I am redeveloping a product that literally billions of people use, from every day to at least once a month. I need some help designing the power portion, as I am not an engineer.

I am planning on using the GTL ICR18650 3.7V 3000 mAh Lithium Battery because it provides the power needed, as well as cost efficiency. Now to charge this battery as well as to power this device using lower power than the battery (ie. solar panel) I found the Texas Instruments LM2623 boost converter to step-up the voltage and regulate the amperage. Would this work?

I am also having troubles finding a charger for this device. Could anyone suggest any that are well suited and cost effective?
