SINOLI LITHIUM ION BATTERY TRAINING IV:


Q81: LITHIUM ION BATTERY Storage:


If the battery is stored for a long time at high temperature, its electrode activity will decay and its service life will be shortened.


Q82: Can the battery be stored in the appliances after use or after long-term use?


If the device is not used for a long time, it is better to remove the battery and put it in a low temperature and dry place. Otherwise, if the device is turned off, the system will still have a low current output, which will shorten the battery life.


Q83: What are the better conditions for battery storage? Do batteries need to be fully charged for long-term storage?


According to IEC standard, should be in battery temperature is 20 ℃ + / - 5 ℃, humidity is stored (20) 65 + %. In general, the higher the storage temperature, your battery capacity of residual rate is lower, on the other hand, too, the refrigerator temperature at 0 ℃ to 10 ℃ when the storage battery the best place, especially for a battery. The secondary battery, even if it loses capacity after storage, can be restored only by recharging and discharging several times.


In theory, batteries always lose energy when they are stored. The battery's inherent electrochemical structure determines the inevitable loss of battery capacity, mainly due to self-discharge. Usually, the self-discharging size is related to the solubility of the anode material in electrolyte and its instability (easy to self-decompose) after heating. The self-discharge of rechargeable batteries is much higher than that of primary batteries.


If you want to keep the battery for a long time, try to keep it in a dry and cold environment and leave the battery at about 40% power. Of course, it's best to take the battery out once a month to keep it in good condition and to keep it from being damaged by a complete battery drain.


Q84: What is a standard battery?


An internationally defined battery as a standard for potential (potential) measurement. It was invented by e. weston, an American electrical engineer, in 1892.


The anode of the standard cell is the mercurous sulfate electrode, the cathode is the cadmium amalgam metal (containing 10% or 12.5% of cadmium), the electrolyte is the acidic saturated cadmium sulfate water solution, actually is the saturated cadmium sulfate and mercury sulfate water solution.
