2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

3. Equivalent circuit model for Li-ion cells - Wikipedia

   en.wikipedia.org/wiki/Equivalent_circuit_model...

   The equivalent circuit model (ECM) is a common lumped-element model for Lithium-ion battery cells. [ 1 ] [ 2 ] [ 3 ] The ECM simulates the terminal voltage dynamics of a Li-ion cell through an equivalent electrical network composed passive elements, such as resistors and capacitors , and a voltage generator .

4. 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.

6. Separator (electricity) - Wikipedia

   en.wikipedia.org/wiki/Separator_(electricity)

   Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.

7. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   Lithium-ion polymer batteries (LiPo) are light in weight, offer slightly higher energy density than Li-ion at slightly higher cost, and can be made in any shape. They are available [15] but have not displaced Li-ion in the market. [16] A primary use is for LiPo batteries is in powering remote-controlled cars, boats and airplanes.

9. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.
