Abstract: Camera head apparatus, systems, and methods for providing wide angle/panoramic images and/or video of the interior of pipes or other cavities using multiple imaging and illumination modules are disclosed.

Abstract: An anode for an energy storage device includes a current collector having an electrically conductive layer and a surface layer disposed over the electrically conductive layer. The surface layer may include a first surface sublayer proximate the electrically conductive layer and a second surface sublayer disposed over the first surface sublayer. The first surface sublayer may include zinc. The second surface sublayer may include a metal-oxygen compound, wherein the metal-oxygen compound includes a transition metal other than zinc. The current collector may be characterized by a surface roughness Ra ? 250 nm. The anode further includes a continuous porous lithium storage layer overlaying the surface layer. The continuous porous lithium storage layer may have an average thickness of at least 7 µm, may include at least 40 atomic % silicon, germanium, or a combination thereof, and may be substantially free of carbon-based binders.
