摘要:
The present invention relates to a novel particulate porous carbon material containing a carbon phase and at least one pore phase, and to the use of such materials in lithium cells, especially lithium-sulfur cells. The carbon phase forms, with the pore phase, essentially unordered co-continuous phase domains, such that the distance between adjacent domains of the pore phase is not more than 50 nm. The invention also relates to a process for producing such carbon materials and to composite materials comprising elemental sulfur and at least one inventive particulate porous carbon material.

Aspects of the invention relate to block copolymers having the properties of thermoplastic elastomers made of blocks on the basis of isobutene monomer units as the soft segment and blocks on the basis of oligoamides composed of at least two base units, each of which comprises an amino or a carbonyl group in the α, β, γ or δ position to each other or directly bound to each other, as the hard segment. Such block copolymers are suited for producing fibers, microfibers, and films.
