Abstract

A method of assembling a battery cell (106) comprising: receiving a jelly-roll (101) comprising an anode layer, a cathode layer and at least one separator layer between the anode and cathode layer, the jelly-roll comprising a substantially cylindrical body (103) having a first end (104), at which one or more cathode layer connectors project that couple to the cathode layer, and a second end (105), opposed the first end; applying at least an insulation tape (305), comprising an electrically insulating tape, around the cylindrical body (302) such that a first part (306) of the insulation tape winds around the cylindrical body to, at least in part, hold the jelly-roll in a rolled state, and a second part (307) of the insulation tape overhangs the first end; and folding the second part of the insulation tape to at least partially cover the first end.
