International Classification:

H01M 10/6571
H01M 10/615
H01M 10/635
H01M 10/052

Abstract:

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 T or T; and a switch that activates R when the temperature of the battery is outside of either T or 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.
