Cilvēki pastiprina drošāka meklējumus, zemākas izmaksas, jaudīgākas akumulatoru sistēmas, kas pārspēj litija jonu akumulatorus, tāpēc alumīnija folija ir kļuvusi arī par materiālu bateriju izgatavošanai.
Dažos gadījumos baterijās var izmantot alumīnija foliju, it īpaši kā akumulatora struktūras neatņemama sastāvdaļa. Alumīnija foliju parasti izmanto kā strāvas savācēju dažāda veida akumulatoriem, 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, viegls svars, and relatively low cost.
Piemēram, 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, alumīnija folija 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. Viegls: 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. Izturība pret koroziju: Aluminum has good corrosion resistance, which is crucial to the long-term stability and life of the battery.
