【跨越1300公里，捐献给女儿母校珍贵的生命礼物】After a 1,300-kilometer journey from the city of Liupanshui in Guizhou Province, the body of Li Xiaohong, a former public servant, arrived at Shenzhen University yesterday. Li’s body will be used for medical education and research at Shenzhen University Health Science Center, where her daughter once attended.

大连理工大学王治宇教授在Advanced Materials上发表了题为“High-Energy and Safe Lithium Battery Enabled by Solid-state Redox Chemistry in Fireproof Gel Electrolyte”的论文。该工作利用聚合物锚定Li2S正极分子，使其发生固态氧化还原反应，并采用阻燃凝胶电解质，构建了一种高能量、高安全的准固态锂电池。这种化学反应不仅完全避免了活泼锂金属和氧对电池安全性的负面影响，而且完全消除了可溶性氧化还原中间体对电极可逆性的损害。分子级Li2S正极在酯类电解质中表现出较高的稳定性，从而最大限度地与硅负极兼容。优化后的电池具有超过750 Wh kg-1的高比能量，能够稳定循环500次，并表现出优异的倍率性能、耐高温性和无自放电特性。另外，还开发了一种阻燃复合凝胶电解质，以防止过热、短路和机械损伤。https://t.cn/A6XK2PeX
