Nano Graf patent
This improvement in capacity retention and coulombic efficiency exhibited by the Test Group cells of the present application is believed to be attributed to the incorporation of pyrolyzed boric acid cross-linked PVA coated silicon and wrapped within graphene. More specifically, it is believed that the pyrolyzed boric acid cross-linked PVA that coats the silicon, provides a buffer medium that surrounds the silicon that helps prevent mechanical degradation of the silicon and stabilizes solid electrolyte interphase (SEI) loss. Furthermore, the graphene wrapping further provides space between the encapsulated silicon and the outer graphene wrapping thereby creating the buffer matrix structure. The buffer matrix structure comprising the polymeric coated silicon and the graphene wrapping thus provides mechanical support of the silicon and provides additional void space within which the coated silicon may expand. In addition, should the coated silicon fracture, the graphene wrapping contains the broken silicon pieces in a congruent configuration reducing capacity loss from electrical disconnection.
