REPT Battery Three Major Paths to Breakthrough and Development

Using leading technology and advanced production capacity to help global transportation and energy transition to green is becoming a new label for the global layout of China's new energy industry chain companies. In early May, Chinese President Xi Jinping paid a state visit to France. During the visit, Xi Jinping pointed out that China's new energy industry has developed real skills in open competition and represents advanced production capacity, which not only enriches global supply and alleviates global inflation pressure, but also makes great contributions to the global response to climate change and green transformation. . "China has world-recognized expertise in many fields, such as batteries, new energy vehicles, and solar photovoltaic panels." French President Macron also bluntly said that he welcomes Chinese companies to invest and cooperate in Europe and hopes to strengthen cooperation with China to jointly safeguard European values. The supply chain is safe and stable. At present, competition in the new energy battery industry in the Chinese market is fierce. How companies can survive and win in the internal market competition has become a common proposition that the battery industry chain must face and think about. The answer given by REPT is: technological innovation, cost control and global market strategy. Moreover, based on these three major paths, REPT has already occupied a place in the global new energy battery market.
 

Expanding production of "cautious" new lithium battery forces

Data shows that REPT lifepo4 battery installed capacity has risen to 6th in the world in 2023; energy storage battery shipments rank 4th in the world. Despite the rapid development of international customers, REPT is more "cautious" in terms of production capacity layout. Cao Hui, chairman of REPT, once pointed out that blind expansion is not an asset but a burden. "REPT's capacity utilization has always been relatively high, which is very important for stabilizing the quality of our products and reducing costs." Xia Baojia, chief technical expert of REPT, said that REPT has always attached great importance to the quality and utilization of production capacity. Based on the strategy of combining power and storage, REPT's capacity utilization is well controlled. Up to now, REPT has built domestic green battery production bases in Wenzhou, Jiashan, Liuzhou, Foshan, Chongqing and other markets covering East China, South China, Southwest China and other markets, and plans to complete the planning and layout of global green battery bases in Southeast Asia, Europe and other countries around 2025. "By 2025, REPT will have an annual green battery production capacity of 150GWh, supporting the company's global delivery." Xia Baojia said.

Green lithium ion battery technology innovation continues to promote product iteration

Looking back, although it has only been established for seven years, REPT has already played an important role in the power and energy storage markets, of which REPT's technological innovation and product strength are the key. Since its inception, REPT has not been willing to be a follower. The company's R&D team with Cao Hui as the core has tackled multiple core links such as battery technology, spatial structure, and material selection, focusing on building REPT's "product strength." Among REPT’s numerous materials, cells, processes, structures and product innovations, the most representative one is undoubtedly the “asking top” technology. The internal structure of prismatic batteries, which currently dominate the market, generally adopts a long lug (approximately 32mm) structure design. This design not only wastes the internal space of the battery cell, but also has a long electronic transmission path, which cannot maximize the battery performance.

In response to this pain point, REPT took the lead in the industry to make innovative breakthroughs in the internal structure of the battery, breaking the traditional space restrictions, proposing the concept of "fragmentation" of the cover, simplifying the cover process, so that the core and cover can be directly connected. At the same time, the bending method of the tabs is optimized (no U-shaped bending) to achieve an integrated design, shortening the length of the tabs from 32mm to 13mm, and reducing the original top space from 15mm to 8mm, making the battery The internal space utilization rate has increased by more than 7%, and REPT vividly named this technology “asking the top”. By shortening the tabs and narrowing the top space, REPT's "top-asking" technology significantly improves the energy density, space utilization and safety of the battery core by optimizing space utilization and tab structure, while reducing costs and achieving Super fast charging performance. Among them, the capacity of the Wending battery cell is increased by 10% under the same size, the volume energy density can reach 480Wh/L (lithium iron phosphate) and 650Wh/L (ternary battery), the length of the tab is shortened by 60%, and the electron transmission path is optimized. The lithium-ion transmission speed is increased by 30%, has 2-4C ultra-fast charging performance, and the structure is more stable and safer. Based on this, REPT has "wented" the entire range of power and energy storage batteries and launched the Wending family of batteries covering the entire range of power and energy storage.

