Ľudia zintenzívňujú hľadanie bezpečnejších, nižšie náklady, výkonnejšie batériové systémy, ktoré prekonávajú lítium-iónové batérie, takže hliníková fólia sa stala aj materiálom na výrobu batérií.
V niektorých prípadoch je možné použiť hliníkovú fóliu, najmä ako integrálna súčasť štruktúry batérie. Hliníková fólia sa bežne používa ako zberač prúdu pre rôzne typy batérií, 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, nízka hmotnosť, and relatively low cost.
Napríklad, 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, hliníková fólia 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. Ľahká: 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. Corrosion resistance: Aluminum has good corrosion resistance, which is crucial to the long-term stability and life of the battery.
