Blue Current

Blue Current, founded in 2014, emerged from the U.S. Department of Energy's Joint Center for Energy Storage Research with a mission to create safer batteries. Initially focused on safety, the company pivoted in 2016 to develop solid-state composite electrolytes, and by 2018, it introduced a fully dry solid-state battery featuring a high-silicon anode, known as the "silicon elastic composite" battery. Headquartered in Hayward, California, Blue Current expanded its operations in 2019 with a 22,000-square-foot facility and secured over US$30 million in funding by 2022. Multilayer cell demonstrations and pilot-scale production happened in 2023 and 2024. Blue Current works on solving four primary challenges of solid-state batteries: safety, pressure, temperature, and scalability.

Blue Current are a US-based company developing solid-state batteries utilising silicon-based anodes.

Blue Current is a North American startup which develops silicon-anode lithium-ion batteries. It describes its cell chemistry as silicon composite elastic, based on the polymer solid-state electrolyte and high silicon-content anode. This update discusses Blue Current's technology.

Blue Current is a US-based early stage startup that is working on hybrid solid electrolytes for Li-ion batteries. They claim their electrolyte has an ionic conductivity >10{^-4} S/cm at room temperature and a transference number close to unity.
