A Quick Overview of Battery End Seals

Posted by admin on

 

Battery end seals play important roles in battery life, functionality and power delivery. They create tight seals that stop any unusual loss of electrical energy. With missing or damaged end seals, batteries lose power faster than usual and their typical lifespans decrease.

Lithium Battery Sealed Lids

Hermetic seal technology is key with lithium battery sealed lids. Glass-to-metal sealing techniques require both the glass and the metal to have similar thermal expansion properties to ensure a solid seal when the pieces cool down.

To create a hermetic seal, glass must first be heated to a molten consistency. This occurs at between 1,400 and 1,600 degrees Celsius. Once this happens, the glass can be wetted to the metal. Wetting contacts a liquid with a solid surface through intermolecular interactions. Cohesive and adhesive forces must balance adequately for wetting to succeed.

When the glass-to-metal sealing process is complete, you have a high-quality seal that can handle extreme conditions. Besides mitigating power loss, a good hermetic seal also protects against water and foreign body entry.

Dependability and Durability

Lithium batteries have a wide range of applications. Both durability and reliability are key when it comes to battery end seals. Whether on batteries powering pacemakers, weapons systems or other critical pieces of equipment, Complete Hermetics produces consistently high-quality hermetically sealed components.

A Quick Primer on Hermetic Seals and Feedthroughs

Posted by admin on

 

As you may know, hermetic feedthroughs allow energy or substances to migrate from outside a hermetically-sealed area to the inside. Maintaining hermetic seals is important with a feedthrough, but providing electrical isolation is also key. Strict performance standards call for no leakage while ensuring that a powerful vacuum remains.

Constructing Hermetic Feedthroughs

A hermetic feedthrough is created using similar techniques to creating hermetic seals. Its glass-to-metal construction incorporates molten glass that can be bonded tightly to metal. To achieve this feat, the glass must be heated to between 1,400 and 1,600 degrees Celsius. Some feedthroughs incorporate ceramic-to-metal or electrical sealing. Hermetic feedthroughs can fall into one of three unique categories:

  • Low-voltage
  • Water-cooled/RF
  • High-voltage

Critical Performance Standards

A high-quality feedthrough can resist extreme temperature shifts, changes in pressure and huge swings in humidity levels. When plated, feedthroughs can also resist corrosion and handle wire bonding or soldering. Depending on product specifications, a feedthrough may need to tolerate even more extremes without so much as a tiny amount of leakages. For feedthroughs used in medical equipment, such super-strict production standards are necessary.

Complete Hermetics develops and manufactures hermetic seals and feedthroughs that deliver the dependability and durability needed in your applications. Besides our standard feedthroughs, we can also design custom versions that meet your needs.

What Are Lithium Battery Seals?

Posted by admin on

Lithium battery seals preserve battery life by preventing the loss of electrolytes. A lithium battery glass-to-metal sealed lid is extremely effective in making a good seal.

Why Lithium Battery Seals Are Important

During normal use, a battery generates gas. This won’t be a problem unless the pressure inside the battery gets too high. Without a way to release the gas, the cell could rupture and damage the battery.

Specially-made battery end seals solve this problem by providing a low-pressure venting system. The battery end has a gasket that seals onto the cell. That gasket has a vent mechanism to release pressure, protecting the battery from damage.

Caring for a Lithium Battery

Lithium battery seals prolong the life of your battery but you can also protect it by making sure it doesn’t get too hot. Keep these things in mind:

  • Provide space between the battery and any heat source.
  • Keep your battery away from transistors and transformers.
  • Try to keep your battery between 20-25 degrees Celcius.
  • Place your battery near an air inlet rather than an exhaust vent.

We offer a wide range of sealing technologies, including glass-to-metal lids that are highly reliable and can handle high electrical currents as well as electrochemical corrosion. If you are looking for a custom-made product, contact us.

Custom Hermetic Feedthroughs

What Are Electrical Feedthroughs For?

Posted by admin on

You might not think that there are many components that can be found in X-ray machines, transformers and furnaces. But electrical feedthroughs are commonly used in a wide variety of technologies to help make sure that electricity doesn’t escape and cause malfunctions. It is important to know what these feedthroughs are used for and to appreciate this important piece of technology that keeps so many different technologies running.

The Importance of Vacuums 

Creating a vacuum guarantees that the electricity being transported from one part of a machine to another does not get out. Vacuum feedthroughs effectively make sure that the electricity is distributed safely.

Using Seals

The key to creating a vacuum is the type of seal that is used. Hermetic feedthroughs use glass-to-metal seals and ceramic seals to create this vacuum. When building a new seal, it is extremely important that the materials used are able to withstand intensive use and not break down over time.

This is why many seals are made with glass and ceramics; these materials are designed to withstand extreme temperatures, as well as other wear and tear. Many of these seals are used in technology like furnaces that operate at extreme temperatures. Making sure the seals do not break down easily will make sure the machine runs smoothly.
