A study on LiFePO4/graphite cells with built-in Li4Ti5O12 reference electrodes
In this work, based on the superior electrochemical stability of Li4Ti5O12 (LTO) electrodes, LiFePO4 (LFP)/graphite cells with built-in LTO electrodes as reference electrodes were designed and fabricated. The characteristics of the LTO reference electrodes in the fabricated lithium-ion cells were me...

| description | In this work, based on the superior electrochemical stability of Li4Ti5O12 (LTO) electrodes, LiFePO4 (LFP)/graphite cells with built-in LTO electrodes as reference electrodes were designed and fabricated. The characteristics of the LTO reference electrodes in the fabricated lithium-ion cells were measured and discussed. The experimental data demonstrated that the LTO built-in reference electrodes were simple to prepare and were feasible options for long-term in situ monitoring of the development of potentials and other electrochemical parameters, such as the Li+ diffusion coefficient (DLi) and electrochemical impedance spectroscopy (EIS) information, for both anodes and cathodes. Moreover, it is believed that the adoption of LTO as a reference electrode could be of great significance for long-term monitoring of the charge and discharge behavior of individual electrodes in other kinds of lithium-ion cells. |
