I/We Claim:
1. An electrode (100) comprising:
a. an insulation material (101);
b. a current collector (102); and
5 c. an active material layer (103);
wherein the current collector has a first portion and a second portion;
wherein the first portion of the current collector has an alternate coating of
the insulation material (101) on top side (101a) and bottom side (101b) of
the current collector;
10 wherein length of each of the alternate coating of the insulation material is
progressively increasing from one end (102a) to another end (102b) of the
current collector (102); and
wherein the second portion of the current collector has a coating of the
active material layer (103) on top side (103a) and bottom side (103b) of the
15 current collector.
2. The electrode as claimed in claim 1, wherein the first portion and the second
portion of both the top side and bottom side of the current collector (102)
are separated by a distance in a range of 0 to 1 mm.
