  • How Lithium-ion Batteries Work

    How Lithium-ion Batteries Work

    Mar , 23 2023
    Lithium-ion batteries are popular because they have a number of important advantages over competing technologies: They're generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its at...

  • What are the factors that are unfavorable to lead-acid batteries?

    What are the factors that are unfavorable to lead-acid batteries?

    Apr , 15 2023
    There are many factors that are unfavorable to the battery, mainly in the charging and discharging phase. (1). The "second super" discharge stage is mainly the discharge current overvalue, that is, the discharge exceeds the allowable current value for a long time; the second problem of discharge is over-discharge, that is, exceeding the allowable discharge capacity of the battery, which is called ...

  • Three-stage charging of lead-acid battery

    Three-stage charging of lead-acid battery

    Apr , 15 2023
    1. What is the three-stage charging of lead-acid batteries? The charging method of lead-acid batteries should be divided into three stages, namely: constant current charging - constant voltage charging - trickle charging. Constant current charging stage: charge to 13.4V with 0.2C10 A current. Constant voltage charging stage: 2.4V/cell, charging time 3h, cut-off current 0.02C10A Trickle charge phas...

  • What are the reasons for the sulfation of lead-acid battery plates?

    What are the reasons for the sulfation of lead-acid battery plates?

    Apr , 15 2023
    The reasons for plate sulfation are as follows: 1) The initial charging of the battery is insufficient or the initial charging interruption time is long; 2) The battery is insufficiently charged for a long time; 3) Failure to charge in time after discharge; 4) Frequent overcharging or low current deep discharge; 5) If the density of the electrolyte is too high or the temperature is too high, lead ...

  • Damage of lithium battery caused by overcharge and discharge

    Damage of lithium battery caused by overcharge and discharge

    Apr , 24 2023
    The cathode materials of lithium-ion batteries are usually composed of active compounds of lithium, while the negative electrodes are carbon with special molecular structure. The main components of the common cathode materials are licoo2/LiFePO4, etc. When charging, the potential added to the battery poles forces the positive compounds to release lithium ions and embed the anode molecules into the...

    Charge and discharge theory and calculation method design of lithium battery

    May , 13 2023
    1 . Production of lithium Ion battery 1 .1 State Of Charge ( state-of-charge; S OC) Soc can be defined as the state of available electrical energy in the battery, usually expressed as a percentage. Because the available electric energy varies with charging and discharging current, temperature, and aging phenomenon, the definition Of the State of Charge is also divided into two types: Absolute stat...
