This story is nearly 12 months old but seems be to close to production.
Helsinki based BroadBit has developed and is commercializing a new type of metallic sodium battery in two families:
a. Hi-Energy batteries with up to twice the energy per weight as today’s lithium-ion batteries.
b. BroadBits Hi-Power batteries can be fully charged in as little as 5 minutes.
BroadBits batteries are made with abundant and cheap raw materials and its manufacturing process is simpler than Li-ion. With these advantages, BroadBit expects its cost per kWh to be a third less than 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.
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. BroadBit is now scaling production of its proprietary electrolytes, anodes and cathodes and is looking for partners worldwide to assemble batteries from its components.
