The lithium dendrites issue presents a major challenge limiting the commercialization of Li metal anodes for high-energy-d. batteries. Herein, an AgPF6-LiNO3 hybrid electrolyte additive was introduced into a carbonate electrolyte, which was found to induce the formation of a homogeneous dense layer of Ag-Li alloy seeds with small sizes on the Li metal surface. The formation mechanism of such fine Ag-Li alloy seeds on the Li metal substrate was evaluated, which revealed an interesting synergistic effect between AgPF6 and LiNO3. The occurrence of such a dense layer of Ag-Li alloy seeds was found to play a significant pos. role in homogeneous nucleation and growth of Li dendrites, and LiNO3 could inhibit the growth of Li and act as a grain refiner during a repetitive plating/stripping process, thus enabling profoundly improved structural stability and excellent long-term cycle performance for the Li anode during the cycling process. With the co-presence of AgPF6-LiNO3 in the electrolyte, the relevant sym. cells could work steadily for 3000 h with slight polarization at a d. of 0.5 mA cm-2; and the Li-graphite battery can exhibit good cycle performances and deliver a specific energy d. of 374 W h kg-1 at a power d. of 747 W kg-1. The experimental process involved the reaction of Vinylene carbonate(cas: 872-36-6Related Products of 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Related Products of 872-36-6
