  "textContent": "Batteries having convoluted, freeform shapes. These batteries can have curved and twisted surfaces that are freeform and do not have a constant radius or degree of rotation. A stack of battery layers can undergo a two-step heat press. The first heat press can be applied to the battery layers in a limited, low-stress region. This heat-press step can help to reduce delamination during a second heat-press step. In this second heat-press step, some or all of the battery layers can be pressed into a freeform shape and heat can be applied. The battery layers can then be placed in an enclosure.",
