  title = {A Convenient and Versatile Method To Control the Electrode Microstructure toward High-Energy Lithium-Ion Batteries},
  abstract = {<p>Control over porous electrode microstructure is critical for the continued improvement of electrochemical performance of lithium ion batteries. This paper describes a convenient and economical method for controlling electrode porosity, thereby enhancing material loading and stabilizing the cycling performance. Sacrificial NaCl is added to a Si-based electrode, which demonstrates an areal capacity of ∼4 mAh/cm<sup>2</sup> at a C/10 rate (0.51 mA/cm<sup>2</sup>) and an areal capacity of 3 mAh/cm<sup>2</sup> at a C/3 rate (1.7 mA/cm<sup>2</sup>), one of the highest material loadings reported for a Si-based anode at such a high cycling rate. X-ray microtomography confirmed the improved porous architecture of the SiO electrode with NaCl. The method developed here is expected to be compatible with the state-of-the-art lithium ion battery industrial fabrication processes and therefore holds great promise as a practical technique for boosting the electrochemical performance of lithium ion batteries without changing material systems.</p>},
