Material behaviour

Electrochemical behaviour

Store energy through controlled reactions.

What it means

An electrochemical cell pairs reactions at electrodes with a route for ions through an electrolyte and electrons through an external circuit. Elements are often present in compounds whose structures matter enormously. Capacity, lifetime and safety depend on the complete cell and its management, not on one ingredient.

Look for it in everyday life.

Lithium-ion cells move lithium ions between engineered electrodes; their chemistries vary.
