Ma, Jin-ling published the artcilePrevention of dendrite growth and volume expansion to give high-performance aprotic bimetallic Li-Na alloy-O2 batteries, HPLC of Formula: 143-24-8, the main research area is lithium sodium alloy oxygen battery dendrite growth volume expansion.
Rechargeable aprotic alkali metal (Li or Na)-O2 batteries are the subject of great interest because of their high theor. specific energy. However, the growth of dendrites and cracks at the Li or Na anode, as well as their corrosive oxidation lead to poor cycling stability and safety issues. Understanding the mechanism and improving Li/Na-ion plating and stripping electrochem. are therefore essential to realizing their technol. potential. Here, we report how the use of a Li-Na alloy anode and an electrolyte additive realizes an aprotic bimetal Li-Na alloy-O2 battery with improved cycling stability. Electrochem. investigations show that stripping and plating of Li and Na and the robust and flexible passivation film formed in situ (by 1,3-dioxolane additive reacting with the Li-Na alloy) suppress dendrite and buffer alloy anode volume expansion and thus prevent cracking, avoiding electrolyte consumption and ensuring high electron transport efficiency and continued electrochem. reactions.
