Warum steigt der Preis?
Weil die neuen Aktien fast sicher abgenommen werden? Weil man jetzt noch an günstige zusätzliche Aktien kommt? At market bedeutet 0 bis 5 Prozent Discount. Discount auf was? Auf den Kurs vor / während der Verkündung? Wieso sollte bei dem Book Building der Preis unter 28.5 bleiben, wenn der tatsächliche Preis viel höher ist.
Preis ca nach ke (38.05*55 + 28.5*25) = ca 35 CHF
Sorry, falls ich Käse geschrieben haben sollte.

Stand der Technik im Artikel
Danke für den Artikel. Eigentlich interessant ist das darin verwiesene wissenschaftliche Paper. Ich erlaube mir den relevanten Teil zu zitieren. Ergo sind 3D gedruckte Batterien ein Forschungsthema mit unzähligen zu lösenden Problemen. Anschließend kann es vielleicht mal industrialisiert werden. Das steht im Widerspruch zu dem Zeitplan von BS. Zudem ist mir immer noch nicht klar welcher geistige Wizzzard bei BS diese Probleme mal schnell in den nächsten Monaten lösen soll...
Summary and Outlook
In this review, we have introduced the recent advances in 3D‐printed batteries based on a variety of advanced printing techniques as well as with regard to different electrodes and electrolyte materials. Some significant progress and achievements have been emphasized. However, it should be noted that although much progress has been made in manufacturing 3D‐printed batteries, there are still numerous challenges that must be addressed before they can be widely used commercially. First, there are only a few printable materials, especially active materials, that can be used as inks for 3D printing batteries. As an essential element in 3D printing, inks should have appropriate surface tension, density, and dynamic viscosity. However, most active materials used in 3D‐printed batteries are conventional inorganic materials. To obtain highest electrochemical performance, it is inevitable to develop new electrochemically active materials. In addition, the inks generally contain other additives to tune the rheological properties of the active electrode materials, which may affect the physical properties of the active materials and the electrochemical performance of the batteries. Therefore, greater efforts will be needed to explore more appropriate additive components for printing batteries.
Second, 3D‐printed electrodes are expected to have a larger specific surface area than those electrodes fabricated with traditional methods due to the porous structures introduced in the fabrication process. These porous structures increase the power and energy density of the battery at a cost of mechanical strength. Furthermore, the 3D‐printed structures are produced layer by layer, leading to weakly bonded interfaces between layers. Thus, further research to improve the mechanical properties of 3D‐printed batteries should be done, especially for robustness requirements in certain applications such as flexible and wearable electronics.
Third, although highly ordered pores can be printed by most 3D printing techniques, their sizes are usually at the micrometer scale. Orderly distributed hierarchical pore systems at both micro‐ and nanoscales are particularly important for improving energy storage capacity and rate ability. Additionally, same as other manufacturing methods for electrodes, high‐temperature postprocessing is typically required for 3D printing fabrication of batteries, a time‐consuming and inconvenient procedure that may also sacrifice some electrochemical performance of the battery. In comparison to the traditional manufacturing techniques, current 3D printing also suffers from low efficiency and is challenging to be utilized for low‐cost and large‐scale manufacturing needed in commercial applications. To solve these issues, more advanced 3D printing techniques or a combined technique with higher resolution, higher efficiency, and non‐postprocessing should be developed.
Fourth, water vapor and oxygen in the air have significant effects on the performance of active electrode and electrolyte materials. The chemical reactions triggered upon contact will dramatically reduce the performance and service life as well as safety of batteries. To obtain highly efficient batteries, the preparation and assembly procedures have to be performed in argon‐filled gloveboxes with <0.1 ppm oxygen or water vapor, leading to high cost and greater difficulties. Effective encapsulation for 3D‐printed Li‐ion batteries is also essential to protect them from damage by oxygen/water molecules and other chemicals. Thus, new techniques and materials for printed packaging or encapsulation are also worthy of being developed in the future.
Finally, most of the current research regarding 3D‐printed batteries focuses on the materials of the electrodes and electrolytes. However, despite being important components in batteries, current collectors have rarely been investigated for 3D printing fabrication. Additionally, for fully 3D‐printed batteries, the compatibility of the inks for each component to be printed sequentially and successfully remains a big challenge. Nevertheless, thanks to its ability of printing arbitrary shapes and sizes, 3D printing may be expected to offer great chances for efficiently integrating printed batteries and electronic devices. For example, self‐powered energy systems can be developed by integrating printed batteries and energy harvesters such as solar cells, and triboelectric and piezoelectric nanogenerators to achieve the functions of harvesting and storing human kinetic and environmental mechanical energy. It is expected that with the continuous development of printing techniques and materials, 3D‐printed batteries with long‐term durability, favorable safety, as well as high energy and power densities will eventually be widely used in many fields.

Fragen :
Wieso wird nicht konkret auf die Patente verwiesen (Nummer, geschützte Erfindung)?
Was ist bitte 3D Druck?
Wer ist hier der Batterzellen Mastermind bei dieser Firma?

Magst du etwas verklausuliert den Namen schreiben?
Oder per Boardnachricht?
Ich bin bei Deg**o und zahle 5 CHF plus 0.05 %.
5 CHF flat wäre sehr günstig.

Bitte Trades weiter posten
Das brauch es auch neben fundamentalen Posts, die mehr auf langfristige Trades / Investitionen abzielen.
Persönliches bitte im Mülleimer deponieren oder es sich einfach verkneifen.

QuoteWieso sprichst du über dich? Geht es hier nicht um aryn? Deine Serien-Versager-Empfehlungen?
Mir nachrennen (geiler Trade gestern) lässt dich noch schneller hinterher hecheln.
Aber ich schreibe nichts mehr über meine Trades, brauche solche Neider-Hater-Psychos nicht.

Schöne Argumentation, und welche
Aktie möchtest du shorten? OSRAM oder AMS?

QuoteAMS macht eine teure Wette auf selbstfahrende Autos. Das Angebot für OSRAM liegt nun über 11x dem geschätzten EBITDA von 2020. Dazu kommen noch bessere bindende Konditionen für die Angestellten von OSRAM und gleichtzeitig jedoch ein höherer Bedarf an Synergien. Das sind zwei gegensätzliche Ziele.
Ich überlege mir gerade einen Short Trade *scratch_one-s_head*
