The correct way of lithium battery and matters needing attention

Source: 2020 - 03 - 23 15:00 hits: time attention the correct way of lithium battery and lithium ion batteries are often referred to as lithium batteries. In our daily life, the lithium battery is closely related to the use of mobile phones and laptop computers. Now the use of lithium battery has very deep and wide, but people's common sense to lithium battery may also is not very understanding. Lithium battery way of charging and discharging right way is? The matters of attention in the lithium battery application? With these problems, we continue. Lithium batteries are divided into lithium battery and lithium ion batteries. Today's mobile phones and laptops use lithium ion battery, often referred to as lithium batteries. Lithium ion batteries are now being used in mobile phones and the like, and the true lithium ion battery is not used in the daily electronic products, because they are dangerous. Lithium ion battery energy density is high, the output voltage. Small self-discharge, at 10% per month. No memory effect. Working temperature range for - 20℃~ 60℃。 Loop performance is good, fast charge and discharge, the charging power of up to 100%, the output power. Long service life. No environmental pollution, known as the green cells. Correct way of lithium batteries: standard charging methods: with 0. C5 constant-current charging to the battery voltage of 2 and 4. 20 v, to constant voltage charging, charging current zero. 01 c5 is full. Standard charging method is often used to calibrate battery capacity. Fast charging methods: with 1 c5 constant-current charging to the battery terminal voltage is 4. 20 v, instead of constant current charging, and charging current as' 0. 01C5'。 Note: (fast charging method 1) The initial charging current not too big, avoid batteries overheating, leaking, blowout phenomenon. When the battery terminal voltage at 4. 20 v, must immediately regulation to constant pressure, higher requirements on voltage ( Fault '0. 5% ') , must use 4. More than 5 multimeter measurement. Lithium battery discharge way: standard discharge way: 0. 2 c5 constant discharge to the voltage of the battery. 75V。 Because in daily use are difficult to meet this condition, so it makes little sense. This method is mainly used for calibration battery capacity. Quick discharge method: due to the lithium ion battery internal resistance is very small, so allow large current discharge, at room temperature, with 54 minutes (1 c5 discharge current can discharge More than 90%) ; 1. 5 c5 discharge time more than 30 minutes; 2 c5 discharge more than 23 minutes; And allow more current discharge in a short period of time.
