PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment of single crystal ternary cathode material is more stable physical and chemical properties, can be used as one of the higher voltage material system, and more crystal products have certain advantages in safety performance and cycle performance. At high voltage, with the increase of the number of cycles, the internal resistance of the ternary anode material will become larger, and the battery capacity will decay quickly, and the cycle performance will become worse.
At the same time, the continuous expansion and contraction of the particles of conventional polycrystalline ternary cathode materials will lead to the cracking and crushing of the whole secondary sphere, which makes the electrochemical environment of the battery change dramatically, and thus leads to the shortening of the cycle life. Due to the weak connection between the primary particles of small single crystal, the secondary particles are easily broken and the battery performance deteriorates in the cold pressing process of the electrode. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can solve the above situation.
Single-crystal ternary cathode materials are usually irregular massive particles directly composed of one or several large particles (2-5 μm). There is no grain boundary inside the materials, and the microscopic surface is smooth. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment has better structural stability and high temperature resistance, and its material after compaction and high temperature cycle, not easy to break, so as to obtain more excellent high temperature cycle stability.
