  • Publication number: 20210171353
    Abstract: The present disclosure relates to compositions comprising at least two different carbonaceous components, at least one being a surface-modified carbonaceous particulate material typically having a relatively high spring-back, and at least one other component being a carbonaceous particulate material (such as graphite) generally having a lower spring-back and/or a higher BET specific surface area than the surface-modified carbonaceous material component. Such compositions are particularly useful for making negative electrodes for lithium-ion batteries and the like in view of their beneficial electrochemical properties, particularly in automotive and energy storage applications.
