Research at Dalhousie University has unveiled a revolutionary lithium-ion battery that far exceeds standard performance metrics. Utilizing a powerful synchrotron, scientists studied the longevity of a new battery design featuring a single crystal electrode, revealing it can endure over 20,000 charge-discharge cycles while retaining at least 80 percent capacity.
After six years of rigorous testing, the findings suggest that if implemented in electric vehicles (EVs), this battery could enable travel distances nearing five million miles (approximately eight million kilometers). The U.S. legislation mandates EV batteries maintain 80 percent efficiency for eight years, but advancements like this may allow batteries to outlast the vehicles themselves.
With the potential for repurposing these batteries for renewable energy storage after their vehicle lifecycle, understanding battery degradation is crucial. The Canadian Light Source aided researchers by allowing microscopic analysis of battery performance without disassembly.
The contrast between traditional and cutting-edge battery electrodes is staggering. While conventional designs suffer from structural decay due to particle interactions, the single crystal structure demonstrated remarkable stability over time. Researchers equate standard electrodes to fragile snowflakes, whereas the single crystal design is akin to a robust ice cube.
As battery technology progresses, upcoming commercial models of these innovative cells are expected to revolutionize the market, contributing to enhanced sustainability efforts in the automotive industry. The full research findings are available in the Journal of The Electrochemical Society.
