However, it would bring some environmental impact for various aspects:   1. Warm-House Gas Emission When Mining While sustainable batteries are highly significant in combating global warming, mining components used in battery production processes come with environmental concerns. Mining and mineral processing needed in the lithium battery production process contributes to 40% of the climate impact in the overall process[1]. And when digging the metal elements, machines would generate the warm house gases, which exaggerate the global warming. 2. Toxic Materials Utilization Data Center Knowledge[2] shows that some types of lithium-ion batteries integrate toxic materials that can contaminate the water supplies or ecosystem around the mine. In the battery manufacturing process, certain toxic materials, such as nickel, cobalt, and manganese, are often utilized due to their superior electrochemical properties. These materials enhance battery performance and provide reliable efficiency. But the use of these toxic substances carries significant environmental drawbacks. For example, lead and cadmium are highly toxic to humans and wildlife, posing serious health risks if they contaminate soil and water. The disposal of batteries containing these

FAQ about OCV Testing During Battery Inspection

Battery quality testing is key in assessing the cell’s operational performance and quality. OCV (Open Circuit Voltage) testing measures the battery voltage when it’s not connected to any load, and no current is flowing outside the cell. This non-intrusive test provides valuable insights into the battery’s state of charge and health. During battery inspection, people would be perplexed by some concepts and would face some issues. To complete handle that smoothly, you need to know the answers to these common questions about OCV testing.

An open circuit refers to discontinuity in an electrical circuit because no current flows through it. It reflects the true potential difference between the terminals without being influenced by external factors. Q2: What is OCV Testing for Lithium-Ion Battery? For lithium-ion batteries, OCV testing involves determining the cell’s voltage in the resting stage when disconnected from the charge. This apparently simple test depicts the battery’s health, functionality, state of charge, and potential anomalies. These batteries exhibit self-discharge capabilities, which causes the OCV values to drop with time. When the lithium-ion battery has an internal fault, the self-discharge process increases. It causes open circuit voltage to decline beyond the defined limit. A cell with an OCV that is too low or too high indicates a cell quality concern. OCV testing also serves as an initial litmus test to detect defects, imbalances, or inconsistencies early on. It helps manufacturers rectify these issues and ensure that only batteries meeting the highest quality standards proceed. Q3: What are the Differences Between Nominal Battery Voltage and OCV? Here are some basic differences between nominal and OCV voltage types: Nominal Battery Voltage Nominal battery voltage is the standardized or average voltage of a battery under normal operating conditions. For example, the nominal

How Automated Assembly Line Fix the Manufacturing Flaws of Photovoltaic Solution

As the world progressively pivots towards sustainable energy sources, photovoltaic (PV) solutions have emerged as a cornerstone in the renewable energy sector. The significance of PV technology lies in its ability to harness the sun’s abundant energy and convert it into a clean, reliable, and renewable source of electricity. According to the IEA’s annual market report for 2023, global renewable energy capacity saw a growth of 50% compared to the previous year, with solar energy being a significant contributor to this growth[1]. With the global demand for solar energy systems escalating, the industry faces the dual challenge of increasing production volumes while maintaining high capacity and standards of quality. The flaws in manufacturing photovoltaic solutions often pose significant obstacles, hindering the efficiency and reliability of solar energy systems. From defects of cutting and slicing in panel coatings to sealing on solar batteries, these flaws can compromise the yields to meet the order and the performance of the photovoltaic solution. How to fix the intricacies of the photovoltaic manufacturing process? In today’s blog, we are going to examine the common flaws that can arise when manufacturing components in photovoltaic solutions and see how an automated assembly line can solve these challenges in photovoltaic solutions.

Popular Science Post | Exploring Prismatic Cells

The rapid development of new energy technology has made prismatic cells the powerhouse of the new energy era, owing to their outstanding performance and wide range of applications. So, what exactly are prismatic cells, and what unique advantages and uses do they offer?   1.Overview of Prismatic Cells Prismatic cells, as the name suggests, are lithium cells with prismatic alloy casing. Domestic power battery manufacturers mainly use prismatic cells with higher energy density because the structure of square cells is simpler compared to cylindrical ones. Unlike cylindrical cells that use high-strength stainless steel for casings and safety valves to prevent explosions, the overall weight of attachments in square cells is lighter. Prismatic cells have higher structural strength, better tolerance to mechanical loads, lower internal resistance, longer lifespan, minimal decrease in energy density after assembly, and higher space utilization.  2.Advantages of Prismatic Cells High Energy Density: Prismatic cells have a much higher energy density than traditional cells, meaning they can store more energy in smaller volumes and weights. This characteristic makes them widely applicable in fields like aerospace, mobile communications, etc. Long Lifespan: Prismatic cells have a long cycle life, enduring multiple charge-discharge cycles without affecting their performance. This makes them widely applicable and promising in areas such as electric vehicles, energy storage systems, etc. High Safety: Prismatic cells use prismaticalloy casings, which have higher resistance to impact and compression. Additionally, their internal structure is designed rationally to effectively prevent safety hazards like short circuits, overcharging, and over-discharging. [Theoretically, there isn’t a strong correlation between prismaticshell materials and cell safety. 3.Surface Treatment Processes for Prismatic Cells Currently, prismatic alloy casings are the most widely used materials for power cells housings. Existing prismatic shells are typically formed by stamping prismatic sheets to create shells, which are then cleaned for subsequent processes. However, surface scratches caused during stamping or handling can
