Wilco Inc., which is developing materials that delay thermal runaway of electric vehicle battery packs, succeeded in attracting investment from Hansaeyes24 Partners on the 28th.

Recently, Wilco succeeded in developing a 1 mm thick composite sheet with excellent heat blocking performance and withstanding 60 minutes or more in flames of 1200°C or higher, an environment for thermal runaway electric vehicle battery packs. This product is a composite sheet with excellent heat blocking performance in which the temperature of the opposite side of the surface to which the flame is applied is maintained below 280°C in a torch evaluation of about 1200°C or higher.

The thermal runaway of EV batteries is caused by overcharging or external impacts of battery cells, and where a unit module has no materials to prevent thermal runaway, it would lead to battery pack fire or explosion in a short period of time.

When applying the sheet for the top cover of the battery pack developed by Wilco, it can greatly help drivers evacuate and extinguish fires by delaying the fire that occurred within a minute by more than 20 minutes even when a thermal runaway occurs. In addition, Wilco will develop a Celt-to-Cell thermal runaway delay material that efficiently manages heat between battery cells and cells while at the same time has a thermal runaway delay function and will be applied and evaluated next year.

Wilco Inc., which has attracted this investment, plans to prepare for mass production of composite sheets for battery top cover and Celt-to-Cell thermal runaway delay materials and diversify products based on this investment.

Wilco attracted seed investment from POSTECH Holdings in the early days of its founding and has since advanced flame retardancy, heat dissipation, and low dielectric technologies.

"Wilco Corporation is proving to be ahead of other competitors by having differentiated technology in non-combustible/insulating materials and high-performance heat dissipation products through new technology attempts as well as thermal runaway delay materials, and the technologies Wilco is developing further are also expected to continue to grow in the areas of mobility, satellites, and communications in the future," said Nam Sang-il, head of Han Se-yes 24 Partners, who led the investment.

Wilco Park Sang-won, CEO of Wilco, said, "Currently, Wilco's thermal runaway delay sheet has passed the final reliability evaluation from electric vehicle manufacturers and will be applied to the mass production model in 24 years."
