Problem
Thermal runaway propagation (TRP) in lithium‑ion battery packs can trigger rapid, uncontrolled fires that jeopardize vehicle safety, aircraft reliability, and the integrity of stationary storage systems. Existing battery designs often lack effective measures to absorb the intense heat and prevent chain reactions between cells.
Solution
Proteba supplies custom‑engineered thermal barrier and potting materials that absorb large amounts of heat during a cell failure, creating a “Zero‑TP” effect that stops propagation to neighboring cells. The company tailors barrier geometry and material composition to the specific cell format—prismatic, pouch, or cylindrical—and to the mechanical constraints of each module. In‑house abuse testing facilities, including nail, heater, and over‑charge rigs, validate the performance of each solution under realistic failure scenarios. Proteba’s engineering team works with customers to integrate these barriers and potting compounds into their module designs, using a test‑driven development approach that accelerates validation and reduces costly redesigns. The resulting battery packs meet higher safety standards for automotive, aerospace, power‑tool, home‑storage, and grid‑scale applications.
Target Audience
Proteba serves battery developers and system integrators in the automotive, aerospace, power‑tool, residential storage, and utility‑scale energy sectors that require certified safety solutions for lithium‑ion packs.
Features
- High‑enthalpy, endothermic thermal barriers designed for prism and pouch modules that absorb excess heat and maintain low temperatures on adjacent cells
- Side‑potting formulations for round‑cell modules, optimized for density, rheology, and mechanical strength
- Top‑potting (over‑potting) material compatible with all cell formats, forming a protective film over vulnerable areas to vent hot gases and particles
- Mechanical design customization to ensure barrier integrity under cell expansion, pressure, and vibration loads
- In‑house abuse‑test suite (nail, heater, over‑charge, vibration) with post‑mortem analysis to verify barrier effectiveness
- Rapid prototyping and rapid‑iteration workflow supported by CNC machining and 3D printing capabilities
- Collaborative material development with chemical‑industry partners to fine‑tune formulation properties such as thermal conductivity and curing behavior
