Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an electric characteristic
modifying material which prevents deterioration of a secondary
battery and reduces electric resistance of a conductive portion in
metallic wiring and the like of electric appliances.
[0003] 2. Description of Related Art
[0004] Conventionally, various kinds of apparatus and devices are
mostly electrical. Not only an industrial large machine which
consumes a large amount of electricity but also portable telephone
and the like which consume a small amount of electricity are not
established if no electricity is used.
[0005] Not so few electric apparatuses and devices employ chemical
batteries.
[0006] The chemical battery is largely classified into a primary
battery and a secondary battery, both of which adopt the same
method of converting chemical energy to electric energy. Oxidant is
used as anode activating material while reducing agent is used as
cathode activating material. The both electrodes are placed in ion
conductor (electrolyte water solution or non-aqueous electrolyte)
such that they oppose each other and an outside load is applied to
the both electrodes. Consequently, electron accepting reaction
(reducing reaction) occurs at the anode and electron emitting
reaction (oxidation reaction) at the cathode, so that electrons
move from the cathode to the anode through the outside load.
Consequently, current flows from the anode to the cathode.
[0007] Because ion moves in the ion conductor, current flows.
[0008] Discharge phenomenon is generated by electric chemical
reaction and active material is consumed by discharge. A battery to
be thrown away when the discharge is not induced any more is called
the primary battery. A battery in which if the active material is
consumed completely, electricity is supplied from outside so as to
reproduce the active material, thereby ensuring repeated use
thereof is called the secondary battery.
[0009] The secondary battery includes lead acid battery used in
such apparatus and devices as automobiles and alkaline battery used
for such small devices as electronic devices. Of the alkaline
batteries, a type using lithium as the active material has
attracted public attention with prevailing of portable phones and
notebook type personal computer because it is the lightest and
small.
[0010] The inventor of the present invention has not surveyed
preceding technologies at research/development stage and patent
filing stage. Therefore, he does not have any knowledge about the
preceding technology which should be mentioned here.
[0011] Chemical reaction at the time of the discharge or recharge
accompanies deposition or decomposition of electrolyte and if the
discharge or recharge is repeated, crystal of deposited material is
grown gradually and it never returns to its original state.
Consequently, the capacity and electromotive force of the secondary
battery drop, and therefore the battery needs to be replaced.
[0012] Further, a portable apparatus or device has a problem of
battery runout when used outside of home or office. Electricity
saving in the apparatus and device has been demanded to prolong
their continuous usage time.
SUMMARY OF THE INVENTION
[0013] In views of the above-described problem, according to the
present invention, radioactive substance is fixed to a sheet-like
material and this sheet-like material is bonded to an apparatus or
device. Alternatively, radioactive substance is mixed in raw
material resin and part of an apparatus or device is formed with an
obtained compound. Or radioactive substance is mixed in paint and
an apparatus or device is coated with this paint. Consequently, in
case of a secondary battery incorporated in the apparatus or
device, ions or deposit in an ion conductor is excited with
radioactive ray so as to intensify chemical reaction activity of
the ions or deposit, thereby preventing growth or excessive
expansion of the deposit or crystal. In case of the conductor such
as metallic wiring in an apparatus or device, bonding electrons in
metallic wiring are excited so as to increase the degree of
freedom, thereby reducing electric resistance of the conductor. As
a result, the above-described problem is solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Hereinafter, the embodiment of the present invention will be
described in detail with reference to the accompanying
drawings.
[0019] As shown in FIG. 1, in the electric characteristic modifying
material 1 of the present invention, radioactive substance 4 is
fixed on the surface of a sheet material 3 using adhesive agent
made of epoxy resin or the like.
[0020] An adhesive layer 5 is provided on the rear surface and the
surface of the adhesive layer 5 is covered with a separation paper
6.
[0021] Any sheet material 3 may be used as long as it is plastic
and for example, metallic foil, resin film, unwoven cloth and the
like are permissible.
[0022] The radioactive substance 4 emits an ultra small amount of
radioactive ray which does not affect the human body and for
example, radium, radon and the like can be mentioned. Although
there is no limitation on which it is natural ore or refined
product, one in a form of fine powder is preferable.
[0023] It is permissible to mix ceramics powder 7 in the
radioactive substance 4 and as shown in FIG. 2, with the ceramic
powder 7 as aggregates, porous radioactive layer 8 containing the
radioactive substance 4 is formed on the surface of the sheet
material 3.
[0024] The kind of the ceramics powder 7 is not restricted to any
one and for example, silica, alumina, zirconia and the like are
permissible.
