He says, they use laser welding at 1:40, but it looks like normal spot welding for me.

Macribs,
I did extensive research on copper alloys for battery use. There are some awesome copper alloys out there.... You just can't get them anywhere. I looked for months, sent dozens of emails and scoured the world. Unless you want tons of the stuf your out of luck. :(
