Recently, Mercedes-Benz said it will invest $8 billion in hybrid vehicle development and manufacturing in the next two years, and will develop a new "lithium-magnesium" fuel cell technology to replace lithium-ion batteries currently used. Mercedes-Benz said that battery technology will make a great leap forward in the future. At present, lithium-magnesium batteries have the best development prospects. In the next 10 years, it will introduce new fuel cells that can replace lithium-ion batteries.

Analysts believe that the limited capacity of batteries has become a serious bottleneck in the development of smartphones and wearable devices. Magnesium batteries are one of the frontiers of scientific research. Magnesium air reserve batteries can work for 30 days with a 10-watt LED lamp or charge 200 smartphones. Magnesium storage battery can be used for more than 10 years. It can be activated by adding fresh water or sea water in any occasion for temporary use. It can be used within half an hour after activation. In view of the unique advantages of magnesium reserve battery, its popularization in the future will hopefully lead to the growth of magnesium demand.
