A novel selenium-carbon composite has been fabricated by embedding selenium in metal-organic framework-derived microporous carbon polyhedra. Such interconnected microporous carbon polyhedra possess a large surface area and pore volume to effectively confine Se, and suppress the dissolution of polyselenides in the electrolyte. This selenium-carbon composite shows ultrastable cycling performance when used as a cathode material for lithium-selenium batteries.
