Researchers worldwide are working on new opportunities in battery technology to promote the energy transition. Chinese researchers have now developed a lithium metal battery that promises a double energy density.
The global demand for batteries and capacity for energy storage will grow enormously in the coming years. By 2030, the demand could be forecast for more than 2,000 gigawatt hours. For comparison: In 2020 there were still 185 gigawatt hours.
This strong increase is particularly accompanied by the increasing electrification of road traffic. But the storage of fluctuations in renewable energies also drive research in battery technology.
Researchers from China have now developed a lithium metal battery that is twice as powerful as the most advanced e-car battery from Tesla. With a doubled energy density, the battery should also be safer and have a longer lifespan.
Lithium metal battery with double energy density
Chinese scientists from the Tianjin University were able to reach an enormous energy density with their new lithium metal battery. This indicates how much energy one battery can save per mass unit – for example per kilogram of weight.
The higher this energy density, the smaller and lighter batteries can be. Especially for e-mobility, this is a crucial factor for the range of electric cars.
The researchers of the Tianjin University have now developed a new lithium metal battery that has an energy density of more than 600 watt hours per kilogram. With its most powerful electric car battery, Tesla currently has 300 watt hours per kilogram.
The research results in the journal Nature Promise an improvement in the energy density of 200 to 300 percent and a significantly longer lifespan of lithium metal batteries.
New electrolyte design bypass restrictions
Pure lithium metal is used for lithium metal batteries compared to lithium-ion batteries instead of graphite. However, these are more powerful, but also more technically difficult to control.
“The practical applications of LMBS are restricted by the current electrolytic designs that are naturally dependent on dominant solvation structures,” the researchers explain in their study. This can prevent the lithium deposit from going quickly and evenly during the charging process and use.
The researchers of the Tianjin University were able to redesign this solvation environment of lithium ions in their battery. As a result, they were able to overcome the current restrictions on the electrolyte design, which now gives fewer obstacles for ion transport and thus more stability.

As a Tech Industry expert, I am impressed by China’s advancements in the development of lithium metal batteries with double the energy density. This breakthrough has the potential to revolutionize the battery industry by significantly increasing the energy storage capacity of lithium batteries, which are already widely used in various electronic devices and electric vehicles.
The increased energy density of these batteries could lead to longer battery life, faster charging times, and improved overall performance of electronic devices. This could have a significant impact on the tech industry, as it would enable the development of more powerful and efficient devices that can operate for longer periods of time without needing to be recharged.
Furthermore, the development of lithium metal batteries with double the energy density could also have a positive impact on the electric vehicle market. By increasing the range and performance of electric vehicles, these batteries could help accelerate the transition to a more sustainable transportation system.
Overall, I believe that China’s advancements in lithium metal battery technology are a promising development that could have far-reaching implications for the tech industry and the transition to a cleaner, more sustainable future. I look forward to seeing how this technology evolves and how it will be adopted by manufacturers and consumers in the coming years.
