Preparation and application of lithium batteries, nickel-hydrogen batteries and nickel-cadmium batteries

Abstract

With the progress of the times and the development of technology, there are more and more types of batteries, and the application of batteries in life is more and more extensive. In recent years, due to the promotion and popularity of electric vehicles, lithium batteries, nickel-cadmium batteries, and nickel-metal hydride batteries have gradually moved from the laboratory to everyone's life. This paper discusses the three types of batteries used today and the preparation methods, advantages and disadvantages, applications, and prospects of these three types of batteries. Lithium battery is mainly composed of lithium, with more active chemical properties, and has become the mainstream of the world today; the positive active ingredient of the nickel-cadmium battery is predominantly made of nickel, the negative active ingredient is predominantly made of cadmium, an alkaline battery, the current common battery device, commonly used in small equipment; nickel-hydrogen batteries are improved from nickel-cadmium batteries, which can absorb hydrogen metal instead of cadmium, compared to lithium batteries are safer It is safer than lithium battery. Batteries have positive and negative poles, and this paper also describes the manufacturing methods of positive and negative poles of the three types of batteries. The widespread application and immense market demand for lithium-ion batteries, Nickel-hydrogen (NiMH) batteries, and Nickel-cadmium (NiCd) batteries have significant implications for scientific progress and economic prosperity. Therefore, research efforts directed toward high-performance lithium-ion, NiMH, and NiCd batteries hold tremendous scientific and economic value.
