Correct charging current for lithium-ion batteries
This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery''s capacity over time.
Polymer-based battery
To charge a polymer-based battery, a current is applied to oxidize the positive electrode and reduce the negative electrode. The electrolyte salt compensates the charges formed. ... This process, and therefore the rate performance, is limited by the electrolyte ion travel and the electron-transfer rate constant, k 0, of the reaction.
