"By 2010, we will accelerate our global plug-in hybrid R&D program.
As part of this plan, we will deliver a significant fleet of PHEVs
powered by lithium-ion batteries to a wide variety of global
commercial customers, with many coming to the U.S.
To make that happen, we have already started the planning phase to
expand our Panasonic joint-venture battery factory. The expansion
will add an assembly line
to build lithium batteries for automotive applications."
