| titleOfInvention | Preparation method and application of germanium-carbon nitrogen nano composite material |
| abstract | The invention discloses a germanium-carbon nitrogen nano composite material and a preparation method thereof. Firstly, germanium oxide nano wires are evenly dispersed in liquid-state organic ester, pyrrole, polyvinyl acetate and oxidative metal chlorine salt are added, and full stirring is performed for reaction so as to generate a germanium oxide-carbon nitrogen composite precursor; secondly, calcination is performed at the temperature of 600-1000 DEG C in the reducing atmosphere to obtain the germanium-carbon nitrogen nano composite electrode material; germanium nano particles in the prepared germanium-carbon nitrogen nano composite electrode material are mutually separated at intervals of certain distances and are injected into carbon nitrogen nano tubes in a sectioned mode to form a legume structure. The composite material prepared by means of the preparation method can be applied to lithium ion batteries, pores among discontinuous germanium particles in the material effectively buffer volume change occurred in the germanium charge-discharge process, meanwhile coating of a carbon nitrogen layer facilitates decrease of contact resistance and formation of a stable solid electrolyte interface, the electronic electric conductivity and electrochemical stability of electrodes are improved, and excellent lithium storage performance is shown. |
