An application of thin film of silicon on copper foil to the negative electrode in lithium-ion batteries is an option. 10 – 12 However, the weight and volume ratios of copper to silicon become larger, and consequently a high-capacity merit of silicon electrode is spoiled.
In order to examine whether or not a silicon electrode is intrinsically suitable for the high-capacity negative electrode in lithium-ion batteries, 9 – 13 a thin film of silicon formed on copper foil is examined in a lithium cell. Figure 1 shows the charge and discharge curves of a 1000 nm thick silicon electrode examined in a lithium cell.
Carbon materials can effectively enhance the electrochemical performance of silicon electrodes and mitigate the volume changes of silicon anodes during charging and discharging. In this work, we prepared silicon-carbon composites using phenolic resin as the precursor for carbon.
Therefore, a silicon-negative electrode can be made if all of silicon particles are contacted to electronic conductor connected to a current feeder and if the size of silicon particles is below a critical value for the crack formation, resulting in the isolation of each particle leading to capacity failure.
At the same time, the low conductivity of silicon can result in significant electrochemical polarization when charging at high rates. These factors have seriously hindered the commercialization of silicon electrodes.
