Schematic of a lithium ion battery. Initially, lithium cobalt oxide was used as the cathode and polyacetylene as the anode. Later in 1985, it was found that using lithium cobalt oxide as the cathode and graphite as the anode produced an excellent secondary battery with enhanced stability, employing the frontier electron theory of Kenichi Fukui.

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.
Lithium is especially useful, because its ions can be arranged to move between the anode and the cathode, using an intercalated lithium compound as the cathode material but without using lithium metal as the anode material. Pure lithium will instantly react with water, or even moisture in the air; the lithium in lithium-ion batteries is a less ...
The lithium in a lithium-ion ("Li-ion" for short) battery makes up the cathode and anode, aka the positive and negative sides of a battery cell. The lithium ions move around inside the positive ...
Schematic of lithium–air battery charge and discharge cycles. In general lithium ions move between the anode and the cathode across the electrolyte. Under discharge, electrons follow the external circuit to do electric work and the lithium ions migrate to the cathode. During charge the lithium metal plates onto the anode, freeing O
Lithium ions intercalate between the layers upon discharging, remaining between the lattice planes until the battery gets charged, at which point the lithium de-intercalates and moves to the anode. [4] Points in a solid solution phase diagram between the end members LiCoO 2, LiMnO 2, and LiNiO 2 represent stoichiometric NMC cathodes. [5]
A solid-state silicon battery or silicon-anode all-solid-state battery is a type of rechargeable lithium-ion battery consisting of a solid electrolyte, solid cathode, and silicon-based solid anode. [1] [2] In solid-state silicon batteries, lithium ions travel through a solid electrolyte from a positive cathode to a negative silicon anode. While ...
Anode-free lithium ion batteries have been demonstrated using a variety of cathode materials, such as LiFePO 4, LiCoO 2, and LiNi 1/3 Mn 1/3 Co 1/3 (NMC 111).. These intercalation-type cathodes typically offer limited Li content (14.3 at.% for LiFePO4, 25 at.% for LiCoO2 and LiNixCoyMn1-x-yO2), although they remain the primary research targets. [2]
