What are the important uses of batteries?

The important uses of batteries are: (1) Battery (Battery) refers to a cup, tank or other container or part of the space of a composite container that contains electrolyte solution and metal electrodes to generate current. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The important performance parameters of the battery are electromotive force, capacity, specific energy and resistance. (2) Using the battery as an energy source can obtain a current with stable voltage, stable current, stable power supply for a long time, and little influence from the outside world. The battery has a simple structure, is convenient to carry, and is easy to charge and discharge, and is not affected by external weather. It has stable and reliable performance due to the influence of temperature and temperature. It plays an important role in all aspects of modern social life and occupies a large proportion of electric energy use. (3) Alkaline batteries use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. Its characteristics are superior to those of carbon-zinc batteries, with large capacity. Taking Jin-top alkaline batteries as an example, they have an average of 5 times more power than carbon-zinc batteries (the power multiple will vary depending on the electrical product), good preservation, and leakage resistance. Good liquidity, good temperature resistance, small voltage change, stable voltage can be obtained, and high-efficiency discharge can be achieved under high current, so both large and small current devices are suitable for use. (4) The carbon-zinc battery uses manganese dioxide as the positive electrode, zinc as the negative electrode for the reaction, ammonium chloride and zinc chloride aqueous solution as the electrolyte, its characteristics are not good voltage stability, temperature characteristics are not good, at 0 ℃ Significant deterioration in the following cases. Regarding some electronic equipment that requires voltage stability, small size, high output, and high energy density, carbon-zinc batteries are not applicable, and are only applicable to lamps, lighting equipment, toys, etc. (5) The functional difference between alkaline batteries and carbon-zinc batteries is: carbon-zinc batteries, alkaline batteries, electric capacity, small and large. High rate discharge, not suitable, suitable. The storage life is short, and the shelf life is 2 years. At normal room temperature (21 degrees Celsius), 15% of electricity is lost every year. The storage life is long, and the shelf life is 5 years. At normal room temperature, the power loss is 5% in the first year and 2% every year thereafter. Temperature resistance is poor, below 0 degrees Celsius, the power is quickly lost. Good temperature resistance, it can work between -20°C and 50°C. The purpose is narrow, only suitable for low-current electrical appliances, such as clocks, water heaters, etc. It has a wide range of uses, and it is suitable for electric appliances of large and small currents. The electronic dictionary and cd player are the same as those with high current. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
