Title
(EN) NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING ELECTRODE USING SAME, AND SODIUM SECONDARY BATTERY INCLUDING SAME
(KO) 나트륨 이차전지용 음극활물질, 이를 이용한 전극의 제조방법 및 이를 포함하는 나트륨 이차전지
Abstract
(EN) The present invention relates to a negative electrode active material for a sodium secondary battery, an electrode using the same, and the sodium secondary battery including the same. The negative electrode active material for the sodium secondary battery according to the present invention comprises a phosphorus-carbon composite, wherein phosphorus in the phosphorus-carbon composite is at least one among red phosphorus, black phosphorus, white phosphorus, and yellow phosphorus. The present invention can realize the sodium secondary battery having increased reactivity with sodium, thereby having a high reversible capacity per weight and a low charging and discharging voltage.
