1 Introduction. 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).

Here, we demonstrate a method to improve the Li metal cycling at high current densities by using a soft polymer coating on the electrode. The polymer used here is highly viscoelastic, which provides a pinhole-free coating on the Li surface during repeated charging and discharging.
In lithium ion batteries, lithium ions move from the negative electrode to the positive electrode during discharge, and this is reversed during the charging process. Cathode materials commonly used are lithium intercalation compounds, such as LiCoO 2, LiMn 2 O 4 and LiFePO 4 ; anode materials commonly used are graphite, tin-based oxides and transition

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.
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
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.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
Metallic lithium is considered to be the ultimate negative electrode for a battery with high energy density due to its high theoretical capacity.
When only a small amount of lithium (0.1 mAh/cm2) is deposited, the lithium nuclei on the control electrode are relatively dispersed, forming large particles. On the other hand, lithium nucleation on the electrode modi fied with the polymer is relatively uniform and evenly distributed (Figure S6).
