Abstract

A lithium ion battery electrode formed by the pyrolysis of a siloxane polymer of the structure EQU (R.sup.1 R.sup.2 R.sup.3 SiO.sub.0.5).sub.w (R.sup.4 R.sup.5 SiO).sub.x (R.sup.6 SiO.sub.1.5).sub.y (SiO.sub.4/2).sub.z followed by introducing lithium ions. In this structure, each R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently selected from the group consisting of hydrogen and a hydrocarbon, w is in the range of 0 to about 0.8, x is in the range of 0 to about 0.9, y is in the range of 0 to about 0.9, z is in the range of 0 to 1 and w+x+y+z=1.
