Chloride Content of Cathode Material Used in Lithium-ion Batteries Lithium-ion batteries are typically installed for use in portable electronic devices and electric vehicles (EVs). They are a popular choice due to their high energy density as they are both powerful and lightweight. Lithium ions are found in both the cathode and anode material of lithium-ion batteries. The everyday commonplace battery type utilizes lithium graphite (LiC 6) as anode and lithium cobalt oxide (LiCoO 2) as a cathode. The manufacture of cathode materials generally includes a calcination step. The solid precursor s...
