Abstract:
The patent describes a battery electrode composition featuring composite particles. Each composite particle includes an active material designed to store and release ions during battery operation, which typically causes a significant volume change in the active material. To counteract this, a porous, electrically-conductive scaffolding matrix is provided, within which the active material is housed. This scaffolding matrix serves to structurally support the active material, ensure electrical connectivity, and accommodate its volume changes.

Independent Claim Overviews:

• Claim 1: This claim describes a battery electrode composition made of composite particles. Each particle contains an "active material" (which expands and contracts significantly when storing and releasing ions) embedded within a "porous, electrically-conductive scaffolding matrix." The matrix is designed to provide structural support, maintain electrical connections, and absorb the volume changes of the active material.
• Claim 11: This claim outlines a method for creating the battery electrode composition. The method involves providing an active material (that undergoes substantial volume changes during ion storage/release) and then forming a porous, electrically-conductive scaffolding matrix around or within which this active material is disposed. The scaffolding matrix, once formed, supports the active material, electrically connects it, and manages its volume changes.
• Claim 15: This claim describes a battery that includes a negative anode, a positive cathode, and an electrolyte. The key feature is that at least one of the anode or cathode components incorporates the composite particles detailed in Claim 1.
