Deliverables

Propose a new method and/or technology that will shut down or greatly reduce the power output of primary alkaline batteries in the event of a direct short.  As a recap, here are the conditions that must be met:

  • Your idea must initiate / only function in the following range: > 80 degrees C, < than 110 degrees C
  • Your idea must exist inside the cell: as such, you will be constrained by commercial battery size
  • The solution must be stable in a high alkaline environment
  • The solution may be reversible or permanent

**Top submissions will provide verbal and/or visual evidence that the idea proposed is feasible. 

Considerations:

Your idea should go above and beyond the following technologies that we are already aware of:

  • Bimetallic switches
  • Fuse / tab meltdown
  • Shutdown separator
  • CID (current interrupt device)
  • Polymeric overcurrent protector

Submissions will be graded on the following criteria:

  • Meets Deliverables
  • Creativity
  • Clarity
  • Manufacturability
