The invention provides an air-sealed dismountable lithium slurry battery module, comprising a housing and lithium slurry battery cells, wherein the housing comprises a top cover of the housing and a lower shell of the housing, and the top cover of the housing is detachably connected with the lower shell of the housing and forms the inner cavity of the housing; each lithium slurry battery cell housing comprises a top cover of the cell housing and a lower shell of the cell housing, the top cover of the cell housing is detachably connected with the lower shell of the cell housing, and the inner cavity of each corresponding lithium slurry battery cell is formed between the top cover of the cell housing and an electrolyte level in the lithium slurry battery cell housing; and the air pressure ofthe inner cavity of the housing is more than or equal to the air pressure of the inner cavity of the lithium slurry battery cell. Thus, the lithium slurry battery module and the lithium slurry battery cells can be easily dismounted, so regular replacement of an electrolyte and exhausting of lithium slurry batteries can be easily carried out. Moreover, better sealing is realized in virtue of pressure difference between the inner cavity of the housing of the lithium slurry battery module and the inner cavities of the lithium slurry battery cells.
