Square Li-Po Battery vs. Cylindrical Cells: Key Differences Explained

Square Li-Po and cylindrical cell are two types of batteries widely used in many electronic products. There are a few general differences between the two types that we need to be aware of, and in this article, mitacbattery will dig into some of the main factors making them different as both offer distinct advantages according to requirement with an explanation on how each performs in what application. 

Comparison: Square Li-Po vs. Cylindrical Cell Batteries

Square Li-Po batteries, so-called pouch cells, are thin and flexible and well suited for slim devices such as smartphones or tablet PCs. Batteries are available in a range of sizes and thinnesses, which gives designers more possibilities to make products flat or smaller. Conversely, non-vape products like laptops and power tools are more likely to have cylindrical cells like the ubiquitous 18650 batteries. Being simple to stack and assemble, they are adequate for applications where the high energy density and power density is needed. 

Square Li-Po batteries have higher energy density than round cells, thus they can store more capacity in the same size space. This makes them a good candidate for the portable electronics where weight and size is an issue, such as cellular phones or other electronic devices which are characterized by little overall battery life per charge. However, cylindrical cells of the type generally utilized in power tools and electric vehicles have a higher power density, which is desirable for applications where high power is called for, such as electric vehicle motive power. Also Square Li-Po Battery packs are more likely to swell and get punctured due to the fact that they do not have the protective hard cover like a regular cylinder cell. This is a problem in applications where products must be fail-safe (eg: medical equipment, aerospace). 

Typical Use Problems Of Square Li-Po In Bulk Uses

When starting to use square Li-Po batteries in wholesale installment, you will encounter several common problems. One potential issue is the bulk and form factor of such batteries, often making it difficult to insert them into certain electronic gadgets. Also, square LiPo packs could come with lower capacity than cylindrical cells; hence they might not last as many cycles before needing to be charged again. There's also the question of self-discharge.  While it isn't much documented, square battery lipo battery may have a slightly higher rate of self discharge than their cylindrical cousins. This also implies that these batteries might not hold charge when you don't use them, and this isn't really desirable for wholesale like some devices might wait in warehouse or on line for months. 

What Makes Square Li-Po Battery Perfect for the Wholesale Electronics Products? 

Despite the frequently seen using issues explained over, Mitacbattery square Li-Po batteries have a number of qualities that producing them great for wholesale electronic devices. A big benefit is their form factor that can be used more efficiently in devices. Sqaure Li-Po cells can be stacked or installed in such a way that has the best use of space, perfect for an RX installation. What’s more, square Li-Po cells are generally also lighter than the cylindrical ones (good for a device that you would like to make as light and ‘carry about’-able as possible. Finally, square Li-Po cells have a better energy density than the cylindrical ones and are capable to store more energy in the same volume, so it's also a powerful and efficient solution for electronic wholesale devices. 

Is Square Li-Po Battery Safer than Cylindrical Cell? 

There are some benefits to square Li-Po batteries when it comes to safety, on the other hand, over cylindrical ones. One (relatively) easy factor is the packaging of square Li-Po cells that normally comes with a hard outer shell which protects them from punctruring or getting damaged. This reduces the chance of short circuits or fires, which are important that Specially- shaped li-po battery will becomes a safer selection for bulk electronics. What's more, they lessen the chances of puffiness or swelling as is commonly found with cylindrical cells and can cause damage to a device or its surrounding area. Generally speaking, there are safety concerns for both batteries, however square Li-Po battery tends to be safer when you require the wholesale use in which reliability as well as safety is a concern.
