Show you are understanding and correct use of lithium battery

Source: 2020 - 04 - 10 20:58 hits: error - in lithium battery Correct understanding and use of lithium battery now, mobile phone penetration rate is higher and higher, for charging the mobile phone is everyone must do homework every day. But do you know the characteristics of your cell phone battery? They should be how to use, storage and charge? You know, there are some specious, tend to be misleading. Let's start from the characteristics of mobile phone battery. The flexible polymer lithium ion battery has been widely used in mobile phones. Lithium-ion batteries for its excellent performance, widely used in mobile phones, cameras, laptops, cordless phones, power tools, electric toys, remote control or cameras and other portable electronic devices. Lithium battery type lithium ion battery cathode is graphite crystals, the anode is usually lithium oxide. When charging, lithium ions to move from the positive to the negative terminal, and embedded in the graphite layers. In the process of discharge, the lithium ions from the negative electrode of graphite crystal surface from and move to the anode. Lithium in battery charge and discharge process, therefore, always take the form of lithium ion, rather than take the form of metal lithium. This is why they are referred to as lithium ion batteries, or lithium ion batteries. Lithium battery has small volume, large capacity, light weight, no pollution, the unit high voltage, low self-discharge rate, cell cycle more advantages, but the price is more expensive. Nickel cadmium battery capacity is small, self-discharge, serious environment pollution is serious, is being phased out. Nickel metal hydride battery performance than high, polluting the environment, but only 1 single voltage. 2 v, use scope is limited, so we often use no. The battery is nickel metal hydride batteries. Lithium battery characteristics has high weight can ratio and volume ratio; High voltage, single lithium battery voltage is 3. 6 v, the equivalent of three nickel cadmium or nickel metal hydride rechargeable batteries in series voltage. Does small self-discharge, can store a long time, this is the most prominent advantages of battery; No memory effect, lithium battery no nickel cadmium battery memory effect, so the lithium battery before charging does not need to discharge, Life is long, under normal working conditions, lithium battery charge and discharge cycles is far more than 500 times; It can be quick charge. Lithium battery can generally be according to the current capacity of 0. 5 ~ 1 times charging, the charging time to 1 ~ 2 hours. Does can be used in parallel; Does the battery does not contain heavy metals such as cadmium, lead, mercury, on the environment pollution-free, green battery is the most advanced modern. Does the cost is high, compared with other rechargeable batteries, lithium batteries are more expensive. The internal structure of lithium-ion battery lithium battery there are generally two kinds of shapes: cylindrical and rectangular. Battery is internal spiral winding, there is a very fine between the positive and negative and high permeability of polyethylene film isolation material. The positive electrode including composed of lithium cobalt and lithium ion collector and current collector composed of aluminum film. The cathode of carbon material of lithium ion collector and the copper film made of current collector. Battery charging with organic electrolyte solution. Also provides relief valve and PTC element, in order to protect the battery in exceptional cases, and output short circuit from being damaged. A single lithium battery voltage is 3. 6 v, volume could not be infinite. As a result, a single lithium-ion battery is often series parallel processing, to meet the needs of different occasions.
