Embodiment 1

[0029] 1. Uniformly mixed 60 mg of κ-kara gel and 40 mg konjac gum, then dispersed in 10 g of deionized water, and the deionized water resistance rate was 18.4 Ω, and dispersion was obtained;

[0030] 2. Stirring the dispersion at 80 ° C water bath for 30 min to give a concentration of 1% by weight of κ-kara gel and konjac gum.

[0031] figure 1 In the infrared spectrogram of the kappa-kara gel and konjac glue in Example 1. Among them, (a) kg is κ-kara gel, (b) kcg is konjac gum, (c) N-KCG-kg is kappa-kara gel and konjac glue. From figure 1 It can be seen that the interaction between κ-kara gel and konjac glue is studied by FTIR spectroscopy. When interaction occurs, the Summit allocated to a particular functional group is moved to a higher or lower wave number, or a new peak. Konjac glue in 3408cm -1 The absorption peak represents O-H telescopic vibration, 2926cm -1 The absorption peaks at the point represents the telescopic vibration of C-H, at 1724cm -1The absorption peak at t...

[0036] 1. Mix 50 mg of kappa-kara gel and 50 mg konjac gel; then dispersed in 12.5 g of deionized water, and the deionized water resistance rate was 18.4 Ω, and dispersion was obtained;

[0037] 2. Put the dispersion at a water bath of 90 ° C for 30 min to give a concentration of 0.8 wt% κ-kara gel and konjac gum.

Embodiment 3

[0039] 1. Mix the 25 mg of κ-kara gel and 75 mg of konjac gum, then dispersed in 6.25 g of deionized water, and the deionized water resistance rate was 18.4 Ω, and dispersion was obtained;

[0040] 2. Stirring the dispersion at 90 ° C water bath for 30 min to give a concentration of 1.6% by weight of the kappa-kara gel and konjac glue solution solution.

Abstract

The invention belongs to the technical field of binder synthesis and electrochemistry, and discloses compound gum of carrageenan and konjac gum as well as a preparation method and application of the compound gum. The compound gum is prepared by the following steps: uniformly mixing kappa-carrageenan and konjac gum, performing dissolving in deionized water, and performing stirring to form a dispersion liquid; and placing the dispersion liquid in a water bath at 60-90 DEG C, and performing heating and stirring to form a colloidal solution. According to the compound gum disclosed by the invention, functional groups of the kappa-carrageenan and the konjac gum interact under heating and stirring conditions, so that biomass polymers with a three-dimensional network are formed. The biomass polymers can generate a synergistic effect to generate characteristics which are not possessed by each monomer adhesive so as to make up for respective defects. The compound gum solves the problem of insufficient bonding capacity or poor mechanical property when a low-cost water-soluble natural polymer material is used as a binder of a silicon negative electrode of a lithium ion battery, and the compound gum is simple in synthesis process, meets the requirements of green chemistry, has low requirements on equipment and is beneficial to marketization popularization.

Description

Technical field [0001] The present invention belongs to binder synthesis and electrochemical techniques, and more particularly to a kappa-kara gel and konjac glue, a compounding rubber and preparation methods and applications thereof. Background technique [0002] In order to adapt to rapid growth of renewable energy, the development of large-scale energy storage systems in low cost, high security and high energy density has caused a strong interest in people. Lithium-ion batteries have advantages such as high energy density and long cycle life, and is considered to be the most promising energy storage device, which is now widely used in portable electronic devices, such as smartphones, intelligent wear devices and computers. However, it is necessary to advance its large-scale applications in electric vehicles and smart grids, must achieve excellent energy density, long service life, and low-cost economic cost requirements. Silicon has the advantage of tetracy more than ten times...
