Silicon-carbon composite powders find practical applications primarily in lithium-ion batteries. Let’s explore how they contribute:
Anode Materials:
– Nano silicon particles are integrated in a stable carbon matrix to reduce typical side reactions pristine silicon.
– The highly engineered carbon coating increases cycle-life and helps alleviate volume changes during lithiation and delithiation.
– They enhance the ion-conductivity of silicon-based negative electrode materials.
Energy Storage:
– Silicon-carbon composite contributes to higher energy density and improved battery performance.
– By combining silicon’s ultra-high theoretical capacity with carbon’s stability, they broaden the practical applications of silicon-based anodes.
Versatility Across Industries:
– From smartphones to electric cars, our silicon-carbon composites power it all.
– Renewable energy storage, wearables, and beyond—the possibilities are limitless.
Eco-Friendly Innovation:
– Reduce reliance on fossil fuels with cleaner, greener energy solutions.
– Use of 100% renewable power and sustainable precursor offer a active material with extremely low carbon footprint of 4.58 tCO2/7Si/C
In summary, silicon-carbon composite powders play a crucial role in advancing lithium-ion battery technology.
Our Si/C composite powder is a ready to use as a drop-in replacement in graphite-containing electrodes. It contributes to a sustainable future without compromising performance.
