A rechargeable battery whose ohmic resistance is modulated according to temperature is disclosed.

Ohmically modulated battery

A rechargeable battery, module or a pack, having different levels of internal resistance that operate at different temperatures are disclosed. In a subfreezing environment, the battery can exhibit high resistance which once operated or activated, generates heat internally to warm up the battery quickly. Once the batter reaches normal operating temperatures, the battery can switch to a low resistance operating mode, thereby delivering superior power and energy despite operating in a very low ambient temperature.

All climate battery and manufacturing and using the same

Electrochemical cells that include resistor switch assemblies that can operate according to temperature and batteries and power systems including such cells are disclosed.
