Abstract: The present invention is related to a material of negative electrode for a lithium secondary battery manufactured by alloying a material which does not form silicon and intermetallic compounds with silicon through the arc melting alloying. More particularly, the present disclosure is related to a material of negative electrode for lithium secondary battery wherein the capacity and life expectancy have been improved by mixing silicon and five or more kinds of metals which do not form an intermetallic compound with silicon to have almost the same atomic ratio in order to improve the volume expansion problem and initial efficiency characteristics of silicon when using silicon as the anode active material of a lithium secondary battery and by applying a buffering action to the volume expansion of the silicon in the charging and discharging process of the electrode through the use of high entropy alloy manufactured by alloying through arc melting.

Abstract: A 3-dimensional printing apparatus may include a storage unit, a dispensing unit, and a pressure control unit. The storage unit stores a printing material satisfying Bingham plastic model in which a viscosity is decreased as a pressure is increased. The dispensing unit receives the printing material from the storage unit to ejaculate the printing material. The pressure control unit controls a pressure applied to the printing material supplied in the dispensing unit to control a viscosity of the printing material. Thus, a product having soft characteristics may be manufactured.
