Application of low-temperature conductive silver paste in new energy vehicles

Silver (Ag) is a white, glossy metal with a soft texture and good flexibility and ductility. It is also the metal with the best conductivity and thermal conductivity. In most industries, the application of silver is irreplaceable, especially in high-tech industries that require high reliability, high precision, and security. Advanced Institute of TechnologyLow temperature conductive silver pasteWidely used in the automotive electronics industry, especially in chips, in film electronics, conductors, switches, contacts, and fuses.

The luminescent properties of silver indicate its application in renewable energy technologies. Among all metals, silver has the highest conductivity, making it an ideal metal for solar cells and automotive electronic components.

Silver has played a role in the automotive industry for decades. With the development of technology, silver containing components are being applied in more diverse light vehicles, which further illustrates the two key characteristics of silver, namely its unique properties of having the highest thermal and electrical conductivity among any metal, as well as its wide availability. In addition, according to publicly available information, the conductivity and corrosion resistance of silver make its application crucial in electronic products, and new energy electric vehicles are no exception.

Advanced Institute of TechnologyPrediction: New energy vehicles, especially pure electric vehicles, require silver in many component applications, including sintered silver, in film electronics, various chip packaging, silver plated wires, contacts, etc. This is due to silver's excellent conductivity, oxidation resistance, and corrosion resistance. Due to their strong electrical characteristics and additional demand for energy management systems, pure electric vehicles consume approximately 1.6-2.2 times more silver per vehicle than traditional internal combustion engine vehicles. According to the World Silver Association, traditional internal combustion engine vehicles require approximately 0.5-0.9 ounces of silver per vehicle, hybrid vehicles require approximately 0.6-1.1 ounces, and pure electric vehicles require approximately 0.8-1.6 ounces of silver per vehicle.

In fact, all electrical connections in cars use advanced technology's low-temperature conductive silver paste: car manufacturers apply silver to the electrical contacts of electric seats, windows, and other automotive electronic products to increase conductivity. With the global emphasis on new energy, the production and sales of new energy vehicles will show an upward trend year by year.

Taking China as an example, according to the "New Energy Vehicle Industry Development Plan (2021-2035)", it is pointed out that by 2025, the sales volume of new energy vehicles will reach about 20% of the total sales volume of new vehicles. Therefore, in this context, the demand for silver in the automotive industry will further increase.

Low temperature conductive silver paste for flexible electronics in new energy vehicles:

1. Electric vehicle power system

Electric vehicle battery monitoring/heating. Providing the maximum possible range within the given battery weight and cost budget is a key requirement for electric vehicle manufacturers. This requires the power battery to be kept in an efficient working state as much as possible, and a very important influencing factor is temperature. In addition, an increase in temperature (and pressure) may also indicate malfunctions and potential safety issues. Therefore, the printed temperature sensor array may provide battery temperature monitoring, and at the same time, a heater can be printed in the same functional film to help the battery maintain its optimal operating temperature.

2. Electric vehicle cabin

1) Human Machine Interface (HMI). The cockpit human-machine interface (HMI) is a major opportunity for printed/flexible electronics in automotive applications. Printed pressure sensors have been widely used for seat occupancy monitoring and may soon enter vehicle control panels, providing a larger input range than pure capacitive touch sensors and eliminating mechanical switches. In addition, occupancy sensors may evolve into multi-point sensors distributed throughout the entire seat structure to monitor passenger comfort.

2) Printing/flexible in car heating. The existing in car heating mainly relies on heating air conditioning, which is very inefficient and not suitable for electric vehicles. By utilizing printing/flexible electronic technology, heating devices can be embedded in the contact area of the human body for more effective heating. This method can be extended beyond seats and steering wheels, such as armrests and center consoles. In addition, the shape retention of printed electronics allows heating elements to be placed closer to the surface, making heating more efficient and sensitive. Transparent thermal conductive materials can be further applied to the surface of materials such as leather.
