▎ 摘 要
NOVELTY - Composite material preparation involves using graphene aerogel and electrode system. The metal ion is added with an electrolyte. The mixture is heated at 25-90 degrees C for 24 hours. The obtained mixture is introduced with inert gas. The obtained mixture is heated at 100-900 degrees C for 1-10 hours. USE - Method for preparing composite material (claimed). ADVANTAGE - The method enables to prepare composite material in a cost-effective and eco-friendly manner.
