RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

What is different is that the electrode material that stores the Li is all-carbon for both the anode as well as the cathode. Therefore the electrodes in our Li-ion full-cell configuration are exclusively made from carbon (PGN) materials into which Li ions are reversibly plated and stored. —Mukherjee et al. Batteries'

Creating the Commodore 64: The Engineers’ Story

Cars That Think

This article was first published as "Design case history: the Commodore 64." Since Commodore had just moved its engineering staff from California to Pennsylvania, communication between the design engineers and the production facilities was not very good, Ziembicki explained. "It It appeared in the March 1985 issue of IEEE Spectrum.
