As shown in fig. 7, in one application, such as can use the much bigger battery cell element of quantity and form battery cell element mould Block or battery cell element stack 110, for providing electric power to motor 200 as battery, to be the confession of electric vehicle 300 Electricity.

Fig. 8 shows one embodiment of manufacturing method according to the invention.In reel stand 400, polymer foil is rolled up Cylinder 510 is unfolded, so that polymer foil 500 leaves reel stand 400.In stamping station 420, window 60 is stamped into foil by mold 520 In 500.At this point, if desired, can also be with punching press feed hole 305.As the replacement of stamping station, can be cut laser on foil 500 Cut or be otherwise applied as window and/or feed hole.At cutting station 430, such as will by rotor 530 and anvil block 532 Foil 500 is cut into individual polymer frame 20, and the frame 20 with window 60 leaves and reaches on conveyer 440.It can be with By in stack 528 can the partition 28 made of solid electrolyte material be placed on frame 20, it is stackable to be formed Component 98 can assemble stackable component 98 and other battery cell components, for example bipolar afflux part 22 in shell 40 Together, as described above.Alternatively, polymeric separator plates can be used, such as such as following as described in Figure 9.It can make With bar 99, and welding or other attach process described above can be used to complete battery module.

Fig. 9 shows another embodiment, wherein before cutting continuous band 198, adds at partition placement station 460 Add separator material, to form the continuous band 198 of the partition 28 of frame support.It can be as making in the embodiment in fig. 8 With solid-state partition, or the polymeric separator plates cut by cutter device 630 from reel 628 can be used.Such as it can pass through Partition 28 is attached to band 198 by welder 640.

Other than partition 28, bipolar afflux part 22 also can replace the separator material in the embodiment of Fig. 9, and for example Foil 500 is directly attached to by welding.In such a case, it is possible to add partition and anode and cathode later.

Also continuous band 198 can be used and carry out zigzag folding or the combination of zigzag and stacking.

Continuous band 198 can also be cut into lesser list by cutter device (cutter or laser cutter) 470 Member forms multiple individual units of stackable component 98.

By the way that partition-polymer frame unit is attached to shell, partition is no longer able to mobile or is slided in cell element. Therefore, this unit is more elastic, and can preferably be tolerated in use in automobile or any transporting equipment and send out when battery Raw vibration or impact, because the position of entire cell element heap is fixed inside cell element.

Equally, if using bipolar afflux part-polymer frame unit embodiment, bipolar afflux part is protected well Shield.

Shell 40 can also be saved, and frame 60 is simply welded together.

The stable battery of method and generation of the invention be particularly suitable for the electric vehicle significantly vibrated or Hybrid vehicle battery.
