英文摘要	SnO2-based lithium-ion batteries have low cost and high energy density, but their capacity fades rapidly during lithiation/delithiation due to phase aggregation and cracking. These problems can be mitigated by using highly conducting black SnO2-x, which homogenizes the redox reactions and stabilizes fine, fracture-resistant Sn precipitates in the Li2O matrix. Such fine Sn precipitates and their ample contact with Li2O proliferate the reversible Sn Li Sn-x Sn SnO2/SnO2-x cycle during charging/discharging. SnO2-x electrode has a reversible capacity of 1340 mAh g(-1) and retains 590 mAh g(-1) after 100 cycles. The addition of highly conductive, well-dispersed reduced graphene oxide further stabilizes and improves its performance, allowing 950 mAh g(-1) remaining after 100 cycles at 0.2 A g(-1) with 700 mAh g(-1) at 2.0 A g(-1). Conductivity-directed microstructure development may offer a new approach to form advanced electrodes.; National Key Research and Development Program of China [2016YFB0901600]; National Science Foundation of China [51402334, 51502331]; Science and Technology Commission of Shanghai [14520722000]; Key Research Program of Chinese Academy of Sciences [KGZD-EW-T06]; US Department of Energy (BES) [DE-FG02-11ER46814]; SCI(E); ARTICLE; 24; 29
