Voltage of Durable High Energy Density Lithium Iron Phosphate Lifepo4 Cell

From:CTECHI GROUP Limited     Release time:2018-11-29

Overview:Lithium iron phosphate battery: The discharge voltage of the whole battery composed of graphite is about 3.2V. The cathode material with excellent high temperature performance is the best cathode material at present. At present, most of the Chinese lithium power enterprises are making lithium iron phosphate batteries. The preparation process is rigorous, the rate performance is still good, and the compacting density is low. Invention patents in the United States, so the future may be due to patent problems.

Lithium manganate batteries: Manganese is abundant in reserves, lithium manganate is cheap and has good rate performance. Manganese dissolves easily in electrolyte at high temperature, which can be improved by coating treatment. Low capacity, high discharge voltage, higher than the commonly used lithium cobalt 3.7V. The preparation process is mature, not only in the patent issue. Japan and Korea mainly make lithium manganate. The typical representative of China, Mengguli, has made lithium manganate batteries.


The standard voltage of durable Primary cylindrical lithium manganese dioxide cell is 3.7V, the maximum charge voltage is 4.3V and the minimum discharge voltage is 2V.


The standard voltage of durable high energy density lithium iron phosphate lifepo4 cell is 3.2V, the maximum charge voltage is 3.65V and the minimum discharge voltage is 2V.


Battery is a device that converts chemical energy into electrical energy by holding electrolyte solutions and metal electrodes in part of the space of cups, tanks or other containers or composite containers that generate electric current. It can be divided into positive pole and negative pole. With the progress of science and technology, batteries generally refer to small devices that can generate electricity.

Durable High Energy Density Lithium Iron Phosphate Lifepo4 Cell

1. The energy density of lithium manganate batteries is larger than that of lithium iron phosphate batteries. In other words, lithium manganate batteries with the same capacity can be made smaller.


2. The cycle life of lithium manganate batteries is not as good as that of lithium iron phosphate batteries. Generally, the cycle life of lithium iron phosphate batteries is 300-500 times, and the cycle life of lithium iron phosphate batteries can be 1800-2000 times. To put it bluntly, the life of lithium iron phosphate battery with the same capacity specification is 4-5 times longer than that of lithium manganate battery.


3. The safety of lithium manganate battery is not as good as that of lithium iron phosphate battery.


4. The maximum single capacity of lithium manganate battery can only be 10AH, and that of lithium iron phosphate battery can be 300AH at present.


5. The range of temperature and environment of lithium manganate batteries is not as wide as that of lithium iron phosphate batteries.
