Electrolytes in battery technology

Electrolytes are substances that exist as ions. They are second-order conductors, as their ability to conduct electrical current is created when a molecular bond is broken to form ions. These ions form the mobile charge carriers.

Electrolytes are a central component of batteries. They fulfill the important task of ensuring the flow of ions between the electrodes.

Types of electrolytes

Liquid electrolytes: These usually consist of a lithium-containing conductive salt dissolved in a non-aqueous solvent (e.g. carbonic acid esters such as ethylene carbonate or propylene carbonate) and additives. The lithium salt LiPF6 is most commonly used, as it enables good ion movement and offers high chemical stability.

Solid electrolytes: These are rarely used due to their low conductivity. They are difficult to introduce into the cell.

Electrolytes in lithium-ion batteries

Lithium-ion batteries consist of one or more cells, each of which contains an anode, a cathode, an electrolyte and a separator foil. During operation, lithium ions flow from the anode to the cathode through the electrolyte during the discharge process, generating electrical energy. The electrolyte plays the key role in transporting the lithium ions between the cathode and anode.
