Definitions
- the P value can be derived by multiplying the thickness (Pt) value of a single compression pad (400) by 4, which is the number (Pn) of the compression pads (400).
- the adhesive portion (600) can also be positioned between the compression pad (400) or the battery cell (110) located at the outermost side and the side portions (210, 220). In other words, as described above, an adhesive portion (600) may be provided on the inner surface of the side portion (210, 220). When the battery cell (110) and the compression pad (400) are considered as a single component, an adhesive portion (600) may be interposed between these components.
- the number (Dn) of the adhesive portions (600) may be calculated as a value that adds 1 to the sum of the number (Cn) of the battery cells (110) and the number (Pn) of the compression pads (400). For example, referring to the case of FIG.
- W is a distance value measured between the inner surfaces of the side portions (210, 220) of the module frame (200).
- the C corresponding to the total thickness of the battery cells (110) was calculated as the product of the thickness (Ct) of the center of the battery cells (110) and the number (Cn) of the battery cells (110).
- the compression pad (400) was confirmed to be compressed by 80% when inserted into the module frame (200) together with the battery cells (110), and thus the thickness (Pt) of the compression pad (400) in the compressed state was calculated as 20% of the thickness of the original compression pad (400) before being compressed.
- the above P which corresponds to the total thickness value of the compression pad in the compressed state, can be calculated as the product of the thickness (Pt) of the compression pad (400) in the compressed state and the number (Pn) of the compression pads (400).
- the above D corresponding to the total thickness value of the adhesive portions (600) can be calculated as the product of the thickness (Dt) of a single adhesive portion (600) and the number (Dn) of the adhesive portions (600).
- the adhesive portions (600) are located between adjacent battery cells (110), between the battery cells (110) and the compression pads (400), and on the outermost compression pads (400) or the outer surface of the battery cells (110).
- the number of adhesive portions (600) was calculated as the sum of the number (Cn) of the battery cells (110) and the number (Pn) of the compression pads (400) plus 1.
- Comparative Example 1 Comparative Example 2 Comparative Example 3 Distance between inner surfaces of side sections of module frame (W) [mm] 216.2 216.2 217.6 Total thickness of battery cells (C) [mm] 208.968 208.968 209.16 Total thickness of the compressed pad (P) [mm] 1.8 1.8 1.8 Total thickness of the bonding area (D) 1.4 1.5 1.5 Reserved Space Ratio per Battery Cell [%] 1.93 1.88 2.46 Remaining capacity at 800 cycles in battery cell unit [%] 80 80 80 Remaining capacity at 800 cycles in battery module unit [%] 61.2 61.2 64.2 Difference in capacity degradation between battery cells and battery modules [%] 18.8 18.8 15.8
- the free space ratio [%] per battery cell was calculated from the derived W, C, P, and D values of Comparative Examples 1 to 3, and it was calculated that Examples 1 to 3 had free space ratio values per battery cell of 1.93%, 1.88%, and 2.46%, respectively.
- the free space ratios per battery cell of Comparative Examples 1 to 3 are all less than 3%.
- Figure 6 is a perspective view showing a battery cell stack according to a comparative example of the present invention.
- the partially formed adhesive portion (60) causes an uneven surface pressure on the surface of the battery cell (110), and the gas generated by the uneven surface pressure exists on the surface of the battery cell, causing lithium plating, in which lithium is deposited on the surface of the battery cell (110).
- the adhesive portion (60) is formed only in the central portion of the battery cell (110)
- lithium is mainly deposited in the portions adjacent to both ends (114a, 114b) of the battery cell (110) from which the electrode leads (111, 112) protrude.
- the inventor of the present invention analyzed the relationship between the lithium precipitation rate in lithium plating and the remaining capacity rate of the battery cell, and confirmed that the lithium precipitation rate and the remaining capacity rate of the battery cell have a strong negative correlation. That is, as the lithium precipitation rate increases, the remaining capacity rate after 800 cycles decreases, and the uneven surface pressure of the battery cell (110) caused by the adhesive portion (60) adversely affects the life performance of the battery module (100). Accordingly, the inventor of the present invention proposed the adhesive portion (600) as a uniform pressure-applying structure for the surface of the battery cell (110). Hereinafter, the formation area of the adhesive portion (600) according to the present embodiment will be described with reference to FIGS. 3, 7, and 8.
