Definitions

  • This invention relates in general to batteries, and more specifically to batteries exposed to high temperatures.
  • FIG. 1 is a top view of a battery pack including heat deflective packaging in accordance with the present invention.
  • FIG. 2 is a top view of an electronic device in which the battery of FIG. 1 can be used in accordance with the present invention.
  • FIGs. 3 and 4 are side views of battery packs having packaging that includes heat deflective material in accordance with the present invention.
  • FIG. 5 is a perspective view of a battery cell having heat deflective packaging in accordance with the present invention.
  • FIG. 6 is a perspective view of a battery cell having a heat deflective label in accordance with the present invention.
  • FIG. 1 a top view of an energy storage device, such as a battery pack 100, a capacitor, or another electrochemical cell, is depicted.
  • the battery pack 100 includes at least one battery cell 105 around which packaging 110 is assembled.
  • electrical contacts for the battery pack 100 can be formed in a conventional manner, such as by extending tabs (not shown) from cell terminals through the packaging 110.
  • Energy storage devices such as the battery pack 100
  • lightweight, portable devices e.g., cellular telephones, radio communicators, and laptop computers.
  • Such electronic devices can be used in high temperature environments, for example, within closed automobiles, and can also include components, such as microprocessors and the battery pack 100 itself, that generate heat within the devices.
  • the battery pack 100 and thus the included battery cells, can be exposed to high temperatures that may degrade performance.
  • the packaging 110 of the battery pack 100 of the present invention preferably incorporates or comprises a heat deflective material that preferably at least partially surrounds a battery cell or cells 105 within the pack 100.
  • the heat deflective material has the ability to transfer heat away from the battery cells 105 while, at the same time, deflecting heat from outside the packaging 110 away from the battery cells 105.
  • the heat deflective material can be metallized, e.g., aluminized, polyester or polyethylene. It will be appreciated, however, that any other material that has the heat deflective properties described herein can be utilized as well.
  • FIG. 2 is a top view of an electronic device 200 that includes the battery pack 100.
  • the battery pack 100 can power the electronic device 200 or can be used merely for backup purposes.
  • the electronic device 200 may also include one or more heat generating components 210, such as power amplifiers or microprocessors, and a substrate 215, e.g., a printed circuit board, for providing electrical connections and mechanically supporting device components.
  • the heat generated by the component 210, and by any other components (not shown), is advantageously deflected by the packaging 110, a portion thereof, or a deflective material affixed thereto, so that the cell or cells 105 are not overheated and the performance is not degraded. This heat deflection also occurs when the device 200 is operated in a high temperature environment. As mentioned, heat generated by the cells 105 themselves is not held within the packaging 110, but is instead transferred outside the battery pack 100.
  • the packaging 110 can be formed entirely from the heat deflecting material.
  • the packaging 110 could include a first portion formed from a conventional material, such as a foil laminate, that does not deflect heat and a second portion formed from heat deflective material, such as an aluminized polymer.
  • the heat deflective material need not even be an integral part of the packaging 110.
  • another battery pack component could include heat deflective material, or the heat deflective material could be included as an extra component that does not necessarily provide a dual function and that is affixed to the interior or the exterior of the packaging 110. Such assemblies are described in greater detail below.
  • the battery pack 100 includes a conventional packaging portion 220 for surrounding regions of the cell or cells 105 that are not directly exposed to the heat generated by the heat generating component 210. Portions of the packaging that are directly exposed to the generated heat are formed from or incorporate the heat deflective material 225.
  • the non-deflecting material 220 and the heat deflective material 225 can be assembled together using conventional methods, such as by sealing the two portions with an adhesive or other sealant. In this manner, heat generated by the heat generating component 210 is conveniently deflected from the battery pack 100 and the cells 105 therein by a heat deflector 225 without having to form the entire package using heat deflective material.
  • FIG. 4 illustrates an embodiment of the present invention in which the battery pack 100 is entirely packaged with conventional material 220'.
  • a heat deflective portion 225' is affixed to the interior or the exterior of the conventional packaging 220' to deflect heat away from regions of the cells 105 that are directly exposed to the heat generated by the component 210.
  • use of a smaller amount of the heat deflective material 225' may be suitable for situations in which the battery pack 100 is exposed to heat coming from a small number of easily identified directions.
  • the heat deflective material 225' can be located only at specified areas of the battery pack 100 to deflect heat at reduced expense, as illustrated in FIG. 5.
  • FIG. 5 it can be seen that the heat deflective material 225' is wrapped around the periphery of the battery pack 100.
  • the heat deflective material can shield an individual cell 105 in addition to, or instead of, the battery pack 100.
  • a battery cell 105 such as a prismatic rechargeable cell, can be wrapped in heat deflective material 255.
  • the heat deflective material 255 can be a part of the cell packaging itself or can be wrapped around a previously packaged cell 105.
  • the heat deflective material 255 could be used to replace a conventional heat shrink material that might typically surround the cell 105 or a plurality of cells 105.
  • FIG. 7 shows a perspective view of a cell 105 that is packaged in a conventional manner.
  • the cell label 275 is formed from a heat deflective material.
  • the label 275 can be as large, or as small, as needed to deflect heat to which the cell 105 is exposed. Furthermore, a larger label 275 could adhere to more than a single surface of the cell 105, or multiple heat deflective labels could be applied.
  • a heat deflective label could be wound about the entire cell circumference, and it will be recognized that battery packs as well as cells could be labeled with heat deflective material.
  • heat deflective material can, as described above, be used in battery applications to deflect heat away from battery cells and thereby avoid degradation of performance that is caused by excess heat.
  • the heat deflective material can be formed as all or a part of the battery or cell packaging or as a label.
  • heat deflective material could comprise an additional component that is affixed to a complete cell or battery pack.
  • heat deflective material is beneficial for any type of energy storage device that is adversely affected by heat.
  • lithium ion, lithium polymer, nickel metal hydride, and nickel cadmium cells to name but a few, experience performance degradation when exposed to excess heat. Therefore, use of the invention described above can provide advantages for such devices.
