specific Embodiment approach 1

[0022] Specific implementation mode 1: This implementation mode is a preparation method of a portable clean energy micro-storage device, which is carried out through the following steps:

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

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

specific Embodiment approach 2

[0030] Embodiment 2: This embodiment differs from Embodiment 1 in that in Step 1, it is placed in a dilute hydrochloric acid solution with a concentration of 0.08 mol / L and ultrasonically cleaned for 40 minutes. Others are the same as the first embodiment.

specific Embodiment approach 3

[0031] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that: in step 2, the temperature is 100° C. for 1 hour. Others are the same as those in Embodiment 1 or 2.

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 people's continuous demand for energy and increasing environmental pollution, the development of high-energy storage, recyclable, non-environmental pollution, and portable miniature energy storage devices 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, yet the power density is less than that of supercapacitors. At present, people's research is how to reduce the volume expansion, i...
