The growing demand for energy storage solutions is expected to drive the cell-to-pack battery market going forward. Energy storage solutions are technologies that capture and store energy for later use, enhancing grid stability and supporting renewable energy integration. This demand is fueled by increasing adoption of renewable energy, grid modernization efforts, and the need for reliable power during peak demand periods. Cell-to-pack battery technology improves energy storage by increasing energy density, efficiency, and space utilization while reducing costs, production complexity, and environmental impact. For instance, in January 2024, according to data from the Energy Information Administration, a US-based federal agency, total U.S. utility-scale battery capacity reached approximately 16 GW in 2023 and is projected to grow by 89%, exceeding 30 GW by the end of 2024, with plans to add 15 GW within the year. Therefore, rising demand for energy storage solutions is driving the cell-to-pack battery market.

Major companies in the cell-to-pack battery market are focusing on developing advanced battery systems to enhance energy density, efficiency, and reliability, particularly for electric vehicles like electric buses. Advanced battery systems are designed for higher energy density, improved safety, faster charging, and longer lifespan, boosting overall EV performance. For instance, in October 2025, Ioncor Oy, a Finland-based technology company specializing in EV battery solutions, unveiled a new cell-to-pack (CTP) battery system for electric buses. The CTP system eliminates traditional modules, directly integrating battery cells into the pack, which improves space utilization, reduces weight, and enhances thermal management. This innovation extends driving range, reduces charging time, and lowers total cost of ownership, supporting broader adoption of electric buses in public transportation networks.

In July 2024, Renault’s EV unit Ampere, a US-based semiconductor company, formed a partnership with LG Energy Solution (LGES) to advance next-generation battery solutions for electric vehicles. The collaboration aims to improve access to and deployment of high-performance, sustainable EV batteries, enhancing vehicle efficiency and driving innovation and growth in the electric mobility market. LG Energy Solution (LGES) is a South Korea-based company specializing in the development and commercialization of advanced lithium-ion batteries for automotive and energy storage applications.
