Abstract

Co-Free Electrodes In article number 2300509, Jyh-Ming Ting, Jeng-Kuei Chang, and co-workers prepare, a Co-free cubic high entropy spinel oxide and cubic+tetragonal high entropy spinel oxide (HESO (C+T)) using solvothermal and hydrothermal methods, respectively. The secondary tetragonal spinel phase in HESO (C+T) introduces phase boundaries and extra defects/oxygen vacancies, enhancing the redox kinetics and electroactivity during lithiation/delithiation. HESO (C+T)||LiNi0.8Co0.1Mn0.1O2 cell shows an attractive gravimetric energy density of ∼610 Wh kg−1.
