The lithium compound positive material is the storage library of lithium ions. In order to obtain a lithium -ion battery with a high output voltage, the material for the positive electrode of the battery should be available:
(1) The electrode potential of the relative lithium is high, the composition of the positive electrode material does not change the potential, the ionic conductivity and electronic conductivity rate are high, which is conducive to reducing the internal resistance of the battery;
(2) Lithium ions are embedded in one dehydration, with small changes in the volume of the reaction, and the lithium ion diffusion speed is fast to obtain good circulation characteristics and sky current characteristics;
(3) In contact with the mechanical electrolyte and adhesive, good thermal stability, which is conducive to extending the life of the battery and improving safety performance;
(4) Rich resources, low prices, stable, non -toxic in the air. At present, lithium-ion battery positive materials mainly include layered LICOO2, Linio2, spinel-shaped Limn2O4, olive-shaped LIFEPO4, and triangular composite material LIMNXNIYCO1-X-YO2.
The positive pole material is the key to the development of lithium ion batteries. The currently widely used lithium -ion battery positive material is lithium drill acid (LICOO2), but because the CO in lithium drill acid is small in nature, the price is relatively expensive, it has a certain toxicity, and during the charging process, the acid drill acid is acidic acid. Due to the deserted part of the metal lithium, it becomes COO2, CO4+is extremely oxidized, which can easily cause safety accidents such as combustion and explosion. Therefore, for the high -power and large capacity, the power batteries that need to be connected in parallel in multiple monomers are required, and there is a huge hidden safety hazard in the use of lithium drill acid. Linio2 has been posted by hope and has not made great breakthroughs so far. Although it has high capacity, there are major difficulties in preparation, it is difficult to synthesize pure phases, and there are certain safety problems. Although Limn2O4 is cheap and good safety performance, its theoretical capacity is not high, and the cycle life, thermal stability and high temperature performance are poor. Therefore, these materials are still difficult to replace lithium drill acid so far. In 1997, A.K.Padhi and others reported for the first time that lithium iron phosphate (LIFEPO4) could be reversed and dehydrated with lithium ions, which can act as lithium -ion battery positive poles, which has attracted widespread attention. Lithium iron phosphate has a wide range of sources, cheap prices, non-toxic, environmentally friendly, and high theoretical than the theoretical compared to (about 170mAh.g-1). Compared with other lithium-ion batteries, it has a relatively moderate working voltage (3.4V, relative to Li+/ Li), not only takes into account the advantages of LICOO2, LINIO2 and Limn2O4 materials, but also the heat and stability, excellent safety performance, and outstanding circulation performance. The preferred material of battery positive materials.
