Abstract

The invention discloses an SiCO-carbon nanotube composite film electrode for a lithium battery. The SiCO-carbon nanotube composite film electrode comprises a single-crystal silicon-based plate (1), wherein a TiN barrier layer (2), a Cu film layer (3), a CuO film layer (4), a SiCO film layer A (5), an Ni catalysis layer (6), a carbon nanotube layer (7) and an SiCO film layer B (8) are sequentially arranged on the single-crystal silicon-based plate (1). By adopting the SiCO-carbon nanotube composite film electrode, not only is the circulation stability of the electrode effectively improved, but also the thickness of a single film layer can be greatly reduced, a relatively large thickness of a film system can be achieved, and thus the electrochemical property of a material in high-magnification power charge / discharge can be improved.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a SiCO-carbon nanotube composite film electrode for lithium batteries. Background technique [0002] Lithium ion has a series of advantages such as high energy, long service life, light weight, small size, etc., which has attracted widespread attention and attention from the international battery industry and the scientific and technological circles. Lithium battery applications mainly include energy storage batteries for portable devices and power batteries for new energy vehicles. The former mainly includes 3C products, namely computers, communications and consumer electronics products. The number of mobile phone users around the world is increasing at a rate of about 15%-25%, and the development of notebook computers that use lithium batteries for 50%-70% of their batteries will increase the demand for lithium-ion batteries year by year. As countries around the world pay mor...
