The work shows that the extrusion-based coating process is a highly promising alternative for the efficient production of lithium-ion batteries. 1. Introduction The development of affordable and reliable battery systems for mobile or stationary applications is an essential step towards a sustainable energy economy.
One of the key components of a lithium-ion battery is separator film. It can help to prevent short-circuiting and stop thermal runaways with its special thermal shutdown properties, all while still facilitating the flow of charged ions. The safety and efficiency of separator film can be improved by coating it with materials such as ceramic.
Scheme of the developed extrusion-based manufacturing process for thick cathodes for Li-ion batteries. First, the AM and CB powders are mixed in a dry mixing step with low intensity. Subsequently, the powder mixture and the binder solution are granulated (solid content 85 wt%) prior to the extrusion step.
Nevertheless, the reported work so far have only concentrated on thin films of electrophoretically deposited electrodes for energy storage. Here, the electrochemical performance of thick films (up to tens of μm) as lithium-ion battery electrodes produced by EPD is reported.
Office of Energy Efficiency & Renewable Energy explains how a Lithium-ion battery works: “A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium.
The process involves three key stages: (1) preparation of colloidal electrolyte, (2) electrophoretic deposition of battery materials onto the working electrode, and finally (3) drying the deposited electrode and use directly as Lithium-ion battery cathode.
The adhesive tape used in the lithium battery industry
3、Power insulation blue film tape With the rise of power batteries, the emergence of double-layer protective films for power has also come into being. It is obvious that the protective film originally used for pouch batteries can no longer meet the technological developments and advancements in power battery packaging.
