TOPLUS^® Tetraethylene Glycol Methyl Ether

RFQ: What is Tetraethylene Glycol Methyl Ether?
Tetraethylene Glycol Methyl Ether is a Colorless and transparent liquid, also known as TEGME.

What are the uses of Tetraethylene Glycol Methyl Ether?

TEGME is widely used in lithium batteries to improve their overall performance.

- TEGME can act as a high-voltage stabilizer, inhibiting the continuous oxidative decomposition of the electrolyte under high voltage, preventing gas generation, impedance increase, and transition metal dissolution, thereby significantly improving the cycle life and coulombic efficiency of high-voltage batteries.

- As a multifunctional additive for lithium-sulfur batteries, TEGME significantly improves the capacity retention and cycle stability of lithium-sulfur batteries, making it one of the key additives for lithium-sulfur battery electrolytes.

- Furthermore, it can also act as a regulator of the physicochemical properties of the electrolyte, balancing the overall performance of the electrolyte system.

What are the benefits of Tetraethylene Glycol Methyl Ether?

- Tetraethylene Glycol Methyl Etherexcellent high-voltage stability, effectively addressing the core challenge of electrolyte decomposition under high voltage.

- TEGME also possesses wide-range application potential; its good low-temperature performance helps improve the overall operating temperature range of the electrolyte.

TOPLUS^® Tetraethylene glycol methyl ether has evolved from a common specialty solvent into a strategic, high-performance electrolyte functional additive. It precisely targets the two core needs of next-generation lithium-ion battery development: higher energy density (achieved by increasing operating voltage) and enhanced safety.
