Enpower Greentech has successfully developed a 100Ah lithium metal battery (LMB), another important step in the commercialization of next-generation electric vehicle batteries. In 2021, the company has developed ultra-high energy density (450Wh/kg and 520Wh/kg) lithium metal batteries, which will receive a safety certificate in June 2022.
The company's high-capacity battery cells feature a proprietary flame-retardant electrolyte solution that improves safety without compromising performance. The weight of a single cell is 0.821kg. The capacity of the cell is 102.4Ah (0.1C discharge), the weight energy density is 479Wh/kg, the volume energy density is 910Wh/L, and the internal resistance is ≤1.0mΩ. In addition, the cell has a low self-discharge rate (K value ≤2.0 μV/h at 30% SOC), which is lower than 10% of that of conventional lithium-ion batteries based on graphite and silicon anodes.
With subsidiaries in China, Japan and the US, Enpower Greentech aims to gain a competitive advantage through cross-border cooperation in the development of next-generation batteries. The company has expanded its product line to develop 10-50Ah lithium metal batteries for the drone and electric aircraft (eVTOL) markets. In addition, Enpower Greentech is also developing an all-solid-state lithium metal battery and plans to deliver Ah-class pouch cells for external testing by the end of this year. The company plans to start production of 100MWh and GWh lithium metal battery production lines in 2023 and 2024, respectively.
Many multinational automakers and battery makers are now competing in the battery space, the core technology that drives the global industry. Founded 10 years ago, Enpower Greentech has developed into a global technology leader, especially in battery performance such as energy density and cycle life. In the future, Enpower will continue to improve battery performance, optimize performance indicators such as cycle life and fast charging, while reducing costs.
