehicles to undertake long journeys without needing a recharge.
The proprietary granular gradation technology in the cathode and a 3D honeycomb-shaped anode material contribute to this ultra-high compact density and efficient volume control. Furthermore, a pioneering single-piece casing and an optimized topological structure with module-free CTP 3.0 technology increase packing efficiency by 7%, maximizing internal space utilization and overall energy capacity.
Breakthrough Charging Capabilities
One of the most significant features of CATL’s new LFP batteries is their ultra-fast charging capability. The fifth-generation LFP system supports a peak charging power of 830 kW, a figure typically linked to premium lithium chemistries. This allows for rapid replenishment of range, with the Shenxing PLUS capable of adding 600 kilometers of range in just 10 minutes of charging. Under ideal conditions, the general 5th-gen LFP battery can add up to 478 km (WLTP) of range in the same timeframe. Even in extreme cold, such as minus 20 degrees Celsius, drivers can expect approximately 410 km in 20 minutes, effectively closing the gap between cost-friendly LFP packs and high-output ternary batteries.
This rapid charging is facilitated by several advanced technologies, including a fast lithium-ion conductive coating, the addition of transition metal elements, and an AI polarization model that predicts and controls charging current in real-time. These innovations enhance the movement of ions and ensure rapid heat dissipation during high-current charging, maintaining safety and efficiency.
Enhanced Longevity and Safety
Beyond speed and range, the fifth-generation LFP batteries offer a significantly longer operational life. Real-world testing demonstrates over 91% capacity retention after 200,000 km of use. CATL estimates an impressive service life of up to 12 years or one million kilometers, which is expected to considerably lower the total ownership cost for electric vehicle fleets and frequent fast-charging EV users.
A key safety and efficiency feature is the new wave cell architecture, which increases the thermal contact surface and improves cooling during high-power charging sessions. This enhanced heat flow contributes to safer and more efficient charging, while maintaining CATL’s robust safety standards. The battery has also secured full certification, including type, production, airworthiness, and operation approvals, making it suitable for aviation and maritime use.
Broader Market Impact and Future Outlook
CATL’s decision to begin mass production of its fifth-generation LFP batteries signals strong confidence in their durability and technical maturity. With LFP prices continuing to decline through 2025, this advancement positions the chemistry as an even more attractive option for affordable EVs and the electrification of commercial fleets.
As the world’s largest battery manufacturer, holding a 36.6% global market share from January through September 2025, CATL continues to innovate across various chemistries. Alongside the new LFP batteries, the company is also advancing its ternary lithium solutions and has introduced the Naxtra sodium-ion battery, designed to reduce dependence on lithium and improve low-temperature performance. Furthermore, CATL’s research into all-solid-state batteries is among the most advanced globally, with large-scale commercialization targeted for approximately 2030, indicating a long-term vision for battery technology. The new LFP batteries and the Shenxing PLUS are set to underpin a new era of electric mobility, making EVs more accessible, practical, and efficient for a wider range of applications and consumers.
