South Korea Has Developed A High Performance Anode Binder For Lithium-ion Batteries

South Korea research consortium said in a news release, joint chungnam university, the sun engineering university jointly developed a new type of adhesive with high voltage and high capacity anode material, greatly improves the energy density of lithium secondary batteries.The research was published in the international journal Advanced Functional Materials.

The current use of lithium cobalt oxide (LiCoO2) and nickel-cobalt manganese (NCM) capacity is limited and requires a larger anode material.As a new generation of anode materials, lithium manganese oxide is highly anticipated. It is twice as high as lithium cobalt oxide energy, but only increases the charging voltage to more than 4.4V to obtain high capacity.In this case, however, the secondary battery heats up, weakening the adhesion of the adhesive and causing the battery's performance to weaken.

South Korea is committed to developing high energy density secondary batteries.Team development of anode materials is in the high voltage of 4.7 V and 55 degrees high temperatures, in extreme form a protective film, maintain stable interface, requires no additional electrolyte additives, also can maintain stable viscosity adhesive materials, more than currently used cobalt acid lithium oxide 2 times more capacity and more stable charge and discharge performance.The team said the technology could further boost the development of secondary batteries.
