EV

An electric vehicle consists of 3 major parts: a motor, a battery, and a reducer.
Glolinx providing parts and materials needed for traction motors and batteries for electric vehicles.

Heterogeneous Material Bonding Technology

Busbar Connector
A busbar connector assembly that connects electric vehicle transaction motors and inverters. This is an injection-molded product using heterogeneous material bonding technology to bond metal busbars, which went through a special surface treatment using the etching method for thermoplastic plastic resins and metal materials.
The conventional busbar connecter assemblies made by other companies have been manufactured by bonding thermoplastic plastic resins and metal busbars with a silicone adhesive, but they used to have serious safety problems, such as poor airtightness and vulnerability to heat, resulting in current leakage and risks of fire accidents when leaking current meets the volatile working fluid in the motor.
Glolinx is doing its best to solve such problems with this product, and manufacturing a safer product with complete airtightness, and rather than using the molecular bonding of silicone adhesives, it uses the above-mentioned heterogeneous material bonding technology.
Automotive Cooling System
In the case of electric vehicles, it is a general trend to use not only secondary battery modules or module-integrated packs but also highly energy enriched and highly integrated modules or packs, to increase the mileage for a single charge. Accordingly, we cannot keep up with the current trend using the conventional cooling method, air-cooling, so we are in a transition period from this to using water cooling. We can now respond to all kinds of customer needs including cooling unit related thermal analysis, cooling simulation, cooling channel design, life-size product validation through mock-up and mold manufacturing, and mass production. In partnership with leading domestic and overseas partners, we have competitive competencies in everything from basic thermal analysis to mass production of cooling units.

Realize the bonding strength up to the material destruction level

The metal and resin that have been drilled onto the surface with special technology are joined by injection molding using an anchor effect.

When observing the joint cross section using carbon mapping, it was seen that the resin (orange) infiltrated into the metal (black).

In the strength test (compression shear test), according to ISO19095, this heterogeneous material bonding technology shows how the destruction of the base material demonstrates high bonding strength.
In addition, this heterogeneous material bonding technology allows for a shear bonding strength of 20 MPa or more when conducting thermal shock tests, heat resistance tests, and constant temperature and humidity tests under severe conditions, proving the airtightness between the metal and resin bonding interface.

Other EV materials

LEAD TAB
We are now developing surface treatment process technology to improve the bonding strength between lead tabs and seal films.
Using the surface treatment technology of Japan's Mitsui Chemicals, the surface of the metal material for a lead tab is processed to maintain a more proper bonding state with a seal film in order to improve the long-term reliability of the product.
GM80
It is an aluminum rolled material containing 8% or more magnesium.
Magnesium is a very light metal, having a specific gravity of two-thirds that of aluminum. When a large amount of magnesium is added to an aluminum alloy, the strength increases to protect the durability of a vehicle, and the weight of the vehicle body can be significantly reduced to increase fuel efficiency.
In addition, since the strength of the product is comparable to that of duralumin, even without heat treatment, it can be used not only as an automobile material with high-strength properties but also as an alternative to various apparatuses, electric devices, and facilities due to its low price.
Currently, Glolinx is leading the non-ferrous material development business by successfully establishing stable alloy composition and complex process technology for breakthrough quality and price, in cooperation with many companies around the world.
LiOH
LiOH, along with Li2CO3, is an essential material for lithium secondary batteries.
Li2CO3 is often used in laptop and cell phone batteries, while LiOH is normally used in high performance electric vehicle batteries.
As the demand for electric vehicles capable of long-distance driving increases, each lithium secondary battery manufacturer is developing new ideas, with the goal of adding a large amount of Ni to the cathode material for high energy battery density, and the demand for LiOH is on the increase. It can easily be synthesized with Ni, which is added to the cathode material. In addition, Li and its compounds are applied not only to the primary use of batteries, but also to several other industrial applications, including heat-resistant glass, ceramics and high strength heavy alloys used in aircraft.
Glolinx is making ceaseless efforts to provide optimum condition products to customers in Korea and Japan through strategic business relations with China's LiOH manufacturers, known to have the best quality and price competitiveness in the world.

Cathode Material Demand Outlook

As the demand for products using rechargeable batteries, such as EV and ESS, increases, so the demand for cathode materials (NCM), which accounts for about 40% of the materials constituting secondary batteries, is increasing.

LiOH Demand Forecast

The higher demand for secondary batteries, the higher demand for Li. Glolinx is constantly striving for a stable supply of Li to the global market.
