How much ten times the energy amount, the world's first "battery that can be charged with air" appears

As a new battery following the lithium ion battery currently mainstream, fuel cells andBatteries using genetically engineered virusAlthough it is cited, it became clear that a new "battery that can be charged from air" appears.

Although it is unbelievable battery at the least, what kind of principle can we charge by the principle? In addition, this battery seems to be able to realize ten times as much energy as before.

Details are as follows.
World's first battery fuelled by air - Telegraph

According to this article, currently BritishSt Andrews UniversityIt is said that a revolutionary rechargeable battery called "STAIR (St Andrews Air) battery" has been developed for mobile phones, laptop computers, electric cars, etc.

Basically, this battery is a mechanism to store electricity in the same way as the conventional one, but if it consumes electricity or becomes empty, it will charge oxygen from the surrounding air and charge it .

Although it is the principle of charging which is worrisome, oxygen taken from the periphery causes a chemical reaction with the porous carbon component in the battery, so that it performs the same function as the conventional charging with lithium cobalt oxide It is possible to do.

And by recharging with air, we can realize energy saving up to 10 times with the same size as conventional battery, so we can make it smaller and lighter.

It is a ridiculous battery, but when will it actually come out? The next report is awaited.

In addition, details of the "STAIR (St Andrews Air) battery" announced this time on the above link are posted, but according to the reader's point of view, this battery"A lithium-air battery" of a new structure announced on February 24 by the National Institute of Advanced Industrial Science and Technology (AIST) (AIST)It seems to be the same thing.

This is when discharging a new structure "lithium-air battery". The same applies to porous carbon and air.


When charging it is like this. In addition, it is precisely a new type fuel cell that uses metallic lithium as fuel instead of air.
