“…For example Al 3+ doped spinel LiMn 2 O 4 cathode exhibited excellent structural stability at elevated temperature [4][5][6][7]. Further, the VOx, ZrO 2 , Al 2 O 3 , or SiO2 coated LiMn 2 O 4 cathode exhibited interfacial stability at the elevated temperature as well and a significantly suppressed dissolution of Mn [10,11] [12,13]. In addition, 2-(triphenylphosphoranylidene) succinic anhydride was developed as an electrolyte additive to improve high temperature cycle performance of LiMn 2 O 4 /graphite Li-ion batteries due to its electrochemical decomposition and deposition on both surfaces of LiMn 2 O 4 and graphite [17].…”

“…In a fair comparison, although the initial cell impedance for the PLTB-based electrolyte was slightly higher than that of the LiPF 6 based electrolyte, the growth of cell impedance was significantly retarded. This demonstrated that the PLTB based electrolyte may effectively alleviate the decomposition of liquid electrolyte and suppress the formation of LiF on the LiMn 2 O 4 surface during high temperature cycling [12,13].…”

“…A variety of strategies have been taken to improve cycling capability of LiMn 2 O 4 based electrodes such as doping [4][5][6][7], surface coating [8][9][10][11][12][13] and functional additives in the electrolyte [1,[14][15][16][17][18][19] at elevated temperatures [20,21]. Ionic liquid-based electrolyte and single-ion-conducting nanocomposite polymer electrolytes are also very promising candidates to solve the LiMn 2 O 4 cycling problems [22][23][24].…”

a b s t r a c tThe LiMn 2 O 4 based lithium batteries using commercially available electrolytes suffer from poor cycling performance at elevated temperatures (above 55• C). This is mainly caused by the Mn dissolution generated from HF thermally decomposed from the LiPF 6 salt at elevated temperatures. In this paper, a single-ion gel polymer electrolyte (polymeric lithium tartaric acid borate @ poly(vinylidene fluoride-cohexafluoropropylene) was explored for improving the cycling performance of the LiMn 2 O 4 based lithium battery at elevated temperatures owing to superior thermal stability and comparable ionic conductivity. It was manifested that the Li/LiMn 2 O 4 cells using this single-ion gel polymer electrolyte showed stable charge/discharge voltage profiles, preferable rate capability and excellent cycling performance both at room temperature and elevated temperature of 55• C. The dissolution of metallic Mn in this electrolyte is significantly suppressed than that of LiPF 6 electrolyte. These superior performances could endow this single-ion gel polymer electrolyte a promising alternative to the conventional liquid electrolyte system in the LiMn 2 O 4 battery at elevated temperatures.

High-voltage lithium-ion batteries (HVLIBs) are considered as promising devices of energy storage for electric vehicle, hybrid electric vehicle, and other high-power equipment. HVLIBs require their own platform voltages to be higher than 4.5 V on charge. Lithium nickel manganese spinel LiNi0.5Mn1.5O4 (LNMO) cathode is the most promising candidate among the 5 V cathode materials for HVLIBs due to its flat plateau at 4.7 V. However, the degradation of cyclic performance is very serious when LNMO cathode operates over 4.2 V. In this review, we summarize some methods for enhancing the cycling stability of LNMO cathodes in lithium-ion batteries, including doping, cathode surface coating, electrolyte modifying, and other methods. We also discuss the advantages and disadvantages of different methods.
