CATL Launches Freevoy Super Hybrid Battery: Revolutionizing PHEV with 400km EV Range & 4C Ultra-Fast Charging

On October 24, CATL , the world’s largest EV battery manufacturer, unveiled a groundbreaking innovation in hybrid energy storage: the Freevoy Super Hybrid Battery. As the world’s first hybrid battery offering an all-electric range exceeding 400 kilometers (250 miles) and support for 4C ultra-fast charging, the Freevoy battery is set to redefine the plug-in hybrid (PHEV) and extended-range electric vehicle (EREV) markets.

With a new wave of PHEVs entering major global markets including China, CATL Freevoy battery technology makes switching to electric easier than ever—delivering an EV-like experience without compromising on performance, range, or convenience.

2. A New Era for Hybrid Batteries

The Freevoy Super Hybrid Battery directly addresses longstanding limitations of conventional hybrid systems, including short electric-only range, slow charging, and poor performance in cold climates. Freevoy empowers drivers with a week’s worth of typical commutes on a single charge, achieving up to 400 km (249 miles) of all-electric range—far surpassing most available PHEVs.

3. Breakthrough Chemistry: AB Architecture with Sodium-Ion and Lithium-Ion

What makes the Freevoy Super Hybrid so innovative is its unique hybrid chemistry. CATL’s proprietary AB architecture intelligently combines sodium-ion and lithium-ion cells within a single pack, optimizing performance across diverse conditions. This enables:

• Enhanced Cold-Weather Operation: The battery performs seamlessly down to -20°C (-4°F), with a 5% improvement in low-temperature range compared to conventional systems. It can discharge at -40°C and recharge at -30°C.

• Ultra-Fast Charging: Leveraging 4C ultra-rapid charging tech, the Freevoy battery can regain 280 km (174 miles) of range in just 10 minutes.

4. Engineering Excellence: Materials and Safety

The Freevoy utilizes a suite of advanced technologies to ensure reliability, speed, and safety:

• Fast Ion Conductor Coating on the cathode and specialized graphite and nano-coatings on the anode facilitate rapid lithium-ion movement.

• Multi-Gradient Electrode Design and high-conductivity electrolyte enhance charging efficiency and energy density.

• Safety Innovations: The second-generation zero-thermal-propagation technology and active isolation between smoke and high-voltage parts bring cell defect rates down to PPB (parts per billion) levels.

• Bidirectional Interaction: Supports vehicle-to-grid (V2G) capabilities and reverse power delivery.
