CATL‘s three new batteries are poised to redefine the landscape of Electric Vehicles (EVs). As the world’s largest electric car battery producer, CATL has unveiled groundbreaking technologies that address key challenges in EV adoption.
Introducing the Freevoy Dual Power Battery
CATL‘s Freevoy Dual Power Battery is described as a battery within a battery. Its innovative design uses dual-core architecture, combining Lithium-ion and sodium-ion cells, to achieve a maximum range of 1500km. This technology ensures optimized performance under varying conditions. For example, sodium-ion cells provide power in cold temperatures until the battery heats up, at which point Lithium-ion cells take over.
Another feature is its self-forming anode, which constructs itself during charging. Unlike traditional pre-formed anodes, this advancement boosts energy density while enabling a compact design. CATL claims this battery marks a fundamental shift in solving EV range limitations.
Shenxing Superfast Charging Battery
The second innovation, the Shenxing Superfast Charging Battery, combines an impressive 800km range with ultra-fast charging speeds exceeding 1300kW. At these speeds, users can gain 520km of range in just five minutes. Even better, at low charge levels, the battery delivers 830kW of power.
A unique advantage of the Shenxing battery is its ability to perform in freezing conditions. At -10°C, a charge from 5-80% requires merely 15 minutes, ensuring consistent reliability in colder climates. This battery exemplifies how fast charging can parallel traditional fuel refueling times.
Sodium-Ion Innovation
CATL’s mass-produced Sodium-ion Battery, slated for December production, delivers significant benefits for affordability and performance. With an energy density of 175Wh/kg, this battery extends EV ranges to up to 500km while hybrids benefit from 200km of range. Sodium-ion batteries boast exceptional safety features verified through rigorous tests, including needle penetration and compression.
Another standout feature is the charging cycle life of over 10,000 cycles, equivalent to five million kilometers. In sub-zero temperatures down to -30°C, the battery charges from 30-80% in half an hour. This mix of durability, safety, and performance establishes sodium-ion cells as the foundation for future cost-effective EV models.
Affordability for the Mass Market
Using abundant raw materials, CATL’s sodium-ion batteries are estimated to cost 25-30% less than standard Lithium-ion cells. Analysts predict this could further drive EV adoption by making models significantly cheaper than combustion-powered vehicles.
With these three technologies, CATL continues to dominate the EV battery market—producing 38% of all EV batteries globally last year. The company has yet to confirm which automakers will deploy these innovations first, but their potential implications for EV affordability and performance are substantial.
