3.2V lithium battery voltage capacity relationship

Lithium battery voltage 3.2V has nothing to do with capacity.

The voltage of the 3.2 V lithium battery is fixed, determined by electrochemical characteristics and has no direct relationship with capacity.

The unit of lithium battery capacity is “ampere-hour”, which is directly related to current. Capacity = discharge time × discharge current.

1WH=Lithium battery voltage V*Ah capacity (Ah)=Lithium battery voltage V*mAh capacity (mAh)/1000;

According to the definition of the current formula: I=Q/t, it can be seen that Q=It, the unit of current I is mA (milliampere), t represents time, the unit is hour (hour), so Our battery capacity unit is mAh.

That is, if the capacity of a battery is 1000 mAh and the operating current is 100 mA, it can theoretically provide power for 10 hours. ?

However, it appearse the formula that Q=This does not involve voltage, so this unit can only indicate how many coulombs of charge can be accommodated inside the battery. But that can't explain how much work the battery can do or what the maximum power it can provide. The working voltage of different types of products is different. Therefore, you will often see a number in Wh next to mAh. The work the battery can do W=UIt=UQ, the unit of voltage U * current I is W (Watt), so W in the battery is represented by Wh, which indicates the amount of work the battery can do . ?

Distance: The voltage of a 6600 mAh battery is 14.4 V, 14.4*6600=95.04 Wh, so the total work it can release is 6 .6*14.4*3600=342144 joules of work. The general voltage of the mobile phone is 3.7, so the theoretical work that the above 5200 mAh mobile power supply can do is 3.7*5.2*3600=69264 joules of work. ?What is a quantity directly proportional to voltage, current and time. mAh is generally used as an indicator of battery charge and discharge. This is an indicator proportional to the current and charging (discharging) time of the battery. To make it comparable or convertible to Wh, the battery voltage must also be known. In simple terms, Wh=mAh/1000*voltage.
