Watu wanaongeza utafutaji wa usalama zaidi, gharama ya chini, mifumo ya betri yenye nguvu zaidi ambayo hupita betri za lithiamu-ioni, kwa hivyo karatasi ya alumini pia imekuwa nyenzo ya kutengeneza betri.
Foil ya alumini inaweza kutumika katika betri katika baadhi ya matukio, hasa kama sehemu muhimu ya muundo wa betri. Karatasi ya alumini hutumiwa kwa kawaida kama mtozaji wa sasa wa aina mbalimbali za betri, 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, uzito mwepesi, and relatively low cost.
Kwa mfano, 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, karatasi ya alumini 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. Nyepesi: 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.
