PURPOSE:To increase capacity and allow to take out a battery with a magnet when it is accidentally swallowed by using austenite family atainless steel for a positive can and a clad plate having ferrite family stainless steel for a negative cap. CONSTITUTION:Austenite family stainless steel is used for a positive can 1 and a two layer clad plate comprising mother material 6b of ferrite family stainless steel and laminating material 6a of copper or a three layer clad plate comprising copper-ferrite family stainless steel-nickel obtained by using nickel 6b on the other side are used for a negative cap 6. For example, a 0.20mm. thick SUS304 plate are used for the positive can 1 and a 0.30mm. thick Ni-SUS430-Cu three layer clad plate are used for the negative cap to assemble an LR1120 battery shown in the figure. |
