At the Institute of Physics of Kazan Federal University (KFU), the properties of a new material, an organic triazine framework, were studied. It is planned to be used to improve modern metal-ion batteries. This was reported by the press service of the Ministry of Education and Science of Russia.
Modern lithium-ion batteries have high energy density and a long service life. The new material can be used for the anode electrode in such batteries.
Covalent triazine frameworks have a number of advantages. Their molecular structures can be easily modified — they are light, flexible and environmentally friendly, and they are also potentially cheap.
The researchers applied a universal density functional method to analyze the mechanical and thermodynamic stability, strength, and theoretical capacity of the new material.
The results showed that a silicon- and fluorine-doped covalent triazine framework provides high capacitance characteristics and stable operation during charging and discharging. The theoretical capacity of the new material is 462 mAh/g. This figure significantly exceeds the capacity of graphene (372 mAh/g).
