摘要：

We first report the exceptional cycleability of SnO2 anodes by atomic layer deposition (ALD) over directly on stainless steel substrates without any capacity fade for 500 cycles. Perfect choice of cycling potential (5-800 mV vs. Li) and synthesis condition yielded such performance with reversible capacity of 646 mAh g(-1) at current density of 5 mu A cm(-2). Further, SnO2 undergoes the conversion reaction along with alloying reaction enables higher capacity than alloying reaction, however, experiencing severe capacity fade during cycling. Obtained results on SnO2 anodes by ALD technique certainly influence the impact on the development of solidstate, thin film and 3D Li-ion batteries. (C) 2013 Elsevier Ltd. All rights reserved.
