Why is the capacity of the forklift lithium-ion battery insufficient

1. After the electric forklift battery arrives at the user after leaving the factory, it cannot be installed and used in time, resulting in long-term storage. Long-term storage will definitely cause self-discharge and lead to insufficient capacity. It is not correct to store the battery for a long period of time, and it must be recharged at intervals. 2. The positive plate of the forklift battery is corroded and deformed, causing insufficient capacity. The positive plate of the forklift battery is an important factor affecting the working life of the battery. The capacity of the electric forklift battery charge-discharge cycle, especially the capacity drop under the deep cycle, is closely related to the quality deviation of the positive plate. 2.1 The active material on the positive grid softens and falls off. Microscopically, there are macropores and micropores in the active material. The size of the macropore exceeds 0.5cm. It is composed of many small pores. As the discharge cycle progresses, the surface of the active material shrinks, forming a core and forming a coral-like structure. The accumulation of small pores in the second discharge cycle increases, so that large pores are continuously added, which destroys the structure of the positive electrode and causes the active material to fall off. The important reason for these situations is that the forklift battery is charged and discharged with high current. To prevent occurrence, ensure the current of charging and discharging and prevent the phenomenon of overcharging or overdischarging. 2.2 Positive grid corrosion The corrosion rate of the grid depends on the composition of the grid alloy, but the higher the storage temperature, the faster the corrosion rate, the deeper the discharge depth, and the more severe the corrosion. 3. Sulfation of the negative plate of the electric forklift battery: In normal operation, the PbSO4 particles on the negative plate are small, and the discharge can easily be restored to velvet lead, but sometimes the hard-to-reducible lead sulfate is generated inside the battery, called sulfuric acid Salinization. There are many reasons for the salting of the negative electrode, such as the inability to charge in time after discharge, long-term storage of the battery, causing serious self-discharge, excessive electrolyte concentration, long-term insufficient charging, and long-term discharge at high temperature. This lead sulfate is difficult to restore by conventional methods. In this way, the reduction of active materials will inevitably affect the capacity of the forklift battery. 1. Do not charge the battery after the battery is completely exhausted, which will affect the battery life. 2. Do not use the phone for a long time during the charging process. Please wait for the charging to be completed before using the phone. 3. Do not over discharge. When the device prompts that the battery is low, you should charge it; charge it until the device is automatically shut down, and the battery has been over-discharged. This will affect battery life. 4. Do not overcharge. When the charger gives a full charge instruction, the charger should be unplugged. Current chargers generally have a design that stops charging automatically. It does not matter if the battery is not removed from the charger for a short period of time, but if the charger is connected for a long time, the voltage of the power grid rises late at night, and the voltage of the charger that has stopped charging will rise. After high, it will continue to charge, causing the battery to overcharge. This will affect battery life. 5. If the battery is not used for a long time, it should be charged to 60%, stored separately in a cool and dry place (for models with removable batteries), and recharged every 4 or 5 months.
