A battery and the four big difference between secondary battery

Source: 2020 - 03 - 25 14:08 hits: phase I, the second lithium battery is what mean? Lithium secondary battery what's the meaning of the lithium battery is divided into a cell and secondary battery. A lithium-ion battery is not rechargeable lithium battery, the second lithium battery is rechargeable lithium batteries. A civil class is mainly used in lithium-ion batteries: Shared external RAM and CMOS circuit board storage and backup power supply, memory backup power supply, clock, data backup power supply, such as all kinds of smart card meters /; Water meter, electricity meter, heat meter, gas meter, camera; Electronic measuring instrument, intelligent terminal equipment, etc. Throughout the industrial automatic instrument used in the field of instrument and equipment are: automotive electronic TPMS, oil field and oil Wells, mines, medical equipment, burglar alarm, wireless communications, maritime rescue, servers, inverter, touch screen, etc. ; Secondary lithium battery widely used in mobile phone batteries, electric vehicle batteries, electric vehicle batteries, digital camera batteries, etc. A battery and the four main difference between secondary battery structurally, secondary battery will experience in the process of discharge electrode size and the structure of the reversible change, the primary battery is much shorter, because they don't need to arrange the reversible change. Specific capacity and the quality of the individual cell specific storage volume were greater than general rechargeable batteries, but the internal resistance is much greater than the secondary battery, so the load capacity is low. Once the self-discharge of the battery self-discharge less than secondary battery. A battery can discharge time, for example, alkaline battery and carbon batteries belong to this category, secondary battery can be repeated use. Secondary battery more environmentally friendly than a battery. Batteries must be discarded after use, can be repeated use rechargeable batteries, agreed to the national standard of a new generation of rechargeable batteries are usually repeated use of more than 1000 times, also said rechargeable battery waste battery is less than 1/1000, no matter from waste reduction remains from the point of view of resource utilization, economy, the advantage of the secondary battery is very important. The first battery internal resistance for the second battery, its large current discharge function also is less than a second battery. In the case of small current, intermittent discharge, a battery quality specific capacity than the general secondary battery, but when the discharge current is greater than 800 mah, a battery can significantly reduce the capacity of the advantage. Lithium secondary battery 4 and 6 which is better 6 batteries is composed of 6 batteries, 4 battery consists of 4 batteries. In general, the damage to the battery caused by damage to a single cell, cause the entire battery scrap. A few cell natural defect rate is low. But six core battery standby time is very long. As for the good look at yourself, if you can own repairing and choose 6 core, otherwise the initiative or 4 core. In the same brand, under the condition of the same capacity, I think it is best to have four batteries, because a lot of damage to the battery is caused by damage to the whole cell fragments of a single cell. A few cell natural defect rate is low. But the quality of the battery cannot be simply measured by the number of cells, to look at the brand quality of battery and other factors.
