Lithium-air batteries could extend EV range, but major hurdles remain
Lithium-air batteries could one day give electric cars more than 2,000 km of range, according to claims about the technology.
The idea is linked to Chinese battery maker CATL, whose chief scientist Wu Kai described it as a long-range research goal.
Unlike standard lithium-ion batteries, lithium-air designs use lithium metal and draw oxygen from the air, potentially storing more energy for their weight.
But the headline energy figure applies to the chemistry alone, and real batteries need extra equipment that reduces performance.
Moisture and carbon dioxide in the air can damage the battery, while filtering and humidity controls add weight and use power.
Recharging can also create harmful byproducts that wear the battery down, and the design must still deliver power quickly enough for a car.
CATL has given no launch timeline for lithium-air, and is instead focusing on sodium-ion and all-solid-state batteries that are closer to market.
Lithium-air batteries could potentially give electric vehicles much greater range, but they remain a research goal rather than a product buyers can get.
A report says the batteries could enable a range of 2,000 kilometres, or more than 1,242 miles.
CATL Chief Scientist Wu Kai described lithium-air as a long-range research goal at this year’s Equipment Powerhouse Forum, but CATL has not announced a launch timeline.
The technology faces challenges including damage from moisture and carbon dioxide in air, harmful byproducts during recharging, and the need for added equipment.
- Who
- CATL and its Chief Scientist, Wu Kai, are associated with the research goal. CATL has not promised a launch timeline.
- What
- Lithium-air batteries could potentially offer much greater energy storage and extend electric-vehicle range.
- When
- Wu Kai discussed lithium-air at this year’s Equipment Powerhouse Forum. The article was published on 2026-11-09.
- Where
- The Equipment Powerhouse Forum; its location is not stated.
- Why
- The batteries could store more energy for their weight by using oxygen from the air instead of carrying a heavy cathode material.
