In a large operation, the cans are made at the battery factory using standard cutting and forming techniques. An indentation is made near the top of the can, and an asphalt or epoxy sealant is placed above the indentation to protect against leakage.
When battery manufacturers are planning a new production facility, they consider a number of factors to ensure a successful and efficient operation. Here are five key issues they address: Site Selection and Infrastructure: Choosing the right location for a new production facility is crucial.
The lithium-ion battery manufacturing process is a journey from raw materials to the power sources that energize our daily lives. It begins with the careful preparation of electrodes, constructing the cathode from a lithium compound and the anode from graphite.
What’s inside a battery? A battery consists of three major components – the two electrodes and the electrolyte. But the commercial batteries consist of a few more components that make them reliable and easy to use. In simple words, the battery produces electricity when the two electrodes immersed in the electrolyte react together.
The industrial production of lithium-ion batteries usually involves 50+ individual processes. These processes can be split into three stages: electrode manufacturing, cell fabrication, formation and integration. Equipment plays a critical role in determining the performance and cost of lithium-ion batteries.
The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
