Driven by national policies, my country’s lithium thionyl chloride battery (lithium sub-battery) market continues to grow

Lithium thionyl chloride battery (Li/SOCl2), referred to as lithium sub-battery, refers to a lithium battery with metallic lithium as the negative electrode, carbon as the positive electrode, and anhydrous lithium tetrachloroaluminate thionyl chloride solution as the electrolyte. Lithium thionyl chloride batteries have the advantages of wide operating temperature range, high energy density, long storage life, and good safety. They are widely used in aerospace, oil drilling, medical, instrumentation and other fields.

The electrolyte of lithium thionyl chloride battery is thionyl chloride solution. Thionyl chloride solution is a colorless liquid with a pungent odor. It is an inorganic compound and is widely used in chemical industry, pesticides, medicine and other fields. Thionyl chloride is the main raw material of thionyl chloride solution. It is mostly made by sulfur dioxide gas phase process. It has the advantages of high activity and good safety, and is an important chlorinating agent. At present, my country’s thionyl chloride industry as a whole is in short supply, which has led to an increase in the production cost of lithium thionyl chloride batteries.

Lithium thionyl chloride batteries are widely used in aerospace, oil drilling, medical, instrumentation and other fields. In the field of aerospace, lithium thionyl chloride batteries can be used in aviation satellites, spacecraft and aircraft; in the field of oil drilling, lithium thionyl chloride batteries can be used in oil field testers, oil field temperature measurement equipment, etc.; in the medical field, lithium thionyl chloride batteries Acid chloride batteries can be used in medical devices such as pacemakers and defibrillators. According to the “2023-2028 China Lithium Thionyl Chloride Battery (Lithium Sub-Battery) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center ” shows that benefiting from strong application demand, my country’s lithium thionyl chloride battery market continues to grow, reaching 630 million yuan in 2022, a year-on-year increase of 7.8%.

On July 14, 2023, the National Development and Reform Commission released the “Guidance Catalog for Industrial Structural Adjustment (2023 Edition, Draft for Comments)”. The document lists lithium thionyl chloride batteries, lithium iron disulfide batteries, sodium-ion batteries, lithium-ion batteries, lead New batteries such as carbon batteries are included in the catalog of encouraged light industries. It is expected that in the future, driven by national policies, the prosperity of my country’s lithium thionyl chloride battery industry will further improve.

Attracted by market prospects, the number of companies in my country’s lithium thionyl chloride battery industry continues to grow. Yiwei Lithium Energy, Penghui Energy, Ruiyi Group, etc. are representative companies of lithium thionyl chloride batteries in my country. Yiwei Lithium Energy occupies a large share of my country’s lithium thionyl chloride batteries, and its independently developed products were successfully selected as “National Manufacturing Single Championship Products”.

Industry analysts said that lithium thionyl chloride battery, as a new type of battery, has broad application prospects in many fields. As maturity increases, my country’s lithium thionyl chloride battery market space will further expand. It is expected that in the future, driven by positive factors such as national policy support, my country’s lithium thionyl chloride battery industry will gradually develop in the direction of high performance and high quality.
