    摘要： A filtering face mask 10 that has a harness 14 and a mask body 12. The mask body 12 is structured such that a snug facial fit can be achieved without use of additional components such as an elastomeric face seal, nose foam, or nose clip. The mask body 12 includes a filtering structure 18 and a cup-shaped shaping layer 20 where the latter comprises a closed cell foam layer that has a plurality of fluid permeable openings located in it. The openings occupy at least 30% of the total surface area of the shaping layer, including a mid region of the shaping layer. The filtering structure is coextensively disposed over the shaping layer. The shaping layer 20 makes contact with the wearer's face at the mask body perimeter 19 when the respirator is being worn. Despite the open nature of the foam shaping layer over much of its surface area, the use of a foam shaping layer, in conjunction with a coextensive filtering structure, provides sufficient structural integrity or stiffness to prevent mask body collapse during respirator use while also exhibiting a low pressure drop to allow for low breathing resistance and extended wearer comfort.

    摘要翻译： 具有线束14和面罩主体12的过滤面罩10.面罩主体12被构造成使得可以在不使用诸如弹性体面部密封件，鼻部泡沫或鼻夹的附加部件的情况下实现舒适的面部配合。 面罩主体12包括过滤结​​构18和杯形成形层20，其中后者包括具有多个位于其中的流体可渗透开口的闭孔泡沫层。 这些开口占成形层的总表面面积的至少30％，包括成形层的中间区域。 过滤结构共同设置在成形层上。 当佩戴呼吸器时，成形层20在面具主体周边19处与穿着者的脸部接触。 尽管泡沫成型层在其大部分表面积上具有开放性质，但是使用泡沫成形层与共延伸的过滤结构相结合，提供了足够的结构完整性或刚度，以防止呼吸器使用期间的面罩体塌陷，同时也显示出 低压降以允许低呼吸阻力和延长佩戴者的舒适度。

    摘要： A respirator 10 that includes a mask body 12 and at least one filter cartridge 24. The mask body 12 has a central portion 14 and a peripheral portion 16. The filter cartridge 24 is attached to the rigid central portion 16. The peripheral portion 14 is made from a low stiffness first thermoplastic material, and the central portion 16 is made from a rigid second thermoplastic material. The first thermoplastic material is welded to the second thermoplastic material. A respirator of this structure can be made in a convenient manner, with a sound hermetic bond between the parts, while also being light in weight.

The negative active material includes a compound represented by the Formula Li1+xV1-x-yMyO2+z. In one embodiment, the compound has an average particle size ranging from about 50 nm to about 30 μm. In another embodiment, the negative active material has a ratio of (003) plane diffraction intensity to (104) plane diffraction intensity ranging from about 1:1 to about 1:0.01 when measured using a Cu K α X-ray. According to another embodiment, after five charge/discharge cycles performed at 0.5C, a specific surface area of the negative active material increases to less than about 20 times a specific surface area before the five charge/discharge cycles. The negative active materials may improve battery capacity, and cycle-life characteristics.
