Οι άνθρωποι εντείνουν την αναζήτηση για πιο ασφαλή, χαμηλότερο κόστος, πιο ισχυρά συστήματα μπαταριών που ξεπερνούν τις μπαταρίες ιόντων λιθίου, έτσι και το αλουμινόχαρτο έχει γίνει υλικό για την κατασκευή μπαταριών.
Το φύλλο αλουμινίου μπορεί να χρησιμοποιηθεί σε μπαταρίες σε ορισμένες περιπτώσεις, ειδικά ως αναπόσπαστο μέρος της δομής της μπαταρίας. Το φύλλο αλουμινίου χρησιμοποιείται συνήθως ως συλλέκτης ρεύματος για διάφορους τύπους μπαταριών, including lithium-ion and other electrochemical cells.
In batteries, current collectors are critical components that help electrons flow between the battery’s active materials and the external circuitry. Aluminum foil was chosen as the current collector because of its good electrical conductivity, μικρό βάρος, and relatively low cost.
Για παράδειγμα, in lithium-ion batteries, aluminum foil is commonly used as the positive electrode current collector. The cathode is one of the key components of the battery where electrochemical reactions take place during charge and discharge cycles. Aluminum foil helps collect electrons generated during these reactions and allows them to flow through an external circuit.
As a material for making batteries, αλουμινόχαρτο has many advantages
1. Good electrical conductivity: Aluminum is an excellent electrical conductor, which can effectively transfer electrons to make it play a role in the charging and discharging process in the battery.
2. Πυγμάχος ελαφρού βάρους: Aluminum foil is very light, which helps to reduce the overall weight of the battery, especially for mobile devices, electric vehicles and other applications that require light loads.
3. Relatively low cost: Aluminum foil is a relatively cheap material, which helps to reduce the cost during the manufacturing process of the battery.
4. Plasticity and ease of processing: Aluminum foil can be easily processed into various shapes to meet the design requirements of different types of batteries.
5. Αντοχή στη διάβρωση: Aluminum has good corrosion resistance, which is crucial to the long-term stability and life of the battery.
