What are the misconceptions about the lithium battery?

Source: 2020 - 03 - 25 20:50 hits: lithium battery has the mistake? New battery needs to be repeatedly charging and discharging to activate? There has been some rechargeable batteries need to be similar to 'activate' work. These are early nickel cadmium rechargeable battery and nickel metal hydride rechargeable battery. These batteries will happen this phenomenon is called 'memory effect', under the condition of incomplete discharge, just do a battery overcharge, time grew to magic hyperplasia crystal plate electrode, blocking the electrolyte and electrode contact plate, the battery voltage drops, let users think the battery soon ran out. Therefore, for the two batteries [ 1] On a regular basis ( Not every time) After discharge the battery to charge can reduce the causes of voltage drop. However, most used in mobile phones and laptop battery is lithium ion battery. Lithium ion batteries are becoming more and more common, of course, because of their small size, but can store a lot of energy. Lithium ion battery at the beginning of the operation does not need to be intermittently activated by depth charge and discharge, because the battery of initialization and testing process is completed in battery production. Lithium-ion batteries also does not have the so-called 'memory effect, can charge at any time. ( 2] Chinese English learning network think lithium ion batteries should be in a separate light interval charging and discharging claim regularly, just for the calibration of charge on the notebook computer and some high-end smartphones testing equipment, rather than because of any benefit to the battery itself. ( 3] About general mobile phones, digital cameras and other segments of the battery on the power of the equipment, it is not need on a regular basis and free of charge and discharge. What? Some have the phone book, right? You should know, cell phone batteries are often not made by the consumer mobile phone maker. Explanation of the book is likely to be alert users to test battery, see if you have any questions. In addition, because of the nickel cadmium battery and nickel metal hydride batteries do need activation, specification of this formula can also be based on the copy of the template. Charging excessive can cause battery burst? Lithium ion battery has a large energy density, high voltage ( A single lithium-ion battery voltage is 4. 2 V, and general nickel-based rechargeable battery is 1. 2 V) , and the low voltage grade compared with batteries, lithium ion battery electrodes oxidation rehabilitation is very strong, so the use of the lithium ion battery requirements strictly limited, overcharge, excessive discharge, short circuit, such as high temperature can make the damage to the battery, and a fire exploded again. However, theoretically, lithium ion battery is composed of several cells, a set of protection circuit and all kinds of safety equipment, and encapsulated in a panel. ( 5] These security scheme can guarantee the battery during overcharge, over discharge, short circuit circuit is cut off; The battery internal pressure is too large, also can trigger exhaust system reduce stress; High battery temperature can trigger hot melt protection device, prevent lithium ions move, and interrupt the electrochemical reaction of the battery. Therefore, as long as you don't use quality unreliable counterfeit batteries, cell phone charged and not remove the plug will not lead to battery burst in a timely manner. Can decrease The Times of charging and extend battery life? The typical life of lithium ion battery can reach hundreds of times to charge and discharge cycle, this is often mentioned in the relevant cells and equipment specifications. Charge and discharge cycle is drained battery and charge process, rather than the battery in them out again. Continuous intermittent depth of the lithium ion battery charge and discharge to the life of lithium ion batteries. Data from more than hundreds of times is also measured in such conditions. However, in the case of daily shallow shallow filling, the service life of lithium ion battery is actually quite long. In addition, the lithium ion battery in the case of without the use of lose capacity, voltage and temperature is the main influence factors. Studies have shown that the de-energized state lithium ion in the long run, its capacity will produce significant loss. Similarly, the higher the temperature, speed of the lithium ion battery capacity loss is faster, and the loss is not reversible, which means the battery capacity will always smaller. Under zero degree, the remaining 40% of the lithium ion battery will lose 2% of capacity in a year. At 40 degrees, lithium ion batteries are fully charged 35% loss
