LITHIUM CYLINDRICAL CELLS

With personal grooming devices such as electric toothbrushes, shavers, percussive therapy guns, electronic cigarettes and vaping devices, and consumer devices such as smart cameras, smart meters, earphones, and smart healthcare… the need for the simple but effective rechargeable battery continues to grow as technology evolves.

The foundation for the functionality of these products lies with lithium cylindrical cells, which can perform to high levels despite their small size. They can be used individually but can also be built into battery packs depending on the application.

Choosing Between the 18650 and 14500 Lithium Batteries

YOK Energy works with manufacturers to select the optimum cylindrical battery solution – selecting the battery size – whether the 18650, the 14500, or the 27500 – and adapting their configuration according to the individual product’s need.

The two most common formats are the 18650 rechargeable batteries and the 14500-battery size.

Inherent Battery Safety

There are two types of 18650 – protected and unprotected. Protected cells incorporate a circuit that prevents the cell from being overcharged. With this protective circuit, the battery cell can be overcharged and potentially cause a fire. The unprotected variety may be cheaper, but its use is only recommended when its use and recharging are externally monitored and controlled. Otherwise, the risk is too great. YOK Energy lithium batteries are manufactured with built-in safety measures as standard.

Working with YOK Energy

Working with a trusted battery supplier will guarantee that the product you manufacture is fitted with a bespoke rechargeable battery delivering the right level of voltage, distributed in a consistent, constant manner, with safety measures incorporated into the internal design of the cells as a whole.

If you are confused as to whether you should choose the 14500 or 18650 cells for your specific application, we may have something even more suitable. Our team will be on hand to guide you through the entire design and manufacturing process.
