In the grand layout of industrial logistics, forklift bears the heavy responsibility of material handling and is the key equipment to ensure the smooth operation of the production process. The forklift traction lead-acid battery, as the core power unit of forklift, has left a deep mark in the field of industrial power with its unique performance characteristics and wide applicability. In-depth study of forklift traction lead-acid battery, not only can understand its key value in the current industrial scene, but also grasp its future development trend.

Ⅰ. Structure and principle: Chemical reactions give rise to power

The internal structure of the lead-acid battery pulled by the forklift is delicate and complex, and the various components work together to convert chemical energy into electricity. The battery is mainly composed of a positive plate, a negative plate, an electrolyte, a separator and a shell. The positive plate is usually coated with lead dioxide, which is hard; The negative plate is made of spongy lead as the active material, and the texture is relatively soft. The plate is housed in an enclosure made of corrosion-resistant material that protects and seals internal components from damage and electrolyte leakage.

The separator is located between the positive and negative plates, and its existence is crucial, both to prevent direct contact between the positive and negative plates and short circuit, and has a porous structure, allowing ions in the electrolyte to pass freely, maintaining the continuous electrochemical reaction. The electrolyte is generally an aqueous solution of sulfuric acid, its density is usually maintained within a specific range, and is a key participant in electrochemical reactions.

The working principle is based on REDOX reaction. Upon discharge, the lead atoms on the negative plate lost electrons to lead ion (Pb² +.) which combined with the sulfate ion (SO₄²⁻) in the electrolyte to form Lead sulfate (PbSO₄) ₄ which precipitated onto the plate. The electrons flowed through an external circuit to the positive electrode, forming an electric current. At the positive plate, lead dioxide, after receiving electrons, reacts with the hydrogen ion (H +) and sulfate ions in sulfuric acid, also producing lead sulfate and water. The charging process is the reverse reaction of the discharge, under the action of the external power supply, the lead sulfate decomposing, the positive and negative plates are restored to lead dioxide and lead, the sulfuric acid concentration in the electrolyte is recovered, and the chemical energy can be re-stored.

Ⅱ.Performance advantage: meet the stringent needs of industry

(1) Excellent high current discharge capability

In the actual operation, the forklift needs to output powerful power instantaneously when starting, accelerating and carrying heavy objects, which puts forward extremely high requirements for the high current discharge performance of the battery. Forklift traction lead-acid batteries are excellent in this respect, and can provide high rate current in a short time to meet the instantaneous high-power needs of forklifts. For example, when handling a pallet full of goods in a warehouse, the lead-acid battery can quickly release electrical energy to help the forklift start easily and accelerate smoothly, efficiently complete the handling task, and ensure the smooth flow of logistics operations.

(2) Significant cost-effectiveness

Compared with some new battery technologies, the raw material cost of lead-acid batteries is relatively low. As the main raw material, lead has abundant reserves and relatively stable price, and its production process has been quite mature after long-term development, and the scale effect is significant, making the overall manufacturing cost of forklift traction lead-acid batteries controllable. For small and medium-sized enterprises with limited budgets, the financial pressure on the purchase of lead-acid battery forklift trucks is small, and its subsequent maintenance costs are relatively low, and the technical threshold for routine maintenance operations such as replenishment of electrolyte and inspection of plate conditions is not high, and enterprises can maintain the normal operation of forklifts at a lower cost.

(3) Broad environmental adaptability

The industrial environment is complex and diverse, and the temperature, humidity and other conditions vary greatly. The lead-acid battery pulled by forklift can adapt to a wide range of environmental conditions to a certain extent. In high temperature environments, such as some steel mills and casting workshops, although the battery performance will be reduced, the basic working capacity can still be maintained through appropriate ventilation and heat dissipation measures. In low-temperature environments, such as cold storage operation scenarios, some lead-acid batteries can work normally within a certain low temperature range by optimizing the electrolyte formula, adding special additives to reduce the freezing point of the electrolyte, and cooperating with insulation measures, showing good environmental adaptability.

Ⅲ. Application panorama: Multi-point flowering in the industrial field

In modern warehouse logistics center, forklift operation is frequent and the task is heavy. Forklift with its excellent performance, forklift has become the main equipment for cargo handling, stacking and handling. In the narrow shelf channel, the lead acid battery forklift shuttles flexibly, accurately placing the goods in the designated position. Its stable power output ensures the reliability of long-term continuous operation, can meet the high-intensity and high-efficiency operation needs of warehousing logistics, ensure the rapid flow of goods, and improve the efficiency of warehousing operations.

(2) Efficient support for the manufacturing industry

In the manufacturing factory, from the handling of raw materials to the transportation of semi-finished products and finished products, forklifts are everywhere. With its cost advantages and stable performance, lead-acid battery forklifts provide an efficient material handling solution for manufacturing production processes. In the electronic manufacturing workshop, the environmental cleanliness requirements are high, and there is no exhaust emission during the operation of lead-acid battery forklift trucks, which will not pollute the production environment; In automotive manufacturing plants, forklifts need to carry large parts, and the powerful power output of lead-acid batteries can be easily handled to ensure that production links are closely connected and promote the efficient operation of manufacturing.

(3) Port pier heavy duty

The port terminal is a logistics hub with huge cargo throughput, where forklift trucks bear the heavy responsibility of handling large containers and loading and unloading various kinds of goods. Forklift traction lead-acid battery Forklift has become an important handling equipment in port terminals due to its high power output and rugged characteristics. In harsh outdoor working environments, such as high temperature, high humidity and seaside docks with salt spray corrosion, lead-acid battery forklifts can effectively resist environmental erosion and operate stably through special protection designs. Its powerful power is enough to drag heavy containers to meet the needs of high-intensity and heavy-duty operations at port terminals, and ensure the efficient handling of cargo.

Ⅳ. Challenges and Breakthroughs: The road to innovation
