Method for making a battery can for p-type prismatic cells

A method for making a battery can, comprising:

• identifying battery can dimensions and features, including a battery can length;
• providing an extrusion die with a channel opening and features that correspond with the identified battery can dimensions and features;
• extruding a metal material through the extrusion die to form a battery can extrusion;
• cutting the battery can extrusion into at least one battery can extrusion portion having the identified battery can length;
• stamping at least one stamped metal portion, using a stamping process;
• joining the at least one stamped metal portion to the at least one battery can extrusion portion, using a laser welding process;
• and
• inspecting the battery can to verify joining between the at least one stamped metal portion and the at least one battery can extrusion portion.

A method for making a battery can, comprising:

• manufacturing at least one first battery can portion and at least one second battery can portion, using a first manufacturing process;
• joining the at least one first battery can portion and the at least one second battery can portion, using a second manufacturing process, different from the first manufacturing process;
• and
• inspecting the battery can to verify the joining between the at least one first portion and the at least one second portion.
