ENPlus Develops Two New Secondary Battery Heat Dissipation Materials Applicable to 'AI Semiconductor'

ENPLUS has succeeded in developing high-performance thermal management materials applicable not only to secondary batteries but also to semiconductors for artificial intelligence (AI). On the 29th, ENPLUS announced that it has developed two new graphite-based thermal management materials. With this development, ENPLUS has secured a more diversified portfolio of thermal management material products.

The two new thermal management materials developed by ENPLUS consist of one product in sheet form and one product in stack form, where multiple layers are vertically stacked. A key feature is the use of graphite as the main material, resulting in high thermal conductivity.

After producing prototypes and conducting evaluations at external specialized analysis institutions, the sheet-type product demonstrated a high thermal conductivity level of 990 watts per meter-kelvin (W/m·K), while the stack product recorded a thermal conductivity of 564 W/m·K. The higher the thermal conductivity, the faster the heat propagation speed, maximizing the cooling effect.

ENPLUS expects the two new thermal management materials to create significant technical synergy with the 'Cell-to-Pack (CTP)' technology, which is attracting attention in the electric vehicle industry. The CTP method is a technology aimed at improving electric vehicle battery efficiency. Due to its structure, it has a high integration density between cells, requiring high-performance thermal management materials to handle heat generation.

ENPLUS also anticipates demand for related products in the semiconductor market. As the computation and processing speeds of AI semiconductor chips such as high-performance GPUs (Graphics Processing Units) and NPUs (Neural Processing Units) become ultra-fast, heat generation increases, necessitating minimization of heat through advanced thermal management materials.

An ENPLUS representative stated, “Based on our deep understanding and know-how of carbon-based materials such as graphene, we have succeeded in developing these new thermal management materials. These products can be expanded and applied not only to existing secondary battery products such as electric vehicles and ESS (Energy Storage Systems) but also to the semiconductor field.”
