Lithium-Ion Battery

Lithium ions are a vital part of the electrochemistry of a lithium-ion (Li-ion) battery, a cutting-edge battery technology.

• Lithium atoms in the anode are ionised and separated from their electrons during a discharge cycle.
• When the lithium ions proceed from the anode to the cathode, passing through the electrolyte along the way, they rejoin their electrons and become electrically neutral.
• As they are so tiny, the lithium ions can pass through a micro-permeable barrier that separates the anode from the cathode.
• In part because of lithium’s small size (third only to hydrogen and helium), Li-ion batteries are capable of ....
