Problems solved by technology

However, since polyaniline, as the cathode material of lithium-ion batteries, does not have a stable voltage platform and poor cycle stability, pure polyaniline does not yet have the conditions to be widely used as cathode materials for lithium-ion batteries.

Embodiment 1

[0055] Example 1: PAnFc, P(An-co-AnFc)(2:1), P(An-co-AnFc)(3:1), P(An-co-AnFc)(5:1)

[0056] Synthesis of 6-(2-nitrophenoxy)hexanol: add 40mLN,N-dimethylformamide to a pre-dried 250mL three-neck flask, then add o-nitrophenol (2.78g), 6- Chlorohexanol (3.28g) and sodium hydroxide (1.2g) were stirred, the temperature of the reaction solution was raised to 60°C, and the reaction was continuously stirred for 72h. At the end of the reaction, extract the reaction mixture with dichloromethane to obtain the oil phase extract and dry it with anhydrous magnesium sulfate powder, then remove the solvent with a rotary evaporator, and the remaining product is separated and purified by column chromatography. The stationary phase is selected from 300 mesh silica gel. The phase was eluted with n-hexane / ethyl acetate (volume ratio 100:1), and the eluent was evaporated to remove the solvent to finally obtain 3.73 g of 6-(2-nitrophenoxy)hexanol with a yield of 78%. The product was Light green li...

Description

technical field [0001] The invention belongs to the technical field of lithium-ion batteries, in particular to aniline derivative polymers (homopolymers and copolymers) containing ferrocene groups and their application as lithium-ion battery cathode materials, and the resulting lithium-ion battery. Background technique [0002] With the rapid development of the global economy, human beings are faced with many problems in the development process, among which energy is the basis for human survival and the source of world economic growth. Therefore, energy issues have become a topic of discussion worldwide in the 21st century. hot topic. Electric energy shows its superiority due to its clean, safe, and convenient features. The rapid development of portable electronic devices forces chemical power sources to develop towards light, small, and long-lasting types. This has also given birth to the lithium-ion battery industry with high energy density, light weight, and long cycle ...
