Standard and custom Li-ion batteries
Lithium-ion batteries appeared in the early 1990’s and were first marketed by Sony. These batteries now have a leading position on the rechargeable battery market. Their main advantage is their high energy density (two to five times higher than Nickel Metal Hydride, for instance).
Lithium-ion or Li-Ion batteries are based on the reversible exchange of lithium-ions between the positive electrode, usually made from cobalt or manganese dioxide, and the negative electrode made from graphite.
As a leading custom Lithium-ion-battery pack assembler, we hold a very wide range of industrial cells in stock to offer the most comprehensive range of battery packs on the market.
As the choice of cell is a key component of battery performance based on the energy requirement, the budget and the application, we stock the majority of lithium-ion cells available on the market. Panasonic, LG, Samsung, Sony Murata, Molicel and Saft are brands we always keep in stock. We also keep most sizes available for current supply but also for new projects like popular 18650 cells but also 18500, 14500, 21700, D and several prismatic cells such as the very popular 103450 cell.
STANDARD LITHIUM-ION BATTERY PACKS
We have developed a UN38.3 and IEC 62133v2 approved range of standard battery packs with BAK cells that covers a wide range of applications, allowing our customers to access a comprehensive offer without high MOQs and certification costs.

Advantages of our Lithium-Ion battery packs:
COBALT VS MANGANESE
Although cobalt has been used for a longer period of time, manganese is by nature less dangerous even when the cells are misused so the protection circuits can be simplified. In addition to improved safety, the cost of manganese as a raw material is lower than the cost of cobalt. On the other hand, it has a lower energy density, its capacity drops at temperatures higher than 40°C and it ages faster than cobalt. Take a look at the advantages and disadvantages of the two chemical compositions below.
Energy Density (Wh/Kg)
When there is an overload, the cobalt electrode supplies excess lithium that can be transformed into metallic lithium, which leads to a potential safety risk if it is not protected by a protection circuit.
During an overload, the manganese electrode has a lower lithium content which means that only the element heats up. The protection circuits can be simplified for the small 1 and 2 cell packs.
Wide range of temperatures. Best suited to work at high temperatures.
Loses capacity above 40°C. Not as resistant at higher temperatures.
Short term storage is possible. The impedance increases with time. The new versions can be stored for longer.
Short term storage possibility is slightly lower than with cobalt.
The impedance does not change much during the life cycle of the element. The shelf life is difficult to predict because of continuous improvements to the chemistry.
300 cycles, capacity of 50% at the 500th cycle
Can be shorter than cobalt.
The cost of the raw materials is high and a protection circuit increases the cost.
Raw material is 30% cheaper than the cobalt. A simplified protection circuit is a real advantage in terms of cost.
