Advanced Institute of Technology Metal Based Electrode: Innovation and Solution for High Performance Thin Film Electrode

1、 Company Overview and Technical Positioning

Advanced Institute (Shenzhen) Technology Co., Ltd. was established in 2016 and is located in Bao'an District, Shenzhen, Guangdong Province. It is a national high-tech enterprise focusing on shielding materials, insulation materials, thermal conductivity materials, and precious metal coatings. The company has its own registered trademark "Research Platinum" and has production bases in Shenzhen and Dongguan. It has passed ISO9001 quality management system certification and its products comply with GJB 773A aerospace standards and RoHS environmental requirements.

Metal based electrodes are one of the core products of Advanced Institute Technology. The company relies on advanced technologies such as physical vapor deposition (PVD), magnetron sputtering, and vacuum evaporation to achieve high-quality deposition of metal films on various flexible substrates such as PPS (polyphenylene sulfide), PI (polyimide), PET (polyester), etc., and prepares high-performance metal based electrodes that combine conductivity, flexibility, and reliability.

2、 Preparation process of metal based electrodes

The preparation of advanced technology metal based electrodes relies on the nanoscale thin film manufacturing process. Traditional electrode manufacturing is often limited by material thickness and uniformity, while thin film metal electrodes achieve precise control of metal thin films on substrates through advanced technologies such as PVD and magnetron sputtering. This technology can not only control the thickness of the metal film between a few nanometers to several hundred nanometers, but also ensure its extremely high uniformity and density, thereby significantly improving the electrochemical performance and stability of the electrode.

The company has independently built a magnetron sputtering and vacuum evaporation production line, using a roll to roll continuous production process, which can achieve efficient, continuous, and uniform deposition of metal layers on the surface of flexible polymer films. Compared with traditional chemical plating methods, PVD technology has advantages such as environmental protection, good coating uniformity, and strong adhesion. It can achieve uniform deposition of metal atoms on the substrate surface under low temperature conditions.

3、 Main product system

Advanced Institute Technology's metal based electrodes can choose different metal coating systems according to different application requirements:

1. Gold plated electrode (Au)

Gold has extremely high chemical stability, excellent conductivity, and low contact resistance, making it the preferred choice for high-frequency and high reliability applications. Advanced Institute Technology PPS gold-plated film electrodes can work stably in high temperature environments above 200 ℃, with surface resistivity as low as 10 Ω· cm. The company can provide customized PPS gold plating film services with thicknesses ranging from 2 μ m to 125 μ m, meeting diverse needs from ultra-thin high-frequency signal transmission to high wear-resistant connectors. At the 10GHz frequency band, the shielding effectiveness of PPS gold plating film exceeds 60dB, which can meet the requirements of aerospace grade standards.

2. Platinum/gold composite electrode (Pt/Au)

Advanced Institute Technology has developed three types of flexible substrate coating solutions for cutting-edge biomedical applications such as neural probes and brain computer interfaces: silver plating, gold plating, and platinum plating. Through material modification, these solutions break through the performance boundaries of traditional electrodes. The process of electroplating platinum/gold on a gold electrode mainly involves three basic elements: electrolyte, anode (platinum/gold), and cathode (electrode to be gold-plated). The platinum/gold on the anode dissolves in the electrolyte to form metal ions, which obtain electrons on the cathode and are reduced, depositing on the surface of the gold electrode.

3. Copper plated electrode (Cu)

Copper has excellent conductivity and good processability. In the field of lithium batteries, the composite current collector with PPS/Cu/PPS sandwich structure is becoming an important technological route to replace traditional copper foil, which can achieve significant weight reduction and energy density improvement while ensuring conductivity. Advanced Institute Technology has accumulated rich process experience in the field of PPS copper plated film electrodes.

4. Nickel plated electrode (Ni)

The company uses magnetron sputtering technology to prepare PPS nickel plated film electrodes, which can convert metal targets into high-purity thin films by sputtering high-speed charged particles in a vacuum environment. It has the characteristics of high efficiency and environmental protection, and can obtain uniform and dense thin films. PPS nickel plated film electrodes have good wear resistance, corrosion resistance, and electromagnetic shielding performance. The product thickness (2 μ m to 250 μ m optional) and square resistance can be flexibly customized according to actual needs.

4、 Typical application scenarios

The flexible electrochemical electrode developed by Advanced Institute Technology is a type of electrode material and device that can stably perform electrochemical functions under deformation conditions such as bending, folding, stretching, and twisting, breaking through the shortcomings of traditional rigid electrodes that are "hard, brittle, and vulnerable". In addition, the company has developed three types of flexible substrate coating solutions, silver plating, gold plating, and platinum plating, with metal coating technology as the core, providing high-precision solutions for the forefront of neural probes and brain computer interfaces.
