The stacker is one of the key equipment for the production of square lithium batteries. Generally consists of ten institutions: unwinding mechanism, positive electrode material box, negative electrode material box, positive electrode secondary positioning mechanism, negative electrode secondary positioning mechanism, positive electrode feeding mechanism, negative electrode feeding mechanism, stacking table, pasting mechanism, Blanking mechanism。 Material agency.(Cutting and stacking Integrated machine)   

The gap between the upper and lower blades, the gap between the pressing plate and the punch, the pressure of the pressing plate and the flatness of the pressing plate surface are the major factors that affect the powder drop. To ensure the gap between the various parts of the mold, firstly, the mold material must be selected, and secondly, the machining accuracy must be ensured.        a: The gap between the upper and lower blades: When the gap is small, the punching force on the pol

When it comes to battery balancing, it has basically touched the core area of ​​BMS. First of all, it is necessary to understand a few issues. 1. There is a limit to battery balancing, and the effect should be evaluated with certain parameters. 2. Battery balance In HEV and EV, the requirements are very different. 3. The effect of battery balancing must be a game and compromise with cost and additional energy consumption. Reason for balance: Both EVs and HEVs have to withstand large instantaneous curre

The automatic battery charger circuit design in this article employs what is arguably the simplest window comparator ever made with a single transistor (see figure). It starts charging when the voltage drops below a predetermined value and stops charging when the voltage exceeds a predetermined value. With an accurate variable voltage power supply, the voltage can be set up or down. The normally connected relay leads are not connected to the 15Vdc power supply, which prevents voltage from passing to the battery

Today, Texas Instruments (TI), leveraging its strong R&D strength in battery management, announced a unique "Gas Gauge" technology that can calculate lithium-ion battery packs with up to 99% accuracy over the entire battery life cycle of remaining power. The new ImpedanceTrack™ technology enables designers and users of portable medical equipment, industrial equipment and notebooks to extend battery life and always know the available energy remaining in the battery. Taking battery fuel monitor

In life, you may have come into contact with various electronic products, so you may not know some of its components, such as the energy storage battery it may contain, then let Xiaobian lead you to learn energy storage technology together . Energy storage devices composed of energy storage elements and grid access devices composed of power electronic devices have become two important parts of energy storage systems. Energy storage devices are important for enabling energy storage, release or fast power exchange. T

In 1839, fuel cell technology was introduced. In the 1970s, the oil crisis caused an energy panic, and hydrogen energy, as an emerging clean energy source, began to attract the attention of governments around the world. In the 1990s, internationally renowned car companies including Ford and Mercedes-Benz launched fuel-powered cell concept models. After entering the 21st century, the development of hydrogen energy and fuel power cell technology has gradually matured. In the past two years, due to the advantages of h

Lithium-ion battery pack is a product of lithium-ion batteries in series or in series, which is very common in our daily life. To put it bluntly, the balance is to maintain all lithium-ion battery packs in all normal areas to ensure overall safety. Why do lithium-ion battery packs have to be balanced? Lithium-ion battery packs are generally composed of one or several lithium-ion battery packs connected in series, and each lithium-ion battery pack is composed of three to four series-connected batteries. The integ

1. High specific energy electrolyte The pursuit of high specific energy is the biggest research direction of lithium-ion batteries at present, especially when mobile devices account for more and more in people's lives, battery life has become the most critical performance of batteries. 2. High-power electrolyte At present, it is difficult for commercial lithium-ion batteries to achieve high-rate continuous discharge. The important reason is that the battery tabs are seriously heated, and the internal resis
