BroadBit has invented and is commercializing a new type of metallic sodium battery in two families: Hi-Energy batteries with twice the energy per weight and Hi-Power batteries with ten times the power as todays lithium-ion batteries. BroadBits Hi-Power batteries can be fully charged in as little as 5 minutes. BroadBits batteries are made with abundant and cheap raw materials (e.g. table salt) and its manufacturing process is simpler than Li-ion. With these advantages, BroadBit expects its cost per kWh to be a third that of Li-ion when in mass production. Moreover, initial tests of the technology show no detectable degradation in battery performance over 600 cycles. This is because, unlike Li-ion, there are no side reactions, dendrite formation or mechanical stress due to ion intercalation.
These innovations, if BroadBit can turn them into mass production and meet their promises, could make mobile devices lighter, faster charging and longer lasting and will finally enable low-cost, high range and convenient electric vehicles including cars, buses, bikes and even electric air planes and bring about the long awaited post combustion era of transportation. BroadBit is now scaling production of its proprietary electrolytes, anodes and cathodes and is looking for partners worldwide to assemble batteries from its components.
