Tib neeg tab tom nrhiav kev nyab xeeb dua, tus nqi qis dua, Cov roj teeb muaj zog ntau dua uas ua tau zoo dua lithium-ion roj teeb, yog li cov ntawv txhuas txhuas kuj tau los ua cov khoom siv los ua cov roj teeb.
Aluminium ntawv ci tuaj yeem siv rau hauv cov roj teeb hauv qee kis, tshwj xeeb tshaj yog ib feem tseem ceeb ntawm cov qauv roj teeb. Aluminium foil feem ntau yog siv los ua cov khoom siv tam sim no rau ntau hom roj teeb, 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, lub teeb nyhav, and relatively low cost.
Piv txwv li, 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, aluminium ntawv ci 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. Lub teeb: 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 kuj: Aluminum has good corrosion resistance, which is crucial to the long-term stability and life of the battery.
