记者日前从中国科学院深圳先进技术研究院获悉，该院多个科研团队联合东华大学团队，成功研发出如 头发丝般纤细、柔软可拉伸、能自由驱动的神经纤维电极——"神经蠕虫"。该研究首次提出脑机接 口"动态电极"新范式，打破植入式电极的"静态"传统，为脑机接口电极研究与应用开辟新方向。相关研 究论文发表在《自然》杂志上。 在脑机接口等神经接口系统中，电极是连接电子设备和生物神经系统的核心界面传感器。然而，当前植 入式电极均为静态，且植入后只能固定位置、局限采集，制约着脑机接口的应用和发展。 科研团队利用微创植入技术，成功实现神经纤维电极在大鼠腿部肌肉内稳定工作超过43周。植入13个月 后，其周围形成的纤维包裹层厚度平均不足23微米，周围组织的细胞凋亡率与正常组织相当。相比之 下，传统不锈钢丝电极在相同条件下包裹层厚度超过451微米，且伴随显著的细胞凋亡反应。 此外，在外部磁场的操控下，神经纤维电极不仅能在肌肉表面游走，还可在植入后的一周内，每天变换 位置监测电极信号。 （文章来源：科技日报） 科研团队经过5年攻关，通过超薄柔性薄膜制备、导电图案设计等多个精细步骤，开发出直径仅196微 米、柔软可拉伸且能容纳60个独立信号通道 ...

科学研究发现，固态电解质界面层中的氟化锂在保障电池性能方面发挥着关键作用。2022年，向宇轩团 队在给锂电池做核磁共振检测时发现异常：电池内氟化锂的谱图与标准纯相样品存在细微差异。其中一 个此前未被报道的波峰信号引起了他们的注意。 研究团队采用多核、多维固态核磁共振技术，对固态电解质界面层中氟原子与锂原子进行深度分析。团 队放大氟原子谱图后发现，原本单一的波峰实为两个波峰的叠加，其中一个可能源自未知界面成分。进 一步检测后，团队推测该未知成分含氢元素。 为验证这一猜想，他们合成不同氢含量的氢掺杂氟化锂样品进行对比测试。结果显示，氢含量高的样品 正是异常波峰的来源。进一步检测证实，电池中的氟化锂是由锂、氟、氢构成的固溶体结构。西湖大学 工学院助理教授朱一舟团队通过第一性原理计算发现，氢的掺入使锂离子迁移势垒降低，即锂离子在氢 含量高的环境中，更容易"动起来"，因此有利于电池性能的提升。 测试还发现，许多性能优异的锂电池中，普遍存在高含量的氢掺杂氟化锂。在下一代锂金属电池中，氢 掺杂氟化锂能显著优化负极性能。 记者日前从西湖大学获悉，该校工学院研究团队首次揭示锂电池电极界面层中的关键物质——氟化锂并 非纯相，而是 ...
