OverviewHistoryDesignFormatsUsesPerformanceLifespanSafety

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also note…

17.2: The Gibbs Free Energy and Cell Voltage

The Relationship between Cell Potential & Gibbs Energy. Electrochemical cells convert chemical energy to electrical energy and vice versa. The total amount of energy produced by an electrochemical cell, and thus the amount of energy available to do electrical work, depends on both the cell potential and the total number of electrons that are transferred …

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.
