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.
The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries, including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). The design has this name because the cross section of the battery looks like a Swiss roll.
Lithium-ion battery Curve of price and capacity of lithium-ion batteries over time; the price of these batteries declined by 97% in three decades. Lithium is the alkali metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio.

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.
The cathode is lithium nickel cobalt manganese oxide. The use of a solid-state electrolyte reduces the contact of the μSi with the electrolyte to a flat, solid surface. This makes the spreading of Li–Si more reversible. The use of a non-metallic lithium source eliminates the high temperature that metallic lithium batteries require to charge. [1]
Lithium–silicon batteries are lithium-ion batteries that employ a silicon-based anode, and lithium ions as the charge carriers. [1] Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon. [ 2 ]
Rechargeable lithium metal batteries are secondary lithium metal batteries.They have metallic lithium as a negative electrode.The high specific capacity of lithium metal (3,860 mAh g −1), very low redox potential (−3.040 V versus standard hydrogen electrode) and low density (0.59 g cm −3) make it the ideal negative material for high energy density battery technologies.
