- Lithium-Ion batteries typically a voltage lower than 120V.
- battery means a set of individual modules each comprising power elements arranged in series and/or parallel in order to achieve the desired electrical voltage and electrical capacity.

- each stack of cells comprises at each of its ends a layer of end foam, such that the compression plates are in contact with said layers of end foam of the stacks.
- the battery comprises at least one heat sink disposed on a first external surface of at least one cell of each stack and/or comprises at least one intermediate foam layer disposed on a second external surface of at least one cell of each stack, the second external surface being opposite the first.
- the heat sink comprises at least one layer of graphite and at least one layer of glue.
- the heat drain is folded under the cell with which it is in contact, so as to constitute a contact surface of the drain with the base.
- Such a configuration makes it possible to increase thermal transfers between the base and the cells.
- the battery includes a layer of glue covering the contact surface of the drain with the base.
- the fixing means comprise first and second fixing elements, said first elements being fixed on the base and intended to pass through holes provided on a base of each compression plate, and said second fixing elements cooperating with the first fixing elements to fix the compression plates to the base.
- the first fixing elements fixed to the base comprise at least one stud.
- said stud passes through a hole provided at the base of the compression plate, and oriented in the direction of lateral movement of the compression plate.
- the second fastening elements comprise at least one nut.

- the second fastening elements 19 may be nuts.
- the base 3 is provided with adjustment means 21 capable of imposing a lateral displacement D on at least one compression plate 8.
- the lateral displacement is imposed here by a rotation R of a cam 22 whose profile is in contact with the plate 8 and which presses on the latter.

- At least one stack 7 of electric cells 6 is placed against the first plate 8.
- Each stack 7 is preferably installed at a second predetermined dimension, different from the first, so that the edge intended to be in contact with the base 3 is further from the center of the stack than the edge of the base 20 also intended to be in contact with the base 3. This difference between the first dimension and the second dimension is called "negative clearance".
- a flexible seal can be provided under each cell 6, also creating a negative clearance.
- a second compression plate 8 opposite the first and arranged in contact with the stacks 7 of cells 6 is then put in place (step 28). The second compression plate is put in place at the same first dimension as the first compression plate 8.
- the method continues with a step 29 of pressurizing the two compression plates 8 against the stacks of cells, using pressurizing means.
- the pressurizing means may in particular be hydraulic cylinders, preferably controllable in movement.
- the two compression walls 8 are gradually brought closer together by controlling the pressurization means. Control is preferably carried out by movement to ensure perfect control of the relative position of the compression plates 8.
- the method continues with a step 31 of fixing the compression plates to the base 3, followed by a step 32 of installing the tie rods 12.
- the step 32 of installing the tie rods 12 can be carried out before the step 31 of fixing the plates 8 to the base 3.
- the method may include an optional step of placing a layer of glue on the contact surfaces 16b of the heat drains 16 with the base 3.
- the layer of glue and the additional pressure between the stacks 7 and the base 3 generated by the negative clearance described above contribute to maintaining contact between the heat drains 16 and the base 3.
- the process ends with tensioning the tie rods 12 (step 33).
- the tensioning of the tie rods can be carried out by removing or by deactivating the pressurizing means used during the previous pressurizing and rimpedement steps.
- the tension of the tie rods 12 could be increased, for example by means of active anchors.
- the tension forces of the tie rods 12 are balanced by the compression forces acting on the compression plates 8.
