22 Years' Battery Customization

Most of today's portable electronic devices, including laptops, smartphones, tablets, e-book readers, and fitness trackers, use lithium-ion batteries. The compact battery is not bad. The energy density is high, the self-discharge is low, and the memory effect is very low. All functions are ideal for recording ranges from MacBook to Kindles.
Unfortunately, there is no free lunch, and all these benefits of high energy density come at a price. Lithium-ion batteries are less stable compared to their predecessor. Lithium is more reactive than previously used compounds, the battery has a very small barrier between the cell and the outer layer, and the entire battery is under load.
If a lithium-ion battery becomes too hot, too expensive, or becomes damaged over time, the internal cells of the battery may release a flammable electrolyte mixture. Hence the extended battery effect. The battery is designed as a safety measure that releases gas to prevent catastrophic fires.
Battery expansion is a failure mode associated with a type of battery cell technology known as a lithium-ion polymer. Lithium-ion polymer batteries have gained popularity in the industry in recent years for their slim, unique form factor and long lifespan. Lithium-ion polymer batteries are housed in flexible multilayer bags that can expand for a variety of reasons, including but not limited to life, use, and environmental conditions.
On the other hand, older industrial notebook models used cylindrical lithium-ion batteries with a metal casing without expansion. While the risk of battery swelling is small, it is associated with lithium-ion polymer cell technology widely used in the technology industry. This problem affects the entire industry and all laptop manufacturers.
Swollen batteries can interfere with laptop performance and in some cases damage the product's chassis. If a swollen battery in a Dell product is not a safety concern, a swollen battery should be replaced as soon as it is found. Again, it's important to always buy genuine Dell replacement batteries.

Lithium-ion batteries use chemical reactions to generate energy. As the battery ages, these chemical reactions stop completing, causing the formation of gases (called gas evolution) that can cause the battery to expand. Also, if the inner layers of the battery are not properly separated (due to damage or defects), gas evolution, swelling, and even fire can occur.
Swelling is the result of particles falling between the layers of the battery and eventually penetrating the membrane separating these layers. When the membrane is damaged, water vapor in the air can react with the cells, causing them to expand. This explosive reaction has confused the Samsung Galaxy Note 7 and the hoverboard, so the transportation of batteries and transportation of aircraft is severely restricted.
As the battery expands, it expands and pushes other components out. Often the display, buttons, or trackpad will move out of their normal orientation. If your phone case doesn't fit your old one, there are new gaps between components, buttons are harder or harder to press, or the device offers more than usual and feels “slick,” the battery may swell.

Either way, you are facing an epidemic of modern inflatable lithium-ion battery technology. This may sound like an interesting error, but it is very dangerous. Lithium-ion batteries are volatile and are used in most technological devices today.
Lithium-ion batteries have several important advantages over other chemistries. Lithium-ion batteries have a very high energy density and can store large amounts of electricity in relatively small and bright rooms.
The battery has a very long lifespan and durability, so it can be charged and discharged hundreds of times before it loses its effectiveness. The battery is cheap and easy to charge with a modern charger that can charge significantly faster than other types of batteries. With less self-discharge, a charged battery can last sometime between uses without losing much energy.
Lithium-ion batteries are sensitive to high temperatures and cannot be charged at high voltages. The battery performs well in low temperatures, but it cannot be charged quickly without serious damage.
Do Not Charge or Use the Device
If you find a swollen or damaged battery, you should stop using the device immediately. Turn off your device and most importantly, do not charge it. When the battery reaches the point of failure and the battery swells, it should be assumed that all safety mechanisms in the battery are disabled. Charging an inflated battery turns into a balloon of dangerous flammable gas exploding in your living room.
How to Prevent Swollen Batteries
You may have read the previous section, but you might be thinking, "I don't have a swollen battery right now, but I don't want a battery in the future." In your case, the goal is to keep the battery comfortable and prevent premature damage to the battery.
Keep Your Batteries Cool
Lithium-ion batteries hate heat. It can be impossible to keep cool all the time, but it's best not to leave electronics on the grill. Do not leave your laptop in the car on hot days. Do not leave your phone on a kitchen counter in the midday sun or do anything to cool the battery.
If you are not using a replacement lithium-ion device or device, store it in a cool, dry place at home.
