How It Works


Like an ice cube cools a drink, AllCell's patented phase change material (PCM) surrounds each Li-ion cell to absorb and conduct heat away from the battery.  This maintains a constant temperature throughout the battery pack, which effectively doubles the pack's life and prevents catastrophic thermal runaway (i.e. a fire or explosion). 

AllCell's PCM uses paraffin wax microencapsulated in a custom designed graphite matrix to provide superior cooling.  As the battery discharges, the graphite matrix conducts the heat evenly throughout the pack while the PCM absorbs the heat as it melts to control the temperature.  During resting or charging, the PCM re-solidifies and becomes ready for re-use.
