0.01℃ Closed-Loop Compensation: Injection Pump Breaks Through Cell Consistency Bottleneck

Guangzhou Ascend's temperature-compensated constant flow injection pump has been granted a national patent and is now in mass production and shipment. 

As power battery production capacity races toward the terawatt-hour (TWh) level and the industry trend of scaling up single-line production by 1–2 times, efficiency, precision, and stability have become the core evaluation indicators for electrolyte injection equipment.

The electrolyte injection volume directly determines the performance and service life of lithium batteries. Density changes in the electrolyte caused by temperature fluctuations tend to result in accumulated injection errors, which have become a key bottleneck restricting cell consistency and production line yield. 

With extensive expertise in lithium battery electrolyte injection equipment, Guangzhou Ascend Precision has developed the targeted FSH‑CF‑T series constant flow injection pumps, successfully solving the problem of injection volume drift caused by temperature variations. Backed by national patented technology and mature mass production capabilities, Guangzhou Ascend has become a core equipment supplier for top battery manufacturers in their capacity expansion, and has now achieved large‑scale batch shipments. 

Powered by patented technology, a solid foundation is laid for stable mass production.

This mass-produced constant flow injection pump is equipped with a temperature detection module that has obtained national patent certification, and its core design is precisely matched to the demands of large-scale production. 

Fast Response, Precise Compensation: The temperature detection module features a resolution of 0.01℃and enables closed-loop compensation for injection volume fluctuations caused by temperature variations, ensuring consistency in mass production.

Integrated Structure Innovation: The temperature detection module is integrated with the pump body. This compact design supports dense production line layouts and eliminates pipeline loss and temperature lag associated with external devices, which makes it perfectly suitable for 24-hour uninterrupted mass production.

Validated by mass shipments, its mature technology has been recognized by leading enterprises. 

As a pioneer filling the domestic gap in mass production of high-precision temperature-compensated injection equipment, this temperature-compensated constant flow injection pump has passed production line verification at multiple leading battery enterprises. Its shipment volume continues to rise, and it is widely used in the middle and rear-stage injection processes of GWh-level production lines for power batteries and energy storage batteries. 

With the dual core advantages of national patented technology + large‑scale mass delivery, Guangzhou Ascend Precision has further consolidated its industry position, providing efficient and stable equipment support for lithium battery enterprises in capacity expansion. 

Looking ahead, Guangzhou Ascend will focus on the core demands of the lithium battery industry: efficiency improvement, technological iteration and cost optimization. Building on its extensive patent portfolio, the company will continue to develop higher-precision, smarter injection solutions. With reliable mass delivery capabilities, it will work alongside global battery manufacturers to overcome the challenges of large-scale production, injecting strong momentum into the high-quality development of the new energy industry.
