Description
Technical Field
The invention belongs to the technical field of batteries, and particularly relates to a tin-manganese secondary battery.
Background
Since the twenty-first century, the world's crude oil supply has been increasingly tightened by the increasing global energy demand, and people are also increasingly receiving attention from environmental problems caused by the use of fossil fuels, such as global warming and more severe haze weather. However, due to the intermittent, discontinuous and unstable characteristics of renewable energy sources (such as wind energy, solar energy, tidal energy and the like), the difficulty of large-scale integration of the renewable energy sources into the power grid is increased, and in order to improve the utilization rate of the renewable energy sources, the development of a large-scale energy storage battery system is one of effective approaches.
Battery systems expected to be applied to large-scale energy storage can be simply classified into nonaqueous electrolyte-based battery systems and aqueous electrolyte-based battery systems. For example, conventional lithium ion batteries employ an anhydrous organic solution as an electrolyte, and exhibit a high operating voltage. However, highly toxic and flammable organic electrolytes pose a risk of explosion of the battery, and this problem is more prominent in the field of large-scale energy storage. The high-temperature sodium-sulfur battery adopts liquid molten electrodes, does not contain aqueous electrolyte, and shows high working voltage and energy density, but combustible metal sodium electrodes and sulfur electrodes still have the danger of fire and explosion at high temperature, which has been proved by accidents previously. In addition, the working safety of the battery can be greatly improved by adopting the aqueous electrolyte, and the main reason is that the aqueous electrolyte is not combustible. Therefore, lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, all-vanadium redox flow batteries, zinc-bromine redox flow batteries, recently developed water-based lithium ion/sodium ion batteries and the like based on aqueous electrolyte are expected to be more widely applied to the field of large-scale energy storage. However, the large-scale use of the above-described water-based battery systems still faces these many challenges and bottleneck problems. Firstly, lead-acid batteries, nickel-cadmium vanadium flow batteries, zinc-bromine flow batteries and the like all contain environmentally unfriendly toxic elements, such as lead ions, cadmium ions and elemental bromine; secondly, the electrode reactions of aqueous lithium/sodium ion batteries and lead-acid batteries involve ion intercalation and deintercalation and conversion of crystal structures, exhibiting limited cycle life and power density; finally, the existing commercial vanadium redox flow battery and zinc-bromine redox flow battery must adopt expensive and fluorine-containing ion exchange membranes as battery diaphragms, which increases the cost and simultaneously aggravates the environmental pollution.
In view of the above problems, the present invention proposes a tin-manganese aqueous battery system. The positive pole reaction is bivalent manganese ion (Mn)2 +) Trivalent manganese ion (Mn)3+) The negative electrode reaction is tin (Sn)/tin ion (Sn)2+) In betweenAnd (3) performing a depreciation reaction, and taking an aqueous solution containing divalent tin ions and divalent manganese ions as an electrolyte. Compared with the existing battery system, the battery system has the following advantages: firstly, toxic elements such as lead (Pb), cadmium (Cd), vanadium (V) and the like are not involved in electrode reaction; secondly, toxic and combustible organic electrolyte is not adopted; thirdly, the electrode reaction is not controlled by the diffusion and phase inversion of ions in the electrode crystal structure, and the ultrahigh power characteristic is shown; fourthly, compared with the traditional flow battery which adopts an expensive ion exchange membrane, the battery system adopts a porous PBI membrane, so that the cost is reduced.
