  • Power Factor and Harmonic Analysis in PWM converter

    Power Factor and Harmonic Analysis in PWM converter

    Aug , 15 2022
    Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part of most of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC to DC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is use...

  • Improving Access to Forklift Battery Chargers

    Improving Access to Forklift Battery Chargers

    Aug , 15 2022
    Is the design of your battery room holding your operation back? As valuable as battery room space can be, you need to make sure toprotect access to battery chargers and other crucial equipment when planning your layout. Crowded battery rooms detract significantly from operational efficiency by placing obstacles between workers and the equipment in need of standard maintenance. If a battery charger...

  • SEI film formation mechanism

    SEI film formation mechanism

    Sep , 05 2022
    During the formation of the SEI film, various reduction reactions are carried out by the electrolyte solvent, lithium salt, additives, and trace air impurities. This series of reactions is not only affected by the inherent properties of substances such as reduction potential, reduction activation energy, and exchange current density, but also by other factors such as temperature, electrolyte salt ...

  • Effect of electrolyte on SEI film

    Effect of electrolyte on SEI film

    Sep , 05 2022
    The electrolyte is the main source of the reduction reaction reactants for the formation of the SEI film , and both the electrolyte solvent and the lithium salt will affect the composition of the SEI film. When the main components of the electrolyte are basically fixed, the performance of the SEI membrane can only be improved by other means. The researchers found that the formation of the SEI film...

  • Influence of SEI film on the performance of Li-ion battery

    Influence of SEI film on the performance of Li-ion battery

    Sep , 05 2022
    After extensive research, it has been found that the properties of SEI films greatly affect the performance of Li-ion batteries. During the formation process, the amount of the SEI film formed represents the amount of lithium in the consumed lithium-ion battery, which directly determines the capacity of the lithium- ion battery. Therefore, in the process of forming the SEI film, the less lithium i...

  • Overview of the lithium battery formation process

    Overview of the lithium battery formation process

    Sep , 05 2022
    Lithium- ion battery formation process includes constant current, constant voltage and intelligent charging. The polarization phenomenon of constant current charging is serious, and its initial current is low, the current at the end of charging is high, the charging time is long, the energy waste is serious, and the battery life will be reduced. During constant voltage charging, the current is rel...

  • Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

    Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

    Sep , 05 2022
    1. Energy density: The energy density of ternary lithium is about 1.7 times that of lithium iron phosphate, so the volume and weight of ternary lithium batteries will be smaller than those of lithium iron phosphate batteries, and the car load will be smaller. 2. Safety performance: lithium iron phosphate battery will perform better in acupuncture test, and in high temperature environment, the stab...

    Effect of formation current density on battery performance

    Sep , 13 2022
    When graphite is used as the negative electrode active material, there are two types of reactions for the formation of SEI films: two-electron reactions, that is, two electrons participate in the reaction at the same time, and it is easier to generate inorganic lithium salt components; single-electron reactions, that is, only need A reaction that can take place when one electron participates, it i...

    Failure causes of lithium battery- Failure during shelving

    Oct , 08 2022
    In the service life of the power battery, most of the time is in a state of shelving. Generally, after a long period of shelving, the performance of the battery will decline, generally showing an increase in internal resistance, a decrease in voltage, and a decrease in discharge capacity. There are many factors that cause the degradation of battery performance, among which temperature, state of ch...
