[0002] The liquid metal battery is a high-temperature energy storage technology based on molten electrodes and electrolytes. Its concept was first systematically proposed and developed by Professor Donald Sadoway's team at the Massachusetts Institute of Technology (MIT) in the early 21st century. The core feature of this battery is to use naturally stratified liquid metals (such as magnesium, antimony, and lead) as the negative electrode, molten salts (such as chloride and fluoride mixtures) as the electrolyte, and another liquid metal or alloy (such as nickel-tin alloy) as the positive electrode, operating at high temperatures (usually 300-700°C). Since both the electrode and the electrolyte are in a molten state, the packaging technology of the battery becomes a key link to ensure its long-term stable operation, and the welding process directly affects the air tightness, electrical contact performance, and structural reliability of the battery.
