“…The C dl decreases gradually as lithium ion intercalates into LiMnPO 4 and then reaches to a minimum value of 1 mF at E SCE =−0.60 V. Subsequently, the value of C dl increases gradually. A similar type of trends in the variations of kinetic parameters have been reported for LiV 3 O 8 [31] and LiCoO 2 [32] lithium insertion materials in aqueous lithium electrolytes.…”

A study of the electrochemical behavior of LiMnPO 4 prepared by RAPET method in different aqueous electrolytes using cyclic voltammetry (CV), galvanostatic charge-discharge experiments, and electrochemical impedance spectroscopy is reported. CV peak current is proportional to the square root of scan rate under 0.2 mV s −1 . The system satisfied the required conditions for a reversible system with a resistive behavior. LiMnPO 4 was found to undergo proton insertion at lower concentrations of electrolyte. At higher concentrations or saturated solutions of electrolytes, lithium insertion/de-insertion becomes the main reaction though the effect of proton insertion/de-insertion reaction cannot be ignored. Electrochemical insertion/deinsertion of lithium in LiMnPO 4 was studied using EIS technique. The kinetic parameter, charge transfer resistance (R ct ), obtained by simulating the experimental impedance data with an equivalent circuit showed a minimum at the potential close to the CV peak potential. The cell LiTi 2 (PO 4 ) 3 /5 MLiNO 3 /LiMnPO 4 delivers a discharge capacity of 84 mAh g −1 in the first cycle at an applied current of 0.2 mA cm −2 and it retains its initial capacity over 50 cycles with good rate capability.

“…By using inexpensive salt solution as electrolyte, aqueous rechargeable lithium battery (ARLB) can fundamentally settle the safety issues and also avoid rigorous assembly conditions. Moreover, ARLB is far more environmental friendly compared with non-aqueous LIBs and the ionic conductivity of electrolyte can be increased by several magnitudes5.…”

Poor cycling performance arising from the instability of anode is still a main challenge for aqueous rechargeable lithium batteries (ARLB). In the present work, a high performance LiTi2(PO4)3/C composite has been achieved by a novel and facile preparation method associated with an in-situ carbon coating approach. The LiTi2(PO4)3/C nanoparticles show high purity and the carbon layer is very uniform. When used as an anode material, the ARLB of LiTi2(PO4)3/C//LiMn2O4 delivered superior cycling stability with a capacity retention of 90% after 300 cycles at 30 mA g−1 and 84% at 150 mA g−1 over 1300 cycles. It also demonstrated excellent rate capability with reversible discharge capacities of 115 and 89 mAh g−1 (based on the mass of anode) at 15 and 1500 mA g−1, respectively. The superior electrochemical properties should be mainly ascribed to the high performance of LiTi2(PO4)3/C anode, benefiting from its nanostructure, high-quality carbon coating, appropriate crystal structure and excellent electrode surface stability as verified by Raman spectra, electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD) and scanning electron microscopy (SEM) measurements.
