Background

However, tin dioxide is used as member of metal oxide, has the characteristics of low price and simple synthesis process, can store a large amount of lithium ions, and is main directions of future development of electrode materials of the lithium ion battery.

In various carbon materials, including carbon nano tubes and graphene, the carbon material can be used as an effective carrier for loading the tin dioxide, however, the preparation process of the material is more complex no matter the carbon nano tubes or the tin dioxide, and the cost is higher, so that the search for materials which have simple synthesis processes or can be directly used as carbon sources has great cost advantages and technical advancement for the composite material.

As deciduous trees, the scaphium scaphigerum is native to Vietnam, India, Thailand and the like, is suitable for being planted in tropical regions, meanwhile, the seeds of the scaphium scaphigerum plant are in a spindle shape or an oval shape after being dried, and the seeds of the scaphium scaphigerum are divided into three layers, wherein the pericarp of the middle layer is thicker, and is expanded into a sponge shape when meeting water, meanwhile, the surface of the middle layer has various functional groups which can absorb a large amount of ions, and the middle layer.

Therefore, the boat-fruited sterculia seed can be used as a carbon source to be compounded with the tin dioxide, kinds of researches are simple to operate, the process requirement is not harsh, the high-quality and large-scale preparation of the tin dioxide compounded boat-fruited sterculia seed as the carbon source material can be realized, and the method is a focus of attention of current science and technology workers and industrial engineers.
