The team tackled the problem of vanadium oxide dissolving inside the battery—a key reason for quick battery degradation.
By combining vanadium oxide with a highly conductive material called MXene, they created a composite that keeps the battery stable and boosts ion flow.
Tests showed these improved batteries kept more than 73% of their capacity after 100 charge cycles and still held 59% after 500 cycles, way better than regular aluminum batteries.
This could mean more durable, budget-friendly energy storage in the future!
