New Research Shows EV Batteries Could Last Significantly Longer Than Expected

Studies reveal both advanced battery designs and real-world driving patterns extend battery life, potentially outliving vehicles themselves.

Researchers at Dalhousie University developed a single-crystal lithium-ion battery that retains 80% capacity after over 20,000 cycles, far outperforming standard designs.
A Stanford study found that real-world driving behaviors, such as frequent stops and accelerations, can increase EV battery longevity by up to 38% compared to lab testing standards.
The Dalhousie battery design shows minimal internal degradation, attributed to its robust single-crystal electrode structure, which resists cracking under stress.
Findings suggest EV batteries could outlast the vehicles they power, enabling second-life applications like grid energy storage and reducing environmental impact.
Longer-lasting batteries may ease pressure on global mineral supply chains, providing manufacturers more time to meet growing EV demand.
