2. 18650 battery - Wikipedia

   en.wikipedia.org/wiki/18650_battery

   An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.

3. List of battery sizes - Wikipedia

   A lithium primary battery, not interchangeable with zinc types. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses. According to consumer packaging, replaces (BR) 2 ⁄ 3 A. In Switzerland as of 2008, these batteries accounted for 16% of lithium camera battery sales. [75]

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.

5. Battery nomenclature - Wikipedia

   en.wikipedia.org/wiki/Battery_nomenclature

   Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.

7. Lithium nickel manganese cobalt oxides - Wikipedia

   en.wikipedia.org/wiki/Lithium_nickel_manganese...

   Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM) are mixed metal oxides of lithium, nickel, manganese and cobalt with the general formula LiNi x Mn y Co 1-x-y O 2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles , acting as the positively charged cathode .
