摘要： When a lithium metal negative electrode having a capacity of 3,860 mAh/g is used instead of a graphite negative electrode having a capacity of 372 mAh/g to improve the energy density of a lithium secondary battery, the energy density can be improved approximately 10 times. However, the lithium metal negative electrode has a disadvantage in that dendrite is formed according to repeated cycles, the battery is short circuited, and as a result, the secondary battery explodes. The dendrite significantly reduces the capacity and lifespan of the secondary battery. The present invention effectively inhibits the growth of dendrites and improves the capacity and lifespan of the secondary battery by coating lithium metal with a polymer with a functional group having an oxygen atom in the molecular structure to which free radical is attached. The above polymer has a high rate of charge transfer during the electrochemical reaction and transfers lithium ions to lithium metal by ion exchange.

摘要： In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

摘要： The present invention is a technology for replacing a lithium ion secondary battery using an inorganic material, which is currently commercially available, and is a technology for constructing a secondary battery using an organic material as an electrode material. The organic electrode has a disadvantage in that the actual energy density is low because it has to include a large amount of carbon-based conductor in the electrode due to poor electrical conductivity. In order to overcome this drawback, in the present invention, the loading amount of the organic active material in the electrode is increased by filling the pores of the carbon structure body, such as porous activated carbon, with an organic electrode material and coating the outside of the carbon structure body with an organic electrode material. In addition, by using a carbon material current collector instead of the conventional metal current collector such as Al or Cu, a flexible and binder-free organic electrode was fabricated to increase the loading amount, reduce the weight of the battery, and improve the electrochemical properties.

摘要： Inorganic-based lithium mixed electrode materials have a low charge transfer rate and thus have poor fast charging or discharging characteristics. Positive electrode active materials include LCO (lithium cobalt oxide, LiCoO2), NCM (nickel cobalt manganese, Li(NiCoMn)O2), NCA(nickel cobalt aluminum, Li(NiCoAl)O2), LMO(lithium manganese oxide, LiMn2O4), LFP(Lithium iron phosphate, LiFePO4), etc. High nickel technology is attracting attention because if nickel is used a lot, the capacity of lithium ions can be increased. However, as the content of nickel increases, the reactivity increases, resulting in a risk of explosion of the battery and deterioration in cycle life characteristics. As the negative active material, carbon, transition metal oxide, nickel metal, silicon-nickel alloy, and the like may be used. As the carbon, natural graphite, artificial graphite, soft carbon, hard carbon, etc. can be used. As the transition metal oxide, Co3O4, CoO, FeO, NiO, and the like can be used.
The present invention adds a polymer additive containing free radicals in the molecular structure to the electrode to solve the problems of the existing secondary battery. The polymer additive contains free radicals and undergoes an oxidation-reduction reaction through ionic interactions. When this polymer additive is included in the electrode, the fast charging and fast discharging characteristics are improved, and the stability of the electrode is improved. When the stability of the electrode is improved, the cycle life characteristics of the electrode are improved. Because the polymer additive participates in the electrochemical reaction, it increases the practical capacity of nickel. When dissolved in a solvent, the polymer additive can increase the viscosity and act as a binder.

摘要： A multi-layer structured composite electrolyte for a secondary battery and a secondary battery using the same are provided. The multi-layer structured composite electrolyte is made by laminating two or more layers of a composite electrolyte including a small amount of a liquid electrolyte in a mixture of a polymer and a ceramic material. The multi-layer structured composite electrolyte has the same stability as a solid electrolyte and has the same or better electrochemical properties as or than the liquid electrolyte. Since the multi-layer structured composite electrolyte of the present invention can be folded arbitrarily, the multi-layer structured composite electrolyte may be used in a wearable device.
