High-purity Alumina (HPA) for Lithium-ion Batteries Market Description
High-purity aluminum oxide is often termed as High-purity alumina. It is a white, granular, chemical produced commercially either by treating aluminum with specific chemicals or by the use of other aluminous feed stock. Some of the commonly used processes for high-purity alumina production include alkoxide process, thermal decomposition process, choline hydrolysis process, and modified Bayer process. 4N, 5N, and 6N grades of high-purity alumina are extensively used for lithium-ion batteries.
High-purity alumina is used as a coating on lithium-ion battery separators. Lithium-ion batteries with high-purity alumina coated separator are extensively used in mobile electronic devices such as smartphones, laptops, smart wearable devices, media players, and smart speakers. Lithium-ion batteries are a preferred source of power for mobile devices due to their compact size and high stability. Increasing requirement for these batteries in developing economies is anticipated to drive demand for high-purity alumina for lithium-ion batteries in the near future.
Rising Demand for High-purity Alumina in Lithium-ion Batteries Separator Coatings to Fuel Market
- A lithium-ion battery is composed of a positive electrode, negative electrode, electrolyte, and battery separator. The quality of the battery separator determines the battery’s safety and service life, as it accounts for 40% of the total cost of battery production.
- High-purity alumina is used as a coating on the separator sheet. This plays an important role in increasing the separator’s life cycle, as it provides certain benefits such as high thermal stability, chemical stability, long life cycle, and high heat shrink ability.
- High-purity alumina-coated lithium-ion batteries are much safer than traditional batteries as they can withstand high temperature incursions and are less flammable during thermal runaways. Additionally, high-purity alumina coated lithium-ion batteries possess low self-discharge rate, high battery discharge rate, and high life cycle.
- These benefits of high-purity alumina make it a favorable choice of material for battery separator coatings and are anticipated to drive the high-purity alumina market for lithium-ion batteries. Demand for lithium-ion batteries is rising in various short duration applications such as peak load management, renewable integration, as it improves performance of lithium-ion batteries.
