Chang Chun, director of research and development of yinpai, deeply interprets the core advantages of “solid cause Tiancheng” technology system and “generous without corner” series of batteries from six dimensions of industry pain points, design concept, core technology, intelligent manufacturing system, product performance and limit testing, and directly hits the core pain points of four mutual constraints of safety, cost, performance and life in the energy storage industry, with the ultimate design concept of “generous without corners”, we break the limitation of single-dimensional upgrade and achieve the best breakthrough in all dimensions. “Dafang without corners” comes from “Tao Te Ching” and means “without corners”, that is, to eliminate all edges, corners, defects and risk dead corners, so that large-capacity square shell energy storage batteries can achieve the ultimate perfection at the physical and electrochemical levels. Through the four corner-free designs of “shape, field, force and safety”, the four major pain points in the industry can be accurately solved.
Core technology: “Gan Gang Kun Network” builds intrinsic safety and realizes semi-solid technology breakthrough
The original “Gan Gang Kun Network” technology system created by Gan Kun version (semi-solid) batteries is the core to realize the leap-forward evolution from liquid to solid, make it the current closest to the solid-liquid hybrid energy storage battery.
“dry class” adopts nano-oxide solid electrolyte coating technology to build a uniform solid barrier on the electrode surface and form a strong protective skeleton, which can not only block the growth of lithium dendrite, reduce the risk of lithium dendrite penetration by 95%, but also inhibit the migration of transition metal, greatly reduce the rate of side reactions, improve high temperature stability, and at the same time build a high-efficiency ion conduction network.
“kunluo” forms a three-dimensional gel electrolyte network through in-situ polymerization of gelled solid electrolyte technology, realizing super-infiltration and bonding of electrode interface, the interface impedance is reduced by 90%, and at the same time, the electrolyte is converted into a flame-retardant state, the flash point is increased by more than 100 ℃, the combustion elements are removed from the source, and the intrinsic safety line of defense is built. dry outline and kunluo are coordinated, so that the battery core can reach the safety level of all-solid battery core.
intelligent manufacturing system: “Tiancheng” four pillars to ensure mass production, the lamination process casts the ultimate quality
6.5GWh exclusive production line, adopts the four pillar technologies of “Tiancheng” intelligent manufacturing, integrates AI algorithm and digital twin technology, and realizes the whole process coverage of ultra-wide coating, ultra-high precision lamination and AI intelligent quality control.The production line adopts industry-leading ultra-wide coating roller pressure, one-out-six process and 3+3 single-mode ring laser, which greatly improves the production efficiency and the area of a single production line is far lower than the industry average.
high-pressure isobaric liquid injection equipment and fully automatic closed-loop coating system ensure process accuracy, and the full-size AI vision 2D + 3D detection system realizes zero defect outflow. Ultra-wide coating (efficiency increased by 200, core consistency improved by 50%) and other processes to improve the cycle life of the core by 15%, capacity efficiency than the traditional production line increased by 200, to ensure the consistency of the core and mass production stability.
product features: “shape field force safety” has no corner design, breaking through the performance boundary
relying on the core technology and intelligent manufacturing system, the “generous no corner” series of batteries realize four corner-free designs, and solve the industry pain points in all directions. The non-corner of the shape adopts high-precision lamination process to replace the traditional winding process to eliminate the problems of pole piece material falling, dead zone and wrinkle. The alignment accuracy of the lamination is improved by 100 compared with the industry benchmark, and the stress uniformity of the pole piece is improved by 40%. The non-corner of the field adopts double ear + three-dimensional honeycomb conductive network design, which reduces internal resistance by more than 30% and improves current distribution uniformity by 25%; the peak value of expansion force is reduced by more than 60% through the coordination of low-expansion negative electrode material and laminated structure and the coordination of Gangang Kun network system. An Zhiwuyu optimized the exhaust channel design, increased the exhaust efficiency by 40%, and the Gankun version removed the fuel, one of the three elements of combustion, realized the essential non-combustion, and completely upgraded the safety protection from “out-of-control diversion” to “original source prevention and control”.
limit verification: far exceeds the national standard test, demonstrating extreme safety
both batteries have passed the national standard limit test, and the vast version of liquid batteries have successfully completed the rare full stab test in the industry; the Gankun version semi-solid battery core did not smoke, catch fire or run out of heat in 10 times the national standard extrusion, full cutting, 200 ℃ hot box (exceeding the national standard 70 ℃ to reach the all-solid level) and 1000-degree fire test. After some tests, the voltage remained normal, verifying the extreme advantage of intrinsic safety.
At the core technology level, the “Gangang Kunluo” technology builds the intrinsic safety of the cell from the source, and the oxide solid electrolyte and the in-situ polymer gel electrolyte work together to greatly reduce the risk of thermal runaway and achieve essentially non-flammable.
the two batteries are accurately adapted to different energy storage scenarios: the vast edition focuses on large-scale energy storage and has the advantages of long cycle life and stable operation over a wide temperature range, adapted to new energy bases, power grid peak shaving and other scenarios, it can help customers reduce operation and maintenance costs by more than 30%. The Gankun version is extremely safe and is specially designed for “zero tolerance” security scenarios such as city centers, data centers and chemical parks. It realizes the safety performance of all-solid-state batteries at a cost close to that of liquid batteries. It is the industry’s first mass-produced semi-solid energy storage large battery.
