Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] refer to figure 1 , which characterizes the Si-coated Fe 3 o 4 TEM observations of nanoparticles, Si-coated Fe 3 o 4 The particle size of nanoparticles is below 200nm.

[0020] The invention provides a novel liquid electrolyte with controllable properties based on magnetorheological technology, including: silicon-coated Fe 3 o 4 Nanoparticles, EMITFSI, and nanosilicon particles.

[0021] Wherein, taking the quality of EMITFSI as a benchmark, that is, recording EMITFSI as 100wt%, the prepared silicon-coated Fe 3 o 4 10% of nano particles, the proportion of nano silicon particles is between 0.8% and 1.2%. All components are dispersed in proportion by ultrasonic waves to form a uniformly dispersed and stable suspension liquid, which is the novel liquid electrolyte with controllable properties based on magnetorheological technology ...

Abstract

The invention discloses a magnetorheological technology based novel liquid electrolyte with controllable properties. The liquid electrolyte includes silicon-coated Fe3O4 nanoparticles, EMITFSI and nano silicon particles; and the mass of the EMITFSI is taken as reference, the EMITFSI is marked as 100 wt%, the content of the silicon-coated Fe3O4 nanoparticles is 2-20 wt%, and the content of the nanosilicon particles is 0.2-1.2 wt%. Ionic liquid magnetorheological fluid can be suspended stably, has good electrical conductivity and can be applied to electric equipment such as supercapacitors; andthe liquid electrolyte is simple in preparation, stably suspended ferromagnetic particles can be introduced into a material system without obviously affecting the electrical conductivity of originalliquid electrolytes, namely, a control source with rapid response can be introduced to stably change the property of the novel liquid electrolyte in real time, so that leakage proof mechanism and safety characteristics can be provided for the electric equipment adopting the novel material.

Description

technical field [0001] The invention relates to the field of liquid electrolytes, in particular to a novel liquid electrolyte with controllable properties based on magnetorheological technology. Background technique [0002] As a sustainable energy source, high-performance liquid electrolytes are widely used in high-tech fields such as aerospace, electronic equipment, and electric vehicles. Its safety concerns are also of concern, however, with leaks of liquid electrolytes, overheating and catastrophic incidents under crash conditions often making headlines. [0003] Most of the currently widely used liquid electrolytes are flammable and volatile, and are prone to danger once exposed to the air environment. Ionic liquid is a liquid material composed entirely of positive and negative ions. It maintains a stable liquid shape in a wide temperature range from tens of degrees below zero to hundreds of degrees above zero. It is non-volatile, non-flammable and has good properties ...
