Search for the Super Battery . The topic is of intense interest to me, as the development of better, cheaper batteries is critical for both the future of electric vehicles (EVs) and for the future electrical grid. Battery improvements are needed to increase the range of EVs, and cheaper batteries can help drive down the costs of EVs so more consumers can afford them. For the electrical grid, increased penetration of renewables poses some challenges because of their intermittent nature. Since the wind could stop blowing at any time, and the sun’s radiation can only be captured during the day, these sources of power need to be backed up. Cost-effective storage of power could enable essentially unlimited penetration of renewables into the grid. Thus, tremendous effort has gone into battery development in recent years. The effort is paying off, with prices for battery cells falling by 70 percent between […]
