Rechargeable aluminum battery advent technology needs further improvement

A few days ago, a Chinese-dominated research team at Stanford University in the United States published a research report in the online edition of the journal Nature, introducing their newly developed aluminum battery with high efficiency and durability, ultra-fast charging, low flammability, low cost and other characteristics, which can become a safe alternative
to conventional batteries.

The research team used graphite as the anode material, experimentally confirmed several graphite materials with good performance, and used a plasma liquid equivalent to a salt solution as the electrolyte, thereby solving the bottleneck problem of aluminum battery research in materials
.
Dai Hongjie, head of the research team, pointed out that the aluminum ion battery they developed can be charged and discharged, and has the outstanding advantages
of ultra-fast charging, non-combustible explosion, foldable and low material cost.
This is a major breakthrough in the development of rechargeable aluminum batteries, which were largely non-existent before, especially those with these properties
.

The researchers said that because the plasma electrolyte does not burn, aluminum and graphite are not easy to burn, so this aluminum battery is very safe
.
To test the safety of aluminum batteries, the researchers drilled holes in batteries that did not explode and still operated for a period of time
, according to the study.

Dai Hongjie said that the aluminum battery they developed can replace alkaline batteries that are easy to pollute the environment and lithium-ion batteries
that are at risk of combustion.
In the future, this aluminum battery could also be used to store renewable energy in the grid, and could also be used in electric vehicles
.
However, the current aluminum battery technology needs to be further improved, such as the need to increase the energy density of aluminum batteries
