batteries
Introduction. Various resources state that the optimal method of charging a li-ion cell -- such as one found in a mobile phone -- is to charge at a constant current (usually <1C) until a certain voltage threshold is reached, then switch to charging at a constant voltage until the charging current drops to about 0.1C, at which point the battery is fully charged.
Fundamentals and perspectives of lithium-ion batteries
Over the past few decades, the world''s industries and population have grown quickly, which has unexpectedly boosted the demand for energy.
