Beyond Lithium-Ion: Sodium-Ion vs. Solid-State vs. Lithium-Sulfur – Who Wins the Next Battery Race?

Beyond Lithium-Ion: Sodium-Ion vs. Solid-State vs. Lithium-Sulfur – Who Wins the Next Battery Race?

CATL began deploying the world’s first mass-produced sodium-ion EV battery, Naxtra, in late 2023, with pack costs at $77/kWh and a target of $40/kWh after scaling. CATL’s sodium-ion cells deliver up to 175 Wh/kg, with a second-generation cell expected to exceed 200 Wh/kg. Toyota projects its solid-state lithium packs, due in 2027–28, will boost range by 20%. LG Energy Solution plans to mass-produce lithium-sulfur batteries by 2027.
