  • Working principle of lithium battery for energy storage

    Working principle of lithium battery for energy storage

    Dec , 01 2023
    It consists of positive electrode, negative electrode, diaphragm and electrolyte. At present, nickel-manganese-cobalt ternary material or lithium iron phosphate is commonly used as the positive electrode of mainstream products, while the negative electrode is mostly made of graphite and other carbon materials. With the advantages of high energy density, no memory effect, fast charging and discharg...

  • Lithium battery internal resistance - AC resistance and DC resistance

    Lithium battery internal resistance - AC resistance and DC resistance

    Oct , 27 2023
    Resistance is a physical quantity that characterizes the degree of obstruction of circuit elements to current transmission. The internal resistance (internal resistance) of lithium batteries is one of the important indicators to evaluate the performance of batteries. In practical applications, the internal resistance of lithium batteries has three important roles: 1. It can be used to evaluate the...

  • Lithium battery performance key indicators - internal resistance knowledge

    Lithium battery performance key indicators - internal resistance knowledge

    Oct , 13 2023
    First, the definition and role of internal resistance (1) Definition of internal resistance Internal resistance refers to the resistance encountered by the current passing through the inside of the lithium battery during discharge or charging. It is determined by the conductivity of the material inside the battery, the ion transport rate of the electrolyte, the contact resistance between the elect...

  • Lithium-ion battery terms explained

    Lithium-ion battery terms explained

    Aug , 18 2023
    I. Battery voltage (V) 1. Open circuit voltage (OCV) The voltage of the lithium battery when it is not connected to an external circuit or load can generally be tested with a multimeter. 2. Operating voltage (WV) The potential difference between the positive and negative terminals of the battery under applied load, that is, when there is current flowing through the battery in the circuit. When the...

  • Why do lithium-ion battery plates use copper foil for the negative electrode and aluminum foil for the positive electrode

    Why do lithium-ion battery plates use copper foil for the negative electrode and aluminum foil for the positive electrode

    Aug , 09 2023
    For lithium-ion batteries, the usual positive collector is aluminum foil, and the negative collector is copper foil. In order to ensure the stability of the collector fluid inside the battery, the purity of both is required to be above 98%. With the continuous development of lithium technology, whether it is used for lithium batteries of digital products or batteries of electric vehicles, we all h...

  • How to maintain and extend UPS battery life?

    How to maintain and extend UPS battery life?

    Jul , 10 2023
    UPS batteries are used for several different things, but their main design is to ensure equipment is covered during a power failure before any backup power can kick in. It ensures that there is no lapse in power and those certain types of machinery and equipment can stay up and running without any gaps. They are often used on computers or in data centers to ensure that no valuable information...
