What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12582961B2 to L&F CO., LTD. for a novel device intended for the preparation of multi-component metal hydroxide. The patent details a system comprising a raw material feeder, a reactor for chemical reactions and particle growth, a storage tank, and an operation controller that circulates the reaction solution between the reactor and storage tank until the metal hydroxide particles reach a target size. This patent covers the specific apparatus and its operational control mechanism.

This patent grant is primarily informational for manufacturers in the chemical and battery industries. While it does not impose new regulatory obligations, it signifies intellectual property protection for L&F CO., LTD.'s technology. Companies involved in similar manufacturing processes should be aware of this granted patent, particularly if their operations involve the preparation of multi-component metal hydroxides, as it may impact their freedom to operate or potential licensing requirements.

Abstract

Disclosed is a device for preparing multi-component metal hydroxide including a raw material feeder configured to feed raw materials including a metal raw material, a pH adjuster and a complexing agent, a reactor configured to react the raw materials fed from the raw material feeder to prepare a reaction solution and grow particles of multi-component metal hydroxide contained in the reaction solution, a storage tank configured to store the reaction solution transferred from the reactor, a first duct configured to transfer the raw materials from the raw material feeder to the reactor, a second duct configured to transfer the reaction solution from the reactor to the storage tank, a third duct configured to transfer the reaction solution from the storage tank to the reactor, and an operation controller configured to control operations of the reactor and the storage tank to circulate the reaction solution between the reactor and the storage tank until the particles of multi-component metal hydroxide grow to a target particle size.
