Alsym Energy, a startup focused on innovating in the energy storage sector, has successfully raised $78 million in Series C funding to develop batteries that do not rely on lithium. This move comes in response to the slow decline in battery costs and the search for more accessible and abundant materials to make energy storage widely available. Researchers at the Massachusetts Institute of Technology (MIT) are at the forefront of this development, working on batteries made from cost-effective and abundant materials.
