Theoretical Assessment of the First Cycle Transition, Structural Stability and Electrochemical Properties of Li2FeSiO4 as a Cathode Material for Li-ion Battery

Lithium iron orthosilicate (Li2FeSiO4) with Pmn21 space group is theoritically investigated as a chathode material of Li-ion batteries using density functional theory (DFT) calculations. PBE-GGA (+USIC), WC-GGA, L(S)DA (+USIC) and mBJ+LDA(GGA) methods under spin-polarization ferromagnetic (FM) and anti-ferromagnetic (AFM) procedure are used to investigate the material properties, includin...

Synthesis and Characterization of LiMnPO4/Carbon Nanocomposite Material as Cathode Material

Development of an eco-friendly, low cost and high energy density LiMnPO4 cathode material has attracted much attention due to its high operating voltage vs. Li falling within the electrochemical stability window of conventional electrolyte solutions and offers more safety features due to the presence of a strong P-O covalent bond.Synthesis of battery materials integrates the...

New Type of Alkaline Rechargeable Battery—Ni-Ni Battery

The feasibility of utilizing disordered Ni-based metal hydroxide, as both the anode and the cathode materials, in alkaline rechargeable batteries was validated for the first time. Co and Mn were introduced into the hexagonal Ni(OH)2 crystal structure to create disorder and defects that resulted in a conductivity increase. The highest discharge capacity of 55.6 mAh ̈g ́1 was obtained using a comme...

High-capacity battery cathode prelithiation to offset initial lithium loss

Loss of lithium in the initial cycles appreciably reduces the energy density of lithium-ion batteries. Anode prelithiation is a common approach to address the problem, although it faces the issues of high chemical reactivity and instability in ambient and battery processing conditions. Here we report a facile cathode prelithiation method that o ers high prelithiation e cacy and good compatibili...
