When the electrodes are connected to a circuit, electrons flow from one electrode to the other, creating an ...
Basic Principles of Battery The electrochemical series Different metals (and their compounds) have different affinities for electrons. When two dissimilar metals (or their compounds) are put in contact through an electrolyte, there is a tendency for electrons to pass from one material to another. The metal with the smaller affinity for electrons loses electrons to the material with the …

Generally, the charging current of lithium batteries is set between 0.2C and 1C. The higher the current, the faster the charging, and the greater the battery heat. Moreover, if the current is too large for charging, the capacity is not total because the electrochemical reaction inside the battery takes time. Like pouring beer, if you run it too ...
