A groundbreaking innovation in battery technology for electric vehicles redefines both durability and performance. Developed by Canadian Dalhousie University researchers new type lithium-ion The battery can withstand more than 20,000 charge-discharge cycles before reaching its 80 percent capacity limit. about 8 million kilometers can go a long way.

This battery, which has demonstrated superior performance in uninterrupted tests conducted for six years, aims to extend the life of electric vehicles and reduce their environmental impact. US electric vehicle batteries 8 years after use 80 percent capacity The regulation that requires protection can be easily met with this new technology.

More importantly, researchers believe such durable batteries could last beyond the life of the vehicle. At the end of their useful life, batteries can be reused for energy storage in wind and solar power plants.

Single crystal electrode technology

At the center of this important invention is a battery technology using single crystal electrodes. Dalhousie University researchers at the Canadian Light Source (CLS) facility at the University of Saskatchewan, Canada. standard ve with single crystal electrode that’s lithium examined batteries at the microscopic level. Thanks to CLS’s high-end synchrotron beam technology, the internal structure and degradation mechanisms of the batteries could be analyzed in detail. These examinations showed that the electrodes of standard batteries cracked due to lithium movement and almost turned into dust over time. However, in a single crystal electrode battery, even after six years of use any between a new cell and difference could not be detected.

Researchers attribute this difference in durability to the structure of the electrode materials. The electrodes of standard batteries consist of small crystals, like a snowball formed by snowflakes coming together, and this structure tends to crack over time. In contrast, the single crystal electrode battery More resistant to stress and pressure It acts like a big ice cube.

Researchers say that thanks to lithium-ion technology that will last 8 million kilometers, batteries will last longer than other components of the car and will no longer be the limiting factor. Let us also point out that an average vehicle travels 20 thousand kilometers per year. senior scientist at CLS Toby Bond in the press release, “We really need these vehicles to last as long as possible, because the longer you use them, the better the improvement in carbon footprint.” he said. Bond said the new batteries are already commercially produced and their use is likely to come in the future. in a few years He says it will increase significantly.
