What is the density of LiCoO2?
What is the density of LiCoO2?
4.79 g/cm3
The density of the specimen is 4.79 g/cm3, corresponding to a high relative density ∼95% (theoretical density: 5.05 g/cm3) [10].
How do you find theoretical energy density?
The energy density of a battery can be simply calculated using this formula: Nominal Battery Voltage (V) x Rated Battery Capacity (Ah) / Battery Weight (kg) = Specific Energy or Energy Density (Wh / kg).
How do you calculate theoretical capacity?
Divide the molar electrical capacity: 26,800 mAh/mol by the molecular weight of the material of interest, and multiply by number of exchanged electrons. And you will get the Theoretical specific capacity of that material. This is a simple way to compute theoretical specific capacity.
How do you find the energy density of a lead acid battery?
Theoretical specific energy for lead-acid batteries = 83A/kg x 2.046V = 169.82Wh/kg.
What is the structure of LiCoO2?
The layered LiCoO2 structure has hexagonal symmetry and belongs to the space group R-3m. However, with this particular structure, there are two possible positions for the metal ions (Li+) and the transition metal ions (Co3+) to occupy, that is, the 3a and 3b Wyckoff positions.
Is LiCoO2 a solid?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). . Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, and is commonly used in the positive electrodes of lithium-ion batteries. …
What is theoretical capacity?
Theoretical capacity is the level of a manufacturer’s production that would be attained if all of its equipment and operations performed continuously at their optimum efficiency. Theoretical capacity is also referred to as ideal capacity.
What is the specific capacity of the lifepo4 positive electrode?
The specific capacity of commercially available cathode carbon-coated lithium iron phosphate is typically 120–160 mAh g−1, which is lower than the theoretical value 170 mAh g−1.
What is the theoretical energy density of this battery?
The energy density required for rechargeable batteries to power 300-mile range electric vehicles on a single charge is about 600 Wh/kg. Li-ion batteries are unable to meet this need in the foreseeable future.
What is the theoretical specific capacity in AH G for lead acid battery?
Typical values range from 0.26 Ah/g for Pb to 26.59 Ah/g for H2. The energy density is the energy that can be derived peer unit volume of the weight of the cell. The specific energy density is the energy that can be derived per unit weight of the cell (or sometimes per unit weight of the active electrode material).
What is the maximum theoretical capacity?
Theoretical maximum capacity is given by, C = 1000 V S. Where, C = is capacity is vehicle/hr. V = speed in km/hr.
What is the specific capacity of LiCoO2?
Although the theoretical specific capacity of LiCoO 2 is as high as 274 mAh g −1, the superior electrochemical performances of LiCoO 2 can be barely achieved due to the issues of severe structure destruction and LiCoO 2 /electrolyte interface side reactions when the upper cutoff voltage exceeds 4.5 V.
What is the composition of LiCoO2 electrode?
LiCoO2 electrode was prepared by coating the N-methyl pyrrolidone (NMP)-based slurry containing LiCoO2 (80 %), PVDF (10 %) a […] Explore more synthesis descriptions for materials of composition LiCoO2. How do we arrive at this value? For more detail, pelase see the Total Energy Adjustments section of our Calculations Guide. Loading…
What happens to LiCoO2 when it is fully lithiated?
In the fully lithiated state, LiCoO 2 remains in layered structures with hexagonal unit cells. With removal of Li from the layered crystal lattice (during charging), nonstoichiometric Li 1-x CoO 2 compounds are formed and the oxidation of Co 3+ changes for charge compensation.
What is the relative density of LCO powder?
As-received LCO powders (EQ-Lib-LCO, MTI, California, USA) were cold-pressed into billets (12.7 mm diameter 4.0 mm thick) at room temperature in a stainless steel die at ∼385 MPa to obtain a green relative density ∼60%.
