Japan to promote 'air battery' practical storage capacity lithium battery 5 to 10 times

Reference news network reported on March 19, according to Japanese media research and development of Japanese companies have greatly increased air battery service life of technology, service life is & other; The ultimate battery & throughout; The biggest issue of air batteries. Fujitsu's development of hydrogen - FDK company Three years after air fuel cell is expected to realize the practical application. Japan telecom telephone company ( NTT） Developed service life longer lithium air batteries.

according to 'Japanese economic news' reported on March 18th, air battery not only light, and high performance, all sorts of equipment need to collect data, will be a growing demand for air batteries. If solar and other renewable energy to produce excess power storage systems were popular, is expected to significantly reduce carbon dioxide emissions.

according to the report, with the emergence of a lithium-ion battery, portable equipment rapidly, support the development of the IT revolution. Lithium battery performance, is an important part of a support electric car. However, lithium battery technology gradually close to the limit, but also inflammable shortcomings and so on.

air cell is a new generation of technology, one of the powerful candidate can react with oxygen in the air to generate electricity. Because the oxygen can be an unlimited supply, air battery storage capacity is theoretically lithium battery of 5 to 10 times.

reported that the development of the FDK air cell is by making hydrogen and oxygen react to generate electricity. Effective use of the structure of the hybrid vehicles use nimh batteries, will use nickel anode for oxygen, to join the main ingredients for ruthenium particles, to promote the reaction. Even for 500 times, the performance degradation rate of less than 10%. If it is used to store renewable energy electricity, you can use 10 years or so.

the development of the NTT is negative USES lithium lithium air batteries, even for 100 times, the performance also won't fall. Join the main components in manganese compounds is the key, can play a catalytic role, promote the charge and discharge the necessary chemical reactions. If according to the previous methods, after a few charge and discharge, battery performance will drop.
