The battery is expected to last at least two decades in grid energy storage

The power cell uses a nickel-rich alloy for its cathode. The alloy contains 50% nickel, 20% cobalt, and 30% manganese and is considered to be very stable.

The cells’ ratio of energy storage ability to weight is 20% higher than that of the cathodes used in lithium-ion batteries used in electronic devices.

According to the researchers — who have been working on the model for over three years- their product should serve as a benchmark for academics and companies developing advanced lithium-ion cell chemistries.

“These results are far superior to those that have been used by researchers modelling cell failure mechanisms and as such, these results are more representative of modern Li-ion cells and should be adopted by modellers,” researchers wrote.
