A new battery technology has been developed for electric vehicles in China. The battery system called Li-H offers an energy solution that uses hydrogen as the anode. This system, which is based on the use of hydrogen instead of lithium, can reach a remarkable theoretical energy density of 2825 Wh/kg.

There will be a battery revolution in electric vehicles

While hydrogen usually serves as the cathode in traditional hydrogen batteries, Chinese researchers have reversed this approach and used hydrogen as the anode. Thanks to this innovative structure, a constant operating voltage of approximately 3 volts was achieved and the energy density was significantly increased.

One of the striking aspects of the new system was the 99.7 percent efficiency achieved. The fact that energy can be almost completely preserved during charging and discharging processes both minimizes energy loss and provides high productivity during use.

The team also designed an alternative version that does not include an anode in order to make the battery system they developed safer, more economical and suitable for production. With this method, 98.5 percent Coulombic efficiency was achieved and the system was able to operate stably even at low hydrogen levels.

The high energy density and efficiency offered by Li-H batteries could go beyond traditional nickel-hydrogen batteries and revolutionize areas such as long-range electric vehicles, aviation applications, and large-scale renewable energy plants.
