    • Provided are a porous anode active material, a method of preparing the same, and an anode and a lithium battery employing the same. The porous anode active material includes fine particles of metallic substance capable of forming a lithium alloy; a crystalline carboneous substance; and a porous carboneous material coating and attaching to the fine particles of metallic substance and the crystalline carboneous substance, the porous anode active material having pores exhibiting a bimodal size distribution with two pore diameter peaks as measured by a Barrett-Joyner-Halenda (BJH) pore size distribution from a nitrogen adsorption. The porous anode active material has the pores having a bimodal size distribution, and thus may efficiently remove a stress occurring due to a difference of expansion between a carboneous material and a metallic active material during charging and discharging. Further, the anode electrode and the lithium battery comprising the anode active material have excellent charge/discharge characteristics.
    • 提供一种多孔阳极活性材料,其制备方法,以及使用其的阳极和锂电池。 多孔负极活性物质包括能够形成锂合金的金属物质微粒; 结晶碳物质; 和多孔碳质材料涂覆并附着到金属物质和结晶碳质物质的细颗粒上,多孔负极活性物质具有双孔尺寸分布,具有两孔径峰,由Barrett-Joyner-Halenda(BJH)测量, 孔径分布从氮吸附。 多孔负极活性物质具有双峰尺寸分布的孔,因此可以有效地消除由于填充和排出期间碳质材料和金属活性物质之间的膨胀差而产生的应力。 此外,阳极电极和包含阳极活性材料的锂电池具有优异的充电/放电特性。
