Electrolyte
Electrolyte is the key medium of lithium ion conduction in the tower standby energy storage battery, which is responsible for providing ion channels between the positive and negative electrodes to realize the charge and discharge process of the battery. Its performance directly affects the conductivity, thermal stability and safety of the battery. The high quality electrolyte can ensure the efficient and stable operation of the battery under various working conditions.
Electrolyte
The electrolyte is an indispensable core component of the battery, and its main role is to realize the efficient conduction of lithium ions and support the charge and discharge process of the battery. By selecting high-performance lithium salts, optimizing the solvent ratio and adding functional additives, the electrolyte can improve the conductivity, chemical stability and thermal safety of the battery, thus ensuring the efficient and stable operation of the energy storage system in a variety of environments.
Main feature
Main composition
Solute (lithium salt)
Common lithium salts include lithium hexafluorophosphate (LiPF₆), which has good electrical conductivity and stability and is the most widely used lithium salt.
Other new lithium salts, such as lithium bis (trifluoromethanesulfonyl) imide (LiTFSI), offer better chemical stability and high temperature properties, but at a higher cost.
solvent
The solvent is usually a mixture of organic solvents, such as vinyl carbonate (EC), dimethyl carbonate (DMC), methyl ethyl carbonate (EMC).
These solvents have good dielectric constants and low viscosity, ensuring that lithium ions can quickly migrate and improve the conductivity of the battery.
additive
In order to improve battery performance, film-forming additives (such as VC) and antioxidants are often added to enhance the safety, cycle life and low temperature performance of the battery.
Performance characteristics
High electrical conductivity
The ionic conductivity of the electrolyte determines the speed of lithium ion transmission, and the high quality electrolyte can greatly improve the charging and discharging efficiency of the battery.
Chemical stability
Stable electrolyte can prevent decomposition, especially under high temperature or high voltage conditions, to ensure the safe operation of the battery for a long time.
Thermal stability
The high temperature resistance of the electrolyte directly affects the safety of the battery. The use of additives can improve the thermal stability of the electrolyte and reduce the risk of thermal runaway.
Low temperature performance
The high-quality electrolyte still has good electrical conductivity under low temperature conditions, ensuring the normal operation of the battery under extreme temperatures.
Effect
Ion transport
Provide ion migration channels between positive and negative electrodes to ensure smooth insertion and removal of lithium ions during battery charging and discharging.
Stabilize the internal reaction of the battery
The film forming additive in the electrolyte can form a stable solid electrolyte film (SEI film) on the surface of the negative electrode, reduce side reactions, and increase the cycle life of the battery.
Optimize battery performance
By adding specific functional additives, the electrolyte can improve the safety, low temperature performance and high rate charge and discharge capacity of the battery.
Ensure battery safety
The electrolyte with good thermal stability can effectively inhibit thermal runaway and reduce safety risks such as battery short circuit and overheating.
