Super-cooled liquid sulfur microdroplets generation and dissolution on Au thin film coated on glass. The electrochemical cell was kept below −40 °C(in dry ice and ethanol mixture bath) while being charged and discharged. Play speed is 2x of the actual speed.

Direct electrochemical generation of supercooled sulfur microdroplets well below their melting temperature
