Yes. I see this Talga patent as being the same as the 4680 anode.

An earlier patent by Group 14 used pyrolized polymer to build a carbon scaffold. The patent specification does not have any illustrative diagrams showin the carbon scaffold.

The silicon containing precursor used by Group 14 is silane, disilane, trisilane, tetrasilan, whereas Talga uses industrial grade silicon.

WO2018165610A1DECOMPOSITION OF SILICON-CONTAINING PRECURSORS ON POROUS SCAFFOLD MATERIALS

A method for producing a composite material comprising a porous carbon scaffold and silicon, comprising the following steps:

a. mixing polymer precursors materials and storing the resulting mixture for a period of time at sufficient temperature to allow for polymerization of the precursors;

b. carbonizing the resulting polymer material to create a porous carbon material;

c. subjecting the porous carbon material to elevated temperature in the presence of a silicon-containing precursor and a hydrocarbon material that decomposes at a higher temperature than the silicon containing precursor;

d. elevating the temperature to decompose the silicon containing precursor, resulting in a silicon impregnated carbon materials; and

e. further elevating the temperature to decompose the hydrocarbon material, resulting in a carbon-coated, silicon impregnated carbon material.

Another mob who claim to have 4680 anode formula are StoreDot:
