Bacterial Cellulose-Based Aqueous Zinc Battery Anode Structure Technology

This technology relates to a zinc/carbon structure combining zinc metal with a carbon current collector derived from bacterial cellulose to improve anode performance in aqueous zinc secondary batteries.

Conventional aqueous zinc anodes have suffered from interfacial instability and by-product formation in aqueous electrolytes, which reduce reaction efficiency and lifespan. This technology applies a bacterial-cellulose-based carbon current collector to stabilize current distribution and ion adsorption/reduction behavior while providing an environment for uniform zinc growth.

As a result, it can reduce concentration resistance and side reactions while improving anode efficiency and long-term stability, thereby contributing to enhanced performance of aqueous zinc batteries.

Key Features:

• It forms a porous conductive framework by applying a carbon current collector derived from bacterial cellulose.
• It stabilizes anode reactions by forming a zinc-containing metal on the carbon structure.
• It is advantageous for suppressing interfacial side reactions and by-product generation in aqueous electrolytes.
