The electrochemical behavior of lithium-ion battery electrode materials is often studied in the so-called ‘lithium half-cell configuration’, in which the electrode is tested in an electrochemical cell with a lithium metal electrode acting as both counter and reference electrode.
LFP. Consequently, the amount of lithium inserted in FePO 4 in the second full-cell discharge is y=126155 =081. the capacity is limited by the amount of lithium that was inserted in graphite in the previous charge. The capacity lithium in graphite. The half-cell data of graphite shows that the irreversible specific capacity (that is, the dif ference
Thus, the characterization of lithium-ion battery electrodes in lithium half-cells is very useful to study the intrinsic electrochemical properties of the materials, but it does not directly predict the behavior of full-cells, composed of a lithium-ion battery cathode and a lithium-ion battery anode, which are used commercially
Conventionally, new electrodes or other battery advancements are initially studied in the Li-ion half-cell configuration, where the electrode under study is paired against a Li-metal counter electrode and tested with a large excess of electrolyte.
However, the performance of lithium-ion batteries is affected by the electrochemical behavior of the two electrodes composing the battery.
Full-cells are constructed by balancing the capacity of the cathode and anode to make them similar. Specifically, commercial lithium-ion cells are made with anodes that have somewhat higher capacity (around 10%) than the cathodes, with the purpose of preventing lithium plating on the graphite anode .
