White Paper on Flexible Electrochemical Electrode Technology

Time:2026-06-08Number:1027

Advanced Institute (Shenzhen) Technology Co., Ltd. | Leading Innovation in Flexible Electronic Core Materials

�� Released in June 2026, Technical Version v2.0
1、 Definition and core positioning

Flexible electrochemical electrodes are a type of electrode material and device that can stably perform electrochemical functions (charge transfer, electrochemical reactions, molecular detection, etc.) under deformation conditions such as bending, folding, stretching, and twisting. It breaks through the defect of traditional rigid electrodes being "hard, brittle, and vulnerable", and is the core upstream material of the flexible electronics industry.

Our company's independently developed flexible electrochemical electrodeComposed of a flexible substrate and a conductive functional layer in synergy:

compose function
Flexible substrates (polyimide PI, polyester PET, elastomers, etc.) Ensure mechanical flexibility
Conductive functional layer (carbon nanotubes, graphene, PEDOT: PSS, metal nanowires, etc.) Provide charge transfer capability

Core demand: deformation does not fail, conductivity does not compromise.
