Eco-Friendly Additives for Secondary Battery Electrolytic Copper Foil : an OS Matrix-based White Space Analysis

Key Points

• This research aims to analyze trends and gaps in electrolytic copper foil additives based on patent data, focusing on sustainability and performance.
• Collected and refined data on electrolytic copper foil patent applications related to secondary batteries since 2000.
• Classified additives based on functional groups: carboxyl, hydroxyl, amino, thiol, and sulfonic.
• Mapped key requirements against solutions using an OS Matrix to identify gaps in technology.
• Amino and sulfonic groups exhibit low technological concentration but high market applicability, indicating potential gaps.
• Suggested eco-friendly and high-performance additive candidates such as taurine, methionine, and lignosulfonic acid.
• Discussed benefits including uniform deposition, grain refinement, corrosion inhibition, and improved process sustainability.
