One of the factors holding back widespread acceptance of electric vehicles has been the development of battery storage. Until now, there has been nothing analogous for batteries to the computing industry’s Moore’s Law, which has seen integrated circuits become significantly more powerful, faster, and cheaper with each generation. While there have been incremental improvements in energy density — the primary drawback to battery power — a number of promising new battery technologies have not panned out.
Now, a research team headed by John Goodenough, whose 1980 invention of a cobalt-oxide cathode made powerful lithium-ion batteries possible, has announced the development of a solid-state battery cell that not only has the potential (no pun intended) to store three times as much power as a conventional lithium-ion cell, but also replaces the cells’ liquid electrolytes with a glass compound. That would eliminate the fire and explosion hazard known to Li-ion power packs. (Read More…)
