The inner core is essentially the same as the outer core (iron nickel sulfide); with one major difference: a liquid/solid phase relationship. The inner core is hotter than the outer core, but the pressure more than compensates for that, forcing the inner core into a solid. As the temperature of the Earth (very) slowly cools, the boundary between inner and outer will disappear and the core will be entirely solid. This will probably take a few of billion years so don't hold your breath waiting for it to happen.
The mantle is a different story...

Umm... try Wikipedia. I doubt you've searched "everywhere" on the internet and found nothing.
Inner core and outer core are different - see this article:
