A battery holder is disclosed having a base plate and a frame that is at least partially encircling in a lateral direction, the base plate and the frame are configured as sheet-metal components, and a lid. The base plate is configured in a trough-shaped manner and is manufactured as a formed sheet-metal component from a multilayered laminated composite steel, wherein an internal exterior layer is configured from an acid-resistant steel alloy and an outboard external layer of the laminated composite steel is configured from a stainless-steel alloy.

A power tool, such as an impact driver, includes a motor housing that houses a motor, and a battery-mount part to which a battery pack having a rated voltage of 18 V is mountable. A ratio of the maximum width of the motor housing to the maximum width of the battery pack is 0.75 or less. A forward/reverse-switching lever is slidable in a left-right direction to change the rotational direction of the motor and is disposed between the motor housing and the battery pack. A maximum-slide position of the forward/reverse-switching lever in the left-right direction is inward of a ground plane when the power tool is laid horizontally on its side on the ground plane.

A Dense Energy Ultra Cell (DEUC), a dielectric energy storage device and methods of fabrication therefor are provided. A DEUC element is fabricated using print technologies that deposit dielectric energy storage layers (406) and insulating layers (404) together being interleaved between electrode layers (403). The dielectric energy storage layers are created from a proprietary solution to enable printing of dielectric energy storage layers with high permittivity and a high internal resistivity to retain charge. The insulating layers (404) can be applied within the dielectric energy storage layers (406) bifurcating the dielectric energy storage layers for increased resistivity. As part of the fabrication process, the material deposition printer can apply multiple print heads each with different inks and materials (1301, 1302) to form composite material (1303) in the printed layers.

This invention relates to the protection system for battery current collectors in cameras mounted on a gun, bow, or shooting device. More particularly, the present invention relates to the system of protecting the current collectors from fracture in a camera attached to a gun barrel or shooting device as a result of recoil and shock and vibration during shooting device discharge.
