Definitions
- the invention relates to a battery, in particular secondary battery, with a plurality of arranged in a frame or housing battery cells, wherein at least two adjacent battery cells by a - preferably intumescent - protective material from a predetermined temperature are thermally insulated. Furthermore, the invention relates to a method for deactivating a battery having a plurality of arranged in a frame or housing battery cells in case of damage, wherein at least two adjacent battery cells are thermally insulated by a - preferably intumeszentes - protective material from a predetermined temperature.
- Rechargeable batteries having a plurality of battery cells are used, for example, for driving motor vehicles. Since a voltage is applied to the battery in the unused state, in the event of a fault, dangers to man and the environment may arise, since uncontrolled energy, for example in the form of electricity, voltage or heat, can be released.
- the short-circuit current can by the internal resistance heat up the closer environment of the damaged area so far that the surrounding areas are also affected.
- adjacent battery cells of a faulty so-called infected battery cell can be heated in such a way that the so-called thermal runaway occurs.
- This thermal runaway is an unstable chemical process that destroys the infected cells.
- the stored energy in the battery is released in a short time.
- the infected battery cell can heat up to temperatures of up to 800 ° C.
- this chain reaction is favored by the oxygen content of the air as soon as electrolyte leaking through the cell valve reacts with oxygen.
- the battery cell is affected by dendrite to an internal short circuit that causes the boiling point to be exceeded.
- the molten substances are very reactive and highly flammable. Therefore, it can quickly come to an explosive thermal runaway.
- the object of the invention is to avoid these disadvantages and to avoid infection of adjacent battery cells in a thermal run through a defective battery cell.
- this is achieved in that at least two battery cells arranged juxtaposed in at least one cell stack in a stacking direction are arranged displaceably in a housing or frame in the stacking direction, and a protective material is arranged at least between two adjacent battery cells in the stacking direction, so that from a predetermined Temperature two adjacent battery cells through the protective material, away from one another in the stacking direction, are displaceable in a fire protection position.
- a relative movement of two battery cells to each other along the stacking direction in a cell stack understood.
- at least one point of the one battery cell moves relatively in the stacking direction to a point of the other battery cell.
- all points of the one battery cell move relatively in the stacking direction to all points of the other battery cell.
- a particularly good thermal separation of the two battery cells from one another is achieved when the one battery cell moves relative to the other battery cell in the stacking direction such that the two battery cells remain substantially parallel to one another.
- each battery cell or at least one battery cell in a cell stack completely or at least partially surrounded by a intumescent protective material having fire protection jacket, wherein preferably the fire wall is arranged as fire protection layer, fire protection tape or fire wall on or on at least one battery cell.
- the intumescent protective material is arranged only in a partial area between two adjacent secondary batteries.
- the intumescent protective material is introduced by a blowing agent from the predetermined temperature between at least two battery cells, wherein preferably the intumescent protective material is part of a fire protection or extinguishing agent.
- the anode and cathode of adjacent battery cells are usually electrically connected by cell contacts and thus have a high thermal conductivity, it is advantageous if, in the fire protection position, the two adjacent battery cells are separated both thermally and electrically. This ensures that the thermal bridge between two adjacent battery cells is completely separated and thermal runaway is prevented.
- the battery has at least one release means for electrical separation of at least one electrical connection between two adjacent battery cells, wherein preferably a predetermined breaking point in the electrical connection between the two adjacent battery cells is arranged. About this breaking point in the electrical connection between two adjacent battery cells, the thermal bridge formed by the cell contacts of the battery cells can be destroyed.
- At least one release agent is formed by, for example, an aluminothermic mixture, the electrical separation in this case taking place by means of a thermite reaction on at least one electrical connection between two adjacent battery cells.
- a fire powder formed by an aluminothermic mixture is applied as a thin coating strip to a cell contact. The firing powder burns from a predetermined ignition temperature on the cell contact and thus interrupts the thermal and electrical connection of the cell contacts.
- At least one release agent is formed by an electrically conductive adhesive or solder between the cell contacts of two adjacent battery cells, which is designed to intercommunicate the electrical connection between the cell contacts from a defined temperature or a defined tensile or shear stress to interrupt the cell contacts of adjacent battery cells. Upon displacement of two adjacent battery cells thus the connection between the adhesive or solder and the cell contacts, or the adhesive or solder itself, mechanically broken.
- a bimetal is applied to the anode or cathode of the cell contact, which bends the cell contact above a certain activation temperature and thus interrupts the electrical connection.
- At least one separating means is formed by a mechanical separating device which, when at least one battery cell is displaced into the fire protection position, cuts through at least one electrode of the battery cell.
- the mechanical separating device is in a preferred embodiment firmly connected to the housing or the frame of the battery and may be formed by a cutting tool having at least one cutting edge whose cutting direction is formed substantially parallel to the stacking direction.
- the intumescent protective material in combination with at least one blade attached to the cell frame or housing, the transmission of the heat from the defective battery cell to the adjacent battery cell via the cell contacts can be effectively prevented.
- the electrical conductivity of the cell contacts is not affected because the cutting edge is arranged at a defined minimum distance from the cell contacts and thus does not normally come into contact with the cell contacts. Since no external trigger mechanism is required for the separator, thus, such a source of error is excluded.
- the invention is particularly advantageous for batteries in which the battery cells are formed by flat cells or pouch cells, the use of course is not limited to these battery cell types.
- the fire protection jacket may be formed by a tape, a mat, or an applied layer of protective material.
- At least part of the fire protection jacket is located between two battery cells designed as flat cells or pouch cells.
- An intumescent material is a material which, at a certain temperature, increases its volume by applying a specific inflation pressure and, for example, swells or swells, such as expanded graphite. Intumescent material is fire retardant and able to absorb at least some of the thermal energy that occurs in its environment.
- the predetermined temperature is preferably above the operating temperature of that battery cell in the battery, which has the highest operating temperature. Conveniently, the predetermined temperature is below a temperature by which one of the adjacent battery cells in the battery could be damaged.
- the protective material at the predetermined temperature is adapted to reduce the spread of heat energy, preferably to prevent or possibly also to absorb heat.
- the protective material is designed such that it can be adapted to the shape of the battery cell well and so the battery cell can be ideally exploited.
- the protective material is arranged in the cell stack in such a way that it does not disturb the regular operation and becomes active and preventive only in the event of a fault.

- This intumescent protective material 6 may be, for example, part of a fire protection jacket, which the battery cells 5 partially or completely surrounds.
- the fire protection casing is designed, for example, as a fire protection layer, fire protection strip or fire protection mat and arranged at least between two adjacent battery cells 5.
- the intumescent protective material 6 can also be injected or blown in between the neighboring battery cells 5 only in the event of damage by means of a propellant, wherein the propellant is activated at a defined temperature.
- the infected battery cell 5a and the adjacent harmless battery cells 5b within the cell stack 3 are relatively displaced away from each other, so that a distance a is formed between the harmless battery cells 5b and the infected battery cell 5a, as shown in FIGS. 1 and 2.
- the displacement effect is realized by the increase in volume starting from a certain temperature of the intumescent protective material 6 between the infected battery cell 5a and the adjacent harmless battery cell 5b.
- the increase in volume is effected in this case by the foaming of the intumescent protective material 6 above a predetermined temperature (for example ⁇ 200 ° C.).
- the infected battery cell 5a of harmless battery cells 5b not only thermally, but are also electrically separated, for example, the cell contacts 7 may be designed with predetermined breaking points 8, which break at a relative displacement movement of adjacent battery cells 5 and share in Maiseile 7a and 7b, whereby the electrical connection is interrupted.
