Lithium batteries are a class of batteries made of lithium metal or lithium alloys that use non-aqueous electrolyte solutions, which can be roughly divided into two categories: lithium-ion batteries and lithium metal batteries. What we usually call lithium batteries are lithium-ion batteries, which mainly rely on the movement of lithium ions between positive and negative electrodes.

In 1991, Sony put lithium-ion batteries on the market, officially opened the commercial era of lithium batteries, promoted the appearance innovation of consumer electronics, and fundamentally improved the way people store and use energy.

After years of development, lithium batteries have become the most widely used and promising batteries in the world today. In the automotive industry, the development of new energy vehicles is in full swing, and the trend of lithium-ion batteries becoming mainstream energy storage technologies is becoming more and more obvious; in the medical industry, lithium batteries are widely used in pacemakers; in the field of aerospace, lithium batteries support launch, flight correction, ground operation and night operations; in daily life In terms of lithium battery applications can be seen everywhere, ranging from mobile phones, laptops, digital cameras, electric tools, etc. to emergency power supplies in factories, schools, hospitals and other places.

China has obvious advantages in lithium battery manufacturing. In 2021, the global lithium-ion battery market size was 545GWh, China's lithium-ion battery shipments were 324GWh, accounting for about 59.4% of the global market.

In the process of the production of cathode materials for lithium batteries, it is strictly forbidden to contain metal elements such as copper (Cu) and zinc (Zn) in relevant pipes and valve materials. If there are metal impurities such as copper (Cu) and zinc (Zn) in the materials, these metals will first be positively oxidized and then reduced to the negative electrode. When the metal element at the negative pole accumulate to a certain extent, the hard edges and corners of the deposition metal will puncture the diaphragm, causing the battery to be self-discharged. Self-discharge will bring potential safety hazards and even cause explosion accidents.

Runjing ceramic hard sealing ball valve adopts a good wear resistance and corrosion resistant ceramic valve core, and the valve body is made of engineering plastic or 316L stainless steel. After strict testing, it does not contain copper (Cu) and zinc (Zn) elements, which can better meet the production process requirements of lithium electrode materials. It has been applied in large quantities in the lithium battery industry, and various performance indicators have been affirmed by customers.
