Electrochemical Processes and Reactions In Rechargeable Battery Materials Revealed via In Situ Transmission Electron Microscopy

“…or metals (i.e., Sn, Zn, In, Bi, and Cd), [66,67] iii) conversion type electrode materials such as transition metal oxides, metal sulfides, phosphides and nitrides. [68][69][70] Generally, the mechanisms of direct charge storage of three electrode materials are entirely different, resulting in distinct reversible capacity, and structural stability of electrode materials. In addition, with the application of high energy density and high safety energy storage devices, Li metal anodes, solid electrolytes and the interfaces between cathode/anode with solid electrolytes have attracted extensive attention (Figure 5B).…”

Constructing Ni–Co PBA derived 3D/1D/2D NiO/NiCo2O4/NiMn-LDH hierarchical heterostructures for ultrahigh rate capability in hybrid supercapacitors

“…[1][2][3] The development of a high-efficiency, sustainable, and promising energy storage and conversion system has become a research hotspot in recent years. [4][5][6] The hybrid supercapacitor (HSC) with a battery-type positive electrode and traditional capacitor-type negative electrode has emerged as a noteworthy and promising member of a large family of various green energy technologies by virtue of its exceptional specic power and fast charging-discharging capability. 7,8 Nevertheless, the specic power of HSCs is mainly determined by the morphologies, electrochemical activity and cycling stability of the electrode materials.…”

Room-Temperature Rapid Self-Healing Polymer Binders for Si Anodes in Highly Cycling-Stable and Capacity-Maintained Lithium-Ion Batteries

“…However, at present, anode materials with a relatively low theoretical specific capacity (372 mAh g –1 ) badly restrict the development of high specific capacity batteries. Consequently, much attention has been paid to seek high-capacity anode materials for lithium-ion batteries (LIBs). − Due to its high theoretical specific capacity (4200 mAh g –1 ), a relatively low operating voltage (around 0.4 V vs Li + /Li), as well as advantages of environmental friendliness and rich abundance, Si has become one of the most promising anode materials. − Unfortunately, great volume change (around 300%) of Si particles occurs during the embedding and de-embedding process of Li + , which results in squeezing and pulverization of Si particles, destroying the electrode structure and thus leading to an unstable solid electrolyte interphase (SEI). In brief, the volumetric expansion/shrinking of the Si anode largely reduces the cycling life of the electrode, which indeed hurdles the practical application of the Si anode. ,− …”
