Various materials have been studied in order to develop varieties with better performance. Thus creating unprecedented products. For example, lithium sulfur dioxide batteries and lithium thionyl chloride batteries are very characteristic. Their positive active material is also a solvent for the electrolyte. This structure can only appear in the electrochemical system of non-aqueous solution. Therefore, the research on lithium batteries has also promoted the development of the electrochemical theory of non-aqueous systems. In addition to using various non-aqueous solvents, studies on polymer thin film batteries have also been conducted.

Lithium batteries are widely used in energy storage power systems such as hydraulic power, thermal power, wind power and solar power plants, uninterruptible power supplies for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.

Lithium-ion batteries have been widely used in portable electrical appliances such as laptops, cameras, and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources of electric vehicles in the 21st century, and will be applied in artificial satellites, aerospace and energy storage. With the shortage of energy and the pressure of the world's environmental protection. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of the lithium battery industry.

The introduction of the "Plan" is expected to change the world's lithium battery pattern

On April 18, the State Council discussed and approved the "Development Plan for Energy Conservation and New Energy Automobile Industry (2012~2020)" (hereinafter referred to as the "Plan"), which clarified the main strategic orientation of pure electric drive as the transformation of the automobile industry, and promoted the popularization of non Plug-in hybrid electric vehicles, and put forward the goal of cumulative production and sales of pure electric and hybrid electric vehicles reaching 500,000 units in 2015, and exceeding 5 million units by 2020.

The introduction of the "Plan" has aroused great concern in the market. Many experts believe that this move will promote the automobile industry to enter a new round of development. In addition, it will virtually outline a huge market outline for the power battery industry, the core component of energy-saving and new energy vehicles.

In November 2022, researchers at the Massachusetts Institute of Technology explained the reasons for the formation of "dendrites" in rechargeable lithium batteries and how to prevent them from passing through the electrolyte. The discovery could eventually open the door to the design of a new type of rechargeable lithium battery.
