中国科学家的锂离子修复技术能延寿六倍

2025-02-19 23:58 by 水刀子

上海复旦大学的研究人员在《自然》期刊上发表论文,报告开发出一种革命性的修复技术,可使锂离子电池的使用寿命延长六倍以上。研究人员表示这种低成本的、环保的技术有望迅速投入市场。复旦大学团队研究发现,电池的“寿命”其实和人体健康类似,其老化问题往往集中在某个核心部件,也就是活性锂离子。如果能精准补充损失的锂离子,就能大大延长电池的使用时间。基于这个想法,团队开发了一种像“药物”一样的锂载体分子,可以通过注射的方式补充电池中的锂离子。研究人员说,一个商用的磷酸铁锂电池,按照以往来说,在使用 2000 次之后,就会容量衰减、报废。有了这项技术,可以使它在使用 12000 次之后,还能够保持一个接近于初始电池的“健康”状态。

Telegram | DID YOU KNOW?

Date: |

On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. In addition, Telegram now supports the use of third-party streaming tools like OBS Studio and XSplit to broadcast live video, allowing users to add overlays and multi-screen layouts for a more professional look. Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram.
