1. A battery, comprising:
a housing at least partially enclosing an electrochemical cell; and
a phase change material portion;
wherein:
the phase change material portion has a melting point, at 1 atm of pressure, of greater than or equal to 30° C. and less than or equal to 80° C. and a latent heat of fusion, at 1 atm of pressure, of greater than or equal to 100,000 J kg−1;
the housing is configured to apply, during at least one period of time during charge and/or discharge of the electrochemical cell, an anisotropic force with a component normal to an electrode active surface of the electrochemical cell defining a pressure of at least 10 kgf/cm2; and
the phase change material portion is located such that during at least some of the at least one period of time during which the housing applies the anisotropic force, some or all of the phase change material portion experiences a pressure defined by the anisotropic force that is zero or at least 50% lower than an average pressure defined by the anisotropic force experienced by the electrode active surface.