- Fig. 7 is a perspective view showing a battery cell stack according to one embodiment of the present invention.
- Fig. 8 is a plan view showing an adhesive portion formed on one surface of a battery cell according to one embodiment of the present invention.
- the battery cells (110) are pouch-shaped battery cells in a sheet shape, and the battery cells (110) can be stacked in an upright shape so that one side of the battery cells (110) is parallel to the side portions (210, 220, see FIG. 2).
- the battery cells (110) can be stacked so that the one side thereof faces each other. That is, the one side of the battery cell (110) described below corresponds to a portion of the battery cell (110) that is parallel to the side portions (210, 220) of the module frame (200), and can face another battery cell (110), a compression pad (400), or the side portions (210, 220) of the module frame (200).
- the adhesive portion (600) may be attached to the surface of the battery cell (110) so as to cover the surface of the battery cell (110).
- the adhesive portion (600) may be attached to the surface of the battery cell (110) so as to cover an area of 90% or more and 100% or less of the surface area of the battery cell (110).
- the adhesive portion (600) may be attached to the surface of the battery cell (110) so as to cover an area of 90% or more and 101% or less of the surface area of the battery cell (110).
- the adhesive portion (600) according to the present embodiment can be attached so as to cover most of the above-mentioned one surface of the battery cell (110). Accordingly, a uniform pressure-applying structure for the above-mentioned one surface of the battery cell (110) can be implemented. Unlike the adhesive portion (60) that was attached only to a narrow area, the adhesive portion (600) according to the present embodiment can secure uniformity of the pressure applied to the surface of the battery cell (110), and accordingly, solve the problem of lithium plating occurring in the adjacent portions (114a, 114b) of the battery cell (110), thereby improving the life performance of the battery module (100).
- the battery module (100) according to the present embodiment may further include a thermally conductive resin layer (700) positioned between the battery cell laminate (120) and the lower surface (240) of the module frame (200).
- a thermally conductive resin layer (700) positioned between the battery cell laminate (120) and the lower surface (240) of the module frame (200).
- the thermally conductive resin layer (700) may be formed by applying a thermally conductive resin to the lower surface (240) and hardening the applied thermally conductive resin, or by injecting the thermally conductive resin through a through hole formed in the lower surface (240).
- a thermally conductive resin to the lower surface (240) and hardening the applied thermally conductive resin, or by injecting the thermally conductive resin through a through hole formed in the lower surface (240).
- the thermally conductive resin layer (700) may be formed by dividing it into two sections so as to correspond to the two sections of the battery cell stack (120) in which heat generation is severe.
- the thermally conductive resin may include a thermally conductive adhesive material, and specifically, may include at least one of a silicone material, a urethane material, and an acrylic material.
- the thermally conductive resin may be in a liquid state when applied or injected, or may be hardened after application or injection to fix one or more battery cells (110) forming the battery cell laminate (120). In addition, since it has excellent thermal conductivity, it can quickly transfer heat generated from the battery cells (110) to the lower side of the battery module.
- One or more battery modules according to the above-described embodiment can be mounted together with various control and protection systems such as a BMS (Battery Management System), a BDU (Battery Disconnect Unit), and a cooling system to form a battery pack.
- BMS Battery Management System
- BDU Battery Disconnect Unit
- cooling system to form a battery pack.
- the above battery module or battery pack can be applied to various devices. Specifically, it can be applied to means of transportation such as electric bicycles, electric cars, hybrids, or ESS (Energy Storage Systems), but is not limited thereto and can be applied to various devices that can use secondary batteries.
- means of transportation such as electric bicycles, electric cars, hybrids, or ESS (Energy Storage Systems)
