摘要：

Amorphous MoS3, prepared by chemical or thermal decomposition of ammonium thiomolybdate, has been found to react readily with n butyl lithium and sodium and potassium naphthalides to give compositions MxMoS3 (0 ≤ x ≤ 4, M = Li, Na, K). Electrochemically, MoS3 cathodes in lithium cells react with up to 3.8 Li per MoS3 under constant current conditions (0.5 mA/cm2) above 1.40 volts. The mean discharge voltage of Li MoS3 is close to 2.0 volts which together with the high coulombic capacity results in a cell with high theoretical energy density. On recharge at constant current the system shows good reversibility. © 1979.
