On April 20, the 2023 Starting Point Energy Storage Battery Technology Forum, jointly hosted by Starting Point Lithium, Starting Point Energy Storage and Starting Point Sodium organization, was successfully held in Shenzhen. The meeting brought together 500+ guests from energy storage batteries, materials, equipment, components, energy storage integration and applications.  To help double carbon win energy storage" is the theme of this forum. Topband battery Co.,Ltd was invited to attend this forum and delivered a speech on the theme of "Application of Large Cylindrical Batteries in Portable Power Storage" at the conference.

At the forum, Topband battery Co.,Ltd shared some ideas of development of energy storage battery technology, pointing out the current state of development of the industry and the existence of pain points, which attracted the high attention of guests and media. Together with industry guests, we made an in-depth discussion of the "Next generation of New Energy Storage Battery Technology Innovation Trends".

With the increasing industrialization of Large Cylindrical Lithium Iron, following Tesla's "4680" Large Cylindrical Battery proposed on Battery Day 2020, the global battery industry has set off a race for Large Cylindrical Batteries. Large cylindrical Batteries are starting to enter energy storage frequently, providing lower cost and better performance battery solutions for energy storage products. The Large Cylindrical Lithium Iron Phosphate Cells independently developed and produced by Topband battery Co.,Ltd are covered 33 series conventional models, 40 series fast charging models and 46 series long cycle models. Based on the good safety, lower cost and excellent performance of the product, the fully automated production line can be used to form a standard module, making it the best choice of battery for Portable Power Storage. The company has more than ten years of experience in the research and development and production of Cells, producing Square Cells in Huizhou and Nantong production bases and Pounch Cells and Large Cylindrical Cells in Ninghui production base, providing Cells’ solutions for Residential Energy Storage, Portable Power Storage, Backup Energy Storage, Industrial and Commercial Energy Storage and other products.

In 2021 Topband battery Co.,Ltd acquired Ning Hui Lithium battery Co.,Ltd, and in 2019 Ning Hui invented the NH-32138 series of Cylindrical Lithium Iron Phosphate Lithium-ion Batteries for the first time. The series has cells with long cycle life and low internal resistance of the battery. The Cylindrical Battery developed by Topband battery Co.,Ltd has two major advantages of fast charging technology and long cycle technology.

Fast charging technology refers to the creation of a multi-dimensional conductive network by coating the surface layer of the collector fluid with nanoscale conductive materials, controlling the distribution of different artificial particle sizes, mixing nanoscale superconducting agents, and using a continuous laser full-full welding process for all connections between the coil core all-pole lugs and the sink fluid, the sink fluid and the housing.

Long cycle technology means that by creating a multi-dimensional conductive network with large layer spacing, "zero" side reactions are achieved in the transport channel. The use of a full lug welding process reduces the DC internal resistance and temperature rise, and the use of a bracket ensures a gentle pressure inside the core and a tighter fit between electrode and diaphragm. A unique injection process ensures uniform infiltration and the development of an ultra-long life electrolyte.

In the material system, Topband battery Co.,Ltd is also actively exploring low-cost technology solutions, sodium technology has been successfully applied to Large Cylindrical Cells, the company's Large Cylindrical Sodium products will be available in mass production in 2023, with the improvement of energy density, Sodium Large Cylindrical cells will be able to bring more economical battery solutions for Portable Power Storage. In the future, Topband battery Co.,Ltd will continue to plough deep into the industry, with the best performance battery selection solutions to help accelerate the development of the lithium industry, and to promote the early realization of the double carbon goal.

Shenzhen Topband battery Co.,Ltd is a wholly-owned subsidiary of Shenzhen Topband Co.,Ltd(002139.SZ), a leading global intelligent control solutions provider. Focusing on Lithium Battery’s products, the company can carry out independent research and development and manufacture in the three core areas of Cells, BMS and System Integration to ensure the stability and reliability of product performance. The company is committed to becoming a world-class and trustworthy provider of Lithium Battery’s products to create a low-carbon life for users, and its products have been widely used in energy storage and small power fields worldwide.
