Lead Tab
Introduction to Lead Tab
Lead Tab is a component used in
pouch-type batteries and
used in electric vehicle battery cells.
What is Lead Tab?
Lead Tab is the positive and negative terminals of
a pouch-type battery.
As a key component of pouch-type
battery cells, it is a indispensable material that determines
stable power supply and continuous battery life.

Our Technology
Description of Lead tab production process
Lead Tab Production Process
Our differentiated lead tab manufacturing technology
introduces and operates state-of-the-art technology for
excellent quality and customer satisfaction.
Our technology is divided into 4 processes(Supply Unit,
Fusion Unit, Vision Unit, Load Unit) for attaching the film,
which is the core technology for lead tab production.
A supply unit that sets raw materials to conditions for
fusion of metal and film, which are the core technologies
for lead tab manufacturing.
A fusion Unit does not allow even a small defect of 0.1㎛ to
prevent leakage of the electrolyte of the pouch type
secondary battery.
A Vision part identifies product defects with a
high-performance camera, and a loading part that loads
the finished products into the tray pocket.
Our factory produce world-class lead tabs
through
completed establishment of an automated production
process system
What’s Differentiation of
our fusion technology?
Lead tabs used in pouch-type battery cells must withstand
harsh conditions. A small gap which occurred between the
film and metal leads to electrolyte leakage and a blaze.
In order to protect everyone's safety, our fusion welding
process introduces differentiated technology.
Key of lead tab manufacturing is strong bonding between
raw materials and film. To ensure stable supply of film and
prevent human error, We adopt a self-developed sensor
in each section
of Film passing slot and monitoring the
‘Front and Back classification’ of film in real time.
In addition, in order to prevent fusion defects, we do not
allow even a small fusion defect of 0.1㎛ by ultra-precision
setting with the development of a special mold containing
our know-how.
Our fusion technology is a collection of various equipment,
but it is designed with everyone's safety as the top priority.
‘Interlock’ was introduced in all areas to prevent accidents
that may occur.
Safety of employees is ensured by installing
a 'Safety Cover' to prevent constriction and stab wounds
caused by automated facilities.
The world's best technology and various systems for
everyone's safety are Soulbrain SLD's uniquely differentiated
technologies that have been selected by global companies.
