Package and shipping
The basic principles of a lithium-ion battery are as follows –
When the battery is fully charged the negative electrode is full of lithium ions.
As soon as it is connected to an appliance these lithium ions begin to move through the electrolyte to the positive electrode and this chemical reaction creates the electrical charge at the terminals.
When there are no more lithium ions left on the negative plate the battery is flat and recharging is needed to reverse the process.
How a lithium-ion battery works
but in reality the process is not quite perfect. From the very first discharge and recharge cycle the capacity of the battery degrades.
