Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
In particular, the classification and new progress of HESDs based on the charge storage mechanism of electrode materials are re-combed. The newly identified extrinsic pseudocapacitive behavior in battery type materials, and its growing importance in the application of HESDs are specifically clarified.
In particular, we provide a deep look into the matching principles between the positive and negative electrode, in terms of the scope of the voltage window, the kinetics balance between different type electrode materials, as well as the charge storage mechanism for the full-cell.
Therefore, the cathode is the positive electrode during cell discharge (i.e., when the cell/system provides energy) and the negative electrode during cell charge (i.e., when energy needs to be supplied to the cell/system) . It also means that chemical energy is converted into electric energy and vice-versa , .
Long periods at high state of charges (SOCs) increase the reduction rate at the negative electrode (NE) and the oxidation rate at the positive electrode (PE) that lead to the formation of the SEI and PE-SEI, respectively. [ 12]
As the energy storage device combined different charge storage mechanisms, HESD has both characteristics of battery-type and capacitance-type electrode, it is therefore critically important to realize a perfect matching between the positive and negative electrodes.
