Scientists from the University at Buffalo conducted an experiment with new generation battery designs. During
New electrode design causes shifts inmagnetic field as the ions move as the battery charges and discharges. By observing this process, you can monitor battery life with a high degree of accuracy.
Using vanadium, chromium and cyanide, scientists createda new magneto-ion material, which they used as a molecular magnetic electrode in a lithium-ion battery. The material changes its magnetism as lithium ions move in and out. Using a ferromagnetic resonance testing device, they were able to measure these changes to determine the battery's charge level.
According to the team, the magnetic electrode forion monitoring demonstrates a 2,000% increase in accuracy and an increase in response time of more than 5,000% compared to previous approaches. The scientists say the material's characteristics make it ideal for use in rechargeable batteries and will help monitor battery states of charge in real time.
