ENPLUS Develops Liquid Graphene to Maximize Secondary Battery Efficiency... "Solving Delamination Issue"

[Asia Economy Reporter Hyunseok Yoo] ENPlus announced on the 22nd that it has succeeded in developing 'liquid graphene' applicable as a secondary battery material. In particular, the newly developed 'liquid graphene' is a material used for graphene coating and can be complexly applied to various materials.

Regarding secondary batteries, the issue of electrolyte delamination, which had been a limitation in the use of graphene, has been resolved, and graphene is expected to be actively utilized in the secondary battery market.

Graphene has attracted attention as a 'dream new material,' but until now, problems occurred during the graphene coating process, such as the separation of layers between graphene and binders in the liquid form and the large specific surface area of graphene. Due to nozzle clogging, uneven coating, and delamination caused by the secondary battery electrolyte, it was difficult to apply graphene despite its excellent performance potential. However, ENPlus succeeded in developing a graphene coating solution that solves these issues through nano-composite technology. It has already completed prototype evaluations for conductive materials for cathodes and anodes of secondary batteries and heat dissipation materials, and has placed initial mass production orders with Standard Graphene.

An ENPlus official stated, "Recently, the development of secondary batteries with high-capacity energy density has been expanding to improve driving range, but existing materials face problems in stability tests according to the high-capacity energy density," adding, "The graphene solution developed by ENPlus is attracting much attention as a graphene coating solution that can increase the capacity of secondary batteries while improving stability."

He continued, "We are already discussing the supply of graphene coating solutions designed to vary resistance without reducing capacity to improve secondary battery stability, mainly with overseas electric vehicle makers such as those in China," he added.

Overseas electric vehicle makers are attempting to use lithium iron phosphate as the cathode electrode to enhance the stability of secondary batteries. However, lithium iron phosphate has not been adopted due to its shorter lifespan and lower efficiency compared to existing cathode electrode materials. Using graphene coating solution enables the utilization of lithium iron phosphate. When graphene coating solution is applied to both cathode and anode followed by lithium iron phosphate, improvements in lifespan and efficiency are observed, drawing attention from overseas electric vehicle companies.

In addition, discussions on supplying heat dissipation sheets coated with graphene coating solution are planned soon. Graphene-coated heat dissipation sheets are more efficient than conventional graphite heat dissipation sheets, effectively lowering temperature and can be applied to secondary batteries. ENPlus plans to proceed with consultations with major clients as soon as related patent applications are completed.
