On the evening of February 27, 2025, Xiaomi unveiled its two flagship products, the Xiaomi 15 Ultra and the Xiaomi SU7 Ultra, at the 'Dual Ultra' new product launch event. These are the most advanced products Xiaomi has released in its fifteen years of operation. Morion Nanotech's graphene products, known for their cutting-edge technology, provided an excellent thermal management solution for Xiaomi's car and phone 'Dual Ultra' products, helping Xiaomi's home to upgrade its smart life comfort experience.

The Xiaomi 15 Ultra phone features an innovative dual-ring heat dissipation system. The Morion® graphene microcavity thermal film combines heat dissipation and cushioning, boosting the cooling efficiency of Xiaomi's flagship phones and ensuring the device maintains optimal performance with consistent 'cool' output.

       Morion® graphene microcavity thermal film features rich porous structures, excellent thermal conductivity, and compressible rebound properties. It was first innovatively applied in mobile phones in August 2023. The product's thermal conductivity reaches up to 70 W/m·K, surpassing the poor thermal performance of traditional foam materials (＜1 W/m·K). It establishes a thermal channel between the heat source body and the heat dissipation component body, enhancing heat transfer efficiency and effectively improving phone cooling. This fills the gap in the 3C sector for multi-dimensional requirements of thermal materials. With its outstanding thermal performance and material characteristics, this product can be combined with various materials for applications in interface thermal conduction, heat transfer phase change, shielding buffering, and new sensing scenarios.

The Xiaomi SU7 Ultra car seats feature an innovative 'black technology' heating product, the first of its kind in the industry, known as the Morion® pure phase graphene instant temperature control seat heater. This product offers a new instant warmth experience for drivers and passengers. Developed starting in 2022, Morion Nanotech's R&D team, after nearly three years of continuous optimization and iteration, successfully launched the first pure phase graphene heating material in the automotive industry that has passed reliability verification and been applied in vehicles.

The heating material used in the Morion® pure phase graphene instantaneous temperature control seat heating pad is a pure graphene phase heating film, which is composed of 100,000 layers of nanographene stacked in an orderly manner and has excellent properties of high flexibility, high electrical conductivity and high thermal conductivity. When applied to car seats, the pure phase graphene heating pad demonstrates significant bend resistance, rapid heating efficiency, uniform heat distribution, and far-infrared radiation characteristics. The product significantly outperforms traditional convective heating methods and conventional heating materials in overall performance, making it suitable for heat dissipation in car seats and automotive components.

Cooperative exploration
Create new experiences of smart life

The launch of Xiaomi's "Dual Ultra" is not only the answer to Xiaomi's high-end exploration in the past five years, but also the beginning of its advance into the super high-end market. It also marks another major breakthrough for Morion Nanotech in the application field of graphene products.

     Morion Nanotech, starting with the "graphene thermal conductive film" for 3C applications, has gradually expanded its technology to include "high-performance graphene thermal conductive films" for tablets, AR glasses, and base stations, and then to "ultra-flexible graphene thermal conductive films" used in high-end electronic products like foldable smartphones. Now, Morion Nanotech has partnered with Xiaomi to launch the industry's first "pure phase graphene instant temperature control seat heating pad" in the fastest mass-produced car at the Shanghai Auto Show, the Xiaomi SU7 Ultra. Morion Nanotech is continuously driving innovation and application of graphene technology through its comprehensive thermal management capabilities, creating more comfortable and convenient new experiences for users' smart lives. We look forward to collaborating with more partners to explore new paths for the integration of material science and product development.
