Title: Tadaaki Tanii: Innovator in Battery Recycling Technologies

Introduction

Tadaaki Tanii is a notable inventor based in Takasago, Japan. He has made significant contributions to the field of battery recycling, holding a total of 4 patents. His innovative methods focus on the efficient classification and recovery of valuable materials from used batteries.

Latest Patents

One of Tanii's latest patents is a "Method and apparatus for classifying and recovering the main components of used batteries." This invention involves a system where batteries are conveyed on a conveyor while an alternating magnetic field of multiple frequencies is applied. A detection means identifies the induced magnetic field resulting from the eddy current in the battery. The orthogonal components of this induced magnetic field are detected and compared with a pre-existing database, allowing for the continuous sorting of large quantities of used batteries. This method ensures a smooth feed and enhances the accuracy of detection.

Another significant patent is the "Method for crushing cell," which provides a safe and efficient way to dismantle used lithium-ion batteries. In this process, the plastic cases protecting the sealed battery cells are removed reliably. The batteries are chilled to temperatures of -50°C or lower and subjected to vibration and pressure, leading to the separation of valuable materials such as lithium cobalt oxide, aluminum, and copper. The sealed battery cells are then heated in a non-oxidizing atmosphere to separate organic materials, followed by a sequential separation of targeted valuable materials.
