Whitepaper: Leak Detection for Electric Vehicle Battery Production

  Electric vehicles are a decisive factor in reducing CO2 emissions in road traffic. They store the energy required for propulsion in batteries and an electric motor converts it into motion. If the batteries are charged with electricity from renewable energy sources, they even have a completely CO2-free energy balance. Today, lithium-ion batteries are used almost exclusively as accumulators. Vacuum technology is indispensable for their production. This white paper shows how test gas leak detection ensures quality The proper functioning, quality and safety of lithium-ion batteries, which are used as accumulators in electric vehicles, depends on their integrity and impermeability to external influences such as moisture ingress. For this reason, leak detection systems are used in battery production to check the batteries. Pfeiffer Vacuum supplies the necessary vacuum solutions from a single source.

Oil diffusion vacuum pump

The oil diffusion pump is operated with an oil of low vapor pressure. A high speed jet of the Oil is generated by boiling the Oil and directing the vapor through a jet assembly. Note that the oil is gaseous when entering the nozzles. Within the nozzles, the flow changes from laminar, to supersonic and molecular. Often several jets are used in series to enhance the pumping action. The outside of the diffusion pump is cooled using either air flow or a water line. As the vapor jet hits the outer cooled shell of the diffusion pump, the working fluid condenses and is recovered and directed back to the boiler. The pumped gases continue flowing to the base of the pump at increased pressure, flowing out through the diffusion pump outlet, where they are compressed to ambient pressure by the secondary mechanical forepump and exhausted. Diffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump is typically used to maintain an outlet pressure around 0.1 mbar. Diffusion pumps have no moving parts and as a result are quite durable and reliable. They can function over pressure ranges of 10−10 to 10−2 mbar. They are driven only by convection and thus have a very low energy efficiency and low cost per unit pumping speed when compared with other types of pump used in the same vacuum range. One major disadvantage of diffusion pumps is the tendency to backstream oil into the chamber being evacuated. This oil can contaminate surfaces inside the chamber or upon contact with hot filaments or electrical discharges may result in carbonaceous or siliceous deposits. Generally cold traps and baffles are utilized between the chamber and the diffusion pump to minimize backstreaming, although this results in some loss of pumping ability. The oil of a diffusion pump cannot be exposed to the atmosphere when hot. If this occurs, the oil will burn and has to be replaced .

Leybold launches Vacuum Calculation and Simulation Tools

  Pump Finder and Leycalc as a calculation tool are web-based tools, users can select and build their vacuum solutions online. The Pump Finder is designed to navigate vacuum users step-by-step to find the ideal pump for their application. Throughout the selection tool, pumps can be refined by entering values for chamber size, target pressure and pipe dimensions. There are two calculation options for modelling different vacuum applications: process flow and vacuum chamber pump down. A process gas flow is a continuous gas flow where the constant pressure is conveyed. A vacuum chamber pump down is an application where the chamber is pumped/evacuated to a specific target pressure. The result is a selection of vacuum pumps that meet the customer's requirements.

Leycalc can be used for detailed engineering of vacuum systems using the same powerful algorithms as Leybold’s application experts. The tool allows customers to calculate their vacuum systems fully independently and for complex scenarios, the experts offer their full support. "Previously, we had to adjust parameters such as chamber size, process gases, cycle times, pipe length and pressure values during the initial contact with the customer. With the help of the simulation software, the user can independently calculate configurations and get an initial idea of the vacuum performance," explains Dr. Tom Kammermeier, Global Application Manager, Industrial Vacuum. "In the past, there were often lengthy dialogues about such details," says Kammermeier. “Now users can perform their calculations independently – with the result that the entire process leads to a more targeted and faster selection of the right solutions for the application. We expect Leycalc to improve the contact quality with our customers." https://calc.leybold.com/en/lp Read the full article

Brief Introduction of Metallization Ceramics

Brief Introduction of Metallization Ceramics  Advanced ceramics are widely used in electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Advanced ceramics have good thermal stability (i.e., a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard and have excellent dimensional stability.

As a result, the list of applications for advanced ceramics is including aerospace engine blades, rings and valve components, industrial pump bearings, cutting tools and die parts, medical instruments, and wide uses in the electronics industry as a substrate and in specialized vacuum components. Metallization ceramics is a famous coating technology in advanced ceramics. They are commonly used in many applications, for example, in power electronics components placed under extreme load, electrical drive engineering, and electrical engineering as well as in electronic components for computer technology.

Key Features Standard Moly-Manganese coatings of .001”+/-.0005” offers a uniform coat and optimum peel strength Standard Nickel plating thickness of .0001”/.0004” creates an ideal surface for vacuum-tight braze seals Key Benefits Superior bare ceramic and metallization quality Vertically integrated ceramic processing with traceability from the bare ceramic powder through metallization and Nickel plating Application engineering support Specialization in prototype to medium volume with the ability to seamlessly upscale to high volume production if required.
