The Rundown: Researchers led by Professor Jeff Dahn at Dalhousie University have developed a single-crystal electrode battery capable of lasting over 20,000 charge cycles — equivalent to 8 million kilometers. This innovation far outpaces conventional lithium-ion batteries, which typically last 2,400 cycles.
The Context:
Why it Matters: With the potential to last decades, this breakthrough could redefine EV longevity and carbon efficiency. The technology also opens doors for second-life applications, like renewable energy storage, making EVs more sustainable and cost-effective long-term.
