content in a range of 4 to 10 %, with respect to the total weight of the
insulation layer.
5. The electrode as claimed in claim 1, wherein the active material is selected
from layered oxides, nickel manganese cobalt (NMC), nickel cobalt
aluminium (NCA), lithium iron phosphate (LFP), lithium manganese iron
phosphate (LMFP), or combinations thereof.
6. The electrode as claimed in claim 1, wherein the active material is in a
weight range of 95 to 98%, with respect to the total weight of the electrodic
30 film.
7. The electrode as claimed in claim 1, wherein the conductive additive is
selected from carbon black, graphene, mesoporous carbon, acetylene black,
activated carbon, super P, carbon nanofiber, vapour grown carbon nanofiber,
carbon nanotube, or combinations thereof.
