In article number 1801908, Yu‐Guo Guo, Xiao‐Dong Guo, and co‐workers develop a 3D hollow fusiform LiMn 2 O 4 cathode material with preferentially exposed stable {111} facets and seamless outer structure. The reasonable geometrical structure design suppresses manganese dissolution from the cathode/electrolyte interface and avoids the deposition of Mn 2+ , resulting in excellent performance for lithium‐ion batteries.
