Lithium-ion Battery

We manufacture and sell separators, one of the four main materials used in lithium-ion batteries, possessing the technology of environmentally friendly water-based slurry that increases the safety of the battery.

Secondary batteries are batteries that can be reused by repeatedly charging and discharging. Compared to primary batteries, which are discarded after use, secondary batteries are more economical and environmentally friendly, and are attracting attention as a means to lead the Fourth Industrial Revolution and a zero-carbon society.

A lithium-ion battery is a battery that uses a compound containing a metal called lithium in the electrodes and discharges by the movement of lithium ions. The lithium ions move back and forth between the electrodes to discharge and charge.

LiBS is a permeable membrane placed between the anode and cathode. The main function of the separator is to keep the two electrodes apart to prevent the explosion. It carefully lets only the ions pass through the internal microscopic hole with no electrical conductivity. Furthermore, the shutdown function blocks up micro-pores when thermal runaway occurs by internal or external short circuits.

Next-Generation Bettery

We are developing technology for Sodium-ion (Na), Lithium-Metal, and Lithium-Sulfur batteries to advance the performance, generate profit, and be eco-friendly through the application of existing facilities, to become a innovation leader.

The solid-state battery, the "dream battery", is composed of solid materials: anode, cathode, and electrolyte. It is gaining attention as the next-generation battery for its advantages. The solid-state battery is combined with the function of electrolyte and separator that enables high energy density for efficiency, which leads to being safe and eco-friendly.

Solid electrolytes that combine the functions of electrolyte and separator in lithium-ion batteries are classified into sulfide-based, oxide-based, and polymer-based electrolytes. WCP develops polymer-based electrolytes through existing facilities. Polymer electrolytes have the advantages of existing separator/liquid electrolytes and have higher interfacial affinity compared to solid-state electrolytes.

Ion-Exchange Membrane

We focuse the business on the core material 'ion exchange membrane', which is applicable in a broad spectrum of industries such as renewable energy, green mobility, and new green industry. The use of an ion exchange membrane for extracting lithium increases productivity and it is an eco-friendly method as it reduces wastewater, waste, and carbon dioxide emission.

An ion exchange membrane is a film that selectively separates ions through electrostatic repulsion. Depending on its characteristics, it can be classified as a cation exchange membrane, anion exchange membrane, and bipolar exchange membrane. Ion exchange membrane is applicable in diverse business fields: wastewater, energy, food and drink, medical purposes, and even hydrogen mobility.

We make use of existing membrane technology to develop greener materials with better durability and function. Our challenge is to diversify products to establish a supply chain to be applied in our lives.

BCF is a breathable and waterproof functional membrane material that is eco-friendlier than PFAS and has higher cost competitiveness than PTFE. BCF is applicable in a variety of products, even from affordable products to luxury products. Due to those benefits, it is in the phase of domestic production to replace PFAS.

Industrial chemical filter

We recognize the importance of environmental issues exposed by the rapid industrial development. Therefore, we are working on the development of an ultrapure material to contribute to green impact.

Industrial chemical filters are used in the process of manufacturing products to maintain the environment and increase productivity and quality. We are working on developing high-quality filters that are reliable to use for the treatment of industrial wastes and to manufacture ultrapure material for semiconductors and displays.
