100MWH EV Car Battery Prismatic Cell Aluminium Case Cell Pilot Scale Manufacturing Line
Prismatic Cell:
Prismatic cell is often used for high capacity battery applications to optimise the use of space. These designs use a stacked electrode structure in which the anode and cathode foils are cut into individual electrode plates which are stacked alternately and kept apart by the separator. The separator may be cut to the same size as the electrodes but more likely it is applied in a long strip wound in a zig zag fashion between alternate electrodes in the stack.

The process for prismatic cell is illustrated in the following diagram:
The anodes and cathodes in Lithium cells are of similar form and are made by similar processes on similar or identical equipment. The active electrode materials are coated on both sides of metallic foils which act as the current collectors conducting the current in and out of the cell. The anode material is a form of Carbon and the cathode is a Lithium metal oxide. Both of these materials are delivered to the factory in the form of black powder and to the untrained eye they are almost indistinguishable from eachother. Since contamination between the anode and cathode materials will ruin the battery, great care must be taken to prevent these materials from coming into contact with eachother. For this reason the anodes and cathodes are usually processed in different rooms.
Slitting:
The electrode shall be slit according to the size of the battery to be produced.
Liquid injection and formation:
The formation of lithium battery mainly has two functions: one is to convert the active substances in the battery into substances with normal electrochemical action by means of the first charge; The other is to form an effective passive film or SEI film on the electrode, mainly the anode.
Battery Pack Assembling:
After the single battery is made. Grouping and series parallel connection of these batteries become the foundation of electric vehicle power battery system - Battery Module.
