1. Can the laptop be used while charging? of course. Lithium batteries in laptops have no memory effect, and lithium batteries produced by regular manufacturers have a fairly complete BMS (battery management system) to control overcharging and overdischarging problems. In fact, when playing games and running large-scale programs, in order to maximize the performance of the processor, graphics card, and memory, it is actually necessary to plug in the power supply, and it will not harm the battery. 2. Can the laptop be charged all the time? In fact, in theory, it is best not to! When the laptop is plugged in, the battery does not supply power and is in an idle state, and if the lithium battery is not used for a long time, it will wear out and affect its life. It is generally recommended to charge and discharge the battery at least once a month, so that the battery power is consumed to about 20%, and then fully charged, and cycle once, instead of using automatic shutdown.

Lithium battery pack refers to the assembly and production of lithium batteries , also known as lithium battery pack . Pack refers to the customized packaging, encapsulation, and assembly of lithium batteries. The main process is divided into three parts: processing, assembly, and packaging. When several modules are jointly controlled or managed by the BMS and the thermal management system, the unified whole is called a lithium battery pack. The composition of the lithium battery pack: The structure of lithium battery pack generally includes positive electrode, negative electrode, electrolyte, diaphragm, battery case and so on. Generally, it is composed of multiple battery packs, and at the same time, a battery management system (BMS) is added, which is the final product provided by lithium battery manufacturers to users. There are two types of shell materials for lithium battery packs, including soft packs and hard packs such as aluminum shells and steel shells. Lithium...

An electrolyte is a compound that can conduct electricity when dissolved in an aqueous solution or in a molten state, and can dissociate into freely moving ions when dissolved in water or heated. The electrolyte is an important part of the lithium-ion battery , which plays the role of transporting ions and conducting current between the positive and negative electrodes. Electrolyte, as a key material of lithium-ion batteries, affects or even determines the specific energy, life, safety performance, and charge-discharge performance of the battery. As a practical electrolyte for lithium-ion batteries, the following conditions should be met: 1. Lithium ion conductivity: The electrolyte does not have electronic conductivity, but it must have good ion conductivity. In the general temperature range, the conductivity of the electrolyte is between 1×10-3~2×10-3S/cm. As an electrolyte, it must have excellent ionic conductivity and electronic insulation, allowing it to function as ...

Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries. Lithium metal battery is a battery that uses metal lithium as the negative electrode, and the matching positive electrode material can be oxygen, elemental sulfur, metal oxide and other substances; lithium ion battery does not contain metallic lithium and is rechargeable. working principle Lithium metal batteries are generally batteries that use manganese dioxide as the positive electrode material, lithium metal or its alloy metals as the negative electrode material, and use a non-aqueous electrolyte solution. Discharge reaction: Li+MnO2=LiMnO2 Lithium-ion batteries are generally batteries that use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes. The reaction that takes place at the positive electrode is LiCoO2=Li(1-x)CoO2+xLi++xe-(electron) The reaction that takes place at the negati...

Li-ion battery charging in low temperature environment has certain risks. Because with the decrease of temperature, the dynamic characteristics of graphite anode become worse and worse. During the charging process, the electrochemical polarization of the anode is significantly intensified. The precipitated metal lithium is easy to form lithium dendrites, break through the diaphragm and cause the positive and negative pole short circuit. Try to prevent lithium ion batteries from charging at low temperature. Because of the low temperature, the lithium ion battery nested on the negative electrode will appear ionic crystals, which will directly pierce the diaphragm. Generally, it will cause micro-circuit, which will affect the life and performance, and may explode seriously! According to the research of experts, the use of lithium-ion batteries in low temperature environment for a short time, or when the temperature is not low enough, will only temporarily affect the batter...

The full name of the ternary lithium-ion battery is the ternary polymer lithium battery . The ternary polymer lithium battery refers to the lithium battery whose positive electrode material uses nickel-cobalt lithium manganate (Li(NiCoMn)O2) ternary positive electrode material. The ternary composite positive electrode material Precursor products are made of nickel salt, cobalt salt, and manganese salt. The ratio of nickel, cobalt, and manganese can be adjusted according to actual needs. The battery with ternary materials as the positive electrode is safer than lithium cobalt oxide batteries. 1. Charging of ternary lithium-ion battery The highest end-of-charge voltage of a single lithium-ion battery is 4.2V, and it cannot be overcharged, otherwise the battery will be scrapped due to the loss of too much lithium ions in the positive electrode. When charging lithium-ion batteries, special constant-current and constant-voltage chargers should be used. First charge with consta...
