There are some kinds of battery that only work at those temperatures - molten salt batteries. Used on earth for a few types of missile and some grid batteries.
The special chips described are silicon carbide; note the caveat of much lower transistor density!
Remember that the Russians managed to get photos of the surface with 1970s technology. One of the main obstacles seems to have been getting the lens caps off the cameras once they'd survived the landing.
