The phone battery has been charged for more than a week, and it only takes 15 minutes to charge each time. Researchers at Northwestern University in United States have brought us one step closer to that dream. According to a report by the United States Physicists Organization Network on November 15 (Beijing time), engineers at the university have developed an electrode for lithium-ion batteries, allowing the battery to retain 10 times more power than the existing technology, and can increase the charging rate of batteries with new electrodes by 10 times. The study was published in the recent issue of the journal Advanced Energy Materials. Storage capacity and charging rate are two important battery limitations. The amount of stored power is limited by the charge density, which is how much lithium can be held at the two poles of the battery. The charging rate is limited by the speed at which lithium ions can reach the negative electrode from the electrolyte.
The negative electrode of existing lithium-ion batteries is made of carbon-based graphene sheets, and one lithium atom can only fit six carbon atoms. In order to increase the amount of stored electricity, scientists have tried to use silicon instead of carbon, so that silicon can adapt to more lithium, so that 4 lithium atoms correspond to 1 silicon atom. However, silicon expands and shrinks significantly during charging, causing rapid cracking and loss of charging capacity. The shape of the graphene sheets also restricts the charging rate of the battery, and although they are only one carbon atom thick, they are very long. Since it takes a long time for lithium to move to the middle of the graphene sheet, ionic traffic jams often occur at the edges of the graphene sheet.
Now, the research team has solved these problems by combining two technologies. First, in order to stabilize the silicon to maintain the maximum charging capacity, they added silicon clusters between the graphene sheets, and used the elasticity of the graphene sheets to cooperate with the change in the number of silicon atoms in the use of the battery, so that a large number of lithium atoms were stored in the electrodes. The addition of silicon clusters results in higher energy density while also reducing the loss of charging capacity due to silicon expansion and shrinkage, giving you the best of both worlds.
The team also used a chemical oxidation process to create 10 nanometer to 20 nanometer micropores on the graphene sheet, known as surface defects, so that lithium ions will follow this shortcut to the negative electrode, where they will react with silicon and store at the negative electrode. This will reduce the charging time of the battery by a factor of 10.
