直流快速充电技术大大提高了电动汽车的实用性,电池组从空电状态到满电量80%的充电时间仅有半个小时或者更少。但快速充电技术被普遍认为存在一个缺陷:缩减锂离子电池组的使用寿命。近日一篇发表在《自然材料》(Nature Materials)杂志上的研究成果显示,快速充电对电池组的损害,可能没我们想象的那么大。这一研究结果来自斯坦福大学和斯坦福材料科学中心的科研团队。研究人员先制造了一批硬币式电池,然后利用不同电流大小和不同充电时间长度,对它
DC fast charging technology greatly improves the practicality of electric vehicles, the battery pack from the empty state to full charge of 80% of the charging time is only half an hour or less. However, rapid charging technology is generally believed that there is a flaw: reduce the service life of lithium-ion battery pack. A recent study published in the journal Nature Materials shows that rapid battery damage may not be as dramatic as we would expect. The findings came from research teams at Stanford University and Stanford Materials Science Center. Researchers first created a coin-cell battery, and then use different current sizes and different charging time length, it
