What is a negative electrode?
Lithium iron phosphate batteries are widely used in electric vehicles and energy storage systems due to their safety, long cycle life and thermal stability. The negative electrode is an important part of the battery, and its material and function directly affect the battery performance.
The cathode material is mainly graphite, including natural and artificial graphite, with good electrical conductivity and electrochemical stability. In addition, silicon-based materials have been studied due to their high theoretical capacity, but have not been widely used due to volume expansion problems and are often compounded with graphite. The addition of composite materials and conductive agents and binders can further improve the performance.
Lithium ion storage: Provide lithium ion storage space to complete the charging and discharging process.
Electrochemical reactions: participate in reactions and affect energy density and efficiency.
Conductivity: to ensure current conduction, help to improve the battery power output.
Structural stability: maintain the stability of the material structure in multiple cycles and extend the service life of the battery.
Conclusion
The negative electrode is the key to the performance of lithium iron phosphate batteries, and future research on new materials is expected to improve the energy density and cycle stability of batteries, and promote the development of electric vehicles and energy storage systems.
