High purity alumina should significantly improve e-car batteries-alumina

The German company Altech Advanced material works on a technology that should make electric car batteries more efficient and more durable: thanks to a nano coating of the battery anode with highpurity aluminum oxide, the initial load loss of approx. 8 percent avoided and the battery life is extended by up to 30 percent. However, these findings are still theoretical nature.

In order to bring the technology into production, the company has already received a cooperation agreement with the battery manufacturer SGL Carbon. Previously, however, another test facility must be built to gain further insights into the realizability of the project. For this, Altech Advanced Materials are currently collecting a capital increase on the stock market the financial resources – 6.5 million euros wants to redeem the company. Altech board Uwe Ahrens talked to the centralized magazine about the peculiarities of the technology and the other perspectives of his company.

The first results of a feasibility study to improve lithium-ion batteries over a coating of the anode material with high purity alumina, so-called HPA, had been “very promising”, says Ahrens. With the fresh capital wool altch soon starting to “produce first smaller quantities in a test system, provide the different battery manufacturers to test purposes and thus to use in batteries”. If the expected special features of the material are confirmed at a pre-industrial level, “we will then build a production work in a second step to supply the European market of battery manufacturers,” Announces Ahrens.

With the most exciting, the reduction of the essential cycle capacity loss would be due to relatively little effort, the capacity of a battery would increase by just over 8 percent. With a 60 kWh compactor with currently common technology, a good 5 kWh could be gained. Or otherwise expressed: the range of such an e-car would rise by a good 25 to 30 kilometers. “So there is more power available without making a serious and thus expensive change on the construction of a battery,” explains Ahrens’s advantages of the new technology. Make the coating “as so-called drop-in technology very interesting for the industry”.

Altech wants to have already developed a process and a procedure, “How to make an industrial level cheap and fast the sheath of the particles with HPA, from which the anode consists,”. Ahrens assumes that the first batches of the new anode material “produce quickly”. “Then we are not in bulk production, but a belonging step further”. The Altch board did not want to announce exact times.

“Massive increases in energy density and thus the range”

A location for its first test production as well as the planned plant with a plant capacity of 10.000 tonnes per year For the coating of graphite in anode quality, the company has already found, in the northeastern Saxony, in the industrial park black pump. The location was well developed by the existing infrastructure such as network stream and natural gas, rail and road and is extremely favorable for a project of this kind. Black pump is 120 km from Berlin and 78 km from Dresden. “In this region, just a lot of battery technology happens,” says Ahrens: “Just think of the Giga factory of Tesla, which is not far away”.

An anode nano coating with highpurity alumina would also be well with silicon, which could enable as an anode material “massive increases in energy density and thus the range”. “But silicon expands through the energy supply and the grid of the compounds becomes unstable,” as Ahrens describes one of the challenges of this technology. Here, “a coating of the composite material of graphite and silicon with HPA manifest a remedy,” says the Altech boss.

Ahrens expects future for the electromobile, “that E-cars have become significantly cheaper, have a range of well over 1000 km, which lies continuously with a few minutes and the risk of overheating of the batteries belonging to the past”. A share should also have the use of HPA.

  1. That’s why in advance. It should be noted: The company is “only” 25% of the Excluisen technology user only involved in the European Union. And we are talking about any existing production. It’s only about a “potential” production facility. And the addressed patents must “not yet be registered”. Mr. Ahrens is therefore in the beginning for a microcap. There are no revenues yet. No patents yet. So a highly risky company.

    Or in other words – it could be “foam rackets” – for me for the time being uninteresting.

  2. High purity aluminum oxide on the anode target Improve electric car batteries significantly. Whether it does that will have to point.
