    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 ...

    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...

    How a UPS system works with a Generator

    Sep , 19 2022
    As weather extremes and storms increase, power outages are likely to continue to rise. According to the U.S. Energy Information Administration, U.S. customers experienced an average of nearly six hours of power interruptions in 2018. If you have invested in a generator, you’ve prepared for when a storm hits, right? Almost. Even with a generator, you still need a battery backup, also known as an Un...

    Key Factors in Choosing the Right UPS

    Sep , 26 2022
    You rely on your UPS system for backup if your power goes out, right? But does your UPS have your back? That is, will it provide a bridge of power long enough for what you need? At the very least you will want to save your data and perform a safe shutdown. Your UPS backup battery will only provide power for a set amount of time, known as runtime. In this article, we will provide a step-by-step app...

    What is open circuit voltage and what is the capacity of a battery?

    Oct , 17 2022
    What is the nominal voltage? The nominal voltage of the battery refers to the voltage displayed during normal operation. The nominal voltage of the secondary nickel-cadmium nickel-hydrogen battery is 1.2V; the nominal voltage of the secondary lithium battery is 3.6V. What is open circuit voltage? The open circuit voltage refers to the potential difference between the positive and negative electrod...

    Advantages of combining solar and energy storage

    Nov , 08 2022
    Grid stability, battery safety and blackout prevention Solar-storage solutions can act as sunshine insurance, allowing stored power to be dispensed when power demand is high (and accompanied by higher prices) and solar generation is low. Aided by these smart technologies, unified solar and storage can also help prevent blackouts, an issue seen from Australia to California, Lebanon to South Africa....

    How a Modular UPS can help the Data Centers to scale their Operations?

    Dec , 30 2022
    Data center densities continue to increase, and so does the demand for data. The global data center market is expected to grow at a CAGR of 4.5% over the next five years. With floor space at a premium, colocation providers and data center managers are challenged to expand operational capacity to add power without adding physical space or scheduling downtime. At the same time, d...

  • How does an uninterruptible power supply work?

    How does an uninterruptible power supply work?

    Jan , 11 2023
    What your computer expects to get from the power grid is 120/127/208/220/230/240-volt AC power oscillating at 50/60 Hertz. A computer can tolerate slight differences from this specification, but a significant deviation will cause the computer's power supply to fail. An uninterruptible power supply generally protects a computer against four different power problems: 1- Voltage surges and spikes - T...
