Due to the process limitations of welding multipole ears in cylindrical batteries, the rate characteristics are slightly inferior to those of square multipole ear batteries.
In order to ensure the safe and reliable use of lithium-ion batteries, experts have conducted very strict and meticulous battery safety design du
Nowadays, most mobile devices and cameras use lithium battery packs, and most consumers do not understand the capacity labels on these battery labels, such as mAh and Wh,
The standard charging and discharging voltage range for 3.2V lithium iron phosphate batteries is 2.0-3.8V, with a positive electrode specific capacity of 125mAH/g.
The 18650 lithium battery is a very common type of lithium battery, and the battery cells for laptops are derived from 18650. We have found that sometimes 18650 lithium batteries cannot charge properly during use. Let's analyze the reasons below.
The basic structure of a lithium battery consists of four parts: the battery cell, the protective plate, the outer shell, and the leads/terminals.
Internal short circuit: Structural or process defects leading to excessive insertion of the terminal ear, insufficient membrane wrapping, burrs, membrane breakage, etc.
18650 is currently the most mature power battery product, and without safety, there can be no maturity... Maturity also means safety, efficiency, low cost, high consistency, and high reliability. "
