OPzV solid state lead battery is suitable for the renewable energy storage system in the environment with large temperature difference, unstable power grid or long-term power shortage. OPzV solid state lead battery allows users to have more autonomy, allowing the battery to be installed on the cabinet or rack, even next to office equipment. Thus, the space utilization rate is improved, and the installation and maintenance costs are reduced.

The increase of fine fiber content in the partition fiber ratio will improve the appearance performance, increase the liquid absorption, increase the penetration speed, and reduce the maximum pore diameter, which is beneficial to the partition.

In order to prolong the cycle life of PE battery separator, it is necessary to ensure that the plate is always in a compressed state during the battery cycle. The separator of PE battery will shrink after the battery is filled with acid or the battery is dehydrated, and the contraction of the separator reduces the pressure between the plates, thus shortening the cycle life of the battery. The bonding force between superfine glass fibers in the separator of PE battery is very small. When the surface tension of water is greater than the bonding force between fibers, the bonding force between superfine glass fibers will be destroyed; The elasticity of the superfine glass fiber in the separator of PE battery is not good enough, so that it cannot be restored to its original state after being compressed.

Battery discharge current. Generally speaking, it is the discharge rate. There are time rate and current rate for the discharge current of the battery. Discharge time rate refers to the length of time from discharge to termination voltage under certain discharge conditions. According to IEC standards, the discharge rates are respectively 20 hour rate, 10 hour rate, 5 hour rate, 3 hour rate, 2 hour rate, 1 hour rate, 0.5 hour rate, etc. The rated capacity of the battery is expressed in C. The capacity of the battery obtained at different discharge rates will be different.

The health state of the battery is expressed by SOH, which is the full name of State of Health. If the battery is regarded as a container for storing electricity, SOC refers to how much available electric energy is stored in the container at a certain time (available electric energy here refers to the electric energy that can be used through discharge), while SOH is generally understood as how much the volume (not physical volume) of the container for storing available electric energy remains, that is, how much available electric energy it can store.

The electrolyte of valve regulated lead acid battery is in a lean state, that is, most of the electrolyte is adsorbed in the superfine glass fiber membrane, and the rest is absorbed by the electrode plate. In order to ensure that oxygen can diffuse to the negative electrode smoothly, the active substances of the membrane and electrode plate are required not to be saturated by the electrolyte, otherwise it will block the oxygen passage through the membrane, affecting the reduction of oxygen on the negative electrode. In order to make the chemical reaction go on normally, the active substance on the electrode plate must be fully contacted with the electrolyte, while the battery with electrolyte poor structure can only achieve this purpose by tight assembly.

Under the same specification, the volume of lithium iron phosphate battery is only half of that of lead-acid battery, and the weight is only 35% of that of lead-acid battery. Theoretically, the space is completely enough. However, it is necessary to consider whether it can still be installed in the original position, and whether it protrudes or is squeezed.

The AGM separator shall be selected based on its own performance. According to the analysis of the function of the separator in the battery, the AGM separator shall have high acid absorption capacity, small shrinkage after acid absorption, reasonable microporous structure and low resistivity. According to the comprehensive performance requirements of the battery, the AGM separator should also have the characteristics of low impurity content, high tensile strength, fast infiltration speed, etc.
