Application No. 08/661,532
BACKGROUND
Appellants' invention relates to a method of forming an
electrode material for an anode of a lithium ion battery, a
method for making such a battery, the electrode material, and
the battery. Exemplary claims 1, 13, 18 and 20 are reproduced
below.
1. A method of forming an electrode material for a
lithium ion battery comprising:
(A) pyrolyzing a composition comprising a polysilane to
form a ceramic material; and
(B) introducing lithium ions into the ceramic material to
form an electrode material.
13. In a rechargeable lithium ion battery, the
improvement coprising:
an anode which comprises a material formed by:
(A) pyrolyzing a composition comprising a polysilane to
form a ceramic material; and
(B) introducing lithium ions into the ceramic material to
form an anode.
18. An electrode material for a lithium ion battery
comprising a material of the structure:
