According to the design requirements and battery performance battery power apparatus size or quality requirements , the battery structure is designed to achieve a reasonable and effective materials and reduce the battery internal resistance and to vote for the battery ( group) structure,dell laptop battery single cell structural components , sealing structure Design aspects .
(1 ) battery ( group) structural design of major structural design , including single cells and single cells of connection between
Type design.
Single cell structure design to achieve single cells feed and feeding an effective way and reduce the internal resistance of individual cells as the main objective of the battery within the cavity Dell RC107 Battery,Dell Latitude D620 Battery, Dell 312-0386 Battery, in the effective conduct of different components of a reasonable size distribution and spatial arrangement of the components to ensure The feed is reasonable and effective feeding .
Single connection between the design of the battery main battery size to achieve the combination of electrical appliances to meet the requirements provided by the volume of space , and to minimize the resistance of the circuit connection . Connections between individual cells generally divided into two kinds: internal connections (such as lead-acid battery connection through the partition welding ) and the outer connection ( such as lead-acid battery connections linking method > , between the battery pack and battery The connections are all outside connections. whether within or outside the connection link , should be considered in the peak current or high current battery discharge in case of fever, and even fuse problem .DELL M1710 battery
(2 ) single cells structural design includes the positive and negative electrode structure and arrangement of design and membrane structural design, the amount of electrolyte solution design,Dell 312-0386 Battery, the battery shell design, sealing structure parts design.
The purpose of electrode structure design is to ensure reasonable and effective feeding amount of electrode material to improve the utilization of active materials and to reduce the electrode resistance and so on . Generally include plate dimensions (length , thickness, height and quality to determine , plate porosity and pore structure determination of active material and conductive to determine the relationship between the collector and so on . In the electrode structure design, the collector Structural design is also an important part of the structure can collector electrode resistance minimum , and around the electrode potential and current uniform distribution, so as to achieve the best effect of the energy output of the design of the electrode structure , usually electrode thickness , porosity , Mode of electrode formation process is the focus of the design .Lenovo IdeaPad Y650 Battery
Between anode and cathode arrangement is designed to : to achieve positive and negative electrodes are on the area between the determination to ensure the poles on the current and potential uniform distribution ; reasonable determination of distance between electrodes to ensure that the battery needed to accommodate between two poles The electrolyte and separator size requirements and with minimum resistance . Dell RC107 Battery,Dell Latitude D620 Battery, Dell 312-0386 Battery, Common arrangement of a bipolar plate electrode to form positive and negative polar groups in parallel staggered arrangement and belt plate in order to winding arc formed by the parallel arrangement of two forms. Lead-acid battery positive and negative electrodes are arranged , laminated flexible packaging lithium-ion battery arrangement of poles , laminated polarized laminated zinc-manganese batteries methods are very flat electrode to form positive and negative groups in parallel staggered arrangement ; Dell Latitude D620 Battery, cylindrical Lithium ion batteries , nickel hydrogen batteries, nickel- cadmium batteries are the polar arrangement of the winding belt plate to form a parallel arrangement of the arc . Only a single positive component zinc-manganese battery ( batteries ) and a negative component ( zinc cylinder , which is outside the arrangement of the inner negative cylinder concentric cylinders coaxial with the ring parallel manner , alkaline manganese dioxide batteries are the opposite .
It should be noted that the arrangement between the electrode , the electrode distance affects the consistency of a very different surface location of the current , potential distribution, may Daozhi the same plate ( or pole piece ) at different locations of the reaction efficiency ( activity of Wu Zhi Utilization different , that affect the uniformity of discharge electrode , thus affecting the effectiveness of its large current work , and even affect the uniformity of individual cells and battery cycle life.
