Electric vehicle battery for 1,000km on a single charge

China's CATL company said on June 23 that the third-generation battery with outstanding energy efficiency will start production next year .

CATL's new generation of batteries - named Qilin (Unicorn) after a mythical Chinese creature - will feature energy densities of up to 255 Wh/kg and deliver record mass utilization efficiency. 72%. It achieves the highest level of integration to date in the world, easily providing a vehicle range of more than 1,000 km on a single charge.

Qilin also equips micrometer-sized bridges inside the interlayer.

With the same chemistries and the same package size, Qilin batteries provide 13% more power than 4680 batteries, achieving a comprehensive improvement in operating range, charging speed, safety, age lifespan and performance.

CATL has integrated a liquid cooling pad and heatsink into the multifunctional elastomer interlayer inside the battery. Qilin also features micrometer-sized bridges inside the interlayer, which dynamically adjusts to changes inside the battery cell, thereby improving battery reliability over its entire life cycle.

The integrated power unit, consisting of battery cells and multifunctional elastic interlayer, creates a more stable load-bearing structure perpendicular to the driving direction, which enhances the shock and vibration resistance of the vehicle. battery.

Qilin's ingenious bottom-sharing design allows for intelligent arrangement of various components, including structural protection, high-voltage connections and a vent for heat dissipation, increasing battery capacity by 6%.

The battery is cooled by liquid coolers placed between adjacent cells and pioneering large surface cell cooling technology that quadruples heat transfer area, halving heat control time, and supporting Supports hot start in 5 minutes and quick charge in 10 minutes.

Furthermore, Qilin has achieved thermal stability and safety for all chemical systems, making it compatible with materials with higher energy densities.

CATL's third-generation battery series is expected to begin mass production and be on the market in 2023. The Chinese technology company did not disclose whether any electric vehicle manufacturers have ordered Qilin batteries or not. not yet.

From simulated computing in the microcosm to the artful streamlining of the battery structure, CATL emphasizes a constant focus on technological innovation, aiming to accelerate the development of powered vehicles. electricity instead of fossil fuels.
