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 → LixSn → Sn → SnO2/SnO2−xcycle during charging/discharging. SnO2−xelectrode has a reversible capacity of 1340 mAh g−1and retains 590 mAh g−1after 100 cycles. The addition of highly conductive, well-dispersed reduced graphene oxide further stabilizes and improves its performance, allowing 950 mAh g−1remaining after 100 cycles at 0.2 A g−1with 700 mAh g−1at 2.0 A g−1. Conductivity-directed microstructure development may offer a new approach to form advanced electrodes. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim |
