Core component
The performance and stability of tower backup energy storage battery cannot be separated from the synergistic action of each core component. Among them, "positive electrode material", "negative electrode material", "electrolyte", "diaphragm" and "shell material" are the important basis of the battery system, which directly affect the energy density, cycle life, safety and overall performance of the battery.
Core component
Anode materials, anode materials, electrolyte, diaphragm and shell materials are the core components of energy storage batteries, which together determine the energy storage capacity, cycle life and safety performance of the battery. By optimizing the material properties of each component, the battery system can achieve higher energy density, longer service life and more stable operation results to meet the needs of a variety of application scenarios.
Main materials include
Function: The positive electrode material is the main active material for energy storage battery to release and store energy, which directly determines the energy density and operating voltage of the battery.
Common materials: lithium battery cathode materials mainly include lithium iron phosphate, nickel cobalt manganese ternary material (NCM) and lithium manganate. Lithium iron phosphate is known for its high safety and long life, and is suitable for energy storage.
Performance advantage: High quality cathode material has high specific capacity, good thermal stability and long life characteristics, to ensure the efficient and stable operation of the battery.
Function: As the carrier of lithium ion embedding and release, the negative electrode material directly affects the charge and discharge speed and cycle life of the battery.
Common materials: The commonly used anode material is graphite (carbon material), but there are also emerging materials such as silicon-carbon composites, which have the potential for higher energy density.
Performance advantage: high conductivity, low expansion rate of the negative electrode material can improve the battery charging and discharging efficiency, while reducing the internal impedance of the battery, extend the service life.
Function: Electrolyte is the medium of lithium ion transmission inside the battery, ensuring the rapid migration of ions between the positive and negative electrodes to achieve the battery charging and discharging process.
Common materials: Mixtures of lithium salts (such as lithium hexafluorophosphate) and organic solvents, with high electrical conductivity and stability.
Performance advantage: high-quality electrolyte has good chemical stability and thermal stability, to ensure the safe operation of the battery under high and low temperature conditions.
diaphragm
What it does: The diaphragm separates the positive and negative electrodes of the battery, preventing short circuits while allowing lithium ions to pass freely through the electrolyte.
Common materials: Usually made of polymer materials (such as polyethylene, polypropylene), with a microporous structure.
Performance advantages: High-quality diaphragm with high transmittance and thermal stability, maintaining structural integrity at high temperatures and ensuring battery safety.
Function: The shell material provides physical protection for the battery, prevents the external environment from affecting the internal material of the battery, and improves the structural stability of the system.
Common materials: Metal materials (such as aluminum alloy, stainless steel) and engineering plastics, with good strength and sealing.
Performance advantage: The shell material should be waterproof, dustproof and corrosion resistant, and protect the stable operation of the battery in harsh environments.
