Chinese battery maker, Sunwoda, recently revealed their groundbreaking progress in developing all-solid-state batteries. This innovative technology is expected to significantly reduce the cost of battery production. Sunwoda predicts that by 2026, the cost of their polymer-based all-solid-state batteries could be as low as RMB 2 ($0.275) per Wh, putting it on par with semi-solid-state batteries.
Solid-state batteries have been gaining popularity in China ever since Nio, the electric vehicle manufacturer, announced their 150-kWh semi-solid-state battery. Although the technology is promising, the high cost of production has been a major challenge. However, Sunwoda’s breakthrough could change the landscape of the industry.
With an energy density of 360 Wh/kg, Nio’s semi-solid-state battery offers impressive performance. However, it comes at a steep cost, with production prices comparable to Nio’s ET5 sedan, which starts at RMB 298,000. Sunwoda’s goal of reducing the cost of all-solid-state batteries to around RMB 300,000 by 2026 could open up new possibilities for electric vehicle manufacturers and consumers alike.
Sunwoda’s accomplishments in all-solid-state battery development are remarkable. They have already created batteries with capacities up to 20 Ah and energy densities exceeding 400 Wh/kg. The company is now working towards building a production line with a capacity of up to 1 GWh by 2026, paving the way for mass production.
Additionally, Sunwoda is pushing the boundaries of energy density further by incorporating lithium metal into the negative electrode. This enhancement could increase the energy density of solid-state batteries to an astonishing 500 Wh/kg. Furthermore, they aim to achieve lab samples with energy densities surpassing 700 Wh/kg by 2027.
The advancements made by Sunwoda in all-solid-state battery technology have the potential to revolutionize the electric vehicle industry. Not only will the cost of production decrease significantly, but the energy density of batteries will also improve, leading to greater efficiency and longer driving ranges. These developments are undoubtedly exciting, and electric vehicle enthusiasts can look forward to a more accessible and sustainable future.
