Abstract
retained after 400 cycles). An "active center's charge transfer-capacity compensation" model was proposed based on capacity analysis, XPS depth analysis and HRTEM observation to uncover the fundamental reason of the excellent cycle performance. This in situ 2D-2D heterostructure constructing strategy may open up the possibility for designing high-performance LIBs.
