Enovix Corporation (‘Enovix’) designs, develops, manufactures, and commercializes next generation Lithium-ion, or Li-ion, battery cells that significantly increase the amount of energy density and storage capacity relative to conventional battery cells.
The company’s battery’s mechanical design, or ‘architecture,’ allows it to use high-performance chemistries while enabling safety and charge time advantages.
Between May and July of 2024, the company relocated its first production line (‘Fab1’) research and development (R&D) pilot line equipment to Fab2 in Malaysia. In August 2024, it officially opened its facility in Malaysia (‘Fab2’) production facility, located at the Penang Science Park in Malaysia. The company has three manufacturing lines at Fab2, including the R&D-focused pilot production line, the Agility line, and the High-Volume (‘HVM’) line. In October 2024, it commenced shipping battery cells from the Agility line, and as of the end of 2024, it had completed Site Acceptance Testing (‘SAT’) for the Agility and HVM lines.
Producing the company’s Battery
In addition to designing the company’s battery, it also develops the advanced manufacturing processes needed to produce its batteries in high volume and at low cost.
The company uses the conventional Li-ion battery cell manufacturing techniques for processes, such as electrode coating, cell packaging, testing, and aging. It then uses its own proprietary tools on steps, such as cell assembly, where the company’s laser patterns and stacks the electrodes, and then applies a stainless steel constraint.
Standard Li-ion battery production involves: electrode fabrication, cell assembly, and battery packaging and formation.
Electrode Fabrication — In 2023, the company acquired Routejade to bring this electrode fabrication capability in-house.
Cell Assembly — It has developed a more precise roll-to-stack cell assembly process to enable a silicon anode that increases Li-ion cell energy density and maintains high cycle life.
Enovix Roll-to-Stack Cell Assembly — The company has designed proprietary tools, produced for it by precision automated equipment suppliers, which incorporate patented methods and processes to achieve precise laser patterning and high-speed roll-to-stack cell assembly.
Battery Packaging and Formation — The company’s battery uses the same battery packaging and formation process as a conventional Li-ion battery, with the exception of the pre-lithiation process. In its manufacturing process, the company adds an incremental lithium source during packaging, which is then diffused into the cell during the formation process.
Products
The company’s product strategy is built on close collaboration with customers to understand their specific performance requirements, such as energy density, cycle life, charge rate, and battery size. In 2023, it shifted from a horizontal business strategy, which focused on serving hundreds of customers with standard-sized batteries, to a vertical business strategy targeting a smaller group of large customers that require custom cells. The company directly engages with OEMs to fine-tune its battery technology for maximum performance within the constraints of their devices.
The company develops battery ‘nodes’ that share a common set of active materials and mechanical design, enabling it to produce batteries in various sizes. Its technology roadmap is built around a structured progression of these nodes, with each new generation, such as EX-1M, EX-2M, EX-3M, and so on, delivering substantial improvements in energy density. By leveraging both material and design innovations, the company aims to push the boundaries of Li-ion battery performance. Continuous innovation will allow it to introduce higher-performing battery nodes over time, delivering meaningful performance gains for its customers ahead of market trends.
In 2023, the company acquired Routejade, a leading battery manufacturer in South Korea that supplies batteries for wearables, medical devices, headsets, activity trackers, and industrial equipment. Routejade's patented encapsulation technology provides for design flexibility and structural safety, enabling high-energy-density Li-ion batteries primarily for IoT and wearable applications. The company also produces high-power batteries using Z-Folding technology, serving customers in the medical, industrial, aviation, and defense sectors. Routejade offers three main product categories. The PD series consists of rechargeable coin cells commonly used in healthcare and IoT applications. The FLPB and ASDB series utilize encapsulation technology—FLPB providing structural safety and ASDB maximizing design flexibility for compact devices—both primarily used in wearables and medical applications. The SLPB series features high C-Rate Z-Folding batteries optimized for high-power applications in the medical, industrial, aviation, and defense markets. One of Routejade’s key strengths is its in-house pack assembly, serving over 50 global end-user customers with a wide range of customized solutions to meet diverse market demands.
