Lithium iron phosphate battery

　　It refers to the lithium ion battery, molecular formula: LIFEPO4;

　　Lithium iron phosphate can reach 350 ° C-500 ° C, while lithium manganate and lithium cobaltate are only about 200 ° C.

　　Division -a polymer film with special molding, with a micropore structure,

　　You can pass the lithium ion freely, and the electrons cannot pass;

　　Negative electrode -active substance is graphite, or carbon that is similar to graphite structure;

　　Optocrone -carbonate solvents with lithium hexofluorophosphate,

　　The polymer uses a gel -like electrolyte;

　　Battery shell -divided into steel shells, aluminum shells, aluminum plastic films (soft packaging), etc.

　　The voltage of lithium ion power battery is nickel -cadmium battery, three times the nickel -metal hydride battery, and two times the lead -acid battery. This is an important reason that reflects the lithium -ion power battery higher than energy. At the same time, the number of series used in lithium -ion power batteries will be larger than lead -acid batteries and nickel -hydride batteries. If the number of single batteries in power batteries, the higher the consistency requirements of the single battery in the battery pack, the worse the life span. After the battery pack has problems in the actual use process, it is usually one and two of them. There is a problem with a single battery and then causes the entire set of batteries. Therefore, it is not difficult to understand why 48V lead -acid batteries have higher feedback than 36V lead -acid batteries. From this perspective, lithium battery is more suitable for the use of power batteries. For example, the lithium battery of 36V requires only 10 monomers, while 36V lead -acid batteries need 18 monomer batteries, namely 3 12V battery packs, and six single -format batteries per 12V, six single batteries, composition.

　　Lithium titanate battery:

　　Lithium titanate is used as the negative electrode material of lithium ion batteries, and it can form a 2.4V or 1.9V lithium ion secondary battery with lithium manganate, ternary material or lithium iron phosphate.

　　Lithium titanate can also be used as a positive electrode, which is a 1.5V secondary battery composed of lithium metal or lithium alloy negative electrodes.

　　Due to the high safety, high stability, long life and green environmental protection of lithium titanate, it is expected that lithium titanate materials will definitely become the negative electrode material of the new generation of lithium -ion batteries in a few years and be widely used in new energy vehicles , Electric motorcycles and application areas that require high safety, high stability and long cycle. Lithium titanate battery voltage is 2.4V, with a maximum voltage of 3.0V, and the charging current is greater than 2C.

　　Lithium titanate batteries are also composed of four parts:

　　Positive, negative electrode, diaphragm, electrolyte, battery shell;

　　Lithium titanate characteristics are as follows:

　　Test data shows that under the conditions of 6C charging, 6C discharge, 100%DOD, the cycle life of lithium titanate mono battery exceeds 25,000, and the remaining capacity exceeds 80%. At the same time life.
