A joint research team from Tohoku University and the University of California, Los Angeles (UCLA) has made a significant advance towards high-voltage metal-free lithium-ion batteries by using a small organic molecule: croconic acid. Most reported organic batteries to date, however, possess a relatively low (1-3V) working voltage.

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al. Neither approach is practical.

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. This shift of emphasis leads inevitably to the electrolyte, catalysts, and organic multiple-electron redox centers.

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The high energy storage has stimulated a worldwide study of Li-air batteries. A typical Li-air battery discharges at 2.5-2.7 V vs. Li/Li + at room temperature.

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Lead organization. Description. Ginkgo BioWorks. (UC
