Title: Nanoscale silicon as anode for Li-ion batteries: The fundamentals, promises, and challenges

Silicon (Si), associated with its natural abundance, low discharge voltage vs. Li/Li+, and extremely high theoretical discharge capacity (~ 4200 mAh g-1,), has been extensively explored as anode for lithium ion battery. One of the key challenges for using Si as anode is the large volume change upon lithiation and delithiation, which causes a fast capacity fading. Over the last few years, dramatic progress has been made for addressing this issue. In this paper, we summarize the progress towards tailoring of Si as anode for lithium ion battery. The paper is organized such that it covers the fundamentals, the promise offered based on nanoscale designing, and the remaining challenges that need to be attacked to allow using of Si based materials as anode for battery.
