Patent ID: 8507135

Claim:
An electrode for rechargeable lithium batteries, the electrode comprising: (a) an intermediate nanocomposite that includes an open porous material, wherein the open porous material includes (i) a homogeneously distributed nanoparticulate electronically active material; (ii) a nanoparticulate electronically conductive binder material; and (iii) sacrificial nanoparticles, wherein an average particle size of the nanoparticles of the electronically active material and an average particle size of the nanoparticulate electronically conductive binder material do not differ more than +100%/−50% or wherein both average particle sizes are in the range of 5 to 500 nm, or wherein the average particle size of the nanoparticles of the electronically active material and the average particle size of the nanoparticulate electronically conductive binder material do not differ more than +100%/−50% and both average particle sizes are in a range of 5 to 500 nm, and wherein the sacrificial nanoparticles have a size in a range of 200 to 500 nm.
