Introduction

Hiroshi Abe is a notable inventor based in Hitachi, Japan, recognized for his contributions to lithium recovery technologies. With a total of 4 patents, he has developed innovative methods that address the growing need for sustainable lithium extraction from battery waste.

Latest Patents

Abe's latest patents include a method for dissolving lithium compounds, a method for manufacturing lithium carbonate, and a method for recovering lithium from lithium-ion secondary cell scrap. The method for dissolving a lithium compound involves bringing the compound into contact with water or an acidic solution while separately feeding a carbonate ion to produce carbonic acid. This carbonic acid then reacts with the lithium compound to yield lithium hydrogen carbonate. His method for producing lithium carbonate focuses on extracting lithium from lithium-ion battery waste, which includes components containing lithium and metals such as cobalt, nickel, and manganese. This process involves a wet separation technique followed by a dissolution step where crude lithium carbonate is dissolved in a liquid while carbon dioxide gas is fed into the mixture.
