Product Applications
1.Used as the positive electrode collector of lithium batteries.
Advantage:
i.Improving safety
Composite aluminium film contains a layer of polymer which has a much lower melting point. When short-circuit happens, the polymer layer acts like a fuse and melts due to heating. Thereafter, the short-circuit breaks and heals, preventing the battery from explosion due to heat accumulation within it.
ii.High energy density
The polymer in the composite aluminium film is very much lighter than aluminium, so the energy per unit mass of the battery is higher.
iii.Longer life time
The polymer layer is more durable than aluminium under frequent expansion and shrinking during charging and discharging, extending the life time of battery.
