A sandwich composite structure of high-conductivity CNT-TCF substrate + electrodeposited LDH (Layered Double Hydroxide) energy storage layer + transparent conductive encapsulation layer is adopted, which achieves a breakthrough integration of three functions: transparent conductivity, supercapacitor energy storage, and high-efficiency Joule heating.

The CNT-TCF provides a stable conductive path and flexible support. The LDH layer, with precisely controlled thickness (5–10 μm) via electrodeposition, features both high energy density and optical transparency. The transparent encapsulation layer ensures structural stability. Together, they satisfy the multifunctional requirements of automotive and home appliance applications.

It perfectly matches automotive transparent components such as Tesla’s panoramic glass roof and Li L-series panoramic sunroofs. Powered by 12V low voltage, it can reach 35°C within 120 seconds for rapid anti-fogging and de-icing, solving the problem of poor visibility during winter driving.

It also suits home appliances including Hisense transparent refrigerators and Samsung transparent OLED TVs. The energy storage layer can store standby power and supply core components (control panels, sensors, etc.) in emergencies, maintaining basic functions.

It exhibits outstanding mechanical flexibility: after 1000 cycles of 180° repeated bending, the capacitance retention rate remains at 97% and the resistance change rate is < 3%, making it suitable for curved automotive roofs and irregular transparent home appliance panels.
The electrochemically optimized LDH energy storage layer shows a capacitance decay of < 5% after 10,000 charge-discharge cycles, meeting the service life requirement of over 10 years for automotive and home appliance applications.

Visible light transmittance ≥ 85%, haze ≤ 0.5%, without affecting daylighting of automotive roofs or transparent display effects of home appliances.
Areal capacitance reaches 1.57 mF/cm², with energy density 40% higher than traditional transparent supercapacitors. Joule heating power density is 0.8 W/cm², balancing energy storage efficiency and heating speed. Powered by 12V low voltage, it is safe and hazard-free.

The LDH energy storage layer uses NiCo-LDH material, forming an ordered layered structure on the CNT-TCF substrate via electrodeposition. The interlayer spacing is controlled at 0.76 nm, enabling fast ion transport (ion diffusion coefficient: 1.2×10⁻⁹ cm²/s) while maintaining high transparency.

The nitric acid-doped CNT-TCF substrate has a sheet resistance ≤ 15 Ω/sq, providing an efficient conductive path for energy storage and heating.

Based on the uniform conductivity of the CNT network, a uniformly heated surface is formed upon energization with low thermal temperature difference. The electricity-to-heat conversion efficiency reaches 92% at 12V, enabling rapid heating while avoiding local overheating.

Integrated with an intelligent temperature control chip, the temperature can be precisely regulated within 5–40°C for various scenarios.

Customized transparent conductive adhesive is used for interlayer bonding and edge sealing. The adhesive has transmittance ≥ 90% and 180° peel strength ≥ 0.6 N/mm, ensuring interlayer electrical continuity and excellent waterproof and anti-corrosion properties, adapting to high-temperature and high-humidity automotive environments and long-term home appliance usage.
