摘要： Provided are a porous silicon-based anode active material including porous SiO x particles (0≤x x particles (0≤x x particles, a thickness change rate of the electrode generated during charge and discharge of a secondary battery may be reduced and lifetime characteristics may be improved.
摘要翻译： 本发明提供一种多孔硅基阳极活性材料包括多孔的SiO X粒子（0‰¤x<2）具有氧化物层，制备所述相同的方法，以及包括该多孔硅基阳极的锂二次电池涂有表面 活性材料。 由于负极活性物质包括在所述多孔的SiO X粒子形成的氧化物层（0‰¤x<2），在溶液中的阳极活性材料和电解质之间的反应性可以减小，并且，作为结果，在电短路 到电极可以最小化。 所以，由于孔的多元性被包括在表面或表面和内部在SiO X的颗粒，电荷和二次电池的放电过程中产生的电极的厚度变化率可以减小，并且寿命特性可以得到改善。

摘要： Provided are a porous silicon-based particle including a silicon (Si) or SiO x (0
Porous silicon-based particles according to an embodiment of the present invention may be more easily dispersed in an anode active material slurry, may minimize side reactions with an electrolyte, and may reduce volume expansion during charge and discharge.
Also, according to an embodiment of the present invention, the shape, form, and size of pores formed in the porous silicon-based particle may be controlled by adjusting the type of a metal catalyst, the concentration of the catalyst, and etching time.摘要翻译： 提供了包括硅（Si）或SiO x（0
