[0020] Hereinafter, the embodiments of the present invention will be described in detail, and examples of the embodiments are shown in the drawings, and the same or similar reference numerals throughout indicate the same or similar parts or parts having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are for interpreting the present invention, but should not be understood as limiting the present invention.

[0021] As shown in FIGS. 1 and 5, the electronic device 100 includes a case 10, a functional assembly 20, and a battery 30.

[0022] The case 10 is formed with an accommodating space for accommodating the functional assembly 20 and the battery 30. In a specific implementation, the case 10 usually includes a container and a cover plate, the accommodating space is formed in the housing, and the cover plate closes the open side of the container, which can be set according to a specific structure of the electronic device 100, so the specific embodiment is not limited in detail.

[0023] The functional assembly 20 includes a functional component 210, is attached inside the case 10, and occupies a part of the accommodation space.

[0024] The battery 30 includes a main body portion 310 , a protruding portion 320 and a recessed portion 330 .

[0025] Both the protrusion 320 and the recess 330 are formed in the main body portion 310. The recess 330 is not a solid structure, but an escape space formed in a portion of the main body portion 310 where no solid material is provided.

[0026] The main body portion 310 and the protrusion portion 320 occupy at least a part of the surplus space 220 of the accommodation space. The recess 330 is provided corresponding to the functional component 210 and allows the functional component 210 to escape. The correspondence of the recess 330 to the functional component includes two points, that is, in an assembled state of the electronic device 100, the position of the recess 330 corresponds to the functional component 210, and the spatial shape of the recess 330 corresponds to the functional component 210, so that the space provided by the recess 330 is occupied by the corresponding functional component 210.

[0027] In a specific implementation, the electronic device 100 may be a portable device such as a notebook computer, a tablet computer, or other smart electronic products, such as a mobile phone, a wearable device, etc. In Figs. 1 to 5 and the following description of the present application, the electronic device 100 is described as a notebook computer.

[0028] When the electronic device 100 is a notebook computer, the case 10 is a housing for the host part of the notebook computer, and the functional parts 210 included in the functional assembly 20 mainly include a motherboard, a CPU, a hard disk, a memory, a video card, a sound card, a radiator, etc. The battery 30 is a power supply battery for the notebook computer.

[0029] After the CPU, hard disk, memory, video card, sound card and radiator are attached to one side of the motherboard, the side facing the internal accommodating space of the housing occupies part of the accommodating space. In addition, the specifications of the functional components are diverse, and after assembly, the shape of the remaining accommodating space is irregular and not flat due to the unevenness of the functional components and the arrangement spacing of the functional components.

[0030] Accordingly, most of the main body 310 of the battery is provided as a regular structure and can occupy most of the continuous space in the excess storage space, and in order to improve the utilization rate of the storage space, the main body 310 of the battery is further provided with the protrusion 320 and a recess 330.

[0031] The protrusion 320 is provided to fit the irregular shape of the remaining space 220 after the functional component 210 is occupied, and occupies at least a part of the remaining space of the receiving space. In a specific implementation, the protrusion 320 can fit mainly to the area of ​​the remaining space where the functional component 210 is not provided, or to the area of ​​the remaining space where the functional component 210 is installed and the protruding height of the corresponding functional component 210 is smaller than a predetermined value.

[0032] In a specific implementation, the main body 310 is formed with a plurality of protrusions 320, and at least two of the plurality of protrusions 320 have different heights. Specifically, in an implementation, the plurality of functional components 210 included in the electronic device 100 usually have different size specifications, and the spaces occupied by the plurality of functional components 210 are accordingly different, and the surplus space 220 between the functional components 210 is also usually irregular in shape. By setting at least some of the protrusions 320 to different heights, the surplus space 220 can be fully utilized. As can be understood, the outer shapes of the plurality of protrusions 320 also match the shapes of the corresponding surplus spaces 220 between the functional components 210.

[0033] Accordingly, the escape portion 330 may be provided in a region where the protruding height of the functional component 210 is greater than a predetermined value, and allows the functional component 210 to escape, and the spatial shape of the escape portion 330 corresponds to the functional component 210, so that the space provided by the escape portion 330 is occupied by the corresponding functional component 210.

[0034] In this way, the protrusion 320 occupies part of the excess space not occupied by the functional component 210, and the relief portion 330 provides relief for part of the storage area for functional components with a large protruding height, thereby not only preventing the battery 30 from interfering with the functional component 210 but also improving the utilization rate of the storage space.

[0035] In the above-mentioned electronic device 100, the battery 30 includes a main body 310, and a protrusion 320 and a recess 330 formed on the main body 310, the main body 310 and the protrusion 320 occupy at least a portion of the excess space of the storage space, the recess 330 is provided corresponding to the functional component 210, and by allowing the functional component 210 to escape, the battery 30 and the functional assembly 20 of the electronic device 100 each occupy a portion of the storage space formed by the case 10, and in terms of space, the battery 30 and the functional assembly 20 can escape and replenish each other, making full use of the storage space, which is helpful in making the electronic device 100 thinner.

[0036] In one embodiment, the recess 330 includes a groove 3310 disposed toward the functional component 210. When the battery 30 is assembled to one side of the functional component 210, the groove 3310 accommodates at least a portion of the volume of the corresponding functional component 210.