In terms of pure electric vehicles, the REPT 158Ah lifepo4 battery 450 PACK has a full package power of more than 70kWh, which meets the 600-700km range requirement; the 200Ah three-way top battery has a volumetric energy density of 650 Wh/L, and the 650 PACK has a full package power of more than 110kWh, which can achieve 800 -1000km cruising range. In terms of PHEV models, data shows that the 148, 194, and 220 series PHEV batteries supported by Wending technology have a 10-80% SOC charging rate of 2-4C fast charging, an energy density increase of 5-7%, and can reach 180Wh/kg. , to meet the pure electric range requirement of PHEV models of 300km, the pulse power is increased by 8-10%, the cycle life is greater than 4500 cycles, and cold start can be achieved at minus 35°C. In terms of energy storage products, the Wending 345Ah energy storage cell, which integrates multiple core technologies such as structural innovation technology, process technology and equipment technology, and electrochemical solid-liquid interface technology, has a measured capacity of 350Ah+, an increase of 23% compared to 280Ah in the same period last year. The space utilization rate is increased by 4.5%, the energy is upgraded to 1.12kWh, and the volume energy density is increased from 357Wh/L to 440Wh/L. In addition, based on "asking top" technology, REPT asking top battery cells reduce carbon dioxide emissions by about 10% compared with batteries of the same size, truly assisting the green transformation of the automotive and energy storage industries. It’s not just technological innovation at the cell level that helps customers save energy and reduce carbon emissions. At the system level, REPT launched the lithium battery green CTP system design concept. In the battery system structural design, it innovatively applied a glue-free structure, which not only has high reliability, but also facilitates the maintenance of the battery system and battery recycling, which greatly improves the battery Recycling capabilities.

Global thinking and market layout

Companies that master advanced technology, green batteries, global production capacity and secure supply chains have gradually become the core factors that major European and even global car companies and energy storage system integrators consider when choosing battery suppliers to promote green transformation. Last month, REPT reached cooperation again with Powin, a world-renowned energy storage integrator, and signed a cooperation framework agreement for 12GWh of 320Ah energy storage cells to actively provide green energy to the world. With leading technology and green batteries, REPT power and energy storage batteries have won cooperation with international car companies such as Stellantis, Nissan, smart, and volvo, as well as international energy storage customers such as Powin, Energy Vault, and Vena Energy, to help global customers achieve green transformation and provide Green kinetic energy products. Power and energy storage customers are all over the world. In order to meet localized industrial supporting facilities, REPT's overseas expansion has long been included in the company's agenda. Relying on Tsingshan Industrial's deep international corporate foundation, its global large-scale manufacturing experience and operating experience, and its extensive deployment of resources, REPT's competitive advantages in the new energy track are highlighted. It is reported that in order to help the global energy and transportation industry transform into green, Tsingshan Group vigorously develops new energy industry chain layout at home and abroad, and controls the use of sustainable and green energy, zero carbon emissions and material cost and price risks.

Tsingshan Group makes full use of the rich mineral resources, hydropower resources in Indonesia, Africa, South America and other countries, combined with green power resources such as solar power and wind power, to create low-carbon clean energy, and attracts domestic and foreign battery cells through zero-carbon industrial parks in many places around the world. Upstream material companies and international car manufacturers have implemented production capacity to build a green energy industry cluster. In the global layout, Southeast Asia and Europe are the regions where REPT is currently advancing relatively quickly. In September last year, REPT's European subsidiary was officially launched in Munich, Germany, becoming an important pivot of the company's strategic layout in Europe.

In the future, REPT will rely on leading green batteries, through strict quality management and localized team building, intelligent green factories can achieve high-quality production capacity replication in many countries and regions, with a global strategic vision, in the industry "Breakthrough" in a new round of competition.
