Williams told Aviation Week that switching from lithium back to nickel cadmium would require significant engineering work with both space and weight penalties. Airbus was not immediately available to comment on the article.
Brazilian planemaker Embraer SA declined comment when asked if it planned to rethink its use of lithium-ion batteries on its military transport plane and new business jets.
The Embraer programs use a battery made in the United States, unlike the Japanese one on the 787.
Lockheed Martin Corp, maker of the F-35 Joint Strike Fighter, has said it does not see a problem since the lithium-ion batteries on the military plane are made by France’s Saft Groupe, not Yuasa.
