Researchers develop real-time picture of formation of solid–electrolyte interphase of a Li-ion battery

Green Car Congress

During the first charging process of a new Li-ion battery cell, trace amounts of electrolyte components decompose sacrificially to form what is called a solid–electrolyte interphase (SEI) on the anode surface. Then the team analyzed the SEI components using a mass spectrometer. —Zihua Zhu.

Roskill: Niobium industry looking for a future beyond steel; Li-ion batteries a possibility

Green Car Congress

Non-steel applications account only for a couple of percentage points in terms of consumption but electrical vehicles (EVs) batteries and nanocrystalline applications could grow at a double-digit rate in the next decade, depending on technological developments. Niobium and batteries. The paper (Griffith et al. ) Griffith et al.
