Why is voltage important in a lithium ion battery?

In simple terms, voltage is the electrical pressure that pushes electrons through a circuit. For lithium-ion batteries, voltage is crucial because it directly relates to how much energy the battery can store and deliver. Think of voltage like water pressure in a hose. The higher the pressure, the more water (or in our case, energy) can flow.
