GLOBAL LI-ION BATTERY ASSEMBLING MACHINE MARKET INTRODUCTION The three primary steps in the creation of a lithium-ion battery cell […]
The three primary steps in the creation of a lithium-ion battery cell are electrode manufacturing, cell assembly, and cell finishing.
Each of these steps is broken down into smaller steps that start with coating the anode and cathode, move on to assembling the various parts, and finish with packing and testing the battery cells.
Li-ion batteries have four main parts: an electrolyte medium that allows lithium ions to move between the electrodes, a separator that is positioned between the electrodes to prevent contact and shorting, and two electrodes: one anode (holds the lithium ions when charged) and one cathode (holds the lithium ions when discharged).
The cathode can be an alloy of different metals, while the anode is often composed of graphite (nickel, cobalt, lithium, others).
The positive and negative terminal tabs are exposed, and the entire assembly is housed in a casing. A battery pack is created by placing and connecting the cells.
In order to create a homogenous slurry with the solvent, the electrode materials must first be combined with a conductive binder.
(A type of carbon serves as the anode, and a lithium metal oxide serves as the cathode. The processing of the anodes and cathodes typically takes place in separate rooms to prevent cross-contamination between the two active materials.)
The current collector is then coated with the slurry, either continuously or irregularly.
The Global Li-Ion Battery Assembling Machine Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Lithium ion batteries are created as sets of electrodes, which are then put together to form cells.
In order to generate a porous electrode coating, the active material is combined with polymer binders, conductive additives, and solvents to create a slurry.
This slurry is then coated on a current collector foil and dried to remove the solvent. The preferred solvent, N-methylpyrrolidone (NMP), is expensive, produces volatile vapours, and is extremely hazardous.
It is classified as an indirect substance because it is required for manufacture but not included in the finished product.
All processing machinery used to make electrodes must be explosion-proof due to the flammable vapours of NMP, which also mandates that all spark-producing electrical components be protected from the vapours and that areas be well ventilated to maintain low vapour concentrations.
