Introduction to the types of lithium-ion batteries

1. Lithium cobalt oxide battery: The major feature of the whole configuration process is that when the battery is fully charged, there are still many lithium-ion batteries with positive levels. In other words, there is not a large number of lithium ion batteries on the negative stage adhering to the positive stage. However, in the case of overcharging, unnecessary lithium ion batteries on the positive stage will still sneak into the negative stage. If it is allowed, metallic lithium will appear 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 lithium-ion battery electrolyte is carbon acid grease, which has low lightning and melting points, it will ignite or even explode at high temperatures. It is relatively simple to manipulate the composition of lithium dendrites in small-volume lithium-ion 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-ion batteries. 2. Polymer lithium ion battery: Compared with kinetic energy, the basic theory that can be used in practical activities has a very large development. It is related to lithium cobalt oxide battery, which can better give full play to its high-capacity effect, but at this stage Polymer lithium ion batteries also use lithium cobalt oxide batteries and organic chemical lithium ion battery electrolytes, so the safety factor problem has not been dealt with at all. In application, assuming a short-circuit fault occurs, the rechargeable battery will cause an excessive amount of current. The lithium-ion battery electrolyte of the polymer material lithium-ion 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 more caused by a polymer material lithium-ion battery. Big risk. 3. Lithium manganate battery: The data information of lithium manganate battery has certain advantages. It can ensure that the positive lithium ion battery can be completely inserted into the negative carbon hole under the condition of full charge. Like lithium cobalt oxide batteries, there will be a certain amount of content, which prevents the formation of dendrites from the source. This is all theoretical understanding. In fact, it is assumed that the purpose of applying lithium manganate batteries is to better enable the rechargeable batteries to take on a large external force. Perhaps the shoddy charge is good in the whole process, or it may be that the rechargeable battery is in the whole process of the battery charging cycle system. In an instant, the rapid fitness exercise of lithium-ion batteries appeared. Dendrites appear when the negative stage does not immediately completely digest and absorb the lithium-ion battery. Carry out the test at the original factory of the rechargeable battery to ensure the effectiveness of the result. In general, lithium-ion manganese batteries that meet the system testing standards are generally not prone to safety production 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 an explosion occurred.
