A nanoscale meshed electrode of single-crystalline SnO for lithium-ion rechargeable batteries

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)(4) as 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.
