Tian Tie Technology Secures 400 Million Yuan Order for Lithium Metal Solid-State Battery Materials

Recently, Tiantie Technology announced that its indirect subsidiary, Anhui Tiantie, has signed a "Procurement Framework Agreement" with Zhuhai Xinjie Energy Technology Co., Ltd. (hereinafter referred to as "Zhuhai Xinjie").Zhuhai Xinjie plans to purchase copper-lithium composite strips from Anhui Tiantie, with an order amount of 400 million RMB and an order quantity of 100 tons.

The copper-lithium composite tape is a strip material composed of an anode current collector (copper foil) and an anode active material (lithium metal foil) through a specific process. It combines the advantages of copper's conductivity and mechanical strength with lithium's electrochemical activity.Common solutions for lithium metal anodes. This material is mainly used in the field of lithium metal solid-state batteries.

The announcement mentioned that Zhuhai Xinjie is a wholly-owned subsidiary of Xinjie Energy, which is a company focused on the research and production of lithium metal solid-state batteries. Tiantie Technology stated that Xinjie Energy has already established a lithium metal solid-state battery production line with a capacity of hundreds of MWh and is currently constructing a GWh-level production line, attracting investments from multiple investment institutions and demonstrating strong contractual performance capabilities.

Battery China has noticed that Tiantie Technology signed a strategic cooperation framework agreement with Xinjie Energy in May of this year, agreeing to...The first production line with a solid-state battery energy density of ≥450Wh/kg and a capacity of 2GWh has been put into operation.Tian Tie Technology will be responsible for supplying lithium metal materials for this production line. In principle, Xin Jie Energy will purchase no less than 100 tons annually, with a procurement period of no less than five years after production begins.

According to Tiantie Technology, preliminary estimates indicate that...About 100 tons of lithium metal anode material are required for 1 GWh of capacity.The specifics will be determined after the commissioning of XinJie Energy's 2GWh production line.

All-solid-state batteries using lithium metal as the anode material are one of the key development directions in solid-state batteries. To date, numerous companies in the lithium battery industry chain, both domestically and internationally, such as CATL, EVE Energy, Tianqi Lithium, SES, Tailan New Energy, Anhui Mengwei, Sunwoda, LG Energy Solution, SK On, as well as several automotive companies including Geely, SAIC, General Motors, Honda, and Hyundai, are actively investing in lithium metal batteries.

High energy density is a significant advantage of lithium metal solid-state batteries; however, it is worth noting thatManufacturing lithium metal batteries is highly technically challenging.According to industry insiders, due to the limitations of lithium metal anode preparation technology, the significant volume changes of lithium metal anodes, and micro-short circuits in lithium metal batteries, there is still a long way of research and exploration before lithium metal batteries can be mass-produced and applied.

Due to the highly reactive chemical nature of metallic lithium, it demands particularly high standards in manufacturing, technology, equipment, and environmental conditions. TMT Technology has revealed that Anhui TMT is equipped with advanced technology and equipment integration, including efficient electrolysis, impurity removal and purification, and low-temperature distillation, and that all product equipment is non-standard.Safe production of battery-grade metallic lithium with a purity of 99.97%-99.98%.
