During the initial deposition process of from an additive- free electrolyte solution, the lithium negative electrode maintains a very uniform surface morphology, however once the total deposition amount increases, the lithium electrode starts to form agglomerated particles of the dendritic lithium.
Lithium metal has been considered as the ideal negative electrode material for these battery chemistries, because of its low equilibrium potential ﾂｹ3.04V vs. SHE and high speci・ capacity >3800mAhgﾂｹ1.3
The surface morphology of the electrodeposited lithium is basically dependent upon the kinetics of the deposition process4 and the preferred crystal growth mode.5Especially the electro- chemical reaction at the lithium-electrolyte interphase is the dominant process to determine the surface morphology.
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
No uneven deposit is observed on the electrode even in the magni・‘d image Fig. 2(e). On the other hand, the lithium negative electrode after the electrodeposition process for 10Ccmﾂｹ2had an uneven surface covered with aggregated lithium particles as shown in Fig. 2(c).
