The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery’s state of charge (SoC) – how much energy is left in the battery. Here’s a simplified SoC chart for a typical lithium-ion battery:
The ideal voltage for a lithium-ion battery depends on its state of charge and specific chemistry. For a typical lithium-ion cell, the ideal voltage when fully charged is about 4.2V. During use, the ideal operating voltage is usually between 3.6V and 3.7V. What voltage is 50% for a lithium battery?
Rechargeable lithium-ion batteries can be used in embedded systems and have among the best energy density when compared with other battery technologies. This is the topic of this blog post, which provides a broad overview of the application of lithium-ion batteries in embedded systems. This post is the first of a 4-part series.
The same principle as in a Daniell cell, where the reactants are higher in energy than the products, 18 applies to a lithium-ion battery; the low molar Gibbs free energy of lithium in the positive electrode means that lithium is more strongly bonded there and thus lower in energy than in the anode.
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.
In a good lithium-ion battery, the difference in electron electrochemical potential between the electrodes is mostly due to the electric potential difference Δ ϕ resulting from (chemically insignificant amounts of) excess charge on the electrodes that are maintained by the chemical reaction.
