Selling Points for Lithium Battery Seals

Lithium battery seals employ the incredibly dynamic hermetic seal technology, which effectively makes the objects that are protected by them airtight. These seals can be applied to a large number of materials and are employed in a vast range of industries.

How Are Lithium Battery Seals Designed?

In the lithium battery design, the cells are all individually sealed and cannot leak. This benefits users because there is no restriction orientation of a lithium battery, which means that the battery can be installed upside down or on its side.

Hermetic connectors are a special class of sealed connectors that incorporate glass-to-metal or other highly-engineered sealing technology. Hermetic seal connectors are versatile and dynamic and are employed in a number of diverse applications, including submarines and satellites.

Whether you’re talking about hermetic seals and feedthroughs, battery seals, connectors or any other type of hermetic technology, this type of sealing is designed to ensure an absolute line of demarcation between the object and any other elements.

How Important Are Lithium Battery Seals?

Lithium battery seals prolong the life of your battery. Battery end seals also help to ensure that the battery doesn’t get too hot. The seals also prevent the emission of harmful gas and liquids.

The Lowdown on Lithium Battery Seals

Lithium battery seals are critical components in many types of batteries. From medical equipment to weapons control systems, these batteries must serve as essential power sources. With durability, dependability and power output as important performance indicators, batteries’ seals should adequately support their functionality. In this short guide, you’ll learn about the advantages of battery seals constructed from lithium.

Benefits of Lithium Battery Seals

Battery end seals serve an important function: keeping a battery’s electrolyte and internal components inside its housing. A battery end seal ensures that its power cell stays reliable, functional and safe for ongoing use. Battery seals come in a wide range of materials:

  • Titanium alloys
  • Stainless steel
  • Aluminum
  • Steel alloys
  • Lithium

Complete Hermetics manufactures several lithium battery glass-to-metal sealed lid products. Glass-to-metal seals offer unique advantages. Their construction creates a reliable high-quality seal that withstands exposure to harsh conditions, including temperatures between -40°C and +150°C. They also resist humidity extremes, electrochemical corrosion, pressure variation and high-voltage electrical currents. Lithium seals offer excellent performance in all these areas, along with offering a longer shelf life.

A Quick Overview of Battery End Seals


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.

What Are Lithium Battery Seals?

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.
