Caterham’s Electric Project V uses immersion cooling technology

Caterham electric car’s new battery has energy density of 200 Wh/kg

Caterham continues to push forward with its first all-electric sports car, and shortly after confirming it will use Yamaha’s electric motors, the British company revealed it will hire a Taiwanese supplier to provide an innovative immersion-cooled battery pack.

The battery pack will be from Xing Mobility, with its cells immersed in a dielectric liquid. This greatly improves heat dissipation compared to traditional liquid-cooled battery packs. Caterham also said that the Xing’s battery energy density is 200 Wh/kg, which should provide sufficient range for electric vehicles.

There’s no word yet on how big the car’s battery pack will be, how much it will weigh, or how quickly it’s expected to charge. However, considering that the Project V prototype is a compact sports car, one cannot expect it to be very large. When first announced last year, Caterham said its new electric car would use a lithium-ion battery pack with a capacity of 55 kWh, enough to give it a range of 249 miles (400 kilometers).

The claimed energy density is 200 Wh/kg, which is comparable to some other batteries on the market. For example, CATL’s new Shenxing Plus electric lithium iron phosphate battery has an energy density of 205 Wh/kg, while the energy density of Tesla’s 4680 battery cell is 296 Wh/kg.

As mentioned earlier, Xing batteries will power Yamaha’s e-Axle. The original Caterham concept featured a single motor with 268 hp, and the production model is likely to have about the same power.

Shoppers interested in the all-electric Caterham sports car may have to wait a while to get their hands on one. The brand initially hoped to launch a production model in 2026, but CEO Bob Laishley recently admitted that “2026 will be a challenge.” He also revealed that Caterham has yet to decide where to build the car, although the company has said it will not build it at its existing Dartford, UK, factory.
