Pyrite (FeS₂) is a common mineral that has good electrical conductivity and chemical stability in its powder form. The electrical conductivity of pyrite powder comes from its rich electronic structure, which gives it good electrical conductivity and ionic conductivity in battery applications. In addition, the abundance and low cost of pyrite powder also make it an ideal conductive material.
better conductivity
In lithium iron batteries, the selection of conductive materials is crucial to the battery's charge and discharge performance. Research shows that adding an appropriate amount of pyrite powder can significantly improve the conductivity of electrode materials. One study pointed out that when the amount of pyrite powder added was 5%, the conductivity of the electrode increased by about 30%.
better energy density
Pyrite powder not only increases electrical conductivity but also improves the overall energy density of the battery. Experimental data shows that the energy density of iron-lithium batteries using pyrite powder can reach 150 Wh/kg, while the energy density of batteries with traditional conductive materials is only 130 Wh/kg.
Improved cycle life
Cycle life is a key factor affecting the practical application of batteries. Research has found that batteries using pyrite powder have a capacity retention rate of more than 90% after 500 charge and discharge cycles, while batteries with traditional conductive materials have a capacity retention rate of only 75%. This performance improvement makes lithium iron batteries perform better in long-term use.
Pyrite powder's good conductivity, increased energy density and long cycle life make it an important direction for the future development of iron-lithium batteries.
