Here's a concise summary of US patent 11374215:

US Patent 11374215

• Title: Scaffolding matrix with internal nanoparticles
• Assignee: Sila Nanotechnologies Inc.
• Inventors: Gleb Yushin, Bogdan Zdyrko, Addison Shelton, Eugene Berdichevsky, Igor Luzinov, Alexander Jacobs, Eerik Hantsoo, George Gomes.
• Filing Date: February 9, 2022.
• Issue Date: June 28, 2022.
• Abstract: A battery electrode composition is provided that includes composite particles. Each composite particle contains an active material and a scaffolding matrix. The active material stores and releases ions during battery operation, which causes a significant change in its volume. The scaffolding matrix is porous and electrically conductive, housing the active material. It is designed to structurally support the active material, ensure electrical connectivity, and accommodate these volume changes.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Composition Claim): This claim describes a battery electrode composition made of composite particles. Each particle consists of silicon (the active material) that stores and releases ions, leading to substantial volume changes. This silicon is embedded within a porous, electrically-conductive scaffolding matrix. The key feature is that these composite particles can handle active material volume changes during battery operation that are more than 100% greater than any corresponding volume change in the scaffolding matrix. The scaffolding matrix provides structural support, electrical connection, and accommodates these volume changes.

• Independent Claim 11 (Method Claim): This claim outlines a method for manufacturing the battery electrode composition described in Claim 1. It involves providing silicon as the active material, which experiences significant volume changes during ion storage and release. The method then details forming a porous, electrically-conductive scaffolding matrix around this silicon. Similar to the composition claim, the method specifies that the resulting composite particles are capable of accommodating active material volume changes that are over 100% greater than the scaffolding matrix's own volume changes, with the matrix supporting the active material and maintaining electrical connections.

CAFC 2026 Dockets:
As of April 26, 2026, a search for US patent 11374215 within CAFC 2026 dockets did not yield specific results indicating active litigation. The available search tools do not provide direct access to searchable CAFC dockets by patent number for a specific year, making it challenging to definitively confirm or deny the existence of such dockets through automated searching.
