Common types of laptop batteries

See if you really understand? The laptop battery is becoming more and more thinner and lighter, and the battery as a power source is also undergoing serious changes. The traditional 18650 battery is limited by its fixed physical standards, and it is now difficult to put it on a portable notebook computer. It is replaced by a more flexible polymer battery. However, the battery life of a laptop is also directly related to daily use and maintenance. Do you really know your laptop battery? Today, I will talk to you about laptop batteries. Common types of laptop batteries Today, the two most widely used lithium polymers in laptop computers are lithium batteries. Now that we have discussed batteries, let's briefly compare the two batteries first. In terms of product shape, the electrolyte of ordinary lithium batteries is liquid, mainly cylindrical. The shape and size are slightly larger than no. 5Battery. The shell is mainly made of alloy or stainless steel. The electrolyte of lithium polymer battery is solid, Shell is more flexible, the packaging plan, the battery shape is rectangular, and the volume, the standard does not have a fixed binding, and it is more fluid than lithium batteries. This is an important reason for more and more Laptop lithium polymer battery. From the perspective of battery capacity, the ordinary 18650 lithium battery has a single capacity of 2600-3200mAh, while the lithium polymer battery has a larger capacity than a lithium battery under the same volume, and has more advantages than a lithium battery. From a safety point of view, the biggest safety problem of lithium batteries lies in internal short circuits. The electrolyte of lithium polymer batteries is closer to a solid state (mostly in a gel state), while the electrolyte of lithium batteries is liquid. From a physical point of view, the safety of lithium polymer batteries is higher than that of lithium batteries. However, with the advancement of battery processing technology, no matter which battery base is selected, there will be no vicious danger such as explosion. 1. Advantages of lithium polymer battery: high plasticity, high volume utilization, high capacity density, high safety. Tailwind: relatively high cost 2. Advantages of lithium battery: relatively low cost. Downwind: low capacity utilization. Current notebook battery planning Method 1. Removable (the base is lithium ion 18650) 2. Not removable (the base material is polymer) 3. It cannot be separated, but there is a physical switch for the battery.
