How Rivian’s New R2 Battery Will Boost Range and Cut Costs

Share the News

Rivian is laying the groundwork for the launch of its highly anticipated R2 platform, expected in 2026. Central to this vehicle’s performance and cost-efficiency is a new battery partnership with LG Energy Solutions (LGES), which will supply advanced cylindrical cells manufactured in the United States. This collaboration is designed to ensure Rivian’s R2 models have exceptional range, durability, and performance while also supporting domestic battery production and aligning with the latest industry standards.

High-Efficiency Batteries Made in the U.S.

The partnership between Rivian and LGES is set to supply 4695 cylindrical battery cells, known for their larger size and higher energy density compared to previous models. LGES will manufacture these cells at their Queen Creek, Arizona, facility, aligning with Rivian’s commitment to U.S.-based production. This approach is not only beneficial from a logistics and supply chain perspective, but it also ensures compliance with federal incentives under the Inflation Reduction Act, which promotes domestic EV component manufacturing.

Advantages of the 4695 Cylindrical Cell

The 4695 cell’s large form factor provides Rivian with several key advantages for the R2:

  • Increased Energy Density: The 4695 cells offer greater energy storage capacity, allowing Rivian to boost range without increasing the weight or size of the battery pack significantly.
  • Simplified Design: The larger cell format reduces the number of individual cells needed in each battery pack, simplifying production and reducing overall manufacturing costs.
  • Manufacturing Efficiency: The new cells allow Rivian to streamline battery pack assembly, which the company anticipates will improve efficiency by approximately 45%. This improvement aligns with Rivian’s goal to scale production while maintaining cost-effectiveness.

A Next-Gen Battery Pack Design for the R2

Rivian’s R2 battery pack incorporates innovations that make it lighter, more durable, and less complex. The R2 platform will introduce a simplified pack structure that reduces weight while improving energy efficiency. By integrating fewer parts and focusing on structural efficiency, Rivian aims to deliver a cost-effective yet high-performance battery solution.

The R2 battery pack will include a structural battery pack design, where the battery cells form an integral part of the vehicle’s floor. This design reduces the need for additional structural components, thus lowering material costs and assembly time. Additionally, the R2’s battery pack is engineered for enhanced thermal management, ensuring long-lasting performance in diverse environments—ideal for Rivian’s adventure-focused owner.

Cost Savings and Efficiency Gains

Rivian’s investment in the 4695 cell format and battery pack design is part of a broader strategy to improve the R2’s affordability. Rivian expects the R2 battery pack to cost 45% less per kilowatt-hour (kWh) than the second-generation R1 packs, a significant cost reduction that will enable Rivian to price the R2 more competitively while maintaining robust profit margins.

Aligning with Rivian’s Long-Term Vision

This partnership with LGES and the development of the 4695 battery cell exemplify Rivian’s long-term commitment to innovative, cost-effective, and U.S.-based production. With LGES supplying the battery cells and Rivian implementing its proprietary battery pack structure, the R2 is poised to deliver a blend of high performance and affordability. This approach not only enhances Rivian’s brand position in the competitive EV market but also brings the company closer to achieving sustainable growth and profitability.

The Road Ahead

The R2 platform is designed to reach a broader global market segment than the R1, offering Rivian’s adventure-focused technology at a more accessible price point. Rivian’s focus on battery innovation through strategic partnerships will be key to the R2’s success, supporting long-range, durability, and efficiency. By leveraging LGES’s advanced battery technology and its simplified battery architecture, Rivian is ensuring the R2 will deliver on both performance and cost-efficiency, making it a game-changer in the EV landscape.
