TEG-Blanket

Overview

TEG-Blanket is a flexible, reusable fireproof blanket built on ARBOK's TEG / graphene-like material, designed to smother and contain electric-vehicle lithium-ion battery fires. EV battery fires burn extremely hot, are hard to extinguish with water, and reignite (thermal runaway); a high-temperature, low-conductivity blanket isolates the fire, contains it, and buys time for responders. It is a different application of the TEG family from GCM (rocket/hypersonic skin) and LB HEAT (industrial insulation).

Applications

Containment of EV and battery-pack fires; deployment by fire/emergency services; safety cover at parking garages, charging stations, ferries, and vehicle transport. Potentially scalable to battery-storage sites.

Users: fire services, EV operators, parking/charging and transport operators.

Operating Principle

The TEG / graphene-like blanket is deployed over a burning or smoking EV, cutting oxygen supply and providing a high-temperature barrier that contains heat, flames, and ejecta while the battery burns out, limiting spread and reignition. Flexible and reusable, unlike single-use suppressant approaches.

Limitations: blanket-specific performance data are not in the base — properties below are inferred from the TEG material family and must be measured for this product.

Key Parameters

Material basis: TEG / graphene-like (same family as LB HEAT insulation — high-temperature tolerance, low thermal conductivity, non-combustible, lightweight, flexible). Blanket-specific parameters — size/coverage, areal weight, max contained temperature, number of reuses, containment time — are not specified in the source and must be defined and tested.

Note: no blanket-specific numbers exist in the base; do not cite TEG bulk-material maxima as blanket performance without measurement.

Architecture and Components

Flexible TEG / graphene-like fabric/sheet (single or multilayer); reinforced edges/handles for deployment; optional outer protective layer. Form factor sized to cover a passenger EV (to be specified).

Advantages

Technical: high-temperature tolerance and low conductivity of the TEG family; flexible and reusable; lightweight vs heavy silica/fiberglass alternatives. Economic: reusable (vs single-use blankets/suppressants); leverages ARBOK TEG production. Environmental: no rare-earths, recyclable material family, no chemical suppressant runoff.

Integrations

Built on the ARBOK TEG material family (LB HEAT, Modified Glassy Carbon (GCM), AEROGRAPH (Graphene AeroGel)); fits fire-service equipment and EV-charging/parking safety protocols.

Deployment & Operation

Steps: store at charging/parking site or on response vehicle → deploy over burning EV → contain until burnout → inspect/reuse. Remaining: define blanket specifications and test containment performance against real EV battery fires.

TRL

TRL 3 (confirmed by Michael). Experimental proof-of-concept: TEG material thermal capability is established (cf. LB HEAT), but a TEG-based EV fire blanket has not been specified or tested as a product — performance parameters remain to be defined.

TRL scale:

• TRL 1 — basic principles observed
• TRL 2 — technology concept formulated
• TRL 3 — experimental proof-of-concept ← TEG-Blanket
• TRL 4 — validated in lab
• TRL 5 — validated in relevant environment
• TRL 6 — demonstrated in relevant environment
• TRL 7 — prototype in operational environment
• TRL 8 — system complete and qualified
• TRL 9 — proven in operational environment

Market Potential

EV adoption is making battery fires a fast-growing safety problem for fire services, parking garages, ferries, and car transport — current fire blankets are heavy single-use silica/fiberglass. A lighter, reusable, high-temperature TEG blanket — once specified and validated — addresses emergency-services and EV-infrastructure safety markets.

Typical Project Economics

Value from reusability (vs single-use blankets/suppressants) and reduced fire-spread damage. No cost/price data in source — flagged as missing; economics indicative until the product is specified.

Risk Factors

No blanket-specific performance data exist — containment temperature, reuse count, and coverage must be measured, not assumed from bulk TEG properties. EV fires reignite and emit toxic gases; a blanket contains but does not fully extinguish. Certification for fire-service use required. Competes with established silica fire blankets. Product specification is the first gate.
