According to statistics from China Chemical and Physical Power Supply Industry Association， China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year. 

From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of chromium oxide, led by lithium-ion batteries, is expected to expand globally. 

What is Chromium Oxide?
Chromium oxide is an inorganic substance. Chromium oxide chemical formula is Cr2O3. It is a light green to dark green fine hexagonal crystal. It turns brown when it is hot and green when it is cold.
Cr2O3 exists in chromium-rich tremolite skarn, post-quartz and chlorite veins in the form of natural mineral eskolaite. Eskolaite is also a rare component of chondrite.
 
Chromium Oxide Properties
Cr2O3 has a corundum structure and is composed of hexagonal arrays of oxide anions, in which 2 / 3 of the octahedral holes are occupied by chromium. Similar to corundum, Cr2O3 is a hard and brittle material (Morse hardness 8-8.5).
Chromium oxide dissolves in hot alkali metal bromate solution. Soluble in heated potassium bromate solution, slightly soluble in acids and bases, almost insoluble in water, ethanol, acetone, acids and bases. And irritating. It is extremely stable to light, atmosphere, high temperature and corrosive gases such as sulfur dioxide and hydrogen sulfide. It has a high hiding power.
 
What is Chromium Oxide Used for?
1. Lead-chrome green is the main coloring pigment in the paint industry, and most of the green paints are prepared with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Because there is chrome yellow in the composition, pay attention to the toxicity of lead in its application. Lead chrome green contains iron blue and oxidizer lead chromate, so when dust encounters spark, it is possible to self-ignite, so be careful when drying and crushing. After burning, the lead-chrome green completely loses the characteristics of the green pigment and is transformed into a dark brown-yellow substance. In addition, in the production of nitro paint, the rolling process is not directly rolled with lead-chrome green, but adjusted after grinding with lead-chromium green to prevent burning during rolling.

2. It is used in metallurgy, as well as ceramics, chromium oxide refractory, raw materials for pigment industry and organic synthesis catalyst.

3. Used as analytical reagent, catalyst.

4. Used as a colorability, wear resistance and corrosion resistant filler for adhesives and sealants. It can also be used as a colorant for enamel, ceramic, artificial leather and building materials, organic chemical synthesis catalyst, sun-resistant paint and special ink for printing paper money.

5. Used as a colorant for cosmetics, mainly used in eye cosmetics, but not in oral and lip cosmetics, not recommended for facial cosmetics and nail polish.

6. Chromium oxide is one of the main components of silver plating brightening solution, and the newly prepared chromium trioxide is an important raw material for the preparation of chromium fluoride and chromium bromide.
