Thermal runaway management system

A pouch for a radio comprising:

• (a) an elongate woven thermoplastic composite material;
• (b) said elongate woven thermoplastic composite material includes a multi-layer construction with an outer layer having a melting point at a lower temperature than a core material sandwiched therein;
• (c) said elongate woven thermoplastic composite material has different axial and transverse thermal conductivities in excess of a ratio of 100;
• (d) said elongate woven thermoplastic composite material arranged in a manner with multiple layers of said elongate woven thermoplastic composite material;
• (e) a first additional layer positioned between at least two of said multiple layers of said elongate woven thermoplastic composite material;
• (f) a second additional insulative layer positioned between at least two of said multiple layers of said elongate woven thermoplastic composite material;
• (g) said elongate woven thermoplastic composite material at least partially enclosed within a UHMWPE fabric material.
