Description

Technical Field

[0001] This utility model relates to the field of carbon emission accounting technology, and more specifically, to a carbon emission accounting system for a lithium battery cathode material sintering equipment. Background Technology

[0002] Lithium-ion batteries, as a highly efficient and environmentally friendly energy storage method, are of great significance to promoting energy transition and sustainable development. They are widely used in industries such as new energy vehicles, energy storage, and electronic products, and their application scenarios are constantly expanding, resulting in a sustained high-speed growth in market size. However, with the expansion of the lithium-ion battery industry, the carbon emissions generated by lithium-ion batteries are becoming increasingly prominent.

[0003] The carbon emissions from lithium-ion batteries involve the entire lifecycle, from raw material acquisition and battery production to recycling. The main raw materials for lithium-ion batteries include cathode materials (such as lithium iron phosphate), anode materials (such as graphite), electrolytes, separators, and current collectors. Cathode material manufacturing generates significant amounts of greenhouse gases. Currently, upstream resources for cathode materials include minerals such as lithium, cobalt, nickel, and manganese, while lithium-ion compounds mainly include lithium carbonate and lithium hydroxide. Lithium carbonate releases carbon dioxide during sintering. Currently, research on carbon emission accounting methods for lithium-ion battery production is relatively limited, particularly regarding carbon emission monitoring and accounting technologies during cathode material sintering. Traditional carbon emission estimation relies on post-hoc statistics and estimates, lacking real-time and accurate data acquisition and analysis methods, making it difficult to accurately, automatically, and efficiently calculate carbon emissions during the sintering process of lithium-ion battery cathode materials. Utility Model Content

[0004] The main objective of this invention is to provide a carbon emission accounting system for lithium battery cathode material sintering equipment, in order to solve the problem in the prior art that it is difficult to accurately, automatically and efficiently calculate the carbon emissions during the sintering process of lithium battery cathode materials.

[0005] To achieve the above objectives, this utility model provides a carbon emission accounting system for a lithium battery cathode material sintering equipment, comprising: a sensing module, including a lithium salt mass measurement unit, an analysis unit, a gas flow detection unit, a gas concentration monitoring unit, and a power monitoring unit for acquiring carbon emission accounting data; a transmission module electrically connected to the sensing module; and a data module electrically connected to the transmission module, wherein the transmission module transmits the carbon emission accounting data to the data module, and the data module calculates the total carbon emissions based on the carbon emission accounting data acquired by the sensing module.

[0006] Through the above setup, the real-time data acquisition by the lithium salt quality measurement, analysis, gas flow detection, gas concentration monitoring, and power monitoring units in the sensing module, combined with the instant communication capability of the transmission module, ensures the real-time and accuracy of carbon emission data, avoiding the delays and errors present in traditional post-event statistics. Furthermore, based on the data transmitted by the sensing module, the data module automatically calculates the total carbon emissions during the sintering process, including carbon dioxide, nitrous oxide, and emissions from purchased electricity, significantly improving the efficiency of the calculation, reducing the complexity and time consumption of manual calculations, and ensuring rapid response in data processing. In this way, the carbon emissions during the sintering process of lithium battery cathode materials can be accurately, automatically, and efficiently calculated.

[0007] Preferably, the lithium salt mass measuring unit is a weighing instrument, which is located at the material inlet of the sintering equipment.

[0010] With the above settings, the elemental composition and content of the sintered cathode material can be analyzed in real time.

[0011] Preferably, the gas flow detection unit is a gas flow meter, which is installed at the exhaust gas outlet of the sintering equipment.

[0012] The above settings enable real-time measurement of the exhaust gas flow rate generated during the sintering process, ensuring real-time acquisition of exhaust gas emission data.

[0016] The above settings enable real-time monitoring of the power consumption of the sintering equipment, which helps to quantify the carbon emissions generated by purchased electricity and thus comprehensively assess the carbon emissions of the lithium battery cathode material sintering process.

[0017] Preferably, the transmission module includes communication equipment, such as a switch or router.

[0018] The above settings not only ensure that the various data collected by the sensing module (including lithium salt quality, cathode material elemental analysis, gas flow rate, nitrous oxide concentration, and power consumption) can be transmitted to the data module in real time and stably, but also significantly reduce the risk of data loss and delay through its efficient data processing and forwarding capabilities.

[0019] Preferably, the data module includes a server, which contains carbon emission accounting software and database software.

[0020] With the above settings, the server's built-in carbon emission accounting software can receive and process data from the transmission module. Through preset calculation models, such as material balance and emission monitoring models, it can automatically and quickly calculate the total carbon emissions during the sintering process, including carbon dioxide, nitrous oxide, and the carbon emission contribution of purchased electricity, greatly improving the efficiency and accuracy of carbon emission accounting. Furthermore, the database software in the server is responsible for storing all carbon emission-related data, including real-time monitoring data, historical data, and the calculated carbon emission accounting results. This facilitates long-term data preservation and traceability, and also provides rich data resources for subsequent data analysis, report generation, and decision support.

[0021] Preferably, the carbon emission accounting system of the lithium battery cathode material sintering equipment also includes an application module electrically connected to the data module, used to display the total carbon emissions.

[0022] With the above setup, the application module is electrically connected to the data module, enabling it to receive and display in real time the total carbon emissions calculated by the data module, including carbon dioxide, nitrous oxide, and emissions from purchased electricity. This allows production managers and environmental engineers to monitor the carbon emissions during the sintering process in real time.

[0023] Preferably, the application module includes at least one of a workstation, a network printer, and a web client.

[0024] Through the above settings, the workstation provides an intuitive user interface, enabling operators to view and monitor carbon emission data during the sintering process in real time, including emissions of carbon dioxide, nitrous oxide, and purchased electricity. This ensures the immediate availability of data, facilitating production managers to make decisions and adjustments based on real-time information. The integration of a network printer allows users to easily print carbon emission reports and related data files, facilitating offline archiving, sharing, and review. The introduction of a web-based interface breaks down geographical limitations, enabling remote access and monitoring. Production managers, environmental regulators, or decision-makers can view carbon emission information in real time through any internet-connected device. This not only enhances information transparency but also facilitates cross-regional team collaboration and remote decision support. Especially in modern distributed production environments, the remote access capabilities of the web-based interface greatly improve the system's management efficiency and response speed.

[0025] By applying the technical solution of this utility model, real-time data acquisition from the lithium salt quality measurement unit, analysis unit, gas flow detection unit, gas concentration monitoring unit, and power monitoring unit in the sensing module, combined with the instant communication capability of the transmission module, ensures the real-time and accuracy of carbon emission data, avoiding the delays and errors present in traditional post-event statistics.
