The electrochemical performance of RLM electrode materials has been studied by galvanostatic cycling, Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). Fig. 2 show the results.The theoretical lithium storage capacity of RLM used in this paper is 605.48 mAh g −1 (only Ga is considered). ...
As lithium metal reacts violently with water and can thus cause ignition, modern lithium-ion batteries use carbon negative electrodes and lithium metal oxide positive electrodes. Rechargeable lithium-ion batteries should not be confused with nonrechargeable lithium primary batteries (containing metallic lithium).
