Technology

Two Patented Technologies. One Unbeatable System.

MIL-standard cases in development

Fibercon Altilium CP Blanket (FACB)

The FACB is BUNCKER®’s proprietary thermal and chemical insulation layer. Developed in partnership with Fibercon and Altilium, it provides dual protection: thermal barrier and chemical filtration in a single material.

  • Neutralises hydrofluoric acid (HF) gas, the most hazardous thermal runaway by-product
  • Maintains outer surface below 100°C during full thermal runaway events
  • Continuously controls and contains thermal runaway events
  • No replacement filler material the blanket does the work
  • Certified and tested to UN LP906 standards

Patented Bell Jar Design

The bell jar architecture is the structural innovation that makes BUNCKER® unique. The design creates a sealed containment environment around the battery without requiring any filler material to achieve containment.

  • Patented design no filler materials (sand, vermiculite, etc.) required
  • Faster battery loading and unloading process
  • Cleaner operation no loose material to manage or dispose of
  • Reusable without re-filling or re-packing
  • Consistent containment performance across all battery form factors
