A SULFUR-BASED TRANSITION METAL COMPOSITE AND THE NEGATIVE ELECTRODE COMPRISING THE SAME AND THE BATTERY COMPRISING THE SAME

摘要

The present invention provides a type of cost-effective sulfur-based transition metal composite as the negative electrode active material for lithium ion batteries with high capacity. Moreover, a non-aqueous secondary battery using this negative electrode with long cycle life and high capacity is provided. The battery contains a positive electrode, negative electrode, separator, and non-aqueous electrolytes. The negative electrode contains at least one kind of sulfur-based transition metal composites provided in the present invention.
