Boeing says use of lithium-ion battery right choice for 787

TOKYO (Reuters) - Boeing Co Ltd <BA.N> said on Friday the use of lithium-ion batteries was the right choice for its 787 Dreamliner passenger jet.

The planemaker also said it has asked Japan's GS Yuasa Corp <6674.T>, which makes the battery for 787, and France's Thales SA <TCFP.PA>, which produce the battery system for aircraft, to improve production standards to eliminate "variation" in battery cell production.
