Basic knowledge and manufacturing process of lithium-ion batteries

Leave a Comment / Safety Standard / By

Introduction The production process of lithium-ion batteries is divided into four main processes: pole piece production, battery cell (cell) production, cell activation detection, and battery packaging. The production of pole pieces includes the processes of pulping, coating, rolling, slitting, sheet making, and tab forming. It is the basis of lithium-ion battery manufacturing and has high …

Why lithium ion batteries burn or even explode?

Leave a Comment / Safety Standard / By

Introduction Lithium ion batteries are compact, lightweight batteries that hold considerable charge and fare well under constant discharge-recharge conditions. The batteries are found everywhere — in laptop computers, cameras, cell phones, and electric cars. Although accidents are rare, those that do occur may be spectacular, resulting in an explosion or fire. It can be seen that, theoretically, a …
