Lithium batteries are the mainstream, but may be replaced by these five batteries

Although lithium batteries are still considered to be the mainstream battery technology in the next decade, the new battery technology is actually in the process of development. In this regard, there are media forecasts for the next five major battery technologies:

1. The next generation of lithium-ion batteries

To increase battery energy density while reducing the amount of raw materials required, researchers are now improving the performance of existing lithium-ion batteries by enhancing or replacing the anode and cathode materials of the battery. According to the International Energy Agency's 2018 electric vehicle outlook, a new generation of lithium-ion batteries will be mass-produced around 2025.

2. Lithium battery

Other lithium-containing batteries are lithium-air batteries and lithium-sulfur batteries, but their technology is not yet ready, the actual application performance has yet to be tested, and whether its performance is better than lithium-ion battery performance has not been confirmed.

3. Solid state battery

Researchers have improved the degree of autopilot and extended the cruising range of electric vehicles by replacing the liquid electrolyte in current lithium-ion batteries with solid electrolytes. Solid-state lithium-ion batteries will have higher energy density and faster charging speeds, while also being safer, more reliable, and longer lasting. Many automakers (OEMs) are working on the technology, such as BMW, Hyundai and Toyota, Nissan, Honda and Panasonic to develop solid-state battery technology. Volkswagen also formed a joint venture with QuantumScape to develop solid-state batteries.

4. Hydrogen fuel cell

The most representative lithium-free energy storage technology is the hydrogen fuel cell led by Hyundai, Toyota and Honda. However, expensive hydrogen fuel cell materials have hampered the development of this technology.

5. No lithium battery

Various research teams are trying to find ways to get rid of lithium battery thinking and try various methods such as graphene supercapacitors and sodium batteries. However, it is doubtful whether such batteries can compete with lithium-ion batteries, because lithium-ion batteries are cheaper and have a good start.
