How to increase the capacity of lithium batteries? How to increase the capacity of lithium batteries Lithium battery capacity refers to the storage capacity of the battery. Capacity is the central parameter of lithium batteries. The battery capacity of lithium batteries is insufficient, and the only way to improve is to replace large-capacity batteries. Because the processing capacity of lithium batteries has been fixed in time, and with the increase in use over time, the capacity will be slightly reduced. Ways to increase the capacity of lithium batteries Lithium battery capacity can be selected in parallel with lithium batteries. In other words, by connecting the positive electrode of the lithium battery with other batteries, and the negative electrode with other batteries, the capacity of the lithium battery can be increased without changing the battery output voltage. If the batteries are connected in series, the output voltage of the batteries will increase, and the capacity will not change. With the same number of lithium batteries, the premise to meet these requirements is: 1. If 3.6/3.7v lithium batteries are used, the positive and negative of each battery must be welded in parallel to the original battery to form a serial number, a pair One, there is nothing wrong, because the original internal battery balance protection board is used, this requirement must have electrical knowledge, ability, and understanding of the protection board and anti-static balance. 2. Whether the spatial azimuth angle is satisfied, it is necessary to calculate its own measurement value. 3. Make it clear whether to use a separate 3.6v lithium battery or a 3.2v lithium iron phosphate battery. The two cannot be confused. How to increase the capacity of lithium batteries? Use of the data contributed to the capacity of lithium batteries: The first one here is the most direct way to increase the capacity density of the positive and negative active materials. Important directions include: 1. Use more information: such as positive lithium-rich data, high-voltage ternary data, high-voltage lithium cobalt oxide data, binary data, etc.; negative soft carbon, hard carbon, silicon tin-based compounds. 2. Using positive and negative data, it has a higher compaction density. 3. When using adhesives, conductive active materials are better: this can reduce the guessed content of adhesives and conductive agents in the application, thereby improving the ability of the dressing per unit mass; in addition, reducing adhesives and conductive agents The dosage can also improve production functions such as compaction of active materials. 4. Use smaller thickness rebound data: After the lithium battery is cycled, the thickness will rebound to a certain extent; in planning, the rebound thickness after rebound should be retained; when using data with a smaller thickness rebound, you can The saved space for thickness rebound is transferred to the planned thickness of the unit, and then the planned capacity of the unit can be added. 5. Choose a data system with better matching function: A data combination with poor matching performance will not only reduce the cycling function of the lithium battery, but also affect the multiplier function and even the performance of the positive and negative electrodes; similarly, when the data is well matched, you can Improve functions such as restraint, circulation and expansion rate. How to increase the lithium battery capacity? 1. Use gram to display more data, such as positive electrode lithium-rich data, high-voltage ternary data, high-voltage lithium cobalt oxide data, binary data, etc.; negative soft carbon, hard carbon, silicon-tin-based compounds. 2. Using positive and negative data, it has a higher compaction density. 3. When using adhesives, conductive active materials are better: this can reduce the guessed content of adhesives and conductive agents in the application, thereby improving the ability of the dressing per unit mass; in addition, reducing adhesives and conductive agents The dosage can also improve production functions such as compaction of active materials. 4. Use smaller thickness rebound data: After the lithium battery is cycled, the thickness will rebound to a certain extent; in planning, the rebound thickness after rebound should be retained; when using data with a smaller thickness jump (we Now see that these data are also data with good circulation function), the saved thickness jump can be transferred to the planned thickness of the cell, and then the planned capacity of the cell can be added. Lithium batteries have light weight, large capacity, and good stability, and have important application values u200bu200bin consumer electronics, medical equipment, equipment manufacturing, aerospace and other fields. During the test, the battery functional indicators are the same, but the difference in battery properties is exposed during use.
