What kind of battery is a green battery?

At present, metal hydride nickel batteries, lithium-ion batteries, mercury-free alkaline zinc-manganese primary batteries and rechargeable batteries that have been widely used, as well as lithium or lithium-ion plastic batteries and fuel power batteries that are being researched and developed, belong to This category. In addition, solar cells (also known as photovoltaic power generation) that have been widely used and use solar energy for photoelectric conversion can also be included in this category. Nickel-metal hydride storage battery (Ni-MH) and nickel-cadmium storage battery (Ni-Cd) have the same working voltage (1.2V), but due to the use of rare earth alloy or TiNi alloy hydrogen storage material as the negative electrode active material, The replacement of the carcinogen cadmium not only makes this new type of battery a green and environmentally friendly battery, but also increases the specific energy of the battery by nearly 40%, reaching 60-80Wh/kg and 210-240Wh/L. This battery was gradually industrialized in the early 1990s and was first used in mobile phone batteries. Although its dominant position in mobile phones has been gradually replaced by lithium-ion batteries, its market share in European and American mobile phone applications is still around 50%. Lithium-ion battery Li-ion battery (Li-ion) is composed of carbon that can intercalate and deintercalate lithium ions as negative electrode, metal oxide that can reversibly intercalate lithium as positive electrode (LiCoO2, LiNiO2 or LiMn2O4) and organic electrolyte. Its working voltage It is 3.6V, so a lithium-ion battery is equivalent to three nickel-cadmium or nickel-metal hydride batteries. Therefore, the specific energy of this battery can exceed 100Wh/kg and 280Wh/L, which greatly exceeds the specific energy of metal hydride nickel batteries. In view of the above advantages, in just a few years from 1993 to 2000, its production and usage have increased at an extremely high rate. Alkaline zinc-manganese dry batteries Alkaline zinc-manganese dry batteries (alkaline) have higher capacity than ordinary dry batteries of the same size, and have the ability to discharge large currents. In recent years, mercury-free zinc powder has been applied, so this battery has become a green battery and the mainstream product in the primary battery. At present, the alkaline zinc manganese dry battery is still the most used power source for BP machines. At the same time, countries around the world are also concerned about the rechargeability of this battery. A company in the United States has launched a rechargeable alkaline manganese battery, and the application of the product is slowly increasing. This battery maintains the discharge characteristics of the original battery, and can be recharged and used tens to hundreds of times (deep charge-discharge cycle life is about 25 times). Lithium Plastic Battery Lithium Plastic Battery (LIP) is a new type of battery with lithium metal as the negative electrode and conductive polymer as the electrolyte. Its specific energy has reached 170Wh/kg and 350Wh/L. Lithium-ion plastic batteries store the organic electrolyte in the current lithium-ion battery in a polymer film, or use conductive polymers as the electrolyte, so that there is no free electrolyte in the battery. The battery can be heat-pressed and packaged with an aluminum-plastic composite film, and has the characteristics of light weight, shape can be changed arbitrarily, and safety is better. Fuel power cell Fuel power cell (FC) is a device that uses fuel (such as hydrogen or fuel) and oxidizer (such as pure oxygen or oxygen in the air) to directly and continuously generate electricity. Because it avoids the limitations of the Carnot cycle, This kind of power generation device not only has high efficiency (the conversion efficiency of electrochemical reaction can be as high as 40% or more), and no polluting gas is discharged, so it is an efficient and clean power generation method in the future. Many companies at home and abroad are committed to the development of PEM fuel power cells suitable for mobile phones and notebook computers. Once they are put into use, their economic benefits will be great. Sealed lead-acid batteries are a type of lead-acid batteries. The following new green battery skills and related industries are particularly quick to develop. 1. Hydrogen storage materials and metal hydride nickel storage battery nickel-hydrogen battery. 2. Lithium ion embedded materials and liquid electrolyte lithium ion batteries. 3. Polymer electrolyte lithium battery or lithium ion battery. 4. Zinc-air battery and fuel power battery.
