lithium-ion battery construction and working pdf

  Lithium-ion Battery Working The rechargeable  lithium-ion battery  is made of one or more power-generating compartments called cells. Each cell has essentially three components.- positive electrode, negative electrode and electrolyte. A  positive electrode  connects to the battery's positive or + terminal. A  negative electrode  connects to the negative or − terminal. And a chemical called an  electrolyte  in between them. The positive electrode is typically made from a chemical compound called  lithium-cobalt oxide (LiCoO 2 )  or  lithium iron phosphate (LiFePO 4 ) . The negative electrode is generally made from carbon (graphite). The electrolyte varies from one type of battery to another. Advantages of Lithium-ion Battery Now a days Lithium-ion batteries are popular because they have a number of important advantages over competing technologies: Generally, they are much lighter than other types of rechargeable batteries of t...

Most lithium-ion battery pack designs

Most lithium-ion battery pack designs involving cylindrical, pouch or prismatic automotive cell. A typical battery pack case assembly includes a lower case in which the battery pack is accommodated, and a cover assembled to cover an upper surface of the lower case , and various structural reinforcing members (cross members, side members, etc.), and the battery pack together with a battery controller (Battery Management System, BMS) ) And related parts such as cooling blowers are mounted together. The weight reduction of the vehicle is a major challenge in the development of the electric vehicle, and thus, attempts to use the lightweight material for various parts of the electric vehicle are more important. The upper cover does not greatly support the load, it can be manufactured by a general plastic composite molding method, but for the lower case and the structural reinforcement In the case of members, steel parts are separately press-molded to withstand battery load or steel re...
