摘要： An electrically active electrode material for use with a lithium ion cell, a lithium ion cell, and a method for forming the electrochemically active material electrode material are described. The electrode material is in the form of a sheet or mat formed of a valve metal material formed of filaments of a valve metal not larger than about 10 microns in cross section, and coated with an electrochemically active material such as silicon nanoparticles.
