China's 2% lithium-ion battery tax is back. Sodium-ion is not on the bill.
China restored a 2% consumption tax on lithium-ion batteries on 1 September 2026, rising to 4% a year later. Sodium-ion and solid-state can stay exempt through 2028.

Sodium-ion batteries are closing in on LFP cost parity, and the last excuse is energy density
CATL expects sodium-ion to match LFP on cost by the end of 2026. The chemistry's remaining problem is density — and two 2025 research papers just attacked it from different angles.

CATL's first sodium-ion sedan was held up by the factory, not the chemistry
CATL's Naxtra sodium-ion cell is going into the Changan Nevo A06 this year. The 45 kWh pack is a winter specialist, not a lithium killer, and CATL itself only plans 10,000 to 20,000 cars.
