[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 2 , Figure 4 , Figure 5The present invention provides an embodiment of a lead-acid battery grid structure with improved current collection, comprising a battery container 1, to which a middle cover 2 is fixedly connected on the outside to protect the internal structure of the battery and prevent electrolyte leakage. A cover plate 3 is further fixedly connected on the outside of the middle cover 2. The cover plate 3 is typically made of a corrosion-resistant material to ensure the safety and sealing of the battery during long-term use. Multiple electrode groups are fixedly connected on the inside of the battery container 1, and multiple insulating separators 4 are fixedly connected on the outside of the electrode groups. These not only serve to isolate the positive and negative electrode plates 6 but also help maintain the structural stability of the battery. Each insulating separator 4 is provided with multiple holes 5, which allow the electrolyte to flow freely, thereby promoting the electrochemical reaction. A plate 6, one of the core components of the battery, is fixedly connected on the outside of the insulating separator 4. The plate 6 is responsible for storing and releasing electrical energy. A grid frame 7 is further fixedly connected on the outside of the plate 6. The frame is typically made of a metal material with good electrical conductivity, such as lead or its alloy, to provide a good current conduction path. The outside of the grid frame 7 is fixedly connected with a tab 8, which is a key part for connecting the battery to the external circuit and needs to have excellent conductivity and durability.

[0033] In order to improve the stability of the entire grid structure, a support assembly is also fixedly connected to the outside of the grid frame 7. This support assembly includes transverse ribs 9, which span between the grid frames 7 and provide lateral support for the entire structure. The transverse ribs 9 are fixedly connected to the outside with multiple vertical ribs 10. These vertical ribs 10 and the transverse ribs 9 form a grid structure, further enhancing the overall strength and stability of the grid. At the same time, this grid structure also contributes to the uniform distribution of current and the rapid dissipation of heat. The support assembly is fixedly connected to the outside with multiple fixed blocks 11. These fixed blocks 11 are used to firmly fix the support assembly in the battery compartment 1. The fixed blocks 11 are provided with flow guide holes 12 inside. The flow guide holes 12 allow the electrolyte to flow smoothly inside the battery, ensuring the full progress of the electrochemical reaction. The lead-acid battery grid structure with improved current collection has achieved an improvement in current conduction efficiency and a reduction in resistance loss through optimized design and material selection, thereby extending the battery life and improving overall performance.

[0034] Reference Figure 1 , Figure 3, the inside of the battery container 1 is fixedly connected with a plurality of springs 13, and the springs 13 are usually made of corrosion-resistant and highly elastic metal materials, such as stainless steel or alloy steel. The other end of the spring 13 is fixedly connected with a protective plate 14, which is used to prevent the components inside the battery from being damaged when subjected to external impact. The protective plate 14 is usually made of a strong and lightweight material, such as plastic or a composite material. The other end of the spring 13 is fixedly connected to the outside of the battery container 1, and a pole group partition 15 is also fixed inside the battery container 1 to isolate different parts inside the battery to ensure the orderly flow of current. The pole group partition 15 is usually made of an insulating material, such as plastic or rubber, to prevent current short circuit. In addition, the inside of the battery container 1 is also fixedly connected with a plurality of busbars 16, which are used to bring the current inside the battery together for efficient transmission. The busbar 16 is usually made of a metal material with good conductive properties, such as copper or aluminum. The busbar 16 is externally fixedly connected with a bridge 17, which is used to connect different busbars 16 to achieve current bridging and distribution. The bridge 17 is usually made of the same material as the busbar 16 to ensure smooth current transmission.

[0035] The other end of the busbar 16 is fixedly connected to a stud 18. Stud 18 is a key component that connects the battery to the external circuit and requires excellent conductivity and durability. Stud 18 is typically made of conductive materials such as copper or aluminum and undergoes special treatment to improve its corrosion and oxidation resistance. Multiple safety valves 19 are fixedly connected to the outside of the middle cover 2. These safety valves 19 are designed to automatically open when the internal pressure of the battery is too high, releasing pressure and preventing the battery from exploding. Safety valves 19 are typically made of high-temperature and high-pressure resistant materials, such as metal or ceramic. Multiple ports 20 are also fixedly connected to the outside of the middle cover 2. These ports 20 are used to connect the battery to external devices, such as chargers and dischargers. Ports 20 are typically made of conductive materials and equipped with sealing rings or gaskets to ensure a tight and secure connection. A rubber plate 21 is fixedly connected to the outside of the port 20 to protect it from external environmental influences, such as moisture and dust. Rubber plate 21 is typically made of a soft and durable material, such as rubber or silicone. Finally, the outer end of the rubber plate 21 is fixedly connected to the outer end of the cover plate 3, and the other end of the safety valve 19 is also fixedly connected to the outer end of the cover plate 3. This design can ensure the overall sealing and safety of the battery, preventing electrolyte leakage and external impurities from entering the battery.

The outside of the grid frame 7 is also fixedly connected to a support assembly, which includes transverse ribs 9, which span between the grid frames 7 to provide lateral support for the entire structure. The outside of the transverse ribs 9 is fixedly connected with a plurality of vertical ribs 10, which further enhances the overall strength and stability of the grid. At the same time, this grid structure also contributes to the uniform distribution of current and the rapid dissipation of heat. The outside of the support assembly is fixedly connected with a plurality of fixed blocks 11, and the inside of the fixed block 11 is provided with a guide hole 12. The guide hole 12 allows the electrolyte to flow smoothly inside the battery to ensure the full progress of the electrochemical reaction.

A pole group partition 15 is also fixed. A plurality of busbars 16 are also fixedly connected to the inside of the battery container 1. These busbars 16 are used to bring the current inside the battery together for effective transmission. The bridge 17 is used to connect different busbars 16 to achieve current bridging and distribution. The bridge 17 is usually made of the same material as the busbar 16 to ensure smooth current transmission. The column head 18 is a key part connecting the battery with the external circuit and needs to have excellent conductivity and durability. The outside of the middle cover 2 is fixedly connected to a plurality of safety valves 19. These safety valves 19 are used to automatically open when the internal pressure of the battery is too high to release pressure and prevent the battery from exploding.
