Higher, faster, further: That is the claim of the automotive industry for new e-car models. In fact, a lot has happened in recent years. From e-cars made in France, which at best managed around 200km, to sedans that now travel 1,000km, the development is great. Nevertheless, the comparison between small cars, sedans or SUVs is limp. Reason enough to take a closer look at what really makes e-cars better, using three listed companies as examples.

    Mercedes-Benz: Greater efficiency thanks to new anode technology

    The Mercedes-Benz Group has long been regarded as an e-car laggard. If you spoke to engineers from Swabia, they were never sparing in their criticism of the e-car pioneers from Tesla or Renault. Between the lines, it was often said that German manufacturers were ultimately better at this than their international competitors. **In the meantime, it seems that this self-confidence is well-founded.

    Mercedes-Benz Group achieves a range of 1,000km with its EQXX prototype. However, the Swabians do not cite the huge surface area that an SUV, for example, offers for a battery as the reason, but the efficiency: unlike other batteries, the version installed in the EQXX only has around 100kwH and also manages more power per unit of weight: 210Wh/kg are significantly more efficient than the 160Wh/kg in the EQS. In total, the battery weighs only 495kg. Mercedes achieves this efficiency thanks to a silicon coating on the anode. Usually, the anode in the battery is coated with graphite. However, silicon can store more lithium ions, which positively affects efficiency.

    Altech Advanced Materials: Plans for high-performance anodes in series production

    Bringing this silicon technology to the road is likely to be the most important challenge for Mercedes-Benz. From prototypes with painstakingly manufactured components, on which the engineers themselves may have had a hand, to series production, there is often still a long way to go. But this is where the German company Altech Advanced Materials could come into play. The Company is currently building a pilot plant for revolutionary anode material. The goal is to coat the anode with aluminum oxide in wafer-thin layers. This aluminum oxide can be enriched with the silicon used by Mercedes-Benz in the prototype, thus offering the increase in efficiency already outlined. Altech CEO Uwe Ahrens is pursuing the goal with his company of manufacturing anodes with silicon content on an industrial scale and at low cost.

    "Investors need to know that the development of our technology is far from over. If we succeed in increasing the silicon content of the anode, power increases of 50 to 100% are also possible. But in the end, it will not be about a battery in an e-car having a range of well over 1,000km. In the end, it is about achieving practical ranges with batteries that are lighter, smaller and therefore much cheaper," says Ahrens, who emphasizes the medium-term significance for automakers: "Our material represents a drop-in technology that could come into use much faster."

    Annual general meeting coming up

    Altech Advanced Materials is already cooperating with SGL Carbon and Spanish silicon manufacturer Ferroglobe. The aim of the technology is to be able to respond flexibly to customer requirements. Such an approach is particularly useful for car manufacturers with different model types: Sometimes the maximum range is decisive, other times, it is cost or other factors. Altech seems to be hitting a nerve with its focus on increasing the silicon content in the anode and doing it all cost-effectively - at least for Mercedes, the technology is a key to the convincing performance data of the EQXX prototype. **On August 23, Altech will hold its Annual General Meeting, which will also vote on capital measures. Once there is clarity here, the market is likely to focus more closely on the technology again.

    Varta: Not doing well at all

    One company that enjoys a good reputation for its technology is Varta. However, this reputation stems primarily from powerful button cells and consumer electronics batteries. With the announced entry into electromobility, the share price surged from more than a year ago, but disillusionment is now setting in. Supply chain problems and semiconductor shortages have indirectly blighted Varta's business recently. Details surrounding e-car technology are also scarce. The stock is currently out of favour in the market.

    Most recently, the Company issued new guidance, and the numbers were not well received. "Management would be advised to respond to market expectations and explain the status quo in e-mobility in more detail," stated in a report.

    The Mercedes-Benz initiative around the EQXX shows that off-the-shelf technology is no longer sufficient for car manufacturers. Breakthrough solutions are needed to win over customers. In addition to the silicon content in the anode, Mercedes-Benz also set new standards in terms of aerodynamics and cooling by airflow. Now the challenge is to mass-produce such engineering cheaply. Companies such as Altech Advanced Materials claim to have appropriate solutions for batteries. If the financing is clarified and the market as a whole cooperates, there may be potential here.

    The stock market has been celebrating a significant advancement in productivity on this planet for months: the replacement of human labor with learning machines. What James Cameron envisioned in the 1980s with his movie "Terminator" has now become a reality. The era of job destruction is now underway around the globe. Standard services or control processes, such as those in call or quality centers, are particularly affected. The friendly voice on the phone that takes care of your problem could already be an AI-generated response. You may only notice it when asking questions that deviate from the norm. Economists predict a leap in productivity of over 20% in the next 10 years. However, it is doubtful whether high-tech stocks on the NASDAQ will continue to perform as erratically as they have recently. It may be time to consult a stock market AI. We have a few ideas on this matter.

    In the dynamic stock market environment, companies that invest in innovative technologies and specialization at an early stage stand out with above-average success. Amazon, once founded as a small online bookstore in a garage, is a shining example of this strategy. Through clever diversification and pioneering work in new technology fields, such as cloud computing with Amazon Web Services, Amazon has developed into one of the most valuable corporations. For investors, Amazon's rise underlines the golden opportunities: those with the foresight to invest in future-oriented companies can achieve above-average profits. We have selected three companies that aim to follow this path or have partially already done so.

    The stock market year 2024 is entering its second quarter and has again started with record highs. The DAX reached new all-time highs of 18,571 points, while the Dow Jones broke through the 40,000-point barrier for the first time in its history. Despite the boom in the most important stock market barometers, many sectors are still in a deep sleep and are waiting to be kissed awake. The recent weeks have shown, with cannabis stocks as an example, how quickly a rebound can be initiated.
