In April of this year, Enpower's first 2GWh solid-state battery advanced intelligent manufacturing base in Anhui Province was launched in Fengyang, Chuzhou, marking a solid step towards the industrialization of solid-state batteries. Less than three months later, this intelligent manufacturing base, built to Industry 4.0 standards, has achieved another milestone—As of early July, the Enpower Battery Technology（Anhui） Co., Ltd. had completed its production ramp-up target and reached its designed capacity.
From the first batch of raw materials to the qualified products coming off the production line, it took only 14 days. From the start of production to achieving the production capacity target, it took less than three months. The Enpower Battery Technology（Anhui） Co., Ltd. has demonstrated its intelligent manufacturing capabilities for the large-scale mass production of semi-solid-state battery cells with its impressive ramp-up efficiency. It has also delivered a referable "Enpower answer sheet" for accelerating the industrialization of the industry.
Rapid iteration across multiple models enables "Enpower Acceleration" .
Since its commissioning, the Enpower Battery Technology（Anhui） Co., Ltd. has successfully introduced and implemented multiple new battery cell products from April to June, with continuous breakthroughs in new product ramp-up and production line changeover efficiency: the commissioning process for the first new product has been progressing efficiently.Quickly achieve over 60% of the designed production capacity When the entire production line undergoes a large-scale replacement and iteration of new products, Only 8 days Qualified battery cells can be produced in a short time, and production capacity and output can be upgraded simultaneously.The new specification battery cells were put into production and quickly reached full capacity. Daily output remained stable at a high level, fully demonstrating the production line's flexible production and rapid ramp-up capabilities.
The ability to roll off the production line with qualified products in 14 days, reach designed production capacity in less than 3 months, and rapidly implement three product upgrades all constitute the core essence of "Enpower Speed"—not only the efficiency of ramping up production capacity, but also the flexible manufacturing capability to quickly respond to diverse customer needs. Behind this achievement lies Enpower's more than ten years of accumulated solid-state battery technology, and is also the inevitable result of the Enpower Battery Technology（Anhui） Co., Ltd.'s deep integration of Industry 4.0 concepts and the full-chain intelligent system layout from the very beginning of its planning.
By leveraging both process and intelligent manufacturing, a closed-loop quality management system is built throughout the entire process.
The Enpower Battery Technology（Anhui） Co., Ltd. focuses on producing the "Powerstone" series of battery cells and has built an industry-leading process and intelligent manufacturing system that runs through the entire production chain, providing a dual guarantee for rapid capacity ramp-up and stable product quality.
On the process side, a 2000L fully sealed automatic mixing machine is used for feeding. Ensure slurry consistency Dual online detection using beta rays and AI vision will The coating surface density accuracy is controlled within ±1.2%. It has reached the advanced level in the industry; it has innovatively introduced thermal composite technology, which the formation time has been reduced to 1.5 hours. This also makes the electrode interface more tightly bonded; coupled with an intelligent capacity distribution system with an energy recovery efficiency of up to 80%, overall production energy consumption decreased by 40%. In addition, the electrode assembly area in the workshop has reached class 10,000 cleanroom standard. We implement low dew point environmental control throughout the entire process, laying a solid foundation for battery cell quality from the environmental perspective.
On the intelligent side, AI visual inspection covers the entire process, and the real-time welding correction system further boosts the yield rate of battery cells to 99.8%. Coordinated scheduling between WCS and WMS systems enables material turnover efficiency increased by 3 times.。
Validating large-scale manufacturing capabilities and jointly opening up new prospects for semi-solid-state commercial applications
Achieving the production capacity target in less than three months is a testament to Enpower's mature and comprehensive intelligent manufacturing system and reliable large-scale delivery capabilities. It also marks a key leap for Enpower from "technological leadership" to "verification of large-scale delivery capabilities," further solidifying our first-mover advantage in the solid-state battery field and providing solid capacity and quality assurance for downstream customer needs.
In the future, Enpower will continue to deepen its expertise in solid-state battery technology and intelligent manufacturing capabilities. On the one hand, it will refine the stability of production processes and product consistency to ensure the high-quality output of every battery cell. On the other hand, it will accelerate product iteration and scenario expansion, work with industry chain partners to promote the deep implementation of products in high-value segmented scenarios, and accumulate manufacturing experience and solidify the industrial foundation for the subsequent industrialization of all-solid-state battery technology, continuously contributing "Enpower solutions".
