On the Description of Electrode Materials in Lithium Ion Batteries Based on the Quantification of Work Functions

Year: 2024

Type: article

Abstract: During charging of a lithium ion battery, electrons are transferred from the cathode material to the outer circuit and lithium ions are transferred into the electrolyte. Here, the energy required to take electrons and lithium ions out of two prototypical cathode materials, LixFePO4 and LixMn2O4 is investigated as a function of the state of lithiation, x. Both electronic and ionic work functions vary significantly with x for LixFePO4 but rather little for LixMn2O4. The relevance of these work functions for the thermodynamic description of lithium ion batteries is discussed.
