Abstract
The title system with a positive electrode based on a LiNi0.8Co0.15Al0.05O2 mixed layered oxide and a negative electrode of filamentary germanium nanostructures can operate at low temperatures (to −55 °C) in an electrolyte based on propylene carbonate. The energy density of such a battery is about 400 Wh kg−1 (in terms of active compounds), which exceeds that of commercial LiCoO2/C batteries by a factor of 1.25.
