New Manganese Hydrogen Battery For Storing Electricity

A research team from Stanford University in the United States has developed a prototype of a manganese hydrogen battery for storing electricity generated by large-scale wind and solar power equipment.

The prototype of this water-based battery is only three inches high and can generate 20 milliwatts of electricity per hour. Although the current size is small and the power generation capacity is weak, the researchers believe that their equipment will expand in the future and will reach the industrial scale so that they can charge up to 10,000 cycles. Research Coordinator Yi Cui said: “We put special salt into the water and place it in the electrode to produce a reversible chemical reaction and store the electrons as hydrogen.”

Scientists use industrial salts used in the production of dry cells, fertilizers, paper and other products to reversibly exchange electrons between water and manganese sulfate. The inflowing electrons react with the manganese sulfate dissolved in the water, causing the manganese dioxide particles to adhere to the electrode, and the excess electrons generated become hydrogen gas, thereby storing this energy for future use.

Next, scientists reconnect the power supply to depleted devices to ensure that the battery can be charged. Manganese dioxide particles adhere to the electrode and combine with water to supplement manganese sulfate. "Once this salt is recovered, the incoming electrons become redundant, and the excess energy is released like hydrogen. This process can be repeated again and again.

The research team also stated that a cheaper process combining manganese sulfate and water is currently being developed.
