Types of lithium batteries

Types of lithium batteries: 1. Lithium cobalt oxide batteries: The major feature of the whole configuration process is that when the battery is fully charged, there are still many lithium batteries with positive levels. In other words, there is not a large amount of lithium batteries on the negative stage adhering to the positive stage, but in the case of overcharging, unnecessary lithium batteries on the positive stage will still sneak into the negative stage, because it cannot be completely accommodated. , There will be metallic lithium on the negative stage. Because this kind of metallic lithium is a dendritic structure crystal, it is called a dendrite. Once a dendrite appears, it will give a chance to penetrate the gap. Partition wall puncture will cause internal short-circuit failure. Because the key component of the lithium battery electrolyte is carbon acid grease, the lightning and melting point are very low, so at high temperatures, it will ignite or even explode. It is relatively simple to manipulate the structure of lithium dendrites in small-volume lithium batteries. Therefore, lithium cobalt oxide batteries are currently only used in small-volume rechargeable batteries such as portable electronic products, and cannot be used to power lithium batteries. 2. Polymer lithium battery: Compared with kinetic energy, the basic theory that can be used in practice activities has a very large development. It is related to lithium cobalt oxide batteries, which can better fully exert its high-capacity effect, but at this stage of polymerization Material lithium batteries also use lithium cobalt oxide batteries and organic chemical lithium battery electrolyte, so the safety factor problem has not been completely solved. In application, assuming a short-circuit fault occurs, the rechargeable battery will cause excessive current. The lithium battery electrolyte of the polymer material lithium battery is a colloidal solution, which is not easy to leak, which eliminates the probability of liquid leakage, but it will ignite more violently. Therefore, a fire is a larger polymer material lithium battery. risk. 3. Lithium manganese oxide battery: The data information of lithium manganese oxide battery has certain advantages. It can ensure that the positive lithium battery can be completely inserted into the negative carbon hole under the condition of full charge, unlike cobalt acid. Like lithium batteries, there will be a certain amount of content, which prevents dendrites from the source. This is all theoretically known. In fact, it is assumed that the purpose of using lithium manganese oxide batteries is to better enable rechargeable batteries to take on a large external force. Maybe the rechargeable battery is shoddy in the whole process or it may be the rechargeable battery in the whole process of the battery charging cycle system The rapid fitness exercise of lithium battery appeared in an instant. Dendrites appear when the negative stage does not immediately completely digest and absorb the lithium battery. Carry out the test at the original factory of the rechargeable battery to ensure the effectiveness of the result. Generally speaking, lithium manganese oxide batteries that meet the system test standards are generally not prone to safe processing accidents. Because the stable structure of lithium manganate battery promotes its air oxidation performance to improve, the lithium cobalt oxide battery is much lower, so even if the external short-circuit failure (rather than the internal short-circuit failure), most of it is not easy to dissolve the metal lithium to cause ignition and occurrence explosion. 4. Lithium iron phosphate battery: It is an idealized power lithium battery suitable for driving power cars with pneumatic tools. The basic theoretical volume is 170mAh/g, and the detailed data information volume is 160mAh/g. At the safety factor level, the lithium iron phosphate battery has good heat resistance, and the lithium battery electrolyte has a low air oxidation capacity, so the safety factor is high; but the defect is the low conductivity, the production process of the modified material must be improved, and the processed lithium battery electrolysis The liquid volume is too large and the amount used is too much. In addition, because of the large volume and poor reliability of rechargeable batteries, the technology of lithium iron phosphate batteries is still in the scientific research stage at this stage.
