Semi-solid-state battery production trials set to commence by Svolt Energy in Q4
In a significant stride for the electric vehicle (EV) industry, Svolt Energy, a leading player in battery materials, cells, and energy storage technology, has announced its advancements in semi-solid-state battery technology.
Yesterday, Svolt unveiled its second-generation Dragon Armor Battery, a ternary lithium battery designed for extended-range electric vehicles (EREVs) with a capacity of up to 65 kWh. This innovation, which is not in the battery chemistry but rather in the battery pack structure, is already in mass production.
Svolt's first-generation semi-solid batteries, with an energy density of 300 Wh/kg, have been making waves in the industry. These soft-pack batteries offer several key features and benefits, including competitive energy density, cost-efficiency, and compatibility with existing liquid battery production lines.
The batteries' energy density of 300 Wh/kg is a competitive figure for semi-solid-state technology, according to industry reports. Moreover, the production costs are below the industry average, providing a significant cost advantage. The batteries are also fully compatible with existing production lines, eliminating the need for redundant investments.
Svolt's production process involves a stacking technique to address solid electrolyte brittleness issues, resulting in yield rates exceeding 90%.
These advancements position Svolt Energy as a leader in the development of semi-solid-state battery technology. In fact, Svolt's first-generation semi-solid batteries will be supplied to BMW's Mini brand for next-generation models, with mass production planned for 2027.
Svolt's second-generation semi-solid-state batteries will have an energy density of 360 Wh/kg, a potential improvement that reflects the company's commitment to pushing the boundaries of battery technology. Future all-solid-state batteries from Svolt are targeting an energy density of 400 Wh/kg for specialized applications.
The Dragon Armor Battery also boasts impressive performance and safety features. Semi-solid-state batteries generally offer increased safety and thermal stability compared to traditional lithium-ion batteries. The new-generation Dragon Armor Battery supports 5C rate charging, enabling it to charge from 20 percent to 80 percent in just 12 minutes.
In addition, the Dragon Armor Battery with lithium iron phosphate cells could achieve a volume packaging efficiency of 76 percent and a range exceeding 800 kilometers. Those using ternary cells in the Dragon Armor Battery can exceed 1,000 kilometers in range.
Svolt Energy's trial production of semi-solid-state batteries will begin in Q4, with a capacity of 140 Ah. The company's first-generation all-solid-state batteries will have an energy density of 400 Wh/kg and will be used in low-altitude flight and automotive applications.
Svolt Energy, a spin-off from Great Wall Motor in February 2018, is poised to revolutionize the EV industry with its innovative battery technology. With its focus on battery materials, cells, modules, packs, BMS, and energy storage technology, Svolt is uniquely positioned to drive the future of electric mobility.
