A precursor composition of a negative electrode of a Li-ion battery, a negative electrode comprising or formed from the precursor composition, a Li-ion battery comprising the negative electrode, a device comprising the negative electrode, methods of making the precursor composition, negative electrode and Li-ion battery, and uses of the precursor composition or components thereof for increasing discharge capacity and/or reducing discharge capacity loss and/or improving cycling stability of a Li-ion battery comprising the negative electrode.

Compositions and their uses

The present disclosure relates to novel carbon black materials characterized by a good retention of their structure in the compressed state, as shown, e.g., by a relatively high ratio of compressed OAN/OAN. The materials may inter alia be characterized by a low viscosity in dispersions and by exhibiting low electrical resistivity. Such materials can be advantageously used in various applications, for example in the manufacture of electrochemical cells such as lithium ion batteries or as conductive additive in polymer composite materials. The disclosure also describes a procedure for making such a material as well as well as downstream uses and products comprising said carbon black material.
