Provided is an all solid-state lithium battery including solid battery materials and whose ohmic resistance is modulated according to temperature. The all solid-state lithium battery can include a solid electrolyte; at least two terminals for operating the battery at one level of internal resistance (R) over a temperature range of the battery between a first temperature (T) and a second temperature (T); at least one high resistance terminal for operating the battery at a second level of internal resistance (R) outside of either Tor T; and a switch that activates Rwhen the temperature of the battery is outside of either Tor T. The battery can be configured to include at least one resistor sheet embedded within a cell of the battery and electrically connected to the at least one high resistance terminal.

All solid state lithium battery

Rechargeable batteries, charging methods and systems for fast charging of the battery under all environmental temperatures and without causing battery degradation are disclosed. A charging control system for charging a rechargeable battery can include an ohmically modulated battery, a temperature sensor configured to monitor a temperature of the battery: a switch that can electrically engage the battery to a source of electrical current through either a low-resistance terminal or a high-resistance terminal of the battery: and a controller electrically connected to the temperature sensor and the switch and that can receive input from the temperature sensor and is programmed to determine whether to electrically engage the battery to the source of electrical current through either the low-resistance terminal or the high-resistance terminal through the switch based on input from the temperature sensor.
