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。

But Kliuchnikov, the Ukranian now in France, said he will use Signal or WhatsApp for sensitive conversations, but questions around privacy on Telegram do not give him pause when it comes to sharing information about the war. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. False news often spreads via public groups, or chats, with potentially fatal effects.
