Three methods for repairing lithium-ion mobile phone batteries:
1. Gently wipe the metal contacts on the lithium-ion battery and the phone with a clean eraser or other cleaning tool to help with charging and battery life.
2. Wrap the old mobile phone's lithium-ion battery pack, which has been stuck to the phone's automatic shutdown mechanism, tightly with three layers of cling film, ensuring a vacuum seal. Then, wrap the cling film with three layers of newspaper to completely seal the lithium-ion battery. Place it in the freezer for 48 hours. After 48 hours, remove the battery and carefully remove all six layers of paper wrapping. The lithium-ion battery should not have expanded or deformed due to freezing. Allow it to cool for a while before charging.
3. Completely discharge a near-dead lithium-ion battery, then recharge it to reactivate it. The specific method involves deep discharging the phone, which depletes its internal energy to achieve a deeper recharge. This requires unconventional methods. A special device connects the phone to a low-voltage light bulb; the battery's charge is transferred to the bulb until it is completely discharged. Normally, if the phone's voltage drops below its rated 3.6 volts after being connected, it will automatically shut down. After being fully discharged, the recharged battery can be used for a longer period.
Methods for repairing lithium-ion batteries in electric vehicles:
1. Repackaging: After an entire lithium-ion battery pack is damaged, we often perform charge-discharge tests on the electric vehicle's lithium-ion batteries. During the inspection, we often find that 50% of the batteries in a group are not damaged. This is because, in a series-connected lithium-ion battery pack, the lagging performance of individual batteries leads to a decrease in the overall battery pack's function, resulting in a decline in the overall battery pack's performance.
2. Water Replenishment: Replenishing water on a lithium-ion battery in an electric vehicle after approximately four months of use can extend its lifespan by an average of three months or more. It should be noted that each water replenishment process involves overcharging the battery, transitioning it from a near-starved state to a starved state. This overcharging is beneficial for increasing battery capacity.
3. Desulfation: Battery repair equipment is used to desulfate the batteries.
4. Microparticle generator: A microparticle generator is connected in parallel to the battery to repair it. This method is good for repairing lithium-ion batteries in electric vehicles. However, because the repair is quite thorough, it often completely eliminates the possibility of battery sulfation for electric vehicle lithium-ion batteries that are not over-discharged and are intended for continued use.
5. Comprehensive Repair Methods for Lithium-ion Battery Packs in Electric Vehicles: Regularly inspect electric vehicle lithium-ion batteries, promptly desulfurize and replenish water, charge individual batteries, and reassemble the battery pack. Battery manuals state that if the battery is maintenance-free, generally do not add water. If water must be added, first check the electrolyte density of the electric vehicle battery itself, and add water of appropriate concentration or no concentration as needed. This will increase the capacity of the lithium-ion battery pack or extend its service life.
In conclusion, the repair of lithium-ion batteries for electric vehicles is entirely feasible. Shineng's lithium-ion battery voltage balancing repair device is currently one of the only devices in the industry capable of perfectly repairing lithium-ion batteries. It is the best equipment for enabling the secondary use of lithium-ion batteries and restoring over 90% of their power performance and range.
