TITLE
Printed battery holder for coin cells
CROSS-RELATION TO OTHER APPLICATIONS
[0001] None
FIELD OF THE INVENTION
[0002] The present disclosure relates to battery holders for at least one coin battery, wherein the battery holders are made of paper or plastic materials and printed conducting layers.
BACKGROUND OF THE INVENTION
[0003] Electronics, printed on paper or plastic, is becoming increasingly popular. This kind of electronics is termed as Paper Electronics or Plastic Electronics. For this new technology, electrically conducting traces are printed on a plastic or paper substrate by using conducting inks. There is always a need to electrically connect commercially available coin battery holders to paper or plastic, which is a very complicated process and hence expensive. Commercially available battery holders are made of rigid materials and can be connected to a device by using wires or by using solder paste. Connecting wires or applying solder paste on paper or plastic is not an easy process. Therefore, there is a need to have a battery holder that is compact and is made of a paper and/or plastic. There have been some attempts made to create a battery holder based on flexible substrate, as disclosed in US Patent publication no. US 2014/0147719 A1 and US 2014/0199572 A. But in both these cases, the battery is required to be inserted into the flexible battery holder during the preparation of the holder itself. The battery can’t be removed and a new battery can’t be inserted into these battery holders.
SUMMARY OF THE INVENTION
[0004] The present invention relates to a battery holder for holding at least one coin battery. The battery holder comprises a bottom substrate made of plastic or cardboard or paper. On a surface of the bottom substrate is provided a first conducting layer and a second conducting layer. The first conducting layer is touching a bottom terminal of the coin battery. The battery holder further comprises a flexible plastic substrate. The flexible plastic substrate has a first surface and a second surface. A third conducting layer is provided on the flexible plastic substrate in such a way that a first portion of the third conducting layer is touching a top terminal of the coin battery. A second portion of the third conducting layer is electrically connected to the second conducting layer. The battery holder further comprises a housing which is made of plastic and/or paper. The housing comprises a slot to hold the battery and an opening. The opening is connected to the slot. The opening is used to insert the battery into the slot or to remove the battery out of the slot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[00010] The invention will now be described in detail. Drawings and examples are provided for better illustration of the invention. It will be understood that the embodiments and aspects of the invention described herein are only examples and do not limit the protector’s scope of the claims in any way. The invention is defined by the claims and their equivalents. It will be understood that features of one aspect or embodiment of the invention can be combined with the feature of a different aspect or aspects and/or embodiments of the invention.
[00011] The present invention is about a battery holder for coin cell battery. A coin cell battery is defined by a battery having the shape of a coin i.e. a cylindrical shape. The battery holder 100 comprises a bottom substrate 120, as shown in Fig. 1A. The bottom substrate 120 can be made of plastic or paper material and is electrically non-conducting. On a surface 125 of the bottom substrate 120 is provided at least two conducting layers - a first conducting layer 121 and a second conducting layer 122. In a non-limiting aspect, the first conducting layer 121 and the second conducting layer 122 are produced by printing a conducting ink on the surface 125. The first conducting layer 121 is touching a bottom terminal 110a of a coin battery 110 and hence electrically connect to the bottom terminal 110a. Typically, in a coin battery 110, two terminals (positive and negative) are at the opposite sides of the coin battery i.e. a bottom terminal 110a and a top terminal 110b. In a non-limiting aspect, two or more coin batteries are placed in the battery holder 100 in such a way that they are stacked one over another in series connection. The second conducting layer 122 is to electrically connect the top terminal 110b of the coin battery 110. The first conducting layer 121 and the second conducting layer 122 are used to get the electrical contacts of the two terminals (110a, 110b) of the coin battery (110) out of the battery holder 100. The battery holder 100 further comprises a flexible plastic substrate 130. The flexible plastic substrate 130 has a first surface 135 and a second surface 136. In a non-limiting aspect, the thickness of the flexible plastic substrate 130 is in the range of 50-300 micrometers. In a preferred aspect, the flexible plastic substrate 130 is made of polyethylene terephthalate (PET). A third conducting layer 140 is provided on the flexible plastic substrate 130 in such a way that a first portion 140a of the third conducting layer 140 is touching the top terminal 110b of the battery 110 and a second portion 140b of the third conducting layer 140 is electrically connected to the second conducting layer 122. That means the purpose of the third conducting layer 140 is to electrically connect the top terminal 110b of the coin battery 110 to the second conducting layer 122. In an embodiment as shown in Fig. 1 A, the first portion 140a and the second portion 140b are printed on the second surface 136 of the flexible plastic substrate 130 and a third portion 140c of the third conducting layer 140 is printed on the first surface 135 of the flexible plastic substrate 130. The third portion 140c is connected to the first portion 140a and the second portion 140b via a first though-connection 141 and a second though-connection 142, respectively. Though-connection is made by making a hole or a cut on the flexible plastic substrate 130 and filling the hole or the cut with a conducting ink. In order to make the physical contact between the second portion 140b and the second conducting layer 122, a conducting adhesive layer 160 may be provided between the second portion 140b and the second conducting layer 122. The conducting adhesive layer 160 comprises at least one adhesive polymer and at least one adhesive conducting particles. The at least one adhesive polymer can be hot-melt polymer which can become sticky after heating it up above 50°C. A housing 150, mage of non-conducting material, is fixed on the surface 125 of the bottom substrate 120. The housing 150 comprises a slot 151 to hold the coin battery 110 and an opening 152, connected to the slot 151, to insert or remove the coin battery 110 from the slot 151. The slot 151 is made in such a way that it can accommodate the coin battery (or batteries) 110 as well as some part of the flexible plastic substrate 130. When the coin battery 110 is inserted into the slot 152 via the opening 152, the flexible plastic substrate 130 bends to accommodate the coin battery 110 in the slot 151. In a preferred aspect, the shape of the slot 151 is cylindrical and the diameter of the cylindrical slot is slightly bigger that the diameter of the coin battery 110 and the height of the cylindrical slot is slightly bigger than the thickness of the coin battery 110.
[00012] Fig. IB shows a cross-sectional view of a further aspect of the battery holder 100. In this aspect, the third conducting layer 140 differs from the third conducting layer 140 of the aspect shown in Fig. 1 A, as described below.
[00013] In the aspect, shown in Fig. IB, the third conducting layer 140 is provided on the second surface 136 of the flexible plastic substrate 130. That means, the first portion 140a, the second portion 140b and the third portion 140c of the third conducting layer 140 are on the same surface (the second surface 136). There is no through-connection (141 and 142) in this aspect.
