What materials are used in batteries?

For li-ion batteries the resource lithium is used primarly. Others are cobalt, nickel, mangan and graphit.

What is the function of electrolyte in a lithium-ion battery cell?

Electrolytes are substances (mostly  liquids) inside of the battery cell which are conductive thanks to the ion molecules. Thus the electrolyte allows the flow of energy between the electrodes. Often additives such as conductive salt or supplements for a better wetting and battery quality are added. The electrolyte filling is an essantial part of battery cell assembly. The machines provided by IP PowerSystems are able to fill all kind of battery cells with liquid electrolyte.

How can you add electrolyte to a li-ion battery cell?

Electrolyte filling takes place in a dry room, in a glovebox or with a hermetically sealed cell. The electrolyte is poured into the battery cell with a dosing needle or nozzles. We offer innovative processes for a quick and homogenous wetting without any foaming or contamination with electrolyte. Our machines can work fully automated, have a vacuum chamber with short evacuation time, pump back and rinsing function as well as pulsating and preheating of the electrolyte. To save costs for big dry rooms we invented the smart battery innovation: a port technology for the filling, formating and degassing of lithium-ion pouch cells.

How does an electrolyte filling machine work?

Electrolyte filling machines are used to fill electrolyte into a li-ion battery cell. The range reaches from big manufacturing facilities to small R&D and laboratory equipment. Our machines are rather the latter as they provide filling modules for prototyping and small series for in-house research lines. The lib electrolyte filling with our equipment is very precise, traceable as well as documentable.

How do you manufacture lithium ion batteries?

Lithium-Ion battery production takes a lot of different work steps and resources.
First the electrodes are manufactured: different materials are mixed to a paste (slury) for the anode and cathode. This mixture is applied on a metallic foil, tried and after that compressed, slitted and cut to size.
Afterwards the battery cells are assemblied: anode, separator and cathode are piled up one after the other in turns to a cell stack or wrap. Next the tabs are fixed and the cell stack is placed in its case. Now the cells are filled with electrolyte.
Finished battery cells can be combined to modules or battery packs which are used as powerful lithium-ion accumulators for e-mobility.

What is a pouch battery?

The pouch battery cell has no hardcase structure but a laminated aluminium or plastic outer shell. That way it can be produced in different shapes or sizes (often prismatic) and is more cost and energy effective with less weight. However producing lithium-ion pouch battery cells is more challenging. That is why we invented the smart battery innovation – a novel port technology for electrolyte filling of pouch cells without a dry room and less hazardous waste.

How do lithium-ion accumulators work?

When we use li-ion battery packs or accumulators the following happens: negative electrones are set free at the anode and are transfered to the cathode. During this process chemical energy is transformed to electronical energy which we can use for our devices. While charging, the electrones are transfered to the anode again while the lithium travels through the separator to the anode with graphit layer. The battery is charged again.

Where do we use li-ion batteries also known as lib?

Li-ion batteries are present in our every day lifes. Smaller ones can be found in smartphones, small electronic devices and tools, bigger ones in e-bikes or for e-mobility, in bigger electronic or garden tools.

Why do we use lithium-ion battery packs?

Lithium-ion battery packs have a lot of advantages compared to conventional battery cells: they are rechargeable with a long life period and a high discharge rate. Moreover li-ion batteries provide a great energy density and conductivity despite small cells. Hence we are able to use electronic devices mobile over a long period of time and just recharge them if neccessary.
