Abstract: A golf club with a golf club head having non-metallic fasteners is presented. The club head may include a face member, a body member, a sole member and a crown member. The various portions of the club head may be connected using mechanical fasteners, such as screws. In some arrangements, the screws may be formed of a non-metallic material, such as a composite material, in order to reduce weight associated with the club head. In some arrangements, a portion of the mechanical fasteners may be formed of a non-metallic material and may be placed in regions of the club head where reduced weight is desired, while another portion of the fasteners may be formed of metal or other heavier material and may be placed in regions where additional weight may be desired.

Abstract: Methods for operating open electrochemical cells are disclosed. The open electrochemical cells generally comprise a cathode, an electrolyte, and an anode. One example cathode comprises: (i) a catalyst; (ii) an electronic conductor and (iii) a hydrophobic gas permeable binder. The open electrochemical cells may be operated as metal-air batteries, for example, in devices comprising the open electrochemical cells.

Abstract: A golf club head includes a face plate and a body member positioned rearwardly of the face plate and having at least two body components. Each of a plurality of apertures is formed in one of the face plate and the body components. At least one fastener extends through at least two of the apertures, the fasteners being configured to removably secure the face plate and the body components together upon being turned a portion of a revolution.

Abstract: A golf club head includes a club head having a plurality of components and a plurality of retaining members, with each retaining member positioned on one of the components. A tensioning assembly for releasably securing the components of the club head together includes a tension element coupled to the club head components by way of the retaining members, and a tensioning member for introducing tension into the tension element.
