Lithium malonatoborate additives enabled stable cycling of 5 V lithium metal and lithium ion batteries

Improving Stability of LiCoO2 Cathode by Using Lithium Bis(Trifluoroborane)‐5‐Cyano‐2‐(Trifluoromethyl) Benzimidazolide as Additive

“…The possible attribution can be (i) a thin SEI, (ii) the absence of ester SEI species, and (iii) the Li‐salt nature of the additive. The observation of thin and low‐impedance SEI is also recently reported for various oxide cathodes cycling in the presence of Li salt additive . The exact reason of the formation of thin SEI by the Li salt additive is not known.…”

“…Using Li salts as additives can be expected leading to SEI with good Li ion conductivity, of which many examples are recently reported to improve the efficiencies and cycling stability of LIBs and a low impedance and thin SEI (CEI) is frequently attributed for the improved performance. [27][28][29][30][31][32][33][34][35][36] However, none of these salt additive reports used LiCoO 2 as the cathode.…”

Formulation of Blended‐Lithium‐Salt Electrolytes for Lithium Batteries

“…[18,22,[25][26][27][28][29][30][31] The most intensively investigated lithium salts for lithium batteries are thermally and chemically stable lithium borates (typically lithium bis(oxalato)borate (LiBOB), lithium difluoro(oxalato)borate (LiDFOB)) and lithium imides (typically lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), lithium bis(fluorosulfonyl)imide (LiFSI)). Besides the limitation of their high cost, the two representative lithium borate salts LiBOB and LiDFOB have relatively low solubility in carbonate solvents, while the two representative lithium imide salts LiTFSI and LiFSI always cause severe anodic dissolution of the aluminum-foil cathode current collector above 4 V. Unfortunately, most newly developed lithium salts are investigated as efficient functional electrolyte additives (small dosage) [20,[32][33][34][35][36] and still can not shake the dominance of conventional LiPF 6 as the main lithium salt.…”

Free‐standing nitrogen‐doped graphene‐carbon nanofiber composite mats: electrospinning synthesis and application as anode material for lithium‐ion batteries

“…Lithium‐ion batteries (LIBs), as the significant portion of electrochemical energy storage, dominate the absolute predominant status in power source of portable electronic devices and hybrid electric vehicles . The LIBs generally consist of an electrode (cathode and anode), electrolyte, separator, and case, in which, the electrode material can have the main influence on the performance of the batteries . Graphite, as the current main anode material for commercial LIBs, still maintains some fatal deficiencies, such as a poor rate and cycle capacity, which can not meet the increasing demand of the LIBs .…”
