12V150Ah Precautions for using lithium iron phosphate battery pack:
1. Do not use the battery in an extremely hot environment, otherwise the battery will overheat and catch fire, affecting the performance of the battery and shortening the service life of the battery.
2. It is forbidden to charge the battery under fire or extreme heat conditions! If the battery leaks or emits an odor, remove it immediately from an open flame.
3. It is forbidden to short-circuit the battery with wires or other metal objects. It is forbidden to transport or store the battery together with necklaces, hairpins or other metal objects.
4. It is forbidden to pierce the battery case with nails or other sharp objects or hammer or pedal the battery to avoid potential hazards such as internal short circuit and heat.
Improve the ionic conductivity of the electrolyte
Lithium ions play in the positive/negative materials, and the game in the electrolyte is swimming.
In swimming competitions, how to reduce the resistance of water (electrolyte) is the key to speed improvement. In recent years, swimmers have generally wore shark suits, which can greatly reduce the resistance of water formation on the surface of the human body, thereby improving athletes' performance and becoming a very controversial topic.
Lithium ions should travel back and forth between the positive and negative electrodes, just like swimming in the "pool" composed of electrolyte and battery case. The ionic conductivity of the electrolyte is the same as the resistance of water. The speed of swimming for lithium ions is very large. influences. At present, the organic electrolyte used in lithium ion batteries, whether it is a liquid electrolyte or a solid electrolyte, has a low ionic conductivity. The resistance of the electrolyte becomes an important part of the overall battery resistance, and the influence on the high rate performance of the lithium ion battery cannot be ignored.
In addition to increasing the ionic conductivity of the electrolyte, it is also important to focus on the chemical and thermal stability of the electrolyte. When charging and discharging at a large rate, the electrochemical window of the battery varies widely. If the chemical stability of the electrolyte is not good, it is easy to oxidize and decompose on the surface of the positive electrode material, which affects the ionic conductivity of the electrolyte. The thermal stability of the electrolyte has a great influence on the safety and cycle life of the lithium ion battery. Because the electrolyte will generate a lot of gas when it is decomposed by heat, on the one hand, it poses a hidden danger to the safety of the battery, on the other hand, some gases on the surface of the negative electrode. The SEI membrane produces a destructive effect that affects its cycle performance.
Therefore, selecting an electrolyte with high lithium ion conductivity, good chemical stability and thermal stability, and matching with the electrode material is an important direction to improve the rate performance of the lithium ion battery.
