Lithium battery charge for the first time what are basic myth?

Source: 2020 - 03 - 29 16:15 hits: first lithium battery charge for the first time what are the basic error of error 1: charging for the first time, need to activate the cell phone battery? First of all, this sentence itself is a problem, imagine that you bought a mobile phone, mobile power supply is not active, so why do you want to buy these have the power? That's because the test is activated before they go out. So there's no need to activate. In fact, 'the first three time charge 12 hours' this sentence is obviously early nickel battery ( Such as nickel cadmium and nickel metal hydride) The last. Modern industry has turned to the lithium ion battery, it has very different characteristics with nickel battery. So you only need to recharge it, and then pull the plug as usual. Early nickel cadmium rechargeable battery and nickel metal hydride rechargeable batteries, these batteries can attack the phenomenon known as the 'memory effect', in not completely discharge the status of the charging, the battery overcharge, long-term causes hyperplasia of crystal plate electrode, blocking the electrolyte and electrode contact, cause the battery voltage to drop, let users against the battery soon ran out. Myth 2: the battery need to use the to charge? Charging excessive can cause battery burst? Lithium ion battery has a large energy density, high voltage ( Separate premorbid lithium ion battery voltage can reach 4. 2 V, and ordinary nickel-based rechargeable battery is 1. 2 V) , and low voltage batteries, lithium ion battery electrodes REDOX reaction is very serious, so the use of lithium ion battery conditions must be strictly limited, charging excessive, excessive discharge and short circuit, high temperature will lead to cell damage, even fire and explosion. In practice, however, the lithium ion battery will multiple battery encapsulation in a panel, and a set of security maintenance circuit and various safety devices. These safety design to ensure the battery circuit in the event of overcharge, discharge and short circuit when the automatic blocking; The battery internal pressure is too large, also can trigger exhaust extract; Overheated batteries will trigger hot melt device maintenance, stop the lithium ions move, then stop the electrochemical reaction of the battery. Therefore, as long as you don't use quality is not reliable to counterfeit batteries, cell phone charge not unplug plug don't cause battery burst in a timely manner. Myth 3: can charge the battery by reducing the number of batteries, extend battery life? Digital equipment manufacturers will charge can charge hundreds of times, in fact, this is detected in depth discharge environment, that is, the battery is fully charged, and then charging, the cycle, continuous deep discharge the battery.
