graphene in the aluminum mesh frame. The plate of the invention has
small thickness, low ohmic voltage drop, good porosity, and low
current loss. This reduces the electrolysis power consumption,
thereby significantly reducing the product cost and effectively
promoting the industrial production market of the sodium chlorate
electrolysis method. The plate also reduces energy consumption and
is environmentally friendly.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of Chinese Patent
Application No. 201811536160.2, filed on Dec. 14, 2018. The subject
matter thereof is hereby incorporated herein by reference in its
entirety.
FIELD
[0002] The present invention relates to a direct current-carrying
plate, and in particular, to a graphene ternary composite direct
current-carrying plate and application thereof.
BACKGROUND
[0003] Sodium chlorate electrolysis is produced by electrolyzing
industrial brine and is the main industrial production method. This
method consumes a large amount of electricity, and also consumes
about 5,500 kW and h/t in the electrolysis process. Furthermore,
the power consumption accounts for about 60% of the product
cost.
[0004] The electricity consumption for the production of sodium
chlorate depends on the level of the electrolyzer, the choice of
cell type and the advancement of electrolysis technology. The
current-carrying plate is an important part of the electrolysis
cell. The traditional bus-bar connection electrolysis technology
uses bolts or bus bars to connect the copper bars and aluminum
rows. The current loss of this technology is large, and there is a
short circuit of the electrolytic cells. This short circuit
seriously affects the normal operation of the equipment.
[0005] Nowadays, the direct current-carrying technology of the
baffle is used. This technique requires good conductivity and
mechanical strength of the baffle. The baffle needs to have a
certain porosity and lower ohmic voltage drop.
[0006] However, a graphene ternary composite direct
current-carrying plate, which may have a small thickness, a reduced
ohmic voltage, a good porosity and a small current loss, may be
beneficial.
SUMMARY
[0007] Certain embodiments of the present invention may provide
solutions to the problems and needs in the art that have not yet
been fully identified, appreciated, or solved by current
current-carrying plate technology. Some embodiments generally
pertain to a graphene ternary composite direct current-carrying
plate, which may have a small thickness, a reduced ohmic voltage, a
good porosity and a small current loss.
[0008] In one embodiment, a graphene ternary composite direct
current-carrying plate includes an anode plate and a cathode plate.
Graphene ternary composite direct current-carrying plate also
includes a graphene composite layer placed between the anode plate
and the cathode plate. The graphene composite layer includes an
aluminum mesh frame, with a certain proportion of the aluminum mesh
frame being doped with graphene.

Novel Graphene Ternary Composite Direct Current-Loading Plate of
the Invention Electrolysis power Electrolysis Scheme consumption
(kW h/t) efficiency (%) Scheme 1 4960 97 Scheme 2 5100 95
[0020] As shown in Table 1, the electrolysis power consumption of
the graphene ternary composite direct current-carrying plate is
above 4960 kW, h/t. Also, in these embodiments, the electrolysis
efficiency is above 95 percent, something that the conventional
technology cannot achieve.
[0021] Some embodiments of the present invention generally pertain
to a graphene ternary composite direct current-carrying plate that
includes a titanium plate and a graphene composite layer placed
between the anode plate and the cathode plate. The graphene
composite layer is doped with a certain proportion of graphene in
the aluminum mesh frame structure. The graphene ternary composite
direct current-carrying plate also includes a steel plate.
[0022] In an embodiment, the anode plate is a titanium plate, and
the cathode plate is a steel plate.
[0023] In some embodiments, the screen frame structure of the
graphene composite layer is rhombic, square, circular or
elliptical.
[0024] In certain embodiments, the graphene accounts for no more
than 10% by mass of the graphene composite layer.
[0025] In one embodiment, the direct current-carrying plate has a
thickness of 12-25 mm. In some other embodiments, the graphene
composite layer has a thickness of 3-5 mm.
[0026] In some additional embodiments, the titanium plate is a
titanium matrix ternary coating having a thickness of 1-5 mm, and
the steel plate is a thin steel plate having a thickness of 8-15

[0027] One or embodiment embodiments described herein may have the
following benefits:
[0028] In an embodiment, a direct current carrying technology of
the deflector is adopted, and a deflector may be required to have
good chemical stability and mechanical strength. The deflector may
have a certain porosity and have a low ohmic voltage drop.
[0029] In view of the above requirements, the graphene ternary
composite direct current-carrying plate, which adopts a titanium
matrix ternary coating and a thin steel plate to achieve high
chemical stability and mechanical strength of the deflector, may
include a graphene composite layer with an aluminum mesh structure.
Certain portions of the aluminum mesh structure may include
graphene. Graphene, which has good porosity and mechanical
strength, significantly reduces the thickness of the deflector.
[0030] The graphene ternary composite direct current-carrying plate
of may have a relatively small thickness, which reduces ohmic
voltage, provides good porosity and results in small current
loss.
[0031] In some embodiments, the electrolysis power consumption is
significantly reduced. This reduction in power consumption also
reduces the product cost, thereby promoting the industrial
production market of the sodium chlorate.
[0032] In some additional embodiments, energy consumption is
reduced, making the plate that much more environmentally
friendly.
[0033] It will be readily understood that the components of various
