“…During the initial few cycles,t he cell underwent the expected stabilization of the voltage profile ( Figure S5) owing to electrode/electrolyte interface consolidation and to the abovementioned structural reorganization of the CuO-Fe 2 O 3 -MCMB anode. As compared with state-ofthe-artL IB systems, that is, those based on graphite anodes, LiCoO 2 [64] and LiFePO 4 [65] cathodes, and the Li + insertion reaction, the voltage hysteresis observed forcells in which the conversion redoxp rocess takes place ( Figure S6) certainly represents an issue to be solved. The full-cell exhibits steady-statev oltage profiles centered at approximately 3.6 V ( Figure 5c), which reflect ac ombination of the multistep reaction of the conversion-type anode and the redox processes characteristico f the spinelc athode.…”

“…However,t he CuO-Fe 2 O 3 -MCMB/ Li 1.35 Ni 0.48 Fe 0.1 Mn 1.72 O 4 cell exhibits slight voltage hysteresis, which can be related to the voltage signature of the conversion-type anode (see Figure S6). As compared with state-ofthe-artL IB systems, that is, those based on graphite anodes, LiCoO 2 [64] and LiFePO 4 [65] cathodes, and the Li + insertion reaction, the voltage hysteresis observed forcells in which the conversion redoxp rocess takes place ( Figure S6) certainly represents an issue to be solved. Given the steady-state reversible capacityb ased on the cathode mass (110 mAh g À1 ,F igure 5d) and the average workingv oltage (3.6 V, Figure5c), we may estimate at heoretical energy density of approximately 400 Wh kg À1 for the lithium-ion cell reported herein.…”

A New CuO‐Fe₂O₃‐Mesocarbon Microbeads Conversion Anode in a High‐Performance Lithium‐Ion Battery with a Li_1.35Ni_0.48Fe_0.1Mn_1.72O₄ Spinel Cathode

A ternary CuO-Fe O -mesocarbon microbeads (MCMB) conversion anode was characterized and combined with a high-voltage Li Ni Fe Mn O spinel cathode in a lithium-ion battery of relevant performance in terms of cycling stability and rate capability. The CuO-Fe O -MCMB composite was prepared by using high-energy milling, a low-cost pathway that leads to a crystalline structure and homogeneous submicrometrical morphology as revealed by XRD and electron microscopy. The anode reversibly exchanges lithium ions through the conversion reactions of CuO and Fe O and by insertion into the MCMB carbon. Electrochemical tests, including impedance spectroscopy, revealed a conductive electrode/electrolyte interface that enabled the anode to achieve a reversible capacity value higher than 500 mAh g when cycled at a current of 120 mA g . The remarkable stability of the CuO-Fe O -MCMB electrode and the suitable characteristics in terms of delivered capacity and voltage-profile retention allowed its use in an efficient full lithium-ion cell with a high-voltage Li Ni Fe Mn O cathode. The cell had a working voltage of 3.6 V and delivered a capacity of 110 mAh g with a Coulombic efficiency above 99 % after 100 cycles at 148 mA g . This relevant performances, rarely achieved by lithium-ion systems that use the conversion reaction, are the result of an excellent cell balance in terms of negative-to-positive ratio, favored by the anode composition and electrochemical features.

“…In the investigative voltage range, the potential at the rapid increasing stage of current is considered as the upper limitation of electrochemical stability of electrolyte. The decomposition voltage of (CSLC-x)GPEs (x = 0, 5, 10,15,20) are basically stable at 4.8 V (The electrochemical stability window of Celgard2400 with liquid electrolyte is around 4.5 V.

“…[18,19] GPE is usually regarded as a kind of electrolyte between SPE and LE. Compared to SPE, GPE has higher ionic conductivity at room temperature, which reaches up to 10 À 3 S cm À 1 , [20][21][22][23][24][25] a value that is close to LE.

A new gel polymer electrolyte (GPE) based on chitosan‐lignocellulose composites with a smooth and porous structure for applications in lithium‐ion batteries was prepared. The obtained GPE matrix and GPE show excellent comprehensive performances. The GPE matrix based on the composite containing 15 % chitosan (denoted CSLC‐15) had the best performance, with liquid electrolyte uptake of up to 749.1 wt %. The ionic conductivity for corresponding GPE is 2.89 mS cm−1 at room temperature, and the lithium ion transference number is 0.90. The GPE proved promising for use in lithium‐ion batteries, offering a large electrochemical window (4.8 V) and excellent interfacial compatibility (a stable impedance value of 227.97 Ω after 30 days). Moreover, the GPE shows excellent thermal and mechanical properties, and high C‐rates capability (163.13 mAh g−1, 152.53 mAh g−1, 144.27 mAh g−1, 128.45 mAh g−1, 156.12 mAh g−1, at 0.2 C, 0.5 C, 1.0 C, 2.0 C, 0.2 C, respectively) and cycle performance (161.99 mAh g−1 at the 99th cycle of 0.2 C), which proved its suitability of use in lithium‐ion batteries.

“…Other recent studies reported the use of carbonaceous anode materials in combination with LFP cathodes with promising results. 45,[104][105][106][107] Several advantages in terms of cycle life and safety content may be achieved by using LFP in combination with titanium oxide based anodes, e.g., TiO2 and Li4Ti5O12 (LTO). Furthermore, titanium is the ninth most abundant element in the Earth's crust and Ti-based oxides are environmentally benign 108.…”
