Cyclic triolborate electrolyte salts for double-layer capacitors

Overview

This solution offers a class of cyclic triolborate compounds developed as potential electrolyte salts for double-layer capacitors (also known as electrochemical double-layer capacitors or supercapacitors). The core innovation lies in the ability to tune the solubility of these salts by systematically varying functional groups and heteroatoms within the molecular structure. This tunability addresses one of the key challenges in supercapacitor electrolyte design, where solubility directly influences ionic conductivity, voltage window, and overall device performance. The technology is relevant to manufacturers of energy storage devices, battery and capacitor developers, and companies seeking improved electrolyte materials for high-power applications.

Technical specifications

Key features:

• Cyclic triolborate molecular framework functioning as electrolyte salt candidates
• Solubility can be modulated through variation of functional groups attached to the core structure
• Solubility can further be adjusted through incorporation of different heteroatoms
• Designed specifically for use in double-layer capacitor electrolyte formulations
• Boron-based chemistry offering potential advantages over conventional electrolyte salts

How it works:

The compounds are synthesized as cyclic triolborate structures, where boron is incorporated into a cyclic framework bearing three hydroxyl-derived oxygen atoms. By modifying the functional groups and heteroatoms present in the molecule, researchers can control how the salt dissolves in various solvent systems. This allows matching of electrolyte properties to specific capacitor designs and operating conditions, potentially improving metrics such as equivalent series resistance, energy density, and cycle life.

Technology readiness level

The compounds are at an early research stage. Synthesis has been carried out as part of the research hypothesis validation, and the focus has been on establishing the relationship between molecular structure and solubility behavior. Further validation, including electrochemical performance testing in actual double-layer capacitor configurations, is needed to confirm practical utility and benchmark performance against established electrolyte systems. The technology is currently best suited for collaborative research partnerships aimed at advancing the materials toward application-ready status.
