However, it is low intrinsic conductivity and volume amplification during service status, prevented it from developing further.
After 360 cycles at 0.1 C, the anode had 2514.8 mAh g −1 capacity and 75.8% capacity retention. Even with a current of 0.2 C, the capacity of 1548.9 mAh g −1 is reached after 1000 cycles. The performance of Si/C can also be improved by a core-shell construction incorporating pores.
Si-based anode materials offer significant advantages, such as high specific capacity, low voltage platform, environmental friendliness, and abundant resources, making them highly promising candidates to replace graphite anodes in the next generation of high specific energy lithium-ion batteries (LIBs).
The anode coating comprises of micrometer Si particles, graphite, and binders and additives. Note that the graphite is electrochemically inactive and only serves as a conductive agent , hence the naming of a silicon-dominant anode.
The anode delivers a capacity of 709 mAh g −1 with a capacity retention of 112% over 500 cycles. Similarly, Guo et al. coated the SiO with a F-doped carbon layer with some voids and pores through annealing. Due to the high electronegativity of F, the F-doped carbon has better conductivity.
Summary for the performance of the Si-based anodes with different binders. Due to the volume expansion of Si material when embedded with lithium, there is a risk of loss of active material on the electrode and destruction of surface SEI film, resulting in continuous electrolyte decomposition. Finally, the active Li + in the battery is consumed.
