Abstract

As one of the major problems facing lithium ion batteries, sluggish charge transfer often induces undesirable large resistance, overpotential, and round trip inefficiency of batteries during recharge. The need to improve charge transport kinetics is motivating research into directions that would rely on high quality heterostructure designs, since it is reported that the synergistic effects and as-formed inbuilt electric fields of heterostructures could facilitate charge transport across the heterostructure, as well as enforce interactions between the active phases. Heteromanipulation holds great promise for realizing efficient interconnects between charge transport kinetics and heterostructure designs. However, most previous studies delineate ensemble measurements of a given static heteroelectrode, which do not permit isolating and dissecting the effects of heterostructural manipulation on electrochemical performances individually. Here, by choosing conversion type electrodes as an example and comparing s...
