Abstract:
The present invention relates to a method of manufacturing a porous carbon-silicon composite using a spray drying method, and a porous carbon-silicon composite manufactured by the method of manufacturing a porous carbon-silicon composite. The method according to an embodiment of the present invention uses a spray drying process, thereby minimizing a manufacturing step, and can achieve mass production through a continuous process. In addition, the porous carbon-silicon composite manufactured by the method minimizes a volume increase caused by the introduction of lithium ions, thereby improving the performance of a lithium secondary battery.
Abstract:
The present invention relates to a pre-treatment method of an anode active material. More specifically, the present invention relating to the pre-treatment method of an anode active material wherein a formation at high pressures for an initial activation is essential, and in the same activation process, a manganese-rich anode material having a large irreversible capacity, along with a large quantity of gas, is treated with a reduction and a lithium-consuming treatment, so as to enable the activation of the manganese-rich material at low voltage, reduce the initial irreversible capacity, and improve capacity and lifespan.
Abstract:
본 발명은 표면을 내산화성 물질로 코팅한 도전성 구리 분말로서, 상기 내산화성물질은 구리 분말보다 내산화성이 크고, 소성온도가 낮은 물질인 것이 특징인 도전성 구리 분말, 그 제조방법 및 상기 도전성 구리 분말을 포함하는 도전성 페이스트를 제공한다. 본 발명에 의하면, 도전성 구리 분말의 표면을 유리 또는 은(Ag) 등의 내산화성 물질로 코팅함으로써, 구리 분말의 산화를 방지할 수 있어, 전극 페이스트에 사용시 우수한 전기 전도 특성을 나타낼 수 있으며, 전극의 소성온도를 낮추어 전극의 형성을 용이하게 할 수 있다.
