Lámina de batería H18

junio 24, 2022

La estructura básica de una batería de litio incluye un electrodo positivo., un electrodo negativo, un electrolito, y un separador. Las baterías de litio tienen cuatro materiales clave: un papel de aluminio, una lámina de cobre, un separador en el medio, y el resto son electrolitos.

 

El papel de aluminio de la batería se refiere al papel de aluminio utilizado para el material del electrodo positivo de la batería de iones de litio., or the aluminum foil for lithium battery current collector, which belongs to the finishing product in the aluminum foil product series. En el presente, the commonly used alloy components of hoja de batería h18 mainstream products are pure aluminum 1000 serie, 1060, 1070, 1080 y 1235, thickness 0.010~0.020mm, temper is H18. Adicionalmente, there are many varieties of aluminum foil products used in other parts of lithium batteries, such as aluminum-plastic film for battery soft packs, tabs, and modified carbon-coated foils, electro-erosion foils and other products. Por lo tanto, aluminum foil plays a crucial role in the development of new energy battery.

Aluminum h18 battery foil for lithium batteries has high requirements on alloy composition, flatness, espesor, dyne value, cleanliness, poros, and performance. En el presente, domestic aluminum foil products used in the field of low-end batteries are gradually becoming saturated, while aluminum foil products that meet high-end power batteries are in short supply. The application characteristics of lithium batteries and the high quality indicators of papel de aluminio de la batería require the aluminum processing industry to take corresponding measures to produce battery aluminum foil products with excellent quality and customer satisfaction.

 

Advantages of aluminum hoja de batería h18 in the field of lithium-ion batteries are:

1, Extend the service life of lithium-ion batteries, because the special aluminum battery foil has better physical properties, which significantly improves the cycle function of lithium-ion batteries.

2, To improve the consistency of lithium-ion batteries, the use of special battery aluminum foil can not only reduce internal resistance, but also improve the consistency of internal resistance.

3, Improve the rate discharge function of the battery. After the h18 aluminum foil is selected, the rate function of the lithium-ion battery is significantly improved, especially in the case of a large rate (greater than 3C), the rate discharge capacity is more than 15%, perhaps at the same rate. In cases, battery aluminum foils can travel the energy density of lithium-ion batteries.
