Product Introduction

1,4-Di-t-butyl-2,5-bis(2-methoxyethoxy)benzene (DBBB, CAS No. 1350770-63-6) is a functional organic redox shuttle molecule developed for lithium-ion battery electrolyte systems and advanced electrochemical energy storage applications.

As a representative redox shuttle additive (ANL-RS2), DBBB undergoes reversible oxidation–reduction reactions during battery operation, allowing controlled electron transfer within the electrolyte. This mechanism helps protect lithium-ion batteries from overcharge conditions, improving battery safety and operational stability.

The molecule contains a substituted aromatic core with tert-butyl groups and methoxyethoxy side chains, providing suitable redox activity, electrolyte compatibility, and molecular stability for high-performance battery research.

Working Principle

Unlike conventional electrolyte salts such as LiPF₆ or LiFSI, DBBB is not a lithium salt and does not provide lithium ions.

It functions as a redox shuttle molecule:

1. During normal battery operation, DBBB remains stable in the electrolyte.
2. Under overcharge conditions, DBBB is oxidized at the cathode.
3. The oxidized species migrates to the anode and is reduced.
4. The reversible redox cycle transfers excess charge and prevents excessive voltage increase.

This process helps reduce risks associated with overcharging, including electrolyte decomposition and thermal instability.
