Electrolysis Electrodes: Mesh Vs. Solid

Misinformation

There’s a number of misinformation in the ionized water industry concerning the relative deserves of solid vs. mesh electrolysis electrodes. Images of corroded or calcified mesh electrodes, as well as misleading information in regards to the superiority of strong plates, will be seen on the websites of many Enagic distributors. Many declare that solid electrodes are more durable, have larger longevity, and merely last longer. It is usually falsely claimed that strong electrodesare stronger and might withstand the excessive energy needed to “ionize water”; whereas, the “flimsy” ‘mesh’ electrodes rapidly degrade: a strong piece of steel can withstand greater than a flimsychain-link fence (though the Enagic stable electrodes are only about the thickness of a credit score cart, which one could additionally say is “flimsy”).

Electrolysis Electrodes: Mesh Vs. Solid

Fact

In actuality, a properly designed mesh electrode for electrolysis of water might not only final longer, however it’s well known in other industries to be the best. Indeed, mass manufacturing of hydrogen gas, oxygen gas, era of chlorine/hypochlorous acid, as nicely as the production of sodium hydroxide and hydrogen peroxide,all use and concentrate on a mesh kind design. The reason is because a mesh design is way more environment friendly with lower resistivity (much less heat leading to much less degradation)in comparison with strong electrodes. (*see references at finish of article).

The textbelow is from a scientific article (Sullivan, J. et al.)showing that you’ll get the next current density (at the same applied voltage) with mesh plates in comparison with different types:

Further, as stable electrodes don’t have any way to arrange or channel the current being delivered, solid electrodes have an inconsistent saturation of electrons. Electrons transfer across the stable electrode finding the trail of the least resistance. Generally, this would lead to an inconsistent supply of power and fewer environment friendly and efficient electrolysis outcomes. This concept is very crucial to redox potential efficiency.

Mesh electrodes pressure the present to be organized by offering more “channeling” to direct the electron flow. The utilized current or energy very evenly saturates the mesh-electrode, which increases the quantity of surface space that is receiving the electrical present that’s used for electrolysis.

Another scientific article (Zang, Y. et al.Penn State University) states:

Mesh cathodes…provide a better surface area materials than flat plate electrodes…Cyclic voltammetry tests confirmed that the electrochemically active floor area of [mesh] may very well be 3 times larger than a flat sheet.

Here aresome more scientific articlesunrelated to the alkaline water ionizers that also demonstratethe superiority of mesh over strong electrodes:

The next graph validates the power of mesh electrodes to achieve target current densities at decrease applied voltages, titanium wire therefore demonstrating their larger efficiency compared to solid electrodes:

Patents on mesh electrode design

Here are only a few patents that each one use the mesh design for electrolysis exterior the alkaline water ionizer trade because mesh is more environment friendly:

The Enagic unit is still clearly effective with the solid electrodes, but the reality is, stable is not necessarily a better design. In fact, compared to a poorly-designed mesh it could possibly be. Perhaps the true motive that Enagic doesn’t use mesh plates is as a result of mesh electrodes for water ionizers is a patented know-how, and subsequently Enagic would infringe on that technology in the event that they tried to use it.

Corrosion/degradation of electrodes

Finally, pictures of corroded and calcified mesh electrodes may be widely seen on the web, decrying the inferiority of the mesh electrode design. The next is a typical example:

But in actual fact, photos equivalent to these only exhibit what happens when ionizers are usually not properly maintained or don’t make use of anti-scaling expertise, resulting inelectrode calcification (limescale). The “sludge” buildup causes the plates to heat up, eventually debonding the platinum coating. Any electrode design, no matter whether or not it is strong or mesh, is inclined to this phenomenon if not properly maintained. The following pictures are from an precise SD501 with strong plates, showing both calcification (left) as well as exposed titanium (right):

Therefore, both stable and mesh electrodes are susceptible to the identical degradation, titanium sheet especially if there is no such thing as a anti-scaling system to forestall calcium buildup.

In mild of this data, it may be seen that there is no inherent inferiority with a mesh-kind electrolysis electrode, and the proof exhibits that mesh electrodes are widely used all through varied industries utilizing electrolytic processes. As is the case with any technology, both electrode design (strong or mesh), if poorly designedor improperly maintained, can consequence in the manufacturing of lower high quality/therapeutic water.
