Nissan and the Portuguese government have agreed to study the establishment of a plant in Portugal to produce lithium-ion batteries to be installed in electric vehicles, Nissan has said.

Nissan plans to establish a joint venture with a Portuguese company to produce the batteries.

Nissan, in a joint venture with the NEC Corp. group, plans to start producing lithium-ion batteries at Nissan’s Zama factory in Zama, Kanagawa Prefecture, by March 2010 and to produce electric vehicles at its Oppama factory in Yokosuka in the same prefecture.

Nissan plans to start selling electric vehicles in Japan and the United States in 2010 and launch such vehicles in Portugal in 2011.

Portugal, under an agreement with the Renault-Nissan alliance, plans to build 1,300 recharging stations for electric cars by 2011, Nissan said.
