Anode and battery using the same

摘要

An anode comprises anode current collector, anode active material layer and protective layer. The anode active material layer is on anode current collect. The anode active material layer is alloyed with anode current collector in portion(s) of interface with anode current collector. The anode active material layer includes tin. The protective layer is disposed on anode active material layer on side opposite to anode current collector. An anode comprises anode current collector (11), anode active material layer (12) and protective layer (13). The anode active material layer is on the anode current collect. The anode active material layer is alloyed with anode current collector in portion(s) of the interface with anode current collector. The anode active material layer includes tin. The protective layer is disposed on the anode active material layer on a side opposite to the anode current collector. The protective layer includes element of simple substance with higher melting point than tin. An independent claim is included for a battery comprising cathode, above mentioned anode and electrolyte.
