3DOM was featured in the Financial Times on August 9, 2020, in an article titled “Japan’s battery startups take the world beyond lithium ion.” Reporter Ten Umekumi profiles 3DOM’s activities to commercialize a lithium-metal battery by 2022 that can produce twice the amount of energy of a lithium-ion power source of similar weight, and that the performance of which has already been demonstrated.
Read an excerpt below, and check out the full article here.
“While carbon materials are currently used for the negative electrodes of most lithium-ion batteries, 3Dom uses lithium metal, which has the advantage of easily increasing a battery’s capacity to store electricity but is prone to short-circuiting and igniting.
The ignition is caused by a phenomenon in which branch-shaped crystals grow on the surface of the negative electrode due to an uneven chemical reaction. The company developed a separator that controls the phenomenon, known as dendrite. The separator has spherical holes several hundred nanometers (one nanometer is one-billionth of a meter) in diameter that are arranged in perfect order. The uniform size and orderly positions of the holes allow a uniform flow of ions and a uniform chemical reaction.”
