LI/FES2 BATTERY AND FABRICATION METHOD THEREOF

摘要

Disclosed are a Li/FeS2 battery and a fabrication method thereof. The Li/FeS2 battery comprises: a housing; a cap; an electrolyte; and a cell. The housing is connected with the cap to form a closed chamber. The electrolyte and the cell are received in the chamber. The cell comprises: a cathode ring; a membrane; a pad; an anode lithium piece; a current-collecting grid; and a steel strip. The anode lithium piece is inserted into the cathode ring. The anode lithium piece and the cathode ring are spaced by the membrane. The current-collecting grid has one end connected to the anode lithium piece and the other end connected, via the steel strip, to the cap. A pad is disposed between the cathode ring and the cap. The fabrication method mainly comprises: fabricating a cathode ring; placing the fabricated cathode ring in the housing, and then adding a membrane, a pad, an anode lithium piece and a current-collecting grid in a sequential order; welding a steel strip to the current-collecting grid; injecting an electrolyte; welding the steel strip to the cap; and sealing the housing. By adopting the structural design of the invention, a capacity of a Li/FeS2 battery increases to 4 Ah, namely above 33.3%.
