(Continued from Part 1.) Rechargables Rechargeable batteries come in a much wider variety of chemistries than primary ones, including nickel–cadmium (NiCd), nickel–metal hydride (NiMH) and various lithium-ion (Li-ion) and Lithium Polymer (LiPo) chemistries. It’s important to understand the ‘Li-ion’ and ‘LiPo’ aren’t specific chemistries, they’re categories of chemistries that use Lithium as one of the components of the electrolyte. Li-ion batteries use a liquid electrolyte, are usually cylindrical, and common chemistries include: Lithium Cobalt Oxide (LiCoO2, LCO): Known for high energy density and used in portable electronics like smartphones, tablets, and laptops. It has a nominal voltage of 3.60V with … The post Mobile Device Battery Management – Part 2, by J.M. appeared first on SurvivalBlog.com.
