• How much do you know about battery terminology?

    As a leading company specializing in battery production, we understand the vital role batteries play in modern society. To deepen everyone’s understanding of batteries, we’ve compiled some professional battery terminology, aiming to be helpful to all. Let’s dive in! Battery: A power supply device consisting of one or more electrochemical cells with external connections, used to power electrical equipment. Battery cell: Refers to a single component containing positive and negative electrodes and other necessary electrochemical and structural components. A battery cell is an independent energy conversion device delivering electrical energy to an external circuit through a controlled internal chemical process. This conversion involves the transfer of ions between electrodes with different potentials. Primary cell: Also known as a disposable battery, this battery can only be discharged once. Once all the chemical substances inside have reacted, it can no longer provide electrical energy or store externally supplied electricity, rendering it unusable…

  • Exploring the Cycle Life and influential factors of LiFePO4 Batteries

    Renowned for their exceptional performance and durability, lithium iron phosphate (LiFePO4) batteries have emerged as a frontrunner in battery technology. It is crucial to comprehend the cycle life of LiFePO4 batteries and the variables that impact their longevity when procuring and utilizing them. This article delves into an in-depth examination of the cycle life of LiFePO4 batteries and the myriad factors that influence their lifespan. Cycle life denotes the number of complete charge and discharge cycles a battery can undergo while maintaining its rated capacity. Essentially, it gauges the rate of battery degradation over time, offering a more accurate assessment of its lifespan than mere years alone. The cycle life of lithium iron phosphate batteries is intricately linked with the depth of discharge (DoD), representing the extent to which the battery is discharged. For instance, Taking PLB’s IFR26650-30B battery as an example : a battery’s cycle life at 100% DoD…

  • Why do lithium batteries require higher temperatures to charge than to discharge?

    Lithium batteries exhibit a wider temperature range for discharge (-20°C to 60°C) compared to charging (0°C to 45°C), a fact commonly noted in lithium battery data sheets across various brands and models. This prompts the question: Why do lithium batteries necessitate higher temperatures during charging? The rationale lies in the phenomenon of “lithium plating,” which occurs at temperatures below 0°C during the charging process. This is primarily attributed to diminished molecular mobility under low-temperature conditions. Notably, lithium-ion in graphite is inhibited, resulting in a decrease in the intercalation rate and a lithium plating reaction on the graphite surface. Consequently, this process elevates internal resistance and results in capacity loss within the lithium battery. To grasp the chemistry underlying the lithium plating reaction, understanding the operational mechanism of lithium batteries is imperative. These batteries store and discharge energy by facilitating the migration of lithium ions between positive and negative electrodes. During…

  • What does the‘U’mean in the 1U/2U rack-mounted UPS battery?

    When purchasing rack-mounted UPS batteries, the buyers often mention professional terms such as 1U and 2U. What does‘U’mean? The ‘U’ stands for unit, which represents the external dimensions of the server. The size is determined by the Electronic Industry Agreement (EIA) as an industry group. The reason why the external dimensions of the server are stipulated is to facilitate the server to maintain an appropriate distance when installed on the rack, and to correspond one-to-one with the screw holes fixed on the rack to facilitate screw fixation. The “1U/2U rack-mounted UPS battery” is actually a UPS battery product that meets EIA specifications, and the product can be successfully installed on a server rack of corresponding size. The corresponding size and height of 1U is 1.75 inches = 4.445 centimeters, and 2U is twice the size of 1U, which is 8.89 centimeters, and so on. The design of the 1U/2U rack-mounted…
