Problem Statement
- Mesoporous LiFePO4/C composite is used as cathode materials in Li-ion batteries due to its high surface area and superior textural properties.
- Common carbon sources include citric acid, glucose, and sucrose for uniform coating.
- A one-pot synthesis of ordered mesoporous LIP/MNC-31 composite was achieved using a nanocasting approach and high-temperature calcination in an inert atmosphere, resulting in a metal-free high-surface-area nitrogenous composite.
- A liquid co-precipitation method for producing LiFePO4/CRF nano composite as a positive electrode material, overcoming cumbersome methods and long experimental duration.
- An improved method for synthesizing ordered mesoporous LiFePO4/N-doped Carbon (LIP/MNC-31) composite using a nano-casting technique is needed, as well as for synthesis as superior cathode material for high-performance Li-ion batteries.
Technology
Method:
- Synthesis of ordered mesoporous LiFePO4/N-doped Carbon (LIP/MNC-31) composite as superior cathode material for high performance Li-ion batteries
- Adding 5g of PVP (polyvinylpyrollidone) in 20 mL of dichloromethane and vigorously stirred for 1 h at 303 K;
- Adding and stirring SBA-15 for 6 h at room temperature and placing the mixture in a drying oven at 343 K for 6 h;
- Carbonization of mixture by pyrolysis at preferred temperatures in the range of 873 – 1273 K (preferably at 1173 K) for 6 h with a heating rate of 5.0°C min-1
- under inert gas flow wherein the resulting carbon/silica composite can be dissolved in 15 wt% HF at room temperature, in order to remove the silica.
Key Features / Value Proposition
- Good reversibility and enhanced specific capacity.
- Novel ordered nitrogenous mesoporous carbon (MNC-31) as hard template.
- Lithium foil used as both the reference and counter electrode.
- superior cathode material for high-performance Li-ion batteries.
