Ang aluminyo foil ay gumaganap ng isang mahalagang papel sa pagbuo ng mga baterya ng lithium-ion. Mayroong maraming mga modelo sa 1000-8000 serye ng mga haluang metal na maaaring magamit sa paggawa ng baterya.
Purong aluminum foil: Ang purong aluminum foil na karaniwang ginagamit sa mga baterya ng lithium ay kinabibilangan ng iba't ibang grado ng haluang metal tulad ng 1060, 1050, 1145, at 1235. Ang mga foil na ito ay karaniwang nasa iba't ibang estado tulad ng O, H14, H18, H24, H22.
Lalo na ang alloy 1145. The alloy is known for its high electrical conductivity, low impurity content and good formability, making it suitable for use as a current collector in batteries.
Other aluminum alloys that can be used in battery applications include the 3xxx series of alloys, tulad ng 3003 at 3104, which offer a balance of strength and formability. Bukod pa rito, some battery manufacturers may use 8xxx series alloys to meet specific performance requirements.
Aluminum-silicon alloy foil: Aluminum foil containing silicon alloy is a promising anode material for next-generation lithium-ion batteries. They offer a balance between low cost, environmental friendliness and high performance.
Researchers found that aluminum foil anodes exhibit higher performance and stability in solid-state batteries compared to traditional lithium-ion batteries. Overall, the selection of aluminum alloys for battery applications depends on factors such as conductivity, formability, strength and cost considerations.
