Problems solved by technology

[0003] In 2007, Suga et al. used two different free radical polymers to assemble an all-organic battery and speculated on the charging and discharging mechanism of the battery. Unfortunately, this research did not make a breakthrough.
The types of organic polymers studied so far are limited, and the relationship between their structure and electrochemical performance needs to be further explored. The capacity of polymers in the data is not high, and the voltage of positive and negative electrode materials is not ideal, so the combined full battery has Low capacity, low working voltage, low energy density, etc.

Embodiment 1

[0035] Embodiment 1, the present embodiment synthesizes Schiff base polymer, and the steps are as follows:

[0036] (1) Synthesize 4,4',4"-trialdehyde substituted triphenylamine according to the prior art, the synthetic route is as follows:

[0037]

[0038] Specifically include the following steps:

[0039] (1.1) Preparation of 4,4'-dialdehyde-substituted triphenylamine

[0040] Weigh 10.001g of triphenylamine into a 250mL two-necked flask, then add 41.0mL of DMF, and stir. The flask was placed in an ice-water bath (guaranteed at 0°C), protected by argon. Add 37.5 mL of POCl into the constant pressure separatory funnel with a syringe 3 , open the constant pressure funnel, control the flow rate, POCl 3 Slowly added dropwise to a two-necked flask, and stirred for 1 hour.

[0041] The oil change pan was heated to 105°C and stirred for 4 hours. After cooling to room temperature, it was slowly added to ice water with stirring, the system was black, and a brown solid was p...

Embodiment 2

[0071] Example 2: In this example, the Schiff base polymer prepared in Example 1 is used as the negative electrode material of the battery, and polytriphenylamine is used as the positive electrode material to prepare a high-voltage organic polymer full battery with a voltage of 3V. The steps are as follows:

[0072] (1) According to the existing technology, polytriphenylamine is synthesized.

[0073] To match the negative electrode, polytriphenylamine was used as the positive electrode. Polytriphenylamine was synthesized with reference to the method in the literature. The specific process was: 0.025mol (~6.1g) triphenylamine was dissolved in 100mL of anhydrous chloroform; under the protection of argon, the total amount of 0.1mol (~16.22 g) anhydrous ferric chloride, add once every hour; and continue to react for 2 hours. The reaction mixture was poured into methanol and the product precipitated out. The crude product was dissolved in chloroform, filtered, the filtrate was co...

Abstract

The invention discloses a Schiff alkali polymer and a synthesis method and an application thereof. A Schiff alkali polymer electrode material with a three-dimensional conjugate structure has highly delocalized phi electrons, relatively low equilibrium electrod potential (0.7V vs.Li<+> / Li) and excellent electrochemical oxidation-reduction reversibility and stability. With Schiff alkali as a cathode and poly-triphenylamine (PTPA) as an anode, an organic polymer total battery is assembled after capacity matching; the battery voltage can be up to 3V; and the Schiff alkali polymer has relatively good reversibility.

Description

technical field [0001] The present invention relates to a kind of Schiff base polymer and its preparation method and application, described Schiff base polymer has three-dimensional conjugated structure, lower equilibrium electrode potential (0.7V vs. Li + / Li) and excellent redox reversibility. Background technique [0002] The research on polymers as electrode materials began in 1979. Most of them use polymers as the positive electrode of the battery, while metal lithium is used for the negative electrode of the battery. Since the emergence of all-organic batteries in 1984, Farrington has studied polyacetylene as both the positive and negative electrodes of the battery. However, due to the instability and poor performance of polyacetylene in the air, it has great problems in full battery assembly. It was reported in 1986 that Mohammadi et al. studied an all-organic battery with polypyrrole as the positive and negative electrodes, but because polypyrrole does not have n-d...
