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.

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.
