Abstract: A battery includes a battery cell stack disposed within a housing such that a gap exists between the battery cell stack and an inner surface of the housing. The battery cell stack includes a plurality of battery cells that each include a positive electrode tab and a negative electrode tab electrically coupled to an electrode assembly and extending from the electrode assembly outside of a case. The positive electrode tabs and/or the negative electrode tabs of the plurality of battery cells extend into the gap between the battery cell stack and the inner surface of the housing. A filler material fills the gap and provides a thermally conductive pathway between the positive electrode tabs and/or the negative electrode tabs of the plurality of battery cells and the inner surface of the housing. The filler material includes a thermally conductive particulate component distributed throughout a polymeric matrix component.

Abstract: Disclosed herein is a battery module comprising a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature. Disclosed herein too is a method comprising disposing in a battery module a flame retardant layer; where the battery module comprises a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature.

Abstract: System and methods for estimating a temperature of a battery are presented. In some embodiments, a method of estimating a temperature of a battery system may utilize measured battery system temperature data and measured ambient temperature data. Based on the measured temperature data, an average estimated temperature of the battery system may be determined using, at least in part, an extended Kalman filter and an energy balance process model associated with the battery system.
