MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631059257 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on May 9, for '4d-printed, thermally morphing multi-material lattice for self-optimizing ev battery thermal runaway protection and structural reinforcement.'
Inventor(s) include Adrija Mukhopadhyay; Kuntal Das; Dr. Sumit Chabri; Arghya Gupta; and Akhtarujjaman Sarkar.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a 4D-printed, thermally morphing multi-material lattice for autonomous EV battery protection and structural reinforcement. The lattice utilizes shape-memory polymers and liquid crystal elastomers to undergo programmed, temperature-triggered shape changes, such as collapsing to create an insulating air gap or expanding to mechanically disconnect a failing cell. Integrated coolant microchannels passively widen in response to heat to redirect flow to hot zones. A rigid structural backbone ensures the lattice maintains pack stiffness and crashworthiness. The system operates without external sensors or power, triggered solely by the heat of a failing battery cell, thereby preventing thermal runaway propagation while reducing total pack weight and complexity."