[0037] When the overall size of the case 10 is set, for the position where the functional part 210 is provided, the size of the unoccupied part of the case 10 in the protruding direction of the functional part 210 is determined based on the protruding size of the functional part 210 and the size of the case, and if the size of the unoccupied part is suitable for providing the battery 30 in consideration of the difficulty of the processing process of the battery 30, a groove 3310 can be provided at the position, thus not only allowing the functional part 210 to escape, but also reserving a part for accommodating the battery 30 at the corresponding position. As can be understood, if the size of the unoccupied part is too small, the part for accommodating the battery 30 at the corresponding position is not reserved, for example, the escape part may include a notch 3320 provided corresponding to the functional part 210, and if the size of the unoccupied part is too small, the notch 3320 is formed at the corresponding position of the battery 30.

[0038] In a specific implementation, the notch 3320 is usually located at the edge of the main body 310, which can avoid forming a notch in the middle of the battery 30 and reduce the difficulty of the manufacturing process of the battery 30.

[0039] The functional assembly 20 typically includes a plurality of functional components 210. Accordingly, the recess 330 includes a plurality of grooves 3310 provided corresponding to the plurality of functional components 210.

[0040] In one embodiment, the depths of the grooves 3310 may be the same, and in this case, the depth of the groove 3310 must be adapted to the functional component 210 with the highest protruding height in the functional assembly 210. In other words, when the grooves 3310 are set to the same depth, the depth of the groove 3310 must be set to accommodate the protruding portion of the functional component 210 with the highest protruding height, and only in this way can it be ensured that the protruding portions of all the functional components 210 can be accommodated in the corresponding grooves 3310. By setting the grooves 3310 to the same depth, the difficulty of designing and processing the battery 30 can be reduced.

[0041] The depths of the plurality of grooves 3310 are also different from each other, or at least some of the grooves 3310 are different in depth, and the depths of the plurality of grooves 3310 are different from each other. 210 In this way, the remaining space 220 after the functional components 210 of the accommodation space are occupied can be fully utilized.

[0042] The contour of the groove 3310 is similar to the outer contour of the corresponding functional component 210, so that the groove 3310 can easily accommodate the protruding portion of the functional component 210 and can fully utilize the excess space 220.

[0043] In a preferred embodiment, the main body 310 includes a first surface 3110 and a second surface 3120 located opposite each other.

[0044] The first surface 3110 faces the functional component 210, and the protrusion 320 and the recess 330 are formed on the first surface 3110.

[0045] The second surface 3120 is substantially planar. In this manner, the main body 310 may be adapted to the functional component 210 by the protrusion 320 and the recess 330 on one side, and the second surface 3120 on the other side may be provided as a flat surface toward the external case 10 for final assembly of the electronic device 100.

[0046] In a specific implementation, the battery 30 may be a solid-state battery or a semi-solid-state battery.

[0047] After the protrusions 320 and the recesses 330 are provided in the battery 30 of the present application, the external shape of the battery 30 has characteristics of being irregular and having a thin local thickness.

[0048] When manufacturing the above battery 30, the size and shape of the plates required for each position must be designed based on the corresponding external shape of the battery.

[0049] For plates that need to be designed in irregular sizes, the positive and negative plates after pressing are divided into multiple positive and negative plate units with specific shapes by a customized positive and negative die cutter, and then the positive and negative plates are assembled and placed in specific positions through a lamination process, while the positive and negative tabs are reserved in advance when the plates are die cut in the previous stage, simplifying the material input and design of the tabs. Since plates at different positions are located inside an integrated cell, the layout of the tabs inside the battery needs to be specially designed, and since plates at different positions need to work simultaneously, plates with different properties need to be stacked to meet the consistency requirements.

[0050] Although the ultra-thin part of the battery 30 is manufactured with thick electrodes with a small number of windings, when the number of windings of the battery is reduced, the surface density of the positive and negative plates of the cell can be gradually increased, and the increase in surface density places higher and higher requirements on the process, materials, etc. of the battery. Therefore, in order to gradually increase the energy density by reducing the number of windings, it is necessary to further optimize the process, improve the positive and negative electrode materials and electrolyte, and use positive and negative electrode materials with better kinetics to realize the rapid transition inside the particles of lithium ions. However, if it is necessary to manufacture an ultra-thin battery with a small size and high energy density, it is difficult to meet the requirements with conventional commercial batteries. Compared with current commercial batteries, solid-state batteries have the characteristics of high safety and high energy density, adjustable scale, and high design flexibility, and have attracted wide attention. Solid-state batteries can be designed according to specific demands, and can be designed into thin-film batteries with a thickness of only a few microns, or can be manufactured into macro-type batteries. Solid-state electrolytes can be divided into gel electrolytes, semi-solid electrolytes, quasi-solid electrolytes, and all-solid electrolytes according to the state of the solid electrolyte. Because solid electrolytes are non-flammable, non-corrosive, non-volatile, and have no leakage issues, solid-state batteries have inherent safety and longer service life.

[0051] In a semi-solid lithium battery, one electrode does not contain a liquid electrolyte, but the other electrode does. Compared with conventional lithium-ion batteries, therefore, a unique manufacturing process can be used to manufacture thick electrodes, simplifying the structural design and reducing the proportion of current collectors and separators when the same positive and negative electrode materials are used, thereby improving the energy density of the battery, and using thick electrodes allows the battery to be made ultra-thin.

[0052] After the design of the plates of different positions and different sizes is completed, the assembly of the plates of different sizes and different positions is completed through a lamination process, and the battery is stacked from bottom to top until it reaches the corresponding position of the tensile case, and the ultra-thin and irregular-shaped battery 30 is sealed together.
