Successful solutions to self-discharge problem in MgFC

1) Magpower systems successfully solved the self-discharge problem by using “hydrogen inhibitors” as its properietry technology. Reference is made to the company’s website.
2) Susumu Suzuki succeeded in solving the self-discharge problem by using a polyvalent carboxylate aqueous solution. For details, reference is made to WO/2011/125150 MAGNESIUM BATTERY.
3) Prof. Kohama solved the same problem by using a flame-retardant magnesium alloy for the negative electrode. The technology is detailed in JPA No. 2012-234799.
South-Korea's MgFC recently developed is newsed. The researchers succeeded in driving the car a distance of 200 km by the MgFC of 40 kg set on the car.
The positive and the negative electrodes of the MgFC are improved and the battery structure is changed. The results are that the chemical reaction efficiency at the negative electrode and the chemical reaction rate are both increased, and that the energy efficiency and the energy density are doubled when compared with those of the conventional one.
It is unknown how to overcome the self-discharge problem inherent to the MgFC and the Mg danger problem.
