MOST POPULAR IN ENERGY Start-ups hoping to commercialize silicon materials for battery anodes raised nearly half a billion dollars in the final quarter of 2022. The money is intended to help them build factories and incorporate their materials into mass-market electric vehicles in the next few years. Nearly all lithium-ion batteries use graphite materials in their anodes, the negatively charged ends of batteries that store lithium ions flowing from the positively charged cathodes during charging. Materials containing silicon metal can improve a battery’s energy density because they store more lithium ions than the same amount of graphite. However, silicon has proven difficult to incorporate into commercial batteries because it swells during charging, potentially causing a damaging reaction with the battery’s electrolyte. The bulk of the recent funding came in mi
