An elaborate low-temperature electrolyte design towards high-performance liquid metal battery

Solid electrolyte membrane-containing rechargeable high-temperature molten salt electrolyte-based batteries

“…Using multi-cation molten salt electrolytes and alloy electrodes, as well as lowering the operating temperature, allows for the suppression of metal solubility in molten salt electrolytes and an enhancement in LMB performance. [219][220][221][222][223] Wang K. et al designed a LikLiF-LiCl-LiIkSb-Pb liquid metal battery, showing 98% coulombic efficiency and 73% round-trip energy efficiency with charge-discharge current densities of 275 mA cm −2 at 450 °C, and the charge-discharge curves at different current densities are shown in Fig. 9c.…”

Enhancing cycling stability in NaǁZn liquid metal batteries with Fe- based foam negative current collectors

“…These collectors have a single shape in a circular battery shell. Meanwhile, the negative current collector usually employs materials like graphite [10], stainless steel, or Febased alloy [11][12][13], and transition metals like Mo [14][15][16] and W [17], fashioned into various forms, including rods [14][15][16][17][18], flakes [18], cups [19] and foam [11][12][13][20][21][22][23][24][25][26][27][28][29][30].…”
