Ceramic Packaging Technology for All-Solid-State and Rechargeable Batteries

Improve the Reliability of Rechargeable Batteries with Surface Mount Ceramic Packages Improve the Reliability of Rechargeable Batteries with Surface Mount Ceramic Packages

New Ceramic Packaging Technology Features Environmental Resistance

Encapsulating existing power devices, such as rechargeable batteries and capacitors, in Kyocera's ceramic packages can increase their usage life. As a result, ceramic packaging solutions are optimal for the small rechargeable batteries for IoT and other emerging fields where devices need to withstand harsh environments.

The Coming IoT Era
of Surface-Mounted Small Power Devices

IoT is the concept whereby everything in daily life connects via the Internet, including buildings, home appliances, and automobiles.
Surface-mounted small power devices are an indispensable part of this future, and as such, will be in high demand.

Conquer the Disadvantages of Lithium-ion Secondary
Batteries by using All-Solid-State Batteries

Batteries that are no longer usable after discharge, such as dry cell batteries, are called primary batteries, and those that can be recharged repeatedly are called secondary batteries. Among secondary batteries, lithium-ion batteries are currently the mainstream. However, while lithium-ion secondary batteries can charge and discharge at high outputs, their application presents two major challenges.

Disadvantages of Lithium-ion Batteries

  • 1Safety risks from heat generation, fuming, ignition, or explosion
  • 2 Narrow usable temperature range
Lithium-ion Batteries Lithium-ion Batteries

All-Solid-State Batteries can conquer these challenges. Since they are made from non-flammable solid electrolytes - as opposed to the flammable liquid electrolytes in Lithium-ion batteries - All-Solid-State Batteries offer clear advantages over alternatives.

Advantages of All-Solid-State Batteries

  • 1Safety
  • 2Wide usable temperature range
  • 3Longer expected usage life

However

Depending on the type of solid electrolyte used in an All-Solid-State Batteries, there are additional challenges to implementation, such as deterioration due to moisture.
In addition, All-Solid-State Batteries for IoT device applications require reflowable surface-mount structures and small and thin shapes.

Developing new packaging technologies
is equally as crucial as surface-mount small power devices!

    Design customization available
Seam Sealing※ Advantages
Seam Sealing Seam Sealing Seam Sealing
  • Lower heat load on contents due to local welding
  • Prevent aging and performance deterioration
  • Available for small and thin shapes
  • Optimal for products requiring high airtightness and moisture resistance
  • Seam weld sealing is a technology that blocks parts in a package from the outside air to ensure stable operation for an extended period of time.
    Parts are sandwiched between two metals, and current is applied to weld them.
