Hengjia high-purity boehmite reaches full production and enters the lithium battery market

Zouping Hengjia New Materials Technology Co., Ltd. (referred to as "Hengjia Technology") is a wholly-owned subsidiary of Shandong Hengjia High Purity Aluminum Technology Co., Ltd. It was established in 2020 and mainly produces tabular corundum, boehmite, etc.

Hengjia Technology's boehmite products have achieved large-scale production, with a total boehmite production capacity of 10,000 tons/year. They have excellent performance and good stability, and customers are very satisfied with them after using them. Sales have increased rapidly, and the delivery pressure is relatively high. In order to cope with the current rapid increase in market demand, another production line with a capacity of 10,000 tons/year is under construction and is scheduled to be put into production next year.

Boehmite has a lower hardness than alumina, a narrower particle size distribution, weaker water absorption, and is easier to keep the diaphragm dry. It also has high coating flatness, low internal resistance, and low energy consumption. It can improve the high temperature resistance, heat shrinkage resistance, and puncture strength of the diaphragm, thereby improving battery safety. It also has better liquid absorption and retention properties, which can increase battery life. Therefore, the proportion of boehmite used in the lithium battery market is also increasing rapidly.

The proportion of boehmite used in inorganic coatings of diaphragms will increase from 55% in 2021 to 70% in 2025. The demand for boehmite will usher in high growth, and Hengjia Technology will also enter the lithium battery market.
