System Background 1. **Quality Management System**: – The 2015 version of ISO9001 “Quality Management Systems Requirements” was officially released on September 23, 2015. – The Chinese national standard GB/T19001-2016 was officially released on December 30, 2016. – After its release, GB/T19001-2016 will replace GB/T19001-2008 as the basis for quality management system certification. The transition period…
Sodium-ion batteries are a type of secondary battery that primarily relies on the movement of sodium ions between the positive and negative electrodes to complete the charging and discharging process. These batteries are similar to lithium-ion batteries in terms of their working principle. However, since sodium and lithium are elements of the same main group,…
All-solid-state batteries are a type of battery technology characterized by the use of solid electrolytes instead of traditional liquid electrolytes. In these batteries, every component is in a solid state, including the cathode, anode, and solid electrolyte. The main advantages of all-solid-state batteries include: ★ High Safety: As they do not use flammable organic solvents,…
Lithium-ion batteries are secondary rechargeable batteries that primarily operate through the movement of lithium ions (Li+) between the positive and negative electrodes. During the charging and discharging process, Li+ ions shuttle between the two electrodes by intercalating and de-intercalating: when charging, Li+ ions de-intercalate from the positive electrode, pass through the electrolyte, and intercalate into…
Introduction to Metallic Lithium Lithium is a metallic element, positioned at the forefront of metals in the periodic table. Its chemical symbol is Li, and it is a silver-white, extremely soft, and highly reactive metal. It is the lightest metal among all metals, and in lithium batteries, it is typically used in the form of…
