A comprehensive investigation by battery researcher Ziroth has revealed that Donut Lab’s “miracle” solid-state battery is actually a lithium-ion cell. The company raised approximately $25 million from over 1,300 mostly small investors based on claims that now appear to be false. This exposé has significant implications for the battery industry, as it highlights the importance of transparency and honesty in the development and marketing of new battery technologies. The investigation involved over 20 independent battery experts and provides definitive proof that Donut Lab’s battery is not solid-state, but rather a lithium-ion cell. Electrek

US-based solid-state battery maker Factorial Energy has debuted on the Nasdaq stock exchange after achieving a significant milestone in the development of its solid-state batteries. The company’s batteries have already proven capable of delivering over 745 miles (1,200 km) of real-world driving range. This achievement demonstrates the potential of solid-state batteries to revolutionize the electric vehicle industry. Factorial Energy is now tapping into public markets to fund its next phase of growth, which is expected to further accelerate the development and commercialization of its solid-state battery technology.

Lithium-air batteries may offer a new solution for long-term energy storage, according to a recent article. These batteries have the potential to provide higher energy density and longer cycle life than traditional lithium-ion batteries, making them an attractive option for applications such as grid-scale energy storage. While still in the early stages of development, lithium-air batteries could play a significant role in the transition to a more sustainable and renewable energy-based economy. 36氪Web
