Most enterprises in the new energy sector operate within only one segment of the industry chain: some specialize in materials, some manufacture cells, while others assemble systems using purchased components. Tianjin Plannano has taken a different path — it retains in-house control over five core links: materials, electrodes, cells, modules and systems.
This approach comes with substantial costs, yet it delivers tangible benefits.
Starting at the source: Plannano independently develops nano-materials, which puts the starting point of all subsequent processes under its control. The composition, particle size and batch stability of materials do not depend on upstream suppliers. When issues arise, they can be traced directly to the root cause, avoiding the common problem of suppliers shifting blame to one another.
Moving to the electrode stage, the company owns its proprietary dry-process electrode technology. Electrodes form the backbone of cell performance. Thickness consistency and uniform areal density directly determine finished product quality. By keeping the process in-house, every batch of powder processed into electrodes stays within the company’s workflow without outsourcing. All process parameters remain fully controllable.
Further up the chain lie cells and modules. Cell consistency is fundamental to the service life and safety of modules, and modules in turn govern system-level performance. Cells, modules and systems are all manufactured on Plannano’s own production lines. Issues such as mismatched parameters and batch variations are identified before products leave the factory, rather than emerging after installation at the customer’s site.
Value becomes most evident at the system level. Nano-materials, dry-process electrodes, supercapacitors, lithium titanate batteries and energy storage products are not isolated product lines. Instead, they represent the implementation of the same core capabilities across different stages. When a customer requires an energy storage system, Plannano can engage from the material selection phase. What it delivers is not a patchwork of outsourced parts, but an integrated solution developed across the entire chain.
This full-chain operation is backed by a 40,000-square-meter manufacturing plant and a workforce of over 600 employees, including more than 60 PhD and master’s degree holders and over 300 staff with bachelor’s or associate degrees. Its products are exported to more than 50 countries and regions across six continents: Asia, Europe, Africa, North America, South America and Oceania. The ability to sustain stable long-term supply across diverse markets serves as a testament to its full-industry-chain strengths.
For buyers, partnering with a supplier capable of end-to-end production eliminates communication costs, liability disputes and delivery uncertainties associated with coordinating multiple vendors. When capabilities covering materials, electrodes, modules and systems are kept in-house, customers face fewer headaches.
