Economic production of high-performance lithium-ion batteries for electromobility by TRUMPF laser
As India is the fifth biggest car market in the world and has the potential to become one of the top three soon by the year 2030, Indian government has accelerated the electric vehicle transition.
The emerging e-mobility market is creating a rapid adoption of Lasers. The demand for components of electric cars and alternative drives is rising continually. Particularly high-performance components directly involved in the production of batteries, electric motors and power electronics for electromobility are at the center.
They require robust processes that can be quickly scaled from today`s low production volumes to mass production. With Laser technology, one can efficiently and affordably manufacture the key components of electromobility, such as electric drives, power electronics, and batteries. Digitization goes hand in hand to meet the production requirements of the automotive industry.
TRUMPF Lasers offer many benefits in the production of lithium-ion batteries for electromobility, and has now become a significant production tool. The range of laser applications in the electrode, cell, module and pack sectors are immense. TRUMPF lasers are already in use for production of E-vehicles in many countries including India. Applications such as low-resistant contacting of live components, gas-tight sealing of battery cells as well as highly dynamic cutting of electrodes are worth of special mention here. TRUMPF lasers are at the center of many e-mobility solutions. It connects battery cells into modules or packs, it ensures tightness and crash safety when joining battery packs and trays. TRUMPF has therefore developed a solution using a green laser. The green wavelength is absorbed much better by copper. Because the material reaches its melting temperature faster, the welding process starts more quickly and requires less laser power. While the infrared laser operates at 2.6 kilowatts of peak pulse power, the green laser uses 1.4 kilowatts for the same weld seam. This process is more energy efficient and produces significantly less spatters. This means that copper welds are always produced with consistent quality on every type of surface.
The market potential of electric mobility is only just beginning to fully unfold because mobility via electric traction drive means more than just electric cars. Indian transport ministry is thinking of a more innovative solution for electric mobility, they are planning to construct an ‘e-highway’ on the proposed Delhi-Mumbai Expressway. The first strictly battery-powered passenger and car ferries are already in operation, in many parts of the world including India. Local public transport in India is now adopting electric buses. The first fully electric tractor is already quietly plowing furrows through fields in Punjab. Bicycles supported by an electric motor have enjoyed growing popularity for years. Electric scooters are a market wherein millions of units are sold per year, especially in East and Southeast Asia. All these e-vehicles requires batteries, power electronics, and electric motors.
