Basic knowledge of the Resource Effective Utilization Promotion Act related to lithium batteries and secondary battery products.

The Resource Effective Utilization Promotion Act is a law established with the aim of promoting the effective use of resources and reducing waste, which may require initiatives related to product design and recycling labeling. In particular, for products using secondary batteries such as lithium-ion batteries and nickel-metal hydride batteries, it is considered important to understand the systems related to battery recycling promotion and labeling. This document organizes the basic concepts of the Resource Effective Utilization Promotion Act and provides an easy-to-understand overview of the systems related to products using lithium batteries and secondary batteries. It introduces basic information that personnel in the design, development, and quality departments of companies should be aware of, including the categories of applicable products, the concepts of battery labeling, and initiatives related to resource circulation. Please note that the scope of application and detailed requirements of the law may vary depending on product specifications and uses. When implementing actual measures, please check the latest legal information and publicly available materials from relevant agencies.

Reliable battery performance that does not lose power even in extreme cold environments.

The lithium polymer battery developed by EEMB, designed to operate at -40°C, aims to provide reliable power performance even in extremely low-temperature environments. Typically, low temperatures lead to increased internal resistance and suppressed chemical reactions, resulting in reduced output. However, this model has demonstrated that it can discharge approximately 80% of its rated capacity even at -40°C, and maintain a charging efficiency of around 80% at -20°C, thanks to optimized manufacturing processes and materials. Additionally, the cell design incorporates a structure that suppresses extreme thermal expansion and contraction, as well as electrolyte freezing, ensuring long-term cycle durability and reliability (mitigating degradation due to temperature fluctuations). It is also capable of customized battery pack designs tailored to implementation constraints. This battery solution serves as the "last line of defense" in applications where power loss is unacceptable in low-temperature environments, such as cold region monitoring systems, polar exploration equipment, and refrigeration and logistics sensors.
