In the United States, regulations now require EV batteries to retain 80% of their original charge capacity after eight years of use. This push is pivotal in ensuring EVs become a more viable and sustainable transportation option.<\/p>\n
Recent breakthroughs at Dalhousie University may signal a major leap forward, promising significant improvements in EV battery life and the future of energy storage.<\/p>\n
Researchers at Dalhousie University, in collaboration with the Canadian Light Source (CLS) at the University of Saskatchewan, have developed a groundbreaking lithium-ion battery material known as a single-crystal electrode<\/a>.<\/p>\n This innovation has undergone relentless testing in a Halifax lab, where it has been charged and discharged continuously for over six years.<\/p>\n The results? Remarkably, the battery demonstrated durability over 20,000 charging cycles before reaching the industry standard 80% capacity threshold.<\/p>\n This translates to an extraordinary lifespan of approximately 8 million kilometres of driving, dwarfing the performance of traditional lithium-ion batteries, which typically endure around 2,400 cycles or 960,000 kilometres before hitting the same benchmark.<\/p>\n To uncover the reasons behind this extended lifespan, researchers conducted a detailed analysis of the battery materials using advanced tools at the CLS.<\/p>\n In conventional batteries, the electrode material suffers from extensive microscopic cracking caused by the repeated charging and discharging process. Over time, these cracks lead to the material\u2019s gradual pulverisation, ultimately reducing the battery\u2019s performance and capacity.<\/p>\n By contrast, single-crystal electrodes demonstrated remarkable resilience. Even after prolonged use, these electrodes exhibited minimal mechanical stress and appeared nearly identical to new cells.<\/p>\n This inherent durability makes them ideal candidates for repurposing after their primary use in EVs, extending their utility to applications such as energy storage for wind and solar farms.<\/p>\nWhy single-crystal electrodes last longer<\/h3>\n
Why advancing EV battery life is critical to adoption<\/h3>\n
