Since 2010 the leading scientists from around the world are working on creating a fundamentally new source of energy – rechargeable aluminium-ion battery.
The material of the anode became the main stumbling block for the researchers. Earlier experiments used pure aluminium, which did not produce the desired results – oxide film was formed that prevented the passage of ions and after 20-50 charging-discharging cycles the battery lost up to 50% of its capacity.
As a result, the scientists thought of the possibility of improving aluminium to achieve better performance.
The scientific staff of the Institute of High-Temperature Electrochemistry of the Ural Branch of the Russian Academy of Sciences (IHTE UrB RAS) have made great achievements in this regard. They had previously created the aluminium-graphene composite using the unique technology of introducing nanografene into aluminium.
Comprehensive studies of this composite have shown that a certain percentage of graphene and aluminium makes this composite the ideal material of the anode for the rechargeable current sources.
The received information served as a starting point for the development works of creating a laboratory sample of the battery cell. The assembled cell is superior in all parameters compared to the available analogues of the aluminium-ion cell: number of charging-discharging cycles without capacity loss is of at least 100, in the four months of storage the cell has not lost its efficiency and performed another 100 cycles without capacity loss.
The advantages of the rechargeable power supply with aluminium anode over the lithium-ion battery are obvious:
Currently investors are being sought to finance the creation of the industrial prototype. In the long term, this type of current source can be used primarily in stationary energy storage devices: network energy storage devices for industrial facilities and private houses; uninterrupted power supply at critical sites (hospitals, airports, railway, military industrial complex facilities); emergency mobile energy storage devices; energy recovery systems; alternative power sources; support for electrical charging stations for electric transport, etc. The next step in this direction for the developers is the use of aluminium-graphene-ion power sources in modern electric transport.
The first laboratory cell was created IHTE UrB RAS in cooperation with United Company RUSAL, which is a member of the Aluminium Association.
