    Birth of the Strong HEART

    With safety as our priority, we strive to improve energy and power density, extend service life, and build superior high- and low-temperature performing battery cells. While satisfying all-round checks of material, electrode engineering, mechanical structure, technology, equipment, quality, supply chain, and recycling.

    Performance Leading Battery Cells Introduced by CATL

    • EnerSpeedy

      The ground-breaking “fast ionic ring” and “super electronic network” technology establish a fast channel for the simultaneous influx of a large number of lithium ions, of which the diffusion rate is improved and ultimately achieves a battery life of 300 km with one charge of 15 minutes.

      300km
    • EnerMagic

      CATL uses NCM as a core material to significantly enhance the energy density of products to up to 240Wh/kg.

      240Wh/kg
    • EnerLasting

      Battery products have passed a number of abuse tests. Combining active protection and passive protection, CATL enables products to fully protect user’s safety.

    • EnerDura

      The introduction of the long-life battery cell extends the service life up to 15 years with 15,000 cycles.

      15000cycles
    • EnerClimate

      Equipped with superior environmental adaptability, the battery cells have stable performances ranging from -30° C to 60° C.

    Building-up of the Strong BODY

    We create flexible design modules and battery packs based on the needs of customers.

    And we ensure excellent system level performance and high consistency battery cell products..

    • Safe

      Execute topology optimization and topography optimization in the concept design phase; conduct size optimization, thermal analysis, and heat loss control early during the design; and implement random modal vibration, impact and extrusion tests during the design process to ensure the safety of final products.

    • Reliable

      From component level to battery system level (component level - battery level - module level - electric box level - battery pack system), have a good command of the safety and reliability of each component to ensure the overall safety and reliability of the products.

    • Durable

      Life expectancy of the battery pack has been evaluated with authoritative evaluation software, and the test result shows the service life can be up to 10 years.

    • Lightweight

      Reduce weight, remove excess material, accurately calculate the amount of material used, and confirm by simulation calculation to improve energy density and mileage.
