Embodiment Construction
[0031] According to a non-limiting embodiment of the present invention, a method for preparing a battery positive electrode nano-composite material is provided, including the following steps.
[0032] Step S1: Prepare 8 parts of magnesium chlorate, 50 parts of manganese dioxide, 8 parts of activated carbon, 3 parts of acetylene black and 10 parts of multi-walled carbon nanotubes with 20 to 40 layers in parts by weight;
[0033] Step S2: adding the prepared magnesium chlorate to deionized water to prepare a 60% magnesium chlorate solution;
[0034] Step S3: Put the prepared manganese dioxide, activated carbon, acetylene black, and multi-walled carbon nanotubes into a mixer and mix for 2 hours;
[0035]Step S4: adding the magnesium chlorate solution to the mixed powder in step (3), and continuing to stir in a mixer for 3.5 hours to fully disperse to obtain a uniformly mixed synthetic material;
[0036] Step S5: thinly spread the synthetic material in a container, put it into an...

The invention discloses a preparation method for a battery anode nano synthetic material and a magnesium-based inert cell. The preparation method comprises the following steps: preparing the following components in parts by weight: 3-12 parts of magnesium chlorate, 30-70 parts of manganese dioxide, 3-12 parts of activated carbon, 1-5 parts of acetylene black and 1-15 parts of multi-wall layer carbon nanotubes; putting prepared magnesium chlorate into deionized water so as to prepare a magnesium chlorate solution; mixing and stirring prepared manganese dioxide, activated carbon, acetylene black and the multi-wall layer carbon nanotubes for 1-2 hours; putting the magnesium chlorate solution into mixed powder, stirring for 3-4 hours, and performing sufficient dispersion so as to obtain a uniformly mixed synthetic material; and drying the synthetic material for 1-2 hours at 80-95 DEG C, thereby obtaining the nano synthetic material for the anode of the magnesium-based inert cell. The dried synthetic material can be further grinded, and then a nano synthetic material of which the particle size is 380-450 meshes is prepared.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a magnesium-based battery. Background technique [0002] With the increase of people's consumption and the acceleration of the industrialization process, the global demand for energy is increasing day by day. The large consumption of non-renewable energy has caused its reserves to decrease sharply, and the problems of environmental pollution and energy shortage have become increasingly prominent. Research and development of cleaner and more efficient green energy has become an important means for various countries to solve energy, environmental, social and economic problems. Magnesium-air batteries use oxygen in the air as the positive electrode electrochemically active material, and metal magnesium as the negative electrode electrochemically active material, which has the characteristics of high energy density, abundant resources, and green and pollution-free reactive material...
