Because of the different processing methods, lithium ion batteries are divided into wound lithium ion batteries and laminated lithium ion batteries. They have different principles and have the same performance. Then what is the difference between the lithium ion batteries produced by these two methods? Which is better? A) Detailed explanation of the two produce processes Wound lithium battery A battery composed of cells formed by a combination of winding methods is called a wound battery. Wound batteries are also called cells, and those in the battery industry are called winding cell. Laminated lithium battery Power batteries are generally divided into three forms: square shell, soft pack, and cylindrical. They mostly adopt two processes of winding and lamination, which have their own advantages and disadvantages. Lamination batteries are lithium batteries for vehicles that use lamination technology. The working principle of the laminated battery is the same as that of

Many people are elusive about newly-purchased lithium batteries. The author summarized 10 tips on how to use lithium batteries, and share them with you, hoping to help. 1. How to use the newly purchased lithium battery? Should it be charged or discharged first? How to charge and discharge? In fact, most of the current lithium batteries are polymer lithium batteries , and there is no such thing as how long the battery needs to be recharged for activation as the previous lithium battery manufacturers said. After we buy it back, it can be used normally. First discharge with a small current (usually set to 1-2A), and then use 1A current for charge and discharge cycles for 2-3 times. 2. The new battery has just started to use, the voltage is unbalanced, and after charging and discharging several times, it is normal again. What is the problem? The main reason is that although the individual cells in the battery pack are well-matched, there are still individual differences in

The quality of the charger directly determines the length of the life of the lithium-ion battery, so it is very important to choose a good quality charger. The output voltage of the charger must be matched according to your battery. So how to choose a good quality lithium-ion battery charger? 1. Look at the charging speed of the charger Common chargers use constant current charging, and the charging speed is mainly related to the current supplied by the charger. The greater the charging current, the faster the charging speed. The charging time is not only related to the charging speed, but also depends on the capacity of the lithium-ion battery. It should be noted that the higher the charging current, the higher the quality requirements for the internal system design of chargers and lithium-ion batteries . In general, the higher the charging current, the more heat that may be caused during the charging process, and the greater the damage to the performance of the batte

I believe that most consumers have heard that the life of a lithium battery is "500 times", 500 times of charge and discharge, beyond this number, the battery will "end of life", many friends in order to be able to extend the battery life, every time The battery is charged only when it is completely exhausted. Does this really extend the life of the battery? the answer is negative. The life of a lithium battery is "500 times", which does not refer to the number of times of charging, but a cycle of charging and discharging. The so-called 500 times means that the manufacturer has achieved about 625 charging cycles at a constant depth of discharge (such as 80%), reaching 500 charging cycles. (80%*625=500) (Ignore factors such as reduction of lithium battery capacity) However, due to various influences in real life, especially the depth of discharge during charging is not constant, "500 charging cycles" can only be used as a referenc

The use of chargers allows many electronic devices to operate normally. Without chargers, our lives will be troubled to a certain extent. In order to enhance everyone's understanding of the charger, this article will introduce the wireless charger related content, mainly to analyze whether the wireless charger is harmful to the mobile phone and explain the precautions of the wireless charger. If you are interested in chargers, you might as well continue reading. Is the wireless charger harmful to mobile phones? The wireless charger will not harm the mobile phone under normal circumstances. The current working frequency of wireless charging is below 1M, so it will not affect the signal of the mobile phone. Wireless charging has no effect on the battery life of mobile phones. It is basically the same as wired charging, but the rate is lower, but the conversion rate of wireless chargers is still very high, which saves more energy. Wireless chargers mainly use inducti

Generally, a 3.7V lithium battery needs to have a "protection circuit board" for overcharging and overdischarging. If the battery does not have a protection circuit board, it can only be charged with a voltage of about 4.2V, because the ideal full charge voltage of a lithium battery is 4.2V. If the voltage is exceed 4.2V,  the battery may is damaged, it is necessary to monitor the condition of the battery at the same time when charging with this method. With the protection circuit board, you can use 5V to charge (4.8V to 5.2V can be used), the USB 5V charger of the computer or the 5V charger of the mobile phone can be used. 3.7V battery, charge cut-off voltage 4.2V, discharge cut-off voltage is 3.0V. Therefore, when the open circuit voltage of the battery is lower than 3.6V, it should be able to charge. It is best to use 4.2V constant voltage charging mode, you don't need to pay attention to the charging time. Charging with 5V is prone to danger of over
