Altech Advanced Materials AG: Correction of preliminary annual result as at 31.12.2023 - Seite 3

The joint venture markets its CERENERGY battery and plans to build a 100 MWh production plant on Altech's site in Saxony. The plant will produce CERENERGY battery modules for the grid storage solutions market.
Silumina Anodes
The Altech Group has developed a wet-technology method for coating the anode material of a battery with high-purity aluminum oxide in the nanometer range in a cost-effective and high-quality industrial standard. By coating silicon with high-purity aluminum oxide and adding the material to the usual graphite anode material, the performance of the battery can be increased. With an admixture of 10 %, an increase in performance of more than 30 % has been confirmed in laboratory tests, as silicon has ten times the energy storage capacity of graphite. Until now, however, silicon could not be used in commercial lithium-ion batteries, as silicon particles expand by up to 300% during the battery charging process, leading to partial battery failure. At the same time, lithium ions attach themselves to the anode as a separating layer and are thus deactivated, meaning they are no longer available for the energy flow. Although this also happens with pure graphite anodes, this negative effect is much stronger with silicon-containing anodes and leads to an initial charging loss of up to 50% of the theoretical battery capacity. These side effects have so far negated the potential benefits of adding silicon. The Altech Group has succeeded in coating silicon in the nanometer range and thus largely overcoming the problems described.
