Despite the high theoretical capacity of Si anodes, their huge volume change and poor electrical connectivity must be overcome by decreasing the feature sizes of the Si particles to the nanoscale and compositing them with highly conductive carbon materials. To ensure the mechanical integrity of the electrodes with uniform dispersion and good electrical contact of the nano-silicon, the industry has to use a relatively low amount of Si ( 2000 mA h g−1 after 300 cycles) and a commercial-level areal capacity (5.58 mA h cm−2). This strategy offers a new way to design electrodes with a high active material content for high performance batteries.
