Can the laptop be charged all the time?
Monday, April 10, 2023 7:54:26 PM America/Los_Angeles
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.

Friday, February 17, 2023 2:09:53 AM America/Los_Angeles
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.

Monday, October 17, 2022 7:52:33 PM America/Los_Angeles
Lithium battery separator is one of the key inner layer components of lithium battery. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery.

Tuesday, September 13, 2022 8:29:34 PM America/Los_Angeles
As one of the current battery types for electric vehicles, LiFePO4 batteries are characterized by relatively stable thermal stability, low production costs, and long service life. However, its low temperature resistance is very low. In the case of -10 ℃, although the battery can be used normally, the charging efficiency will be greatly reduced.
What is the voltage range of LiFePO4 battery?
Sunday, July 24, 2022 2:05:38 AM America/Los_Angeles
LiFePO4 battery is one of the Lithium battery, Because the cathode materials of LiFePO4 batteries are mainly compounds of phosphorus, acid, iron and lithium. Generally speaking, the voltage range of LiFePO4 battery is basically between 3.2V-3.6V. Among them, the nominal voltage is 3.2V, and the high-level termination charging voltage is 3.6V. However, the positive and negative materials, electrolytes, and production processes used by various manufacturers are different, so there will be differences in performance.

Thursday, July 14, 2022 8:07:25 PM America/Los_Angeles
Lithium manganate battery refers to a battery whose positive electrode uses lithium manganate material. The nominal voltage of lithium manganate battery is 2.5~4.2v. Lithium manganate battery is widely used because of its low cost and good safety. Lithium manganate battery is a cathode material with low cost, good safety and low temperature performance, but the material itself is not very stable, and it is easy to decompose to generate gas, so it is mostly used in combination with other materials to reduce the cost of the cell, but its cycle The lifespan decays rapidly, bulging easily occurs, the high temperature performance is poor, and the lifespan is relatively short. It is mainly used for large and medium-sized batteries. In terms of power batteries, its nominal voltage is 3.7V.
