How to deal with battery leakage? Why lithium-iron batteries are not easy to leak? During the production process, the batteries are leaking to different degrees whether they are manually packaged or automatically packaged. For lithium batteries, it is mainly due to the welding process during the manufacturing process and the poor sealing treatment of the welding seam, resulting in no welding or micro-hole on the welding seam, leading to leakage. So how to deal with battery leakage? Why lithium-iron batteries are not easy to leak? The following to give you a popular science.
First, how to deal with battery leaks
Generally speaking, the battery leakage is mainly due to poor sealing between the top cover or bottom slot, this cause is the most common in daily use, there are three other reasons may lead to battery leakage, respectively, the safety valve leakage, leakage at the junction and other parts of the leakage. Regardless of which causes the battery leakage need to be promptly investigated and dealt with in a timely manner.
Battery electrolyte is very corrosive, do not let it touch the skin or clothing, the battery should be immediately thrown away, first wipe the night with hand paper, then dry cloth with alcohol or white wine repeatedly wipe two times, available anhydrous ethanol, etc. will be completely clean electrolyte leakage, otherwise it will continue to corrode the battery joints. Already rusty battery joints should be scraped clean with a knife, sandpaper, and a layer of solder can be soldered with a soldering iron to prevent corrosion if possible.
1. first check the appearance of the battery, check whether the battery shell is broken and cracked, many times the battery leakage is caused by the collision of the battery during the ride and breakage, so the appearance should be checked first.
2. remove the battery panel and check the condition of the safety valve to see if there is any trace of leakage from the safety valve, if the safety valve is leaking, it needs to be overhauled or replaced.
3. In the case of the first two parts are intact, the next is to check the airtightness of the battery, pressurized and inflated in water to see if there are bubbles, if there are bubbles, it means that there is leakage.
4. Observe the battery when charging to see if there is electrolyte outflow to determine the extent of battery leakage.
Second, why lithium-iron batteries are not easy to leak?
The electrolyte inside the alkaline battery is strongly alkaline, which has a corrosive effect on metals and plastics, while lithium-iron batteries have the characteristics of large capacity, small size, light weight, high current discharge and excellent low temperature performance. Compared with alkaline batteries, lithium-iron batteries are not easy to leak because the electrolyte is completely adsorbed on the diaphragm, and there is no liquidity inside the battery, which will not corrode electronic devices.
Lithium-iron batteries are sealed with a semi-sealed structure, and seals are added during the production process; the electrolyte of lithium-iron batteries is an organic solvent containing lithium salts instead of an aqueous solution, so even if it is accidentally leaked, it will not corrode metals, circuit boards, or plastics, while the electrolyte used in alkaline batteries is potassium hydroxide, which is a very strong alkaline substance and will cause serious corrosion to metals and plastics.
The diaphragm and positive and negative electrode materials of lithium-iron batteries are wound in such a way that the electrolyte is infiltrated on the positive and negative electrode materials and adsorbed in the "volume" of the cell formed by the positive and negative electrodes and the diaphragm, so there is no flow of electrolyte in the battery and leakage is avoided at source. In contrast, alkaline batteries use single-layer diaphragm to isolate positive and negative electrodes, and the positive electrode material, negative electrode material and electrolyte are placed separately, so the potassium hydroxide electrolyte inside is in a flowing state and will leak out after a long period of use.
Battery electrolyte leakage is very easy to corrode electronic devices, it is best to discard, lithium battery leakage is indeed rare, but not without leakage; battery leakage and the quality of the battery itself has a great relationship, so users in the purchase process must be recognized as genuine high-quality batteries.
