Product Quality and Safety

LG Energy Solution is committed to delivering products and solutions that exceed customers’ expectations. To that end, we have put in place a rigorous quality management system and programs to ensure product quality and safety throughout all manufacturing processes and continuous improvement in collaboration with all members and partners.

Quality Management System

With a view to ensuring high quality and reliability standards for all products and processes, LG Energy Solution has put in place a quality management system across all facilities certified with IATF 16949:2016 Automotive Quality Management System and ISO 9001:2015 Quality Management System standards. We intend to maintain the effective operations of such a quality management system through a continued process of 1) developing and implementing quality management programs, 2) evaluating, at least annually, the progress against targets, and 3) enhancing internal standards and processes based on the findings from the regular evaluation and stakeholder feedback.

Status of Certifications Acquired

At LG Energy Solution, the headquarters, manufacturing plants in operation and R&D centers are certified with IATF 16949:2016 Automotive Quality Management System and ISO 9001:2015 Quality Management System standards. As part of certification process, we conduct third-party audits of quality management system, including surveillance or maintenance audits and re-certification audits. Further, we conduct internal audits, annually, to ensure facility-level compliance with company-wide regulations and standards and continuous improvement, thereby exceeding stakeholder expectations.

LG Energy Solution has obtained the international certificate of quality system for 100% of its wholly-owned manufacturing plants in operation (as of April 2024).

Quality Risk Management

Quality issues can arise at any stage of business, including product development, components or parts sourcing, inventory storage, and product delivery. Therefore, it is crucial to establish a company-wide system and process that enables to promptly identify, respond to and efficiently mitigate any quality risk.

LG Energy Solution operates a company-wide risk management system to proactively identify, prevent, mitigate and effectively respond to potential and/or actual risks in various aspects of business. Product safety and quality is one of key risk areas LG Energy Solution defines as part of this comprehensive risk management system. While we apply different processes and protocols depending on the nature of risk area, product safety and quality risk is addressed by different processes and protocols, including crisis management, business continuity management, and risk management, depending on the root cause of the situation.

In particular, our Business Continuity Management System (BCMS) is established based on and certified with ISO 22301 to validate and enhance the continuity, consistency, and effectiveness of our risk management system. Further, all of our operating sites undergo internal evaluation based on our own risk management criteria, which align with ISO 22301 standards.

Securing a stable supply of parts and materials is another key element of product safety and quality management. To mitigate risk associated with disruption in parts and materials sourcing, emergency cases are clustered into few categories, including natural disaster, workplace accident, suppliers’ management issue such as bankruptcy, layoff or strikes, and geopolitical issue and related price fluctuation. For each category of emergency case, a formalized process and manual is put in place that encompasses case identification, reporting protocol, operation of emergency taskforce, and mitigation and remediation planning. Mitigation measures are planned in a phased manner – in the short-term, mitigation measures include temporary sourcing of alternative, production plan adjustment; in the mid- to long-term, mitigation measures vary ranging from dual sourcing, alternative/new supplier identification, to the change of manufacturing site. The category-specific processes and manuals are reviewed and updated on a regular basis to ensure effectiveness of product safety and quality management process and to minimize any adverse impacts and prevent recurrence of such event.

Quality Management Process

LG Energy Solution’s quality management is integrated in different stages of product lifecycle and based on a quality control and assurance process against internally developed standards that go above and beyond international standards. Such process covers all our production facilities in operation.

Quality Management Process


At the product development stage, LG Energy Solution follows a rigorous ‘Product Quality Planning Process’ to ensure the design of products meets customers' quality requirements and international standards. With in-house capacity to test product performance, safety, reliability from the design to materials & parts approval phases, we identify and mitigate potential or emerging quality and safety concerns in a preemptive manner. Each of newly developed products, before mass production, should undergo relevant international certification process.


At LG Energy Solution, we maintain strict quality control measures throughout the production process, conducting thorough inspections of all parts and products at each step. We have put in place various risk mitigation process such as dual sourcing, to mitigate potential risks caused by unexpected changes in the project volume and/or in supply chains.

Capacity Building in Quality Management

Through LG Energy Solution Battery Academy (LBA), we offer a comprehensive training and capacity development program designed to enhance employee skills and capabilities in assuming respective role. The program is offered to all employees regardless of their position or employment contract type.
In particular, the quality managers across all our facilities worldwide are regularly provided with specialized training in various areas, including quality management, product safety, reliability & statistics, and relevant global regulations. The training courses are complemented with on-site hands-on training and education to further enhance their understanding and capability in quality management.
Further, to promote awareness and foster a culture of quality assurance in each member’s daily work, all employees are offered with Compliance Training Programs, including a ‘Quality Assurance for Customer Satisfaction and Quality Mindset’ course which is mandatory for all employees and is conducted twice a year.

Supplier Quality Management

LG Energy Solution’s quality management integrates a systematic supplier quality management, which aims to ensure consistency and stability in quality and continuous improvement of suppliers’ capability in quality assurance and control. Through a ‘Supplier Quality Management System,’ we monitor real-time data on various indicators of suppliers quality and carry out product reliability risk management.

Supplier Quality Assurance System

LG Energy Solution operates a comprehensive ‘Supplier Quality Assurance System’ that regularly assesses the quality management level of all our suppliers. Key assessment criteria includes customer requirements and global standards, and the scope of assessment is suppliers' quality management systems and processes. The assessment framework is regularly reviewed and updated to ensure that our products meet the expectations from our global customers. In addition to the regular assessments, we conduct ad-hoc evaluations of our suppliers' quality assurance capacity and quality improvement programs. This approach enables us to continuously strengthen our 'Supplier Quality Assurance System’ and ensure that our products consistently meet the highest standards of quality and reliability.

Supplier Quality Certification Process and Capacity Building Program

In order to achieve the highest level of product quality and safety, it is crucial to assess and manage suppliers' product quality and enhance their quality management capacity. LG Energy Solution runs a supplier quality assessment program on a quarterly basis, the results of which are tied with certification, incentive/penalty programs and capacity building initiatives. The assessment program is designed to evaluate each supplier’s quality management system, quality performance and preventive quality control, and rank them in five levels – S, A, B, C and D – based on the score (Q-Score). LG Energy Solution issues certificates and the record of certification is archived and tracked through our Supplier Quality Management System (QMS).

Those suppliers designated with two lowest ranks are required to participate in the "Supplier Quality Rank & Rank Up Program," designed to address their weaknesses and areas for improvement. LG Energy Solution also utilizes this ranking system for the "Supplier New Biz. Hold (SNBH)" program. Under this program, suppliers who receive the lowest D for two consecutive years are excluded from our vendor pool and restricted from entering into new business contracts with LG Energy Solution. This measure ensures that we maintain a high standard of quality and performance from our suppliers, and encourages suppliers’ continuous improvement and adherence to our quality management requirements.
