Market Status and Incumbent Technologies

Battery-life Enhancement 

The key to unlocking the best batteries with x5-10 more energy storage capacity and useful life fundamentally depends upon stabilization of lithium during charge and discharge cycles.  Stabilizing lead and nickel electrodes will lead to similar gains in those established battery technologies as well.  With continued use and expected charge/discharge cycles, the originally smooth electrode surface is replaced by the growth of metallic dendrites that decrease battery performance, damage internal battery components, and particularly with lithium, pose an explosion hazard.  This problem is significantly worse in lithium-metal batteries and currently prevents their use beyond 5-10 total cycles despite their significantly greater energy density.

Alligant Battery Healing

Alligant’s technology suppresses the growth of metal dendrites to maintain battery performance, whether lithium-ion, lithium-metal, or lead-acid, across significant additional cycles.  Alligant’s technology has the potential to make lithium-metal batteries commercially viable as a practical, safe, higher energy replacement for lithium ion. Yet it can also be applied to conventional battery systems to achieve similar benefits.

Bonding, Welding, Brazing, Soldering 

In an era where materials technology has evolved rapidly in a few decades, the welding industry has struggled to adapt and few fundamental changes have been seen over the last century.  The result is a list of advanced materials with incredible potential and affordability, yet they largely remain unused because manufacturing capabilities have not kept pace.  Even the newest welding technologies, such as laser welding and friction stir welding, still fundamentally depend upon the application of intense heat and pressure that damages the useful properties of advanced alloys, prevents reliable bonding of dissimilar metals, and even slightly different grades of like-metals.  Advanced gluing techniques depend upon folding of the metal around the joint to achieve acceptable bonding strength.

Alligant Automated Materials Joining 

Requires no heat or pressure and provides the manufacturing industry with the tools it needs to work with advanced alloys, dissimilar metals, and metal composites like carbon-fiber/aluminum.  Alligant’s technology decreases costs and simplifies personnel and manufacturing floor requirements by transitioning the industry from centuries old methods to computer automation and integrated quality control, fewer power requirements, no generation of dangerous metal particulate fumes, intense heat and ultra-violet light, nor dangerous voltages or current.

In sharp contrast to today’s methods, Alligant’s Automated Joining solution requires low skill labor and operators are only used to initiate the process and respond to any system alerts and to process completed parts.

Nondestructive Evaluation (NDE)

Conventional non-destructive material integrity validation techniques are difficult to implement on a case-by-case basis. They are typically deployed in assembly line manufacturing, especially of smaller components where measurement conditions are controlled and consistently measured.  Analysis of larger, more complex, or live (in use) objects degrades the reliability of or, due to cost, functionality and accuracy, negates, the use of incumbent methods all together.  Therefore, for example, despite the availability of infrared thermography, radiography, acoustic and magnetic MIV tools, ~80% of weld QC evaluation still depends upon destructive analysis methods.

Alligant Integrity Validation Unit (IVU)

In contrast to today’s available technologies, Alligant’s approach to non-destructive material integrity validation is easy to apply to a wide range of components and environments with predictable cost and outcome.  In a departure from the incumbent technologies, Alligant’s IVU carries none of the safety concerns due to x-ray radiation (CT/radiography), works on materials other than steel that do not contain significant magnetic properties (eddy current analysis), and can be used to measure live components in thermally or acoustically ‘noisy’ environments (infrared thermography, acoustic emission).  Further, the method may incorporate all the benefits of computer monitoring, statistical analysis, and automation in combination sub-second imaging analysis of the area of interest.

Alligant’s IVU gives customers the ability to centrally and remotely monitor structures and operating environments or evaluate a live object and perform a quick measurement that reveals high resolution information about are area of material, its internal and external surfaces, and any cracks, pores or other disruptions that may be present.

Anticorrosion Techniques 

The economy bears an annual cost of $1 Trillion to maintain its network of pipelines, industrial plants, oil rigs, buildings, bridges, ships and other infrastructure due to corrosion.  The most effective preventative tools can be described as coatings and electrochemical countermeasures.  Coatings must be specifically tailored to resist their environment while adhering well to the protected surface and consequently there is no single coating that works well across multiple applications.

With few exceptions, linear corrosion, the predictably slow and relatively even loss of material across a surface, is much less concerning than the accelerated corrosion that occurs in isolated areas of a material’s surface due to initial pitting.  The protective properties of any coating are circumvented by a single exposed area (pit) of the surface, no matter how small: pitting begins at a compromised point in the coating and metal begins to corrode out from underneath the surrounding coating area through this single access.  As the surface area of the pit grows the corrosion rate increases and instead of slow and even loss, a structurally compromised area is rapidly created. Electrochemical countermeasures do not necessarily avoid this process and instead suppress linear corrosion by decreasing the surface voltage at a protected area below the voltage of corrosion.  However, the power requirements and effectiveness can vary significantly with fluctuations in the surrounding environment.

Alligant Active Corrosion Suppression

Alligant’s process can be deployed with or without surface coatings or conventional electrochemical anti-corrosion systems as necessary to dramatically suppress pitting and suppress the costliest forms of corrosion. The corrosion suppression system is deployed applying contacts to the target materials and runs continuously while being monitored from remote terminals providing the customer with information about any changes in a material’s surface.

Finishing Technologies

Many parts requiring plating have complex designs, recesses and even holes that need to be coated and finished thinly and evenly. Flat surfaces are relatively easy to plate, but recessed areas, corners and holes present incumbent solutions with a significant challenge. Incumbent solutions result in coating thickness variations across the part as it encounters flat surfaces, corners, holes and recesses on the same part. The component may require a plating thickness of 1.5 mils overall, but on high current density areas, the thickness of the plated metal may exceed 8.0 mils. These thickness variations cause performance and long term quality and durability issues in addition to resulting in several unnecessary costs, including waste of plating energy, time, raw materials and rejected production parts.

A flat part, such as a printed circuit board (PCB), has few recesses and usually much less plating thickness variation, but its design and shape present other problems. Plating thickness on trace heights, isolated component pads and blind holes on different areas of the part can vary so significantly that it creates functional problems with current carrying capability, impedance matching, solder mask application and the assembly of components.

Alligant Precision Finishing

Alligant’s finishing solution plates new metal evenly across edges, joints, holes and other non-symmetric features of a workpiece. It is also capable of smoother electro-forming over edges of molds (molds are often made more multiple pieces attached together, and metal doesn’t plate well over the seams of the mold). Alligant’s solution dramatically improves deposit evenness while reducing total plating. Alligant’s technology can be applied to electroless chemistry. Alligant is uniquely capable to accomplish even and consistent quality of plating through-holes on PCBs and is capable of controlling surface smoothness for finishing, or micro/nano wire growth.

All of this adds up to a significant advantage for Alligant on both finished product performance and quality as well as ongoing parts and labor costs for PCB manufacturers.
