2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   When stored after charging, lithium battery cells degrade more while fully charged than if they are only 40–50% charged. As with all battery types, degradation also occurs faster at higher temperatures. Degradation in lithium-ion batteries is caused by an increased internal battery resistance often due to the cell oxidation.

3. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Other battery chemistries, such as lithium-ion battery technology, cannot be safely trickle charged. In that case, supervisory circuits (sometimes called battery management systems) adjust electrical conditions during charging to match the requirements of the battery chemistry. For Li-ion batteries generally, and for some variants especially ...

4. Float voltage - Wikipedia

   en.wikipedia.org/wiki/Float_voltage

   Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

   The new work on those batteries, ‘An inorganic-rich but LiF-free interphase for fast charging and long cycle life lithium metal batteries’, was published recently in the journal Nature ...

6. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   For example, some battery types can be safely recharged from a constant voltage source. Other types need to be charged with a regulated current source that tapers as the battery reaches fully charged voltage. Charging a battery incorrectly can damage a battery; in extreme cases, batteries can overheat, catch fire, or explosively vent their ...

7. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   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.
