The lead-acid battery is used as an electric forklift power supply, and is also a key support for electric forklifts. The capacity and cycle life of the battery is an important indicator for measuring the performance of the battery. The capacity and cycle life of the tubular forklift battery is mainly dependent on the positive electrode plate, and the positive electrode plate of the traction power battery is usually used.The structure of the tubular positive plate is based on a skeleton skeleton, which is designed to be a plurality of lead-resistant sleeves. One of the main features is to use a sleeve to fix the active substance, which is closely bonded to the positive plate gate lead to prevent the active substance from falling off. This requires the sleeve to have acid resistance and corrosion resistance, and have a certain porosity to facilitate electrolyte and ionic self-migration. Second, the gate lead alloy skeleton of the tubular positive plate is surrounded by the active substance, its corrosion rate is also slower, and the battery life can be extended.
The experimental data proves that the diameter is 3.0-3.5 mm skeleton tube positive electrode plate, the number of charge and discharge cycles can reach around 1200 times, the current ?GB7403.1-2008 traction lead-acid battery" national standard, the cycle of battery cells The specified value reaches 800 times.
The paste plate having the same thickness, since the positive electrode plate active material is easily detached, only 500 times. Third, the mass fraction of the residual lead in the coated polar plate is reduced to 2.5% by curing, and the cure of the tubular positive electrode plate is reduced to 2.0%, so that the initial capacity of the battery is improved.
In tubular batteries, the tube positive electrode plate is its core component, the casing of the positive plate is the foundation, and more commonly used casing has three types of glass wire tubes, polyester tube and non-woven discharge. Since the polyester pipe has the advantage of long-term resistance, high heterogenesis, high tube wall, thin weight, convenient operation, and high cost performance, with increased use, polyester pipe The impact on battery life is also growing, of which corrosion penetration is a major factor, and the problem is also very important for the in-depth analysis and verification of polyester pipe.
