Insights into the conversion behavior of SiO-C hybrid with pre-treated graphite as anodes for Li-ion batteries

Harmonic analysis based method for linearity assessment and noise quantification in electrochemical impedance spectroscopy measurements: Theoretical formulation and experimental validation for Tafelian systems

“…This feature makes the technique suitable for a large range of applications. This explains why it has been widely used in electrochemical related fields as fuel cells [6][7][8][9][10][11][12], batteries [13][14][15][16][17][18], corrosion [19][20][21][22][23], coatings [24][25][26], electrochemical sensors [27][28] and supercapacitors [29][30][31][32]. This electrochemical technique has also been used in fields that are not traditionally related to electrochemistry as biochemical assays [33][34][35][36], oncology [37][38][39] and immunology [40][41], amongst others.…”

Two-step ball-milling synthesis of a Si/SiOx/C composite electrode for lithium ion batteries with excellent long-term cycling stability

“…10 In recent years, there have been many reports on the fabrication of SiO/C composites as anode materials in LIBs by a simple high-energy ball-milling (HEBM) process. [11][12][13][14][15] For instance, Chil-Hoon Doh's group 14 prepared a SiO/C anode through a simple one-step high-energy ball milling process, which showed a reversible charge capacity value of 688 mA h g À1 at the 30th cycle with 99% coulombic efficiency. Later, W. Y. Yoon's group 15 used a W coating to improve the conductivity of one-step ball-milled SiO-graphite composite, exhibiting better charge and discharge behavior under higher current.…”

In Situ Wrapping SiO with Carbon Nanotubes as Anode Material for High‐Performance Li–Ion Batteries

“…However, commercial graphite anodes can't meet the energy demand with a theoretical capacity of 372 mAh g −1 . Therefore, SiO‐based materials are regarded as the promising alternatives to commercial graphite for the next‐generation anode materials because of their ultrahigh theoretical capacity (2400 mAh g −1 ) and relatively low working potential (∼0.5 V) . However, their practical applications are severely hampered by several factors: (1) the huge volume expansion (∼200%) over repeated lithiation/delithiation processes inevitably induces the pulverization of electrode, leading to the formation of new solid electrolyte interphase (SEI) layer on SiO and hence resulting in a rapid capacity fading; (2) the low initial Coulombic efficient (ICE) of SiO causes a huge irreversible capacity; (3) the low intrinsic electronic conductivity of SiO causes poor rate performance …”
