Breakthrough in Heat Dissipation! TANZ ENERGY Awarded Utility Model Patent for "Modular Lithium-Ion Cell Assembly"

Since its establishment, Guangdong TANZ ENERGY Technology Co., Ltd. has been deeply engaged in the research, development, and application of eco-friendly batteries. Relying on its profound expertise in electric two-wheeler batteries, the company had shipped more than 1.07 million lithium-ion battery packs for global electric bicycles by the end of 2021. Its products are widely used in electric bicycles, electric motorcycles, electric scooters, electric water sports equipment, and other scenarios, aligning with the rapid development of the global electric mobility industry and the upgrading demand for lithium-ion batteries for electric bicycles.

While consolidating its core business, TANZ ENERGY proactively responds to market trends. In 2022, the company further refined the lithium-ion battery market for electric bicycles, and advanced the commercialization of outdoor portable energy storage power supplies (such as the TC700W series) and residential energy storage, as well as small and medium-sized commercial & industrial (C&I) energy storage products. By building an international B2B platform and establishing a professional foreign trade team, the company is accelerating its overseas expansion, committed to being "a qualified practitioner of efficient, stable, green, and eco-friendly new energy" and promoting China’s high-quality new energy products to the global market.

From developing single power batteries to expanding diversified energy storage products, TANZ ENERGY is steadily composing a new chapter of overseas development for Chinese new energy enterprises. With continuous deep cultivation and innovative strategic layout, TANZ ENERGY has achieved another major technological breakthrough. Recently, the China National Intellectual Property Administration (CNIPA) officially granted Guangdong TANZ ENERGY Technology Co., Ltd. the utility model patent for A Modular Lithium-Ion Cell Assembly with Excellent Heat Dissipation, with the patent announcement number: CN223230387U. The approval of this patent marks a key technological breakthrough for TANZ ENERGY in lithium battery thermal management, structural design, and integrated cell assembly heat dissipation technology, further strengthening the company’s core technological advantages in lithium battery research and development and manufacturing.

At present, the global electric mobility, residential energy storage and commercial & industrial energy storage industries are developing rapidly, and the market has set higher standards for the safety performance, cycle life and installation adaptability of lithium-ion battery packs. Lithium batteries generate substantial heat during high-rate charge and discharge and long-term continuous operation. Unreasonable heat dissipation structure design easily leads to excessive cell temperature and large local temperature differences, causing accelerated cell degradation, bulging, and deformation, and even potential thermal runaway safety risks in severe cases. Therefore, high-efficiency heat dissipation structure design has become a core challenge restricting the quality upgrade of modular lithium-ion cell assemblies.

Targeting common industry pain points, including low heat dissipation efficiency, complex structural layout, large space occupation, and difficult assembly, the R&D team of TANZ ENERGY has conducted in-depth research and developed an integrated heat dissipation mounting plate structure with integrated stamping-molded support protrusions and water cooling pipe installation slots. Through an innovative mechanical structure layout, the design enables precise positioning and rapid assembly of both air cooling and water cooling heat dissipation systems without additional fasteners, greatly simplifying the overall assembly process of the battery pack.

This patented technology features multiple core advantages. The integrated molding structure with dual heat dissipation compatibility significantly improves the overall heat dissipation uniformity and efficiency of the cell assembly, effectively controls the operating temperature of cells, avoids high-temperature safety risks, and greatly extends the cycle life of lithium batteries. In addition, the integrated structure greatly reduces the overall volume and space occupation of the cell assembly, featuring a compact and standardized structure with strong adaptability. It can flexibly meet the installation and layout requirements of various devices and is perfectly suitable for modular combined applications in multiple scenarios.

As a new energy enterprise specializing in the research and development, production and sales of lithium-ion cells, electric two-wheeler power battery packs, and distributed energy storage systems including residential energy storage and small and medium-sized commercial & industrial (C&I) energy storage, Guangdong TANZ ENERGY always takes technological innovation as its core driving force and attaches great importance to the layout of independent intellectual property rights and core technology research and development. The company continuously focuses on key technological fields such as lithium battery thermal management, structural integration, safety protection, and energy efficiency optimization, increases R&D investment, improves the R&D system, and solves common industry problems through technological innovation.

The successful grant of this heat dissipation patent not only fully validates the R&D and innovation capabilities of TANZ ENERGY but also provides solid technical support for the performance and quality upgrade of the company’s power batteries and energy storage products. In the future, TANZ ENERGY will continue to deepen its presence in the lithium battery new energy sector, tackle key industry technical challenges, enrich its patented technology portfolio, and empower the high-quality development of the global electric mobility and energy storage industries with safer, more efficient, and more compact green energy products and solutions, creating greater value for partners at home and abroad.
