Enhanced long-term cyclability in Li-Rich layered oxides by electrochemically constructing a LixTM3-xO4-type spinel shell

The poor long-term cycling stability, including the fast capacity fade and the severe voltage decay, has become the main concern hindering the practical application of Li-rich layered oxides, a promising cathode for high-energy-density Li-ion battery. Herein, we design and electrochemically construc...

Zusammenfassung:The poor long-term cycling stability, including the fast capacity fade and the severe voltage decay, has become the main concern hindering the practical application of Li-rich layered oxides, a promising cathode for high-energy-density Li-ion battery. Herein, we design and electrochemically construct a ~10 nm-thick LixTM3-xO4-type (TM = Ni, Co, Mn, 0
