CATL Unveils Freevoy Battery: 400-Wh/kg with 1,000km Range
CATL's new Freevoy battery achieves 400 Wh/kg energy density — a 50% jump over current generation — enabling 1,000 km (621-mile) EV range. Commercial samples go to automakers in 2026.
CATL, the world’s largest EV battery manufacturer, unveiled its Freevoy battery cell at a press event in Shenzhen on October 29, 2025. The cell achieves an energy density of 400 Wh/kg — a significant step forward from current-generation lithium-ion cells that typically max out at 250-270 Wh/kg — enabling over 1,000 km (621 miles) of range in a properly sized pack.
What Makes Freevoy Different
Freevoy uses a hybrid lithium-manganese iron phosphate (LMFP) chemistry with a new cathode material that CATL developed in partnership with a consortium of Chinese research institutions. The anode uses a silicon-carbon composite with a proprietary coating that suppresses expansion during charging cycles.
The key breakthrough is energy density, not the chemistry category itself. LMFP isn’t new — CATL and BYD have both used LFP (lithium iron phosphate) chemistries for years. What Freevoy achieves is getting LMFP to perform like higher-nickel chemistries in energy density terms while retaining LFP’s advantages in thermal stability and lifespan.
Specifications
- Energy Density: 400 Wh/kg (cell level)
- Gravimetric Energy: 400 Wh/kg — for context, current Tesla 4680 cells are ~250 Wh/kg
- Cycle Life: CATL claims 3,000 cycles to 80% capacity
- Charging Rate: 5C peak charge rate (enabling 0-80% in under 10 minutes)
- Operating Temperature: -30°C to 60°C without significant performance degradation
The 5C charging rate is particularly noteworthy — if CATL’s claims hold in production vehicles, it would make charging a 1,000 km-range EV in under 15 minutes a reality rather than a spec sheet fantasy.
Timeline and Availability
CATL says Freevoy is entering commercial sample production in Q1 2026, with volume production targeted for Q3 2026. The first automaker announced as a customer is NIO, which will use Freevoy cells in its 2027 150 kWh battery pack for the ET7 and ES8.
The premium pricing implied by the technology means the first applications will be in high-end vehicles. CATL expects Freevoy to reach cost parity with current high-nickel chemistries by 2028, enabling broader adoption in the mid-2028+ timeframe.
Industry Impact
CATL’s announcement is the latest salvo in the global battery arms race. competing with BYD’s Blade Battery refinements, Samsung SDI’s solid-state-adjacent plans, and QuantumScape’s solid-state program. The 400 Wh/kg figure puts CATL ahead of schedule on its own technology roadmap and close to the energy density threshold that solid-state cells are expected to achieve.
Whether Freevoy delivers on all its claims in real-world vehicle integration remains to be seen — CATL has a track record of optimistic spec sheets that sometimes don’t translate directly to vehicle-level performance. But the direction of travel is clear: 1,000 km of EV range without a massive battery pack is approaching fast.
