Explanation of terms for commonly used batteries

Carbon-zinc battery is also called carbon-zinc dry battery, carbon battery, carbon battery, the outer shell is made of zinc. It can be used as a battery container or as the negative electrode of the battery. The carbon-zinc battery is an extension of the liquid Leclanche battery. Conventional or conventional ammonium chloride electrolyte; the battery is a typical carbon-zinc battery with zinc chloride as the electrolyte, which is an improved version of the cheap battery commonly used. The positive electrode of the battery is mainly composed of powdered manganese dioxide and carbon. The electrolyte is a paste of zinc chloride and ammonium chloride dissolved in water. Carbon batteries and zinc batteries are the cheapest of the battery types, which makes them the first choice of many manufacturers who usually distribute them in the equipment they sell. Zinc-carbon batteries can be used in low-power devices such as remote controls, flashlights, toys, or transistor radios. This battery positive carbon rod and manganese dioxide mixed carbon is only responsible for the leadership, does not participate in the reaction, the anode practice participates in the recovery response and manganese dioxide supplies active power in manganese, therefore, it is also called zinc manganese battery, zinc manganese battery, zinc two Manganese oxide batteries, also known as manganese dry batteries. The voltage of the carbon-zinc battery is 1.5V. Zinc-air battery Zinc-air battery is a special kind of battery. The negative electrode is made of zinc alloy. The positive data is the oxygen in the air. It is generally kept sealed during storage, so there is basically no self-discharge. Also called zinc-oxygen battery, sometimes called zinc-air battery. Because the zinc-air battery contains a high concentration of electrolyte (potassium hydroxide is strongly alkaline and corrosive), once a leak occurs, it will corrode the adjacent components of the battery, and this corrosion may be unmodifiable and fatal. Due to the holes in the battery, the storage time after the battery is activated and used is very short, so the zinc-air battery is more prone to battery leakage. When using zinc-air batteries, replace the used batteries in time, check the battery condition frequently, and remove the batteries when they are not in use for a long time. The voltage of the zinc-air battery is 1.4v. Lead-acid battery Lead-acid battery, also known as lead battery, is a kind of battery. The first electrode is made of lead, and the electrolyte is a kind of battery in sulfuric acid solution. Generally divided into two types: open battery and valve-regulated battery. The former should be protected by acid injection in time, while the latter is an unprotected battery. The principle of the battery is through the mutual conversion of chemical energy and DC electrical energy, and after discharge, it is restored by charging, and then it can achieve the effect of repeated use. The voltage of a lead-acid battery is 2V. Gel batteries Gel batteries are divided into lead-acid batteries. The simplest method is to add a gelling agent to sulfuric acid to make the sulfuric acid electro-liquid colloidal. Electro-hydraulic gel batteries are generally called gel batteries. Electro-hydraulic gelation. For example, non-curing hydrocolloids belong to colloidal batteries in terms of electrochemical classification structure and characteristics. And if the polymer material is attached to the grid, commonly known as the ceramic grid, it can also be seen as using the characteristics of the gel battery. The differences between gel batteries and traditional lead-acid batteries range from the preliminary understanding of electrolyte bonding to further research on the electrochemical performance of the electrolyte basic structure, as well as the application and promotion of grids and active materials. The discharge curve of the gel battery is flat, the energy is more than 20% larger than that of the conventional lead-acid battery, and the life span is generally about 1 times longer than that of the conventional lead-acid battery, and the high temperature and low temperature characteristics are much better. The voltage of the gel battery is 2V. Nickel-cadmium batteries use nickel hydroxide (NiOH) and metallic cadmium (Cd) as chemical substances to generate electricity. Compared with other types of batteries, nickel-cadmium batteries have the following advantages: small components, high charging power, small terminal voltage changes during discharge, small internal resistance, and low requirements for the charging environment. The defects of nickel-cadmium batteries are the recall effect of cadmium and heavy metal pollution. The voltage of the nickel-cadmium battery is 1.2v. Nickel Metal Hydride (NiMH) batteries are an improvement of nickel-cadmium batteries, which replace cadmium with a hydrogen-absorbing metal. Compared with nickel-cadmium batteries of the same price, it offers a higher capacity, the recall effect is not so obvious, and the environmental pollution is lower (does not contain toxic cadmium). Recycled electricity is better than lithium batteries, which are known as the most environmentally friendly batteries. But compared with lithium batteries, it has a higher recall effect. The old Ni-MH battery has a high self-discharge response, while the new Ni-MH battery has a moderately low self-discharge (about the same as the base electricity) and can work at low temperatures (-20°C). The output current of nickel-hydrogen batteries is larger than that of carbon-zinc batteries or alkaline batteries, and is more suitable for high-power products. In some specific types of products, the output current is even greater than that of nickel-cadmium batteries. At present, the general capacity of Ni-MH batteries has always been higher than that of alkaline batteries. Taking AA batteries as an example, Ni-MH batteries have a display capacity of up to 2900mAh (milliampere-hour, widely known as mAhmilliampere-hour in mainland my country), and Alkaline batteries ~ 2100mAh, of course, are also much higher than 1100mAh Ni-Cd batteries, but they are still not competent for lithium batteries. Alkaline batteries will leak all small corrosive and harmful liquids (which may be harmful to the human body or damage the equipment using the battery) when they are not used for a long time, while lithium batteries may burn or explode when they are not used. Ni-MH batteries are relatively safe batteries. The voltage of the Ni-MH battery is 1.2v. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
