Publication number: US20220029066A1
Application number: 17/450,621

A method of producing a light source device includes providing a light emitting device having a substrate including a base member that includes a bottom surface and a recess. The substrate further including a wiring portion in the recess. The method further including providing a support substrate having a support base member, a first wiring pattern on a top surface of the support base member and including a joining region, and an insulating region, and applying a solder member such that the solder member on the insulating region has a volume larger than that of the solder member on the joining region. The light emitting device is placed on the support substrate while the solder member is separate from a portion of the wiring portion positioned in the vicinity of the bottom surface and the wiring portion is joined to the joining region.

Application number: 17/493,901

An electrode for nonaqueous electrolyte secondary batteries, provided with a collector and a positive electrode active material layer arranged on the collector and contains a positive electrode active material. The positive electrode active material contains compound particles which have a layered structure composed of two or more transition metals, and which have an average particle diameter DSEM of from 1 μm to 7 μm (inclusive) based on the observation with an electron microscope, a ratio of the 50% particle diameter D50 in a volume-based cumulative particle size distribution to the average particle diameter DSEM, namely D50/DSEM of from 1 to 4 (inclusive), and a ratio of the 90% particle diameter D90 in the volume-based cumulative particle size distribution to the 10% particle diameter D10 in the volume-based cumulative particle size distribution, namely D90/D10 of 4 or less. The positive electrode active material layer has a void fraction of 10-45%.
