The reason that steel shell of lithium battery is lighter than aluminum shell is that aluminum shell can be made thinner. In terms of lithium battery working mechanism, during charge, lithium ions de-embed and anode volume bulges; when discharge, lithium ions embed into anode and cathode bulges. Suitable aluminum formula can reduce bulge factor.
