Iron-carbon battery electrode reaction

The setup of IRFBs is based on the same general setup as other redox-flow battery types. It consists of two tanks, which in the uncharged state store electrolytes of dissolved ions. The electrolyte is pumped into the battery cell which consists of two separated half-cells. The electrochemical reaction takes place at the electrodes within each half-cell. These can be carbon-based porous , paper or cloth. Porous felts are often utilized as the surface area of the electr. [pdf]

Finished product picture of battery negative electrode material

Lithium ions diffuse in 2 dimensional planes between layers of graphene. Note that after lithium insertion, the distance between graphene layers is larger than that of graphite, which gives approximately 10% volume expansion. Graphite is still the most widely used anode material since its first application to commercial. . Lithium titanate is an anode material with a spinel type structure where the lithium ions occupy tetrahedral sites and move by hopping via intermediate octahedral sites.
