[0044] Technical terms involved in the embodiments of this application:

[0045] ESG stands for Environmental, Social, and Governance. These three dimensions form a framework for assessing corporate sustainability and social responsibility. ESG standards are used to measure a company's environmental, social, and governance performance and help investors, financial institutions, and other stakeholders understand a company's sustainability and long-term risks.

[0046] Currently, batteries (in this application, industrial batteries and electric vehicle batteries with a capacity of 2kWh or more, hereinafter referred to as batteries) are an important component in the fields of new energy vehicles, energy storage equipment, etc., and information on their performance, safety, recyclability, etc. is of great significance to consumers, regulators, manufacturers, and other parties. However, since the battery industry chain involves multiple links and participants, the collection, exchange, organization, and reporting of battery information are faced with many difficulties and challenges, such as:

[0047] (1) Data silos: Different battery manufacturers, suppliers, recyclers, etc. each maintain their own data systems, lacking unified standards and interfaces, making data sharing and verification difficult;

[0048] (2) Data opacity: Information on the raw material sources, chemical composition, carbon footprint, and recycling of batteries is often not public or incomplete, which leads to information asymmetry for consumers and regulators;

[0050] To address these issues, several international efforts have emerged, such as the Battery Passport concept proposed by the Global Battery Alliance (GBA). A Battery Passport is a digital representation of a battery that conveys information on all applicable ESG and lifecycle requirements, based on a comprehensive definition of a sustainable battery. Each Battery Passport will be a digital twin of its physical battery, supported by the Digital Battery Passport Platform, which provides a global solution for securely sharing information and data.