[0025] Upon use, the separation paper 6 is remove and then the
adhesive layer 5 on its rear surface only has to be pressed against
an object. For example, when it is employed for the portable phone
T, it is bonded to an inner bottom of an accommodating portion of
the secondary battery B (see FIG. 3).
[0026] Next, a modification example will be described.
[0027] The electric characteristic modifying material 1 of a first
modification is produced by mixing the radioactive substance 4 in
the raw material resin 9 and forming the obtained compound into a
desired shape. For example, in case of the portable phone T, it is
formed into the configuration of a lid 10 of the accommodating
portion in the secondary battery B (see FIG. 3).
[0028] The raw material resin 9 may be of any kind if it can be
formed into an appropriate configuration, and for example,
thermoset resin such as phenol resin, formaldehyde resin, urea
resin, silicon resin, and thermoplastic resin such as polyethylene,
polystyrene, poly methyl methacrylate and photo-setting resin such
as polyurethane methacrylate, oligoester methacrylate,
urethanacrylate, epoxyacrylate, photosensitive polyimide,
aminoalkyd can be mentioned.
[0029] In the electric characteristic modifying material 1 of a
second modification, the radioactive substance 4 is mixed with a
paint 11. As the paint 11, any well known one may be used whether
it is organic or inorganic.
[0030] Upon use, the paint 11 is applied to an inner surface of the
lid 10 of the portable phone W, for example (see FIG. 4).
[0031] Next, an operation of the electric characteristic modifying
material of the present invention will be described.
[0032] The radioactive substance 4 in the electric characteristic
modifying material 1 always emits radioactive ray.
[0033] Ions in the icon conductor of the secondary battery B which
receives this radioactive ray likely generates chemical reaction
because valence electron is transited to excitation state.
[0034] Therefore, generation velocity of deposit due to chemical
reaction upon discharge increases and therefore, crystal growth is
suppressed, so that crystal is never expanded too much.
[0035] Further, the generated deposit is decomposed easily by
exchange of electrons because bonding electron is excited due to
reception of radioactive ray.
[0036] On the other hand, conductors in various circuits and
wirings in an electric apparatus or device are made of metal and in
metal, a number of atoms are coupled by free electrons. Thus, if
the conductor receives radioactive ray from the radioactive
material 4, the free electrons relating to such metallic coupling
are excited. Because those excited electrons have a higher kinetic
energy than electrons in ground state, when a voltage is applied to
the conductor, free electrons move easily.
[0037] Therefore, electric resistance of the conductor drops as
compared to a case where no radioactive ray is received.
[0038] In conclusion, the present invention is accomplished by
fixing the radioactive substance 4 to the sheet material 3 and
therefore, only by bonding an embodiment of the present invention
to various kinds of electric apparatus or device, deterioration of
the secondary battery B used in the apparatus or device can be
prevented and electric resistance of circuits and wirings in the
apparatus or device can be decreased, thereby achieving power
saving of the apparatus or device and extending its continuous use
time.
[0039] Further, if a deteriorated secondary battery B is used in an
apparatus or device on which the embodiment of the present
invention is bonded, deposit which has been generated in the ion
conductor of the secondary battery B and grown to be substance hard
to decompose is decomposed easily due to an action of radioactive
ray. Therefore, the storage capacity and electromotive force of the
second battery B can be recovered.
[0040] If the sheet-like material 3 is formed into a narrow tape,
for example, it can be wound around a power transmission line from
an electric power station so as to suppress drop in voltage.
Consequently, power loss in transmission of electric power to a
remote place is small, thereby contributing to energy saving.
[0041] In the above embodiment, the radioactive substance 4 is
mixed with the raw material resin 9 and the obtained compound is
formed. For example, if a sheath case of an electric apparatus or
device is formed, radioactive ray is emitted from the sheath case.
Therefore, the sheath case itself can be supplied with functions
for preventing the deterioration of the secondary battery B and
reducing electric resistance thereof. Consequently, there is no
feeling of disharmony on its appearance and the same effect as
described above can be obtained.
[0042] Because the compound is obtained by mixing the radioactive
substance 4 with the paint 11, it only has to be applied and can be
used for existing apparatus, device and equipment.
[0043] Although the conductor in the secondary battery B or
electric apparatus or device is heated when supplied with
electricity, the radioactive layer 8 containing the radioactive
substance 4 turns to porous because the ceramics powder 7 is mixed
with the radioactive substance 4, so that its specific surface area
is increased and heat radiation efficiency is improved. Therefore,
drop in electromotive force of the secondary batter B and rise in
electric resistance of the conductor due to heat can be suppressed,
thereby indicating that practical effect of the present invention
is very large.
