Tips for life: use lithium batteries correctly

Tips for life: Correct use of lithium batteries. Many people are afraid of lithium batteries, but they can't do anything about it. The helplessness is because mobile phones, notebooks, tablets and other devices want to use it, and the fear is because I don’t know when the lithium battery will suddenly make a terrorist attack in front of me: either burning or exploding. This kind of thing is temporary, and is naturally related to the electrical characteristics and quality of the lithium battery itself, but it is not ruled out that whether the lithium battery is used correctly is also one of the reasons for the failure of the lithium battery. The problem of the correct use of lithium batteries The method is based on the characteristics of the lithium battery itself. Therefore, we first analyze the causes of explosion or combustion of lithium batteries from an electrical point of view. Combustion or blasting is generally due to the accumulation of heat without spreading out, and it will only occur when it accumulates to the ignition point, or when the heat reaches a certain level in a certain space. As a battery, in summary, there are generally no four reasons for the attack in the above situation. 1. Internal short circuit (mostly large soft bag monomers): structure or process defects lead to the insertion of tabs, too little diaphragm packing, burrs, diaphragm discounts, etc. The battery lug insertion usually appears in thick and parallel structures. The lug insulation is not in place. In the subsequent products and simple maintenance board or use process, it will cause an acute internal short circuit, and then burn or blast (internal short circuit: this person has a deep Relevant experience, and then waste batteries, the practice of 2k or more is due to design defects, the nature of the abnormality is: but the current situation is very few, unless external force factors. 2. External short circuit: The incineration caused by the external short circuit of the battery below 1AH rarely occurs after the explosion , Generally manifested as swelling or smoldering of the tab ears. I analyzed the incineration caused by external short-circuits of power lithium-ion batteries or large-capacity mobile phone batteries. Involving customers using improper metal casing installations, the electrode ear insulation was not considered, and the battery smoke incineration at the installation site Abnormal; power lithium-ion batteries are also very common in the absence of structural fixation measures (not thoughtful). In this case, the external insulation maintenance film or cable sheath of the battery will be damaged when the user uses the battery pack to shake , Resulting in short-circuit burning. 3. Overcharge and discharge: This is the most dangerous and the most fearful of the company’s emergence, but it will occasionally appear. According to my understanding, there are two points: a. The user does not use the matching charging as required Then the repair line is damaged, and users usually charge the charger in an unlimited time. It is difficult not to explode. B. The battery configuration is unreasonable, and the repair board failure will also cause the explosion of miasma. The battery is also 4. The material of the battery is not up to the standard. The material is not up to standard, and the voltage and current may be overheated during calibration, and then malfunction. Based on the above analysis, if the lithium battery can be used correctly, try to prevent the occurrence of the above situation, and you can find some methods 1. Frequent deep charging and discharging: Lithium batteries have no memory. Many friends are using lithium batteries or digital products lithium batteries. They have no power to use (maintenance board repair). Then, in the eyes of many people, this is also a way to activate Batteries. In the use of lithium batteries, we call the state of charge as deep charging and discharging. In fact, deep charging and discharging is an important mistake for many people in using lithium batteries. Scientists have concluded through experiments that the number of deep charging and discharging Under other stable environmental conditions, repeated charging and discharging are proportional to the battery life, which will cause the battery life to end prematurely. The longer-life lithium battery is prone to battery swelling at the end of use, which will cause an explosion. 2 Overcharging and The design of the maintenance board with high charge and discharge conditions is unreasonable, and the charging time is often attacked. We are often full of love and then charge the battery of the device for a period of time. This can make the resistance torque of our device longer, but many people don't know it. Charging and discharging conditions for a long time will create serious damage to the performance and damage of a lithium battery, which will cause serious damage to the lithium battery. Under extreme conditions such as blasting, the battery is full of such good things. If you keep plugging in the charger, sooner or later it will become a tragedy. 3. The charging and discharging time should also control the current of the charger and the current load of general electrical appliances within the specified range. Excessive current load can easily cause internal short circuit of the battery, which will damage the lithium ion and cause hidden circuit safety hazards. The voltage is the same. So when we use the charger Also pay attention to whether the charger is qualified. 4. Operating environment. Lithium batteries are extremely sensitive to temperature. If they are used for a long time below the freezing point, they may have a great impact on battery life and damage. And in a long-term overheating environment, it will greatly reduce the life of the battery. The serious problem is caused by the new blasting of the internal pressure. Even if there is no blast, the battery will be quickly cancelled at a high temperature. It feels that there are some cases due to the blasting of the pool. And unfortunately, most of the reasons are due to the high temperature of its operating environment. After experiencing many difficulties, the manufacturer has finally moved. Now most manufacturers have added maintenance equipment, special electronic digital product repair or multiple repairs, and added two new layers. In order to prevent attacks in this situation, however, users themselves strengthen Awareness is still very important.
