Technology:
A
total of 11 organizations including Furukawa Battery, Nikon, and Nissan work
together on the project to increase the capacity of an air battery. In the
first stage, Furukawa Battery will put an emergency power source with a generation
capacity of 300 W for mobile devices into practical use within the year. The
project team aims to construct a system with a generation capacity of 3 kW for
household use in five years and a system with a generation capacity of 1,000 kW
that can be used for a small-size power plant in 10 years. Furukawa Battery is scheduled
to mass produce disposable air battery for emergency within the year.
An
air battery has 10 times higher energy density than a lithium-ion battery of
the same weight because magnesium used for the negative electrode radiates lots
of electrons. In addition, it is possible to simplify the structure of the
positive electrode. The existing technology does not allow an air battery to be
reused because the negative electrode oxidizes once it is exhausted. Nikon plans
to develop a mechanism to deoxidize the negative electrode made of magnesium utilizing
solar heat and waste heat of a manufacturing plant with a view to making an air
battery reusable for power generation.
