Atomically thin materials are a promising alternative to silicon as the basis for new transistors, but connecting those “2D” materials to other conventional electronic components has proved difficult. Researchers at MIT and elsewhere have found a new way of making those electrical connections, which could help to unleash the potential 2D materials and further the miniaturization of components.

April 15, 2021 LITHIUM-ion batteries have made possible the lightweight electronic devices whose portability we now take for granted, as well as the rapid expansion of electric vehicle production. But researchers around the world are continuing to push limits to achieve ever-greater energy densities—the amount of energy that can be stored in a given mass of material—in order to improve the performance of existing devices and potentially enable new applications such as long-range drones and robots. One promising approach is the use of metal electrodes in place of the conventional graphite,...

This research, which he began in 1994 as a graduate student at MIT, was situated at “the interface between the known and unknown,” says Li PhD ’00, the Battelle Energy Alliance Professor of Nuclear Science and Engineering (NSE) and professor of Materials Science and Engineering. “There was a...
