主题:【求助】“锂电充电只需十秒”!谁帮着核实下这条消息。。。 -- 起于青萍之末
"If transport of the lithium ions was so fast, something else had to be the problem," Ceder said.
Further calculations showed that lithium ions can indeed move very quickly into the material but only through tunnels accessed from the surface. If a lithium ion at the surface is directly in front of a tunnel entrance, there's no problem: it proceeds efficiently into the tunnel. But if the ion isn't directly in front, it is prevented from reaching the tunnel entrance because it cannot move to access that entrance.
似乎是在变层所谓的通道口(或者说surface to the diffusion channel)做了一个量子阱,锂离子直接从那里走,从而提高迁移率。碳包覆应该是从晶格上做文章吧。这里还有一个他们的数据。

🙂老兄 您看没看人家的工作啊?哪里是碳包覆这么简单啊 菜菜丛 字118 2009-03-12 19:06:37
🙂什么叫缺陷层?就是包裹上一层非结晶体的焦磷酸 积吉 字0 2009-03-13 02:26:37
🙂按mit news的说法
🙂我好奇他这个beltway,从字面上理解是在电极外修了。 1 起于青萍之末 字96 2009-03-12 20:20:19
