1. A curved battery cell comprising:
a positive terminal;
a negative terminal;
one or more curved electrodes comprising at least one curved surface having a non-uniform radius of curvature derived by:
measuring body contours of one or more individuals; and
constructing a model of a body based at least in part on an averaging of the body contours of the one or more individuals, wherein:
the model of the body comprises one or more spline curves; and
the non-uniform radius of curvature of the curved surface substantially matches a non-uniform radius of curvature of the one or more spline curves; and
an outer case encasing the one or more curved electrodes and exposing the positive terminal and the negative terminal.
