Battery core C is packed into pack case P and is packaged later；One side glue is corresponded to from the external of pack case P to the battery core C for completing encapsulation
The position of material 1 is heated and/or is pressurizeed, so that 12 overflow of glue of single side glue material 1, thus form the glue 12 of Figure 17 to Figure 24
Various states.Battery core C and pack case P are fixed together as a result,.Wherein, before battery core C is packed into pack case P, visually
It is specific to need, battery core C is carried out avoiding scattering using other fixation device (such as adhesive tape) fixation.
As a result, in the secondary cell according to the application third aspect, the glue 12 of single side glue material 1 is by through-hole 111, from logical
The side in hole 111 overflows to the other side, to form the glue outside 111 periphery of through-hole, ensure that between battery core C and substrate 11 with
And all there is glue between pack case P and substrate 11, thus improve pack case resistance to deformation and resist corrugated ability, at the same time,
Glue outside 111 periphery of through-hole also increases the contact area between single side glue material 1 and pack case P, improves the anti-drop of battery core C
Performance.Specifically, in Fig. 9 into Figure 16, second part glue 122 is the glue outside 111 periphery of through-hole；And in Figure 17 to Figure 24

123 fillings) when, it is very easy to fill up through-hole 111.There are the inner walls of each through-hole 111 into Figure 19 by Figure 10 to Figure 11 and Figure 18
At least part be spaced apart with Part III glue 123.By the design of glue 12 and substrate 11 on material, make 12 mobility of glue
It is very good, but the compatibility (i.e. the compatibility of glue 12 and substrate 11) of the hole wall of the through-hole 111 of glue 12 and substrate 11 is deteriorated, and makes glue
12 can not contact preferentially with the hole wall of through-hole 111 and (be bonded) at excessive glue (i.e. Part III glue 121 is filled).
Wherein, the mobility of glue 12 can be realized by modulation process parameter, for example pass through control temperature, pressure and time
The mobility of all controllable glue 12.The mobility of glue can be effectively improved by properly increasing temperature, increase pressure and extension time.
As shown in Fig. 8 to Figure 24, glue 12 further include: Part IV glue 124, outside at least partly periphery S of substrate 11
Side.Battery core C and pack case P are more clamped securely to improve the anti-dropping capability of secondary cell together simultaneously by Part IV glue 124
