specific Embodiment approach 1

[0022] Specific embodiment 1: This embodiment is a method for preparing a portable clean energy micro storage device through the following steps:

[0023] 1. Cleaning of the current collector: Place the current collector in water for ultrasonic cleaning for 5 min to 120 min, then place it in ethanol for ultrasonic cleaning for 5 min to 300 min, and finally place it in a dilute hydrochloric acid solution with a concentration of 0.01 mol / L to 6 mol / L. 5min~200min, get clean current collector;

[0024] 2. Mix the cobalt nitrate solution with the concentration of 0.0001mol / L~1mol / L and the urea solution with the concentration of 0.0001mol / L~1mol / L and stir for 5min~720min to obtain the mixed solution A. The clean solution obtained in step 1 The current collector is immersed in the mixed solution A, and then transferred to the reactor. After heating for 0.5h to 72h at a temperature of 90°C to 200°C, the product is taken out of the reactor, and the product is washed with water 3 to 5 tim...

specific Embodiment approach 2

[0030] Specific embodiment two: this embodiment is different from specific embodiment one in that in step one, it is ultrasonically cleaned in a dilute hydrochloric acid solution with a concentration of 0.08 mol / L for 40 minutes. Others are the same as the first embodiment.

specific Embodiment approach 3

[0031] Specific embodiment three: This embodiment is different from specific embodiment one or two in that in step two, heating is performed at a temperature of 100° C. for 1 hour. Others are the same as the first or second embodiment.

Abstract

The invention provides a preparation method for a portable minitype clean-energy storage device, relates to a preparation method for the portable minitype clean-energy storage device, and is to solve a problem that the existing lithium ion battery and supercapacitor materials cannot simultaneously achieve low cost, stability and excellent rate capability. The preparation method comprises the steps: 1, cleaning a current collector; 2, preparing a current collector, wherein cobalt oxide grows on the surface of the current collector; 3, preparing a current collector, wherein the cobalt oxide and cobalt molybdate grow on the surface of the current collector; 4, mixing PVA and KOH, and putting the mixture into water to stir, thereby obtaining a mixed solution C; 5, arranging a fiber resin diaphragm between two current collectors, on the surfaces of which the cobalt oxide and the cobalt molybdate grow, to obtain a component; immersing the component into the mixed solution C, drying the immersed component, and coating the exterior of the dried component with a metal housing, thereby obtaining the portable minitype clean-energy storage device. The preparation method for the portable minitype clean-energy storage device can provide clean energy for electrochromic smart windows, mobile phones, electric vehicles and the like.

Description

Technical field [0001] The invention relates to a preparation method of a portable clean energy micro storage device. Background technique [0002] With the continuous demand for energy and the increasing environmental pollution, the development of high-energy storage, recyclable, non-environmental pollution, and portable micro-energy storage equipment will become a research hotspot. For the development and utilization of energy, people currently use wind energy, water energy, solar energy, tidal energy, electric energy, etc. However, compared with other energy sources, electric energy can be used in any occasion without the restriction of the external environment. Lithium-ion batteries and supercapacitors have their own advantages and disadvantages as electrical energy storage devices. Lithium-ion batteries can provide high energy density, but the power density is less than supercapacitors. At present, people's research is how to reduce the volume expansion, increase the spec...
