A lithium-ion flow battery is a flow battery that uses a form of lightweight lithium as its charge carrier. [1] The flow battery stores energy separately from its system for discharging. The amount of energy it can store is determined by tank size; its power density is determined by the size of the reaction chamber.
In the diagram above, lithium sinks are described in concentrations (ppm) and displayed as boxes. [1] Fluxes are shown as arrows and are in units of moles per year. [2] Continental rocks containing lithium are dissolved, transferring lithium to rivers or secondary minerals. [2] Dissolved lithium in run-off travels to the ocean. [2]

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.
A schematic illustration of a typical semi-solid flow battery design [1] A semi-solid flow battery is a type of flow battery using solid battery active materials or involving solid species in the energy carrying fluid. A research team in MIT proposed this concept using lithium-ion battery materials. [2]
ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)
The COLEX separation method makes use of this by passing a counter-flow of lithium-mercury amalgam flowing down and aqueous lithium hydroxide flowing up through a cascade of stages. The fraction of lithium-6 is preferentially drained by the mercury, but the lithium-7 flows mostly with the hydroxide.
