Abstract

A battery having a cathode and an anode is provided with a three-dimensional porous framework. The anode includes an anode active material lithiated with a lithium source. The lithium particles from the lithium source are alloyed or intercalated with the anode active material during diffusion to form the three-dimensional porous framework. The porous framework provides reduced electrode deterioration due to volume expansion.

Claims (8)

1 . A battery comprising:

a cathode; and

an anode comprising a silicon active material having a first porosity of about 10 to 45 percent lithiated with a printable lithium composition comprised of a lithium metal powder, a polymer binder compatible with the lithium metal powder, a carbon-based rheology modifier compatible with the lithium metal powder, and a non-polar solvent compatible with the lithium metal powder and with the polymer binder; wherein on electrolyte addition the active material is alloyed or intercalated with lithium particles diffused from the printable lithium composition to form an anode having a second porosity increased from the first porosity by about 5% to about 15% when the silicon active material is alloyed or intercalated with lithium particles diffused from the printable lithium composition to form a three-dimensional porous framework within the anode and provides improved rate capability between about 20 to 50% at a 2C charge rate compared to a non-lithiated silicon anode.

2 . The battery of claim 1 , wherein the anode formed by the silicon active material and printable lithium composition has a porosity between about 25% and about 60%.

3 . The battery of claim 1 , wherein the lithium metal powder is stabilized lithium metal powder.

4 . The battery of claim 1 , wherein the carbon-based rheology modifier comprises a carbonaceous material selected from the group consisting of carbon black, carbon nanotubes, graphite, hard carbon, and graphene.

5 . The battery of claim 1 , wherein the polymer binder has a molecular weight of 1,000 to 8,000,000 and is selected from the group consisting of unsaturated elastomers and saturated elastomers.

6 . The battery of claim 1 , wherein the non-polar solvent is selected from the group consisting of acyclic hydrocarbons, and aromatic hydrocarbons.
