采用Sn6O4(OH)4制备的纳米网状SnO单晶电极作为锂离子二次电池的中间态，获得了比容量高、循环性能好的锂离子二次电池，而传统的SnO大块电极在锂离子插入/提取过程中体积变化较大，容易降解。网状结构的骨架将适合于通过松弛源于膨胀的机械应变来防止对电极的损害。
A high specific capacity with good cycle performance for lithium-ion rechargeable batteries was achieved by using a nanoscopically meshed electrode of single-crystalline SnO produced through Sn6O4(OH)4as the intermediate state, whereas conventional bulky electrodes of SnO readily degraded due to a large volume change during lithium-ion insertion/extraction processes. The skeletal framework of the meshed architecture would be suitable to prevent damage to the electrode through the relaxation of the mechanical strain originating from the expansion.
