Introduction

In the field of modern logistics and industrial production, forklifts, as key material handling equipment, their efficient and stable operation is of vital importance. The power core of a forklift - the battery - plays a decisive role in its performance. Lead-acid batteries have occupied an important position in the field of forklift power due to their significant advantages such as low cost, mature technology, high safety and a complete recycling system. With the continuous increase in the industry's requirements for the operational efficiency and endurance of forklifts, the long-lasting power technology of high-performance forklift lead-acid batteries has become a research focus. A thorough analysis of this technology is of great significance for promoting the development of the forklift industry and enhancing the efficiency of logistics and industrial production.

The key factors affecting the power durability of lead-acid batteries

Plate materials and structures

As the core site of electrochemical reactions, the materials and structures of the plates have a profound impact on the persistence of dynamic energy. During the charge and discharge cycles, traditional plate materials are prone to problems such as the shedding of active substances on the positive plate and the sulfation of the negative plate, which leads to battery capacity attenuation and power decline. For instance, during long-term use, the structure of the lead dioxide crystal on the positive plate will gradually become loose, the bonding force between the active material and the grid will weaken, leading to detachment, reducing the effective substances involved in the reaction and lowering the battery capacity. The structural design of the plates, such as the shape, thickness and pore size distribution of the grid, affects current conduction and electrolyte diffusion. A reasonable grid design can reduce resistance, improve current transmission efficiency, promote uniform penetration of the electrolyte, and enhance the overall performance of the battery.

Electrolyte performance

The electrolyte plays a crucial role in ion conduction in lead-acid batteries, and its concentration, purity and stability are directly related to the battery's power durability. An appropriate concentration of sulfuric acid can ensure the efficient progress of electrochemical reactions. Both excessively high and low concentrations will affect the reaction rate and battery capacity. For example, if the concentration of sulfuric acid is too high, it will accelerate the corrosion of the plates and shorten the battery life. If it is too low, the reactivity will be reduced, resulting in insufficient power. Impurities in the electrolyte can trigger side reactions, consume active substances and reduce battery performance. Meanwhile, during the charging and discharging process, the electrolyte will undergo composition changes due to reasons such as water evaporation and sulfuric acid decomposition, which affects the stability and power durability of the battery.

Battery design and manufacturing process

The overall design of the battery, including the capacity configuration of the battery, the connection method between individual batteries, heat dissipation and ventilation design, etc., has a significant impact on the power durability. A reasonable capacity configuration should be matched with the actual working requirements of the forklift to avoid excessive discharge or insufficient charging. The connection between individual batteries should ensure low resistance, high reliability and reduce energy loss. Good heat dissipation and ventilation design can effectively control the working temperature of the battery, preventing problems such as plate deformation and electrolyte drying up due to excessive temperature, which would affect the battery's lifespan and power output. The precision and consistency of the manufacturing process are also of vital importance. The uniformity of the plate coating and the tightness of the separator installation will all affect the electrochemical reactions inside the battery, and thereby influence the power endurance.

Advanced technologies for enhancing the long-lasting power of lead-acid batteries

Research and development of new plate materials

To improve the performance of the plates, researchers are constantly exploring new types of plate materials. For instance, new carbon materials such as carbon nanotubes and graphene can be introduced into the positive plate. By taking advantage of their high electrical conductivity and excellent mechanical properties, the bonding force between the active material and the grid can be enhanced, the shedding of the active material can be reduced, and the cycle life and power endurance of the battery can be improved. In terms of the negative plate, using multi-alloy materials such as lead-calcium alloy and lead-tin alloy to replace the traditional pure lead grid can effectively suppress the sulfation of the negative plate, improve the charging and discharging efficiency and low-temperature performance of the battery. Some studies have improved the anode reaction kinetics, enhanced the battery's anti-sulfation ability and prolonged the battery's service life by adding nano-scale additives, such as nano-zinc oxide and nano-tin oxide, to the anode active material.

Electrolyte optimization technology

A variety of technical means have been developed for optimizing the performance of the electrolyte. High-purity sulfuric acid raw materials are adopted, and impurities are removed through advanced purification processes to reduce the occurrence of side reactions and improve the stability of the electrolyte. The development of new electrolyte additives, such as stannous sulfate and boric acid, can improve battery performance without changing the main components of the electrolyte. Stannous sulfate can inhibit sulfation of the negative plate, and boric acid can enhance the buffering capacity of the electrolyte, stabilize the pH value of the electrolyte, reduce plate corrosion, and improve the cycle life and power durability of the battery. In addition, by adjusting the concentration and density of the electrolyte to be compatible with the battery's working environment and charging and discharging system, the battery performance can be further optimized.

Improvement of battery structure and manufacturing process

In terms of battery structure design, a compact and lightweight design concept is adopted. Under the premise of ensuring battery performance, the volume and weight of the battery are reduced to enhance the effective load capacity and energy utilization efficiency of the forklift. In terms of manufacturing processes, advanced automated production equipment and high-precision detection technologies have been introduced to ensure the accuracy and consistency of the plate coating, assembly and other links. Adopting the internalization process instead of the traditional externalization process can enable the active substances on the plates to form a more uniform and stable structure, improving the performance and consistency of the battery. Meanwhile, optimize the sealing process of the battery to reduce the leakage of the electrolyte and the evaporation of water, and extend the service life of the battery.

Conclusion

The long-lasting power technology of high-performance forklift lead-acid batteries is a complex system involving multiple aspects such as plate materials, electrolyte, battery structure and manufacturing process. Through continuous research and development of new plate materials, optimization of electrolyte performance, and improvement of battery structure and manufacturing processes, remarkable achievements have been made. This has effectively enhanced the power endurance of lead-acid batteries and met the forklift industry's demand for efficient and stable power. With the integration of intelligent management and monitoring technologies, the coordinated development with new energy technologies, and the pursuit of green environmental protection and sustainable development, the long-lasting power technology of high-performance forklift lead-acid batteries will continue to innovate and break through, injecting strong impetus into the future development of the forklift industry and playing a more important role in promoting the efficient and green development of logistics and industrial production.
