Probing the degradation of LiCoO 2 in batteries subjected to high-voltage cycling with 17 O solid-state NMR spectroscopy

The long-term cycling stability of LiCoO under high-voltage operation in lithium-ion batteries is still not satisfactory and the mechanism of capacity decay is not well understood. Here we mainly apply O MAS NMR spectroscopy to probe the phase transformation of cycled LiCoO cathodes in both liquid c...
