The president of Kyoto-based GS Yuasa Corp., the maker of lithium-ion batteries for Boeing Co.'s troubled 787 Dreamliner, said Monday that it is working with the plane maker to get the high-tech jetliners back in the sky as soon as possible.

In his first statement over the Dreamliner trouble, Makoto Yoda said, "We are sharing information and collaborating with Boeing" and other parties as well as the Japanese and U.S. authorities.

With Boeing 787s grounded around the world following a January emergency landing by an All Nippon Airways Co. Dreamliner experiencing smoke in its cockpit from an apparent battery fire, Yoda said, "Going forward, we will continue to work closely with Boeing to enable the resumption of its jetliner operations as soon as possible."

The statement came after a report last week that Boeing and GS Yuasa "are at odds over what should be included in the final package of fixes intended to get the jets back in the air" and which prompted the battery maker to stress the cooperative structure between the two firms, according to a company official.

"GS Yuasa development, design, production and quality teams are tirelessly applying their knowledge and engineering expertise 24 hours a day to ascertain the causes of the problems and improve the safety of the batteries," the battery maker said.
