Contemporary Amperex Technology (CATL) has introduced the Freevoy Super Hybrid Battery, touted as the world’s first hybrid vehicle battery to provide a pure electric range exceeding 400km and 4C superfast charging capability.
The Chinese battery manufacturer claims that the latest product will redefine the charging experience for extended-range electric vehicles (EREVs) and plug-in hybrid vehicles (PHEVs), offering drivers the freedom from frequent charging.
The Freevoy battery boasts “remarkable” charging speeds, allowing for a 280km range replenishment in just ten minutes, claimed CATL.
Rapid charging capability of the Freevoy battery is expected to alleviate the common concern of range anxiety among EREV and PHEV owners.
The battery’s features surface modification technology for the cathode material and a novel high-voltage electrolyte formulation, creating a nano protective layer that “minimises side reactions within the active layer”.
Incorporating high-activity, excited-state particles into the cathode material greatly enhances the efficiency of lithium-ion transport.

By GlobalDataWith the support of the SOC full-scene high-precision model developed by CATL, along with advancements in BMS intelligent algorithms and hardware, Freevoy has achieved a 40% increase in SOC control accuracy. This has led to an overall enhancement in pure electric utilisation by over 10%, allowing for a pure electric range exceeding 400km.
The manufacturer also reports a 20% improvement in hybrid vehicles’ power performance through creation of a sophisticated multi-level power prediction and control strategy.
CATL’s advanced sodium-ion technology enables the Freevoy battery to operate efficiently in extreme low temperatures, ensuring a seamless driving experience even at -40℃.
To optimise low-temperature performance, CATL has introduced three key technological innovations based on sodium-ion battery technology.
These include the AB battery system integration technology, which combines sodium-ion and lithium-ion batteries to boost low-temperature range by 5%.
CATL uses sodium-ion batteries as a SOC benchmark to monitor the AB battery system, aiding in the calibration of the lithium-ion battery’s charge level. This approach improves system control precision by 30% and extends the pure electric range by over 10km.
Several vehicle brands, including Neta, Li Auto, Avatr, Deepal, and Changan Nevo, are reported to have already incorporated the Freevoy battery into their models.
CATL anticipates next year launch of an additional 30 hybrid vehicle models, equipped with Freevoy battery, from manufacturers such as Geely, Chery, GAC, and Voyah that are equipped with the will be launched.
