However, for decades, researchers have investigated <a href=\"https:\/\/spectrum.ieee.org\/silicon-anode-battery\" target=\"_self\">silicon as a replacement<\/a> for this graphite. In theory, silicon offers roughly 10 times the energy density of graphite in lithium-ion batteries.<\/p>\n<p>\u201cBasically, graphite holds on to lithium using holes in its structure,\u201d says <a href=\"https:\/\/www.linkedin.com\/in\/raj-talluri-988b011\" rel=\"noopener noreferrer\" target=\"_blank\">Raj Talluri<\/a>, CEO of <a href=\"https:\/\/www.enovix.com\/\" rel=\"noopener noreferrer\" target=\"_blank\">Enovix<\/a>. \u201cIn contrast, with silicon in the anodes\u2014usually a silicon oxide or a silicon carbide\u2014lithium actually chemically combines with the silicon to form a new material. This lets a silicon-based anode hold on to much more lithium than graphite during charging. When the battery discharges, the silicon material goes back to its original state.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A novel lithium-ion battery that uses silicon in its anodes may have the highest energy density of any battery currently commercially available.
