    CATL: sodium ion battery breakthrough?

    CATL produces one-third of the world’s lithium ion batteries. Its patents have warned of devastating lithium shortages since at least 2016. Hence in 2021, it announced it would produce commercial sodium-ion batteries by 2023. The technical challenges are captured in its patent library. We cannot fully de-risk its 2023 target.

  • Lithium ion batteries: energy density?

    Lithium ion batteries: energy density?

    Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy densities doubling to 500Wh/kg in the 2030s, trebling to 750 Wh/kg by the 2040s, and the best possible energy densities are around 1,250 Wh/kg.
