“…There are several reports about such safety problems, and many groups have focused on investigating the chemistry of the electrode surface in various ways. [1][2][3][4][5] Thus, the importance of exploring and establishing a proper model of the surface chemistry of battery systems is required for the development of improved LIBs.…”

Lithium-ion batteries with vinylene carbonate (VC) in the electrolyte exhibit superior electrochemical and thermal behavior at elevated temperature, especially with a high Ni content in the cathode material. When VC is added to the electrolyte, polymeric species are formed on the cathode surface by a ring-opening reaction of ethylene carbonate (EC) in the electrolyte and VC, respectively. Through X-ray photoelectron spectroscopy (XPS) depth profiling, we have confirmed that these polymer layers are porous and complementary to each other. XPS results of C1s and O1s show that the outer surface and the inner layer consist of different components. Based on the XPS depth profiling results, we have suggested a reaction mechanism for the formation of a thermally stable layer on the cathode when vinylene carbonate is added to the electrolyte.

“…In the past few decades, silver (Ag) has been frequently utilised in decorating of different electrode materials of LIBs to improve the electrochemical performance because of its high electrical conductivity, high specific capacity and low discharge-charge voltage [13][14][15][16]. In fact, Ag is a promising anode material since it is anti-corrosion and stable in various environments and can be easily obtained by a simple method [17][18][19][20].…”

Dendritic silver hierarchical structures were prepared via a simple electrochemical deposition method in the presence of citric acid. The influence of the molar ratio of citric acid and AgNO 3 , the deposition time and the deposition current on the crystalline and morphology of the products were studied by X-ray diffraction and scanning electron microscopy. Dendritic silver hierarchical structures consist of a long trunk with secondary branches, which grew in a parallel direction with a definite angle to the trunk. The average diameter of the trunk is 230-320 nm, that of the secondary branches is about 250 nm and the length of the branches is about 850 nm. The charge specific capacity of dendritic silver hierarchical structures was stable at around 250 mAh g −1 after 500 cycles at 0.1C. They also exhibited excellent rate capability at the various current rates from 0.1 to 5C.
