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. "
Generally speaking, 18650 lithium battery packs have the following benefits.
Characteristics of lithium-ion power batteries
After using up all your batteries, take them off and treat them with temperature. In unstable temperature conditions, batteries will greatly shorten their usage time because they
