Title: Sandra Hansen and a Cyclically Stable Silicon Anode for Secondary Batteries.

Introduction

Sandra Hansen is an inventor associated with Osterrönfeld, Germany. Her patent work concerns silicon anodes for secondary batteries, with a focus on accommodating the material’s volume expansion during ion intercalation.

Latest Patents

The supplied information lists one patent for Hansen: “Method for Producing a Cyclically Stable Silicon Anode for Secondary Batteries, and Silicon Anode for Secondary Batteries.” The invention uses mesoporous silicon to create space for expansion, particularly during the intercalation of lithium ions. Rather than coating a metal film with silicon, the method deposits metal onto an etched, monocrystalline silicon wafer. The wafer’s two flat sides must be oriented perpendicular to the crystal’s (100) direction.

Career Highlights

The provided career information associates Hansen with Christian-Albrechts University of Kiel. Her listed patent reflects research into electrode materials and design for secondary batteries. The supplied record reports 1 patent.

Collaborations

Hansen’s listed coworkers include Juergen Carstensen and Rainer Adelung. Their names appear alongside the university affiliations provided in the source information.

Conclusion

Sandra Hansen’s listed invention applies mesoporous silicon and a carefully oriented monocrystalline wafer to address volume expansion in secondary-battery anodes.
