Electrochemical Properties of Silver Powder as the Negative Electrode Material for Lithium Secondary Batteries
Silver powders have been extensively studied as an anode active material for lithium secondary batteries. In the present study, a unique attempt is made to develop silver negative electrode by slurry method, because the silver electrode is a good candidate to replace the commercial graphite electrode for lithium rechargeable batteries. Silver electrode was prepared and its electrochemical properties were characterized gradual increasing test state of charge (GISOC) analysis method. Charge-discharge performance indicates that the initial charge potential range of Li/Ag cells has showed similar behaviors compared with Li/Graphite system and the irreversible capacity fade is also higher than Li/Graphite system.
