상세 정보

This product is designed for advanced lithium-ion battery research, specifically as a high-capacity anode material with improved rate capability and reduced volumetric expansion. Silicon suboxide (450) offers a balanced combination of electrochemical performance and structural stability, making it suitable for next-generation energy storage applications. To maintain its properties, the material requires vacuum-sealed storage. During electrochemical testing, it is recommended to use a ternary electrolyte such as KLD-1230C, and electrode slices should be dried at 85°C for 4 hours prior to assembly. Available in multiple quantities ranging from 20 g to 1000 g, this material provides researchers with a consistent platform for evaluating high-energy-density anode systems.

The material needs to be stored in vacuum seal

The electrolyte used during the test is: ternary electrolyte (KLD-1230C)

Baking conditions for pole slices: 85℃ bake for 4h

High capacity, high magnification, low expansion
