The performance and price of lithium batteries have always been the focus of consumers' concern, especially after experiencing the impact of safety reports such as Tesla's electric car on fire.

　　So, what are the batteries that can replace the existing lithium battery system in the future?

　　Type 1: no lithium battery

　　Various research teams try to use graphene, supercapacitors and sodium batteries to replace existing lithium batteries. However, whether such batteries can compete with lithium-ion batteries is still doubtful, because lithium-ion batteries have a lower cost and have already had a good start for development.

　　Type 2: solid state battery

　　The solid-state battery is essentially a new type of battery formed after the liquid electrolyte and separator of the traditional lithium-ion battery are replaced with a solid electrolyte.

　　Researchers have extended the range of electric vehicles by replacing liquid electrolytes with solid electrolytes. Solid-state lithium-ion batteries will have higher energy density and faster charging speed, but also safer, more reliable, and longer life.

　　Type 3: hydrogen fuel cell

　　Hydrogen fuel cell is a battery that uses hydrogen, a chemical element, that can store energy. This kind of battery is pollution-free, noise-free, and highly efficient, and is widely used in the aerospace field and automotive energy.

　　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 hindered the development of this technology.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries and are the first choice in the energy storage industry.
