At its first-ever Super Tech Day, Contemporary Amperex Technology Co., Limited (CATL) introduced three revolutionary EV battery products: the Freevoy Dual-Power Battery, Naxtra (the world’s first mass-produced sodium-ion battery), and the second-generation Shenxing Superfast Charging Battery, along with an integrated 24V start/stop Naxtra battery for heavy-duty trucks. These innovations break technological barriers and herald the dawn of the “Multi-Power Era” in the industry.
The Freevoy Dual-Power Battery features a groundbreaking cross-chemistry system that surpasses the limitations of traditional single-technology solutions, offering customized options to meet user demands. Naxtra, the first mass-produced sodium-ion battery, addresses resource limitations and solidifies the foundation for the new energy sector. The second-generation Shenxing Superfast Charging Battery, with a peak 12C charging rate, sets a new global benchmark for ultra-fast charging technology.
Naxtra Battery: Breaking Performance Limits, Powering the Future of Energy
CATL’s Naxtra Battery marks a breakthrough in sodium-ion technology, achieving mass production for the first time. Offering improved safety and reduced lithium dependence, it advances energy freedom. The Naxtra line includes passenger EV and 24V heavy-duty truck batteries, both operating reliably from -40°C to +70°C, with the EV version retaining 90% power even at -40°C and low charge levels.
CATL’s Naxtra passenger EV Battery delivers an industry-leading energy density of 175Wh/kg—on par with LFP batteries—enabling a range of 500 km and over 10,000 charge cycles. Its design emphasizes intrinsic safety by eliminating combustion risks at the material level, reducing maintenance costs and enhancing reliability.
The Naxtra 24V Heavy-Duty Truck Battery offers over 8 years of service life, slashing lifecycle costs by 61% compared to lead-acid batteries. It supports deep discharge, starts reliably at -40°C, and can function after a year of inactivity. These features make it a more efficient and eco-friendly alternative, moving the commercial sector toward a lead-free future.
CATL’s sodium-ion breakthroughs address the limitations of battery performance in extremely cold environments, unlocking full-scenario applications. These advancements also led to the development of the Freevoy Dual-Power Battery, designed to flexibly meet diverse user needs through cross-chemistry innovation.
Freevoy Dual-Power Battery: Ushering in the Multi-Power Era of Energy Freedom
CATL’s Freevoy Dual-Power Battery features a dual-power architecture with two independent energy zones, enabling five key dual functions—high/low voltage, structure, thermal management, and safety protection. Combined with advanced software, it ensures stable, reliable power for future L3 and L4 autonomous vehicles, enhancing performance, continuity, and safety.
CATL’s self-forming anode technology boosts battery energy density by 60% volumetrically and 50% gravimetrically, enabling more power and longer range in the same space. It’s compatible with multiple materials and can exceed 1000Wh/L when paired with NCM systems.
CATL’s dual-electric range extension technology in the Freevoy Dual-Power Battery intelligently adjusts energy use based on driving status and habits. It combines different chemistries for daily use and high-energy self-forming anode tech for long-distance travel, maximizing efficiency and range.
CATL unveiled three dual-power battery solutions using different chemical systems:
- NCM-LFP and NCM-NCM Dual-Power Batteries: These configurations combine NCM batteries with either LFP or NCM batteries using self-forming anodes. The NCM system in the main energy zone achieves a 12C peak charging rate and over 1MW of output power, maintaining more than 600kW even at 20% SOC. The upgraded NCM-NCM version supports over 180 kWh of capacity, enabling sedans with a 3-meter wheelbase to surpass a 1,500 km all-electric range.
- Sodium-LFP Dual-Power Battery: This combines Naxtra sodium-ion cells with an LFP battery featuring self-forming anode technology. It leverages sodium’s superior cold-weather performance, delivering strong range and reliable functionality in low temperatures.
- LFP-LFP Dual-Power Battery: Pairing the second-gen Shenxing Superfast Charging Battery with an LFP battery using self-forming anodes, this system enables up to 1,000 km of pure electric range in sedans with a 3-meter wheelbase, while reducing per-kilometer commuting costs to just 0.1 yuan.
CATL’s Freevoy Dual-Power EV Battery enables different chemical systems to work together, overcoming the limitations of single chemistries and allowing for customized performance across various cost tiers and use cases. This multi-power approach extends beyond EVs to buses, trucks, aircraft, ships, and industrial applications, advancing renewable energy adoption and paving the way for future technologies like solid-state batteries.
Second-Generation Shenxing Superfast Charging Battery: Setting New Global Records
CATL’s second-gen Shenxing Superfast Charging Battery sets new benchmarks with an 800 km range and a 12C peak charging rate. Delivering 2.5 km of range per second, it features 1.3 MW peak power. Even at -10°C, it charges from 5% to 80% in just 15 minutes—twice as fast as current top industry standards.
Additionally, CATL’s second-generation Shenxing Superfast Charging Battery delivers 830kW of power even at low charge and in -10°C, meeting the power demands for 0-100km/h acceleration.
Multi-power batteries shift from being “parameter-driven” to “demand-driven.” CATL is pushing technological boundaries, leading the transition to a user-centric multi-power era in the new energy industry.
