Description

Technical Field

[0001] The invention relates to a battery element, in particular to a high-performance carbon battery and a production process thereof. Background Art

[0002] Carbon battery is the full name of neutral zinc-manganese dioxide dry battery (zinc-manganese dry battery). It is a primary battery among chemical power sources and a disposable battery. The working principle of carbon battery is to convert the chemical energy of manganese dioxide and zinc into electrical energy through chemical reaction. During the discharge process, the zinc at the negative electrode undergoes oxidation reaction, and the manganese dioxide at the positive electrode combines with electrons. Carbon battery is mainly used for low power consumption. Due to its low price and safe and reliable use, it is widely used in daily household items, such as flashlights, remote controls, etc.

[0003] Carbon batteries have been developed since the mid-19th century and have always played an important role in the field of energy storage. With the development of science and technology, carbon batteries are currently mainly used in some low-power, low-current devices. The production cost of carbon batteries is low, and the production technology is relatively mature, which is suitable for cost-sensitive application scenarios. In addition, carbon batteries rely on the electrochemical properties of materials to discharge, have good structural stability, and have relatively mature model development. They have low current and can maintain power for a long time, and have good safety, so they have special industrial value.

[0004] In order to expand the applicable scenarios of carbon batteries, it is often necessary to increase the voltage and current of carbon batteries. The methods that can be used include using composite positive electrode materials, changing the battery structure and adjusting the composition of the electrolyte. In carbon batteries, the electrolyte transfers ions, allowing the battery to generate current. However, carbon battery electrolytes are often non-flowing, with relatively high internal resistance and low output current, which limits their application in high-power demand equipment. Adjusting the electrolyte composition to improve ion transfer efficiency has become an important strategy to improve battery voltage and current. However, improving ion transfer efficiency may often lead to increased battery gas production and poor structural stability. Therefore, it is particularly necessary to develop a carbon battery with high voltage, low resistance and low gas production. Summary of the invention

[0045]

[0046] Note: The amount of polyacrylamide added is based on the mass of polyacrylamide.

[0047] Effect Example 1 Discharge and stability test.

[0048] The open circuit voltage (V) and internal resistance (mΩ) of the dry cells of Examples 1-5 were measured using a BS-VR3 battery internal resistance tester. The open circuit voltage measurement results are shown in Table 2.

[0049]

The addition of polyquaternary ammonium salt does not significantly weaken the battery performance. Weak acid and alkaline salts (ammonium acetate and polyacrylamide) are not conducive to internal resistance.

[0053]

[0054] The dry cell battery uses a zinc cylinder shell. Because the electrolyte is an acidic electrolyte, there is a defect of gas production. Storage at room temperature causes the battery efficiency to decrease. As shown in Table 3 above, the battery of the present invention has a lower gas production and a lower volume expansion coefficient. The addition of the polymer further improves the stability of the dry cell battery.

[0067] In this application, in order to explore the mechanism of the influence of polymers on the stability of dry batteries, the inventors used a large number of commercially available polymer materials, such as plastics, to dope dry batteries, but failed to obtain battery materials with good stability. The doping of plastics instead affected the mechanical properties and resistance of the battery. It is speculated that the conductivity and adhesion of plastics are poor, which is insufficient to provide the mass transfer electrochemical environment required by dry batteries.

[0068] Based on the above research, the inventors further studied adhesive and conductive materials, and speculated that polymers with strong adhesiveness and conductivity may help the stability of dry batteries. The polymer monomers of the polymer materials used in Comparative Examples 1-4 are bisphenol A monomers, which have improved conductivity. The corresponding monomers are shown in Table 4 below.

[0069]

[0070] The attenuation of the dry cell obtained was tested with reference to the above embodiment, and the discharge time of the obtained battery was tested at room temperature for 260 days in parallel. The discharge time was detected, and the results are shown in Table 5.

[0071]

[0072] Bisphenol A polymers have been used to improve battery performance due to their high conductivity. However, according to the above test results, improving the conductivity and adhesion of the material cannot effectively improve the stability of dry batteries. During storage, dry batteries will have a large power loss. Taking experimental errors into account, polybisphenol compounds cannot effectively improve the stability of battery materials.

[0073] The inventor accidentally discovered that adding a small amount of water-soluble ammonium salt polymer to a dry cell battery may help stabilize the structure of the dry cell battery, improve battery stability, and will not affect the battery voltage and current.
