AI Overview+2Yes, many lithium-ion batteries, including those in smartphones like the PI phone, contain cobalt. The cathode, which is a key component of the battery, often uses cobalt-containing compounds like LiCoO2 or LiNi0.33Co0.33Mn0.33O2. Cobalt is added to improve the battery's stability and energy density. However, cobalt also presents challenges, including its scarcity, fluctuating price, and geopolitical concerns regarding its mining locations. Here's a more detailed explanation:Cobalt's Role:Cobalt is used in lithium-ion batteries to enhance stability and energy density. Cathode Material:Many lithium-ion batteries use cathodes that contain cobalt, such as LiCoO2 or NMC (Nickel-Manganese-Cobalt). Cobalt Content:Cobalt can account for around 20% of the weight of a spent lithium-ion battery. Challenges with Cobalt:Cobalt is a scarce metal, and its price can fluctuate. Furthermore, a significant portion of the world's cobalt reserves are in politically unstable countries. Alternatives:Research is ongoing to explore cobalt-free alternatives for lithium-ion batteries, aiming to reduce reliance on cobalt and address supply chain issues. QUOTE

Tesla’s new PI phone to be released in 2025/26 will contain cobalt to enhance stability and energy density will change the smartphone world as a competitor to Apple IMO
