The charging principle of lithium battery

Carbon materials as anode, lithium compounds as the anode lithium ion batteries no metal lithium, in the process of charging and discharging, exist, as long as lithium ion, this is the lithium ion battery. When charging the battery, the battery has lithium ions generated in the anode, generate movement of lithium ions through the electrolyte to the anode. As a cathode carbon layer structure, it has many pores, arrived in the cathode of lithium ion is embedded into the microporous carbon layer, the embedded lithium ion, the more the higher the charge capacity.

Same, when to discharge the battery (i.e., let's process of battery), embedded in the cathode carbon layer of emergence, lithium ions and movement back to the anode. Back to the anode of lithium ion, the more the higher the discharge capacity. We usually say the battery capacity is referring to the discharge capacity.

Without memory effect is prominent advantages of lithium ion batteries, are not possessed by other secondary battery, lithium ion batteries before regardless of is in power has been finished. The lithium battery the biggest characteristic is higher than the energy.

General lithium-ion battery charging current sets between 0.2 C and 1 C, the greater the current, the faster the charging, battery with fever. And large current charging, capacity is not full, because the battery internal demand for electrochemical reaction time. Same as beer, too fast will happen bubble, instead.
