Eco-friendly aluminum battery lasts 10,000 cycles and could
Most importantly, the battery lasted for 10,000 charge-discharge cycles, retaining more than 99% of its original capacity. The researchers also found that the aluminum fluoride
“The solid-state Al-ion battery had an exceptionally long life, lasting 10,000 charge-discharge cycles while losing less than 1% of its original capacity,” said the research team in a press release. This, along with its safety features and recyclability, makes it a very promising solution for storing energy from sources like solar and wind power.
To create the solid electrolyte, the researchers introduced an inert aluminum fluoride salt to the liquid electrolyte already containing aluminum ions. This new aluminum-ion battery could be a long-lasting, affordable, and safe way to store energy. American Chemical Society
Aluminum's manageable reactivity, lightweight nature, and cost-effectiveness make it a strong contender for battery applications. Practical implementation of aluminum batteries faces significant challenges that require further exploration and development.
These electrolytes, typically composed of aluminum chloride, are corrosive to the battery's components and highly sensitive to moisture. This can lead to a decline in performance over time and pose potential hazards. The newly developed aluminum-ion battery overcomes these hurdles by using a solid electrolyte.
