1. Overview of Longenerg lead-acid battery

As a common chemical power source, lead-acid batteries are widely used in many fields. Longenerg lead-acid batteries also have the basic characteristics of lead-acid batteries, and they can play an important role in the automotive, industrial, commercial and marine fields. For example, in the automotive field, it can be used as a starting, lighting and ignition (SLI) battery to power the car's starting and electrical equipment. Lead-acid batteries are generally composed of positive and negative plates or grids, which are usually made of lead or lead alloys and include multiple wires connected to multiple nodes. Longenerg lead-acid batteries are no exception, and their plate structure design helps to improve battery performance and stability.

2. Active materials of Longenerg lead-acid batteries

The active materials in Longenerg lead-acid batteries play a critical role in battery performance. In lead-acid batteries, a paste material is applied to at least a portion of the positive grid or plate. The paste typically comprises lead oxide (PbO), and the active materials may also include one or both of tetrabasic lead sulfate (4PbO·PbSO4, often abbreviated as "4BS") and tribasic lead sulfate (3PbO·PbSO4·H2O, often abbreviated as "3BS"). Different active material compositions can have varying effects on battery performance. For example, in some embodiments, the active material may comprise approximately 40% PbO and 60% 4BS; other compositions, such as approximately 10% to 100% 4BS, are also possible. The tetrabasic and tribasic lead sulfates may be provided in the form of single crystals incorporated into the lead oxide paste material. Under appropriate mixing and plate curing conditions, the tetrabasic and tribasic lead sulfates can be produced by adding an acid to the paste mixture. The cured positive plates comprising tetrabasic lead sulfate as a component of the paste coated thereon have improved deep discharge cycle life compared to cured positive plates using tribasic lead sulfate as a component in the paste.

3. Manufacturing process of Longenerg lead-acid battery

The manufacturing process for Longenerg lead-acid batteries involves multiple steps. First, the plates are made of lead or lead alloys. The manufacturing process requires precise control of the alloy composition and ratio to ensure plate performance. During plate manufacturing, the lead or lead alloy is processed into specific shapes and structures, such as a structure with multiple wires connecting to multiple nodes. Next, the active material is prepared. Lead oxide, tetrabasic lead sulfate, and tribasic lead sulfate are mixed according to specific proportions and processes to form a paste, which is then applied to the plates. Next, the plate curing process involves solidifying or drying the paste-coated positive plates to remove excess liquid. During the curing process, the tetrabasic lead sulfate and/or tribasic lead sulfate crystals grow or increase in size. Finally, the battery is assembled. The cured plates are placed in the battery container, a separator is placed between the positive and negative plates, and an acid (such as sulfuric acid) is added. Parameters at each step of the entire manufacturing process must be strictly controlled to ensure battery quality and performance.

4. Application cases of Longenerg lead-acid batteries

Longenerg lead-acid batteries have practical application cases in various fields. In the automotive industry, they provide reliable power support for the vehicle's starting, lighting, and ignition systems. Many automakers choose Longenerg lead-acid batteries as standard equipment in their vehicles because of their excellent starting performance and stability. In the industrial field, Longenerg lead-acid batteries can be used in uninterruptible power supply (UPS) systems to provide backup power for important equipment and data centers, ensuring normal operation of equipment in emergencies such as power outages. In the marine field, they can power a ship's electrical equipment and navigation systems, ensuring safe navigation. For example, a large shipping company uses Longenerg lead-acid batteries on its ships. After long-term use and practical testing, the batteries can still perform stably in harsh marine environments, providing strong support for the normal operation of the ship.

5. Maintenance and care of Longenerg lead-acid batteries

To ensure the performance and lifespan of Longenerg lead-acid batteries, proper maintenance and care are essential. Regularly inspect the battery's exterior for damage, leakage, and other signs of damage. Check the battery fluid level; if it's too low, add distilled water immediately. Also, pay attention to battery charging and discharging to avoid overcharging and over-discharging. Overcharging can cause problems such as overheating and water loss, shortening the battery lifespan; over-discharging can cause sulfation of the battery plates, reducing the battery's capacity. Furthermore, regular charge and discharge tests are required to monitor battery performance. If deterioration is detected, repair or replacement is necessary. For example, a company's backup power system uses Longenerg lead-acid batteries. Thanks to regular maintenance and care, the battery's lifespan has been extended by 20% beyond expectations, saving the company money.

6. Development prospects of Longenerg lead-acid batteries

With the continuous advancement of technology and changing market demands, Longenerg lead-acid batteries are facing new development opportunities and challenges. Amid the rapid development of new energy vehicles, lead-acid batteries face competition from other battery technologies, such as lithium batteries. However, due to their advantages, such as low cost, high safety, and mature recycling technology, they still play an irreplaceable role in certain specific applications. For example, in low-speed electric vehicles and electric bicycles, lead-acid batteries still hold a large market share. At the same time, Longenerg is continuously increasing its R&D investment to improve the performance of lead-acid batteries, enhancing their energy density, cycle life, and other indicators. For example, by developing new active materials and manufacturing processes, Longenerg lead-acid batteries are better able to meet market demand. In the future, Longenerg lead-acid batteries are expected to play a greater role in energy storage, supporting the large-scale application of renewable energy. For example, in renewable energy generation systems such as solar and wind power, lead-acid batteries can serve as energy storage devices, storing excess electricity and releasing it when needed, thereby improving energy efficiency.
