Lithium-Ion Battery Chemistries

Sean White‘s Solar and Energy Storage Podcast

Sean is recording this podcast from Australia where he is about to teach a utility-scale battery energy storage systems (BESS) course for CPD International. This is some of the material that will be included in the course. In this podcast, we will go over different battery chemistries, focusing on the three main types of lithium-ion batteries used these days, which include: 1. Lithium Iron Phosphate (aka LFP or LiFePo or LiFePo4) 2. Lithium Nickel Manganese Cobalt Oxide (aka NMC or NCM) 3. Lithium Nickel Cobalt Aluminum Oxide (aka NCA) We will talk about the availability of these elements on Earth, the toxicity of them, we will compare and contrast to lead-acid and nickel iron batteries and we will take a dive into the controversial Cobalt, which is said to have a supply chain where child labor is often used in the Congo. Australia does lithium and cobalt mining, which is part of the solution, however the use of cobalt free lithium-ion batteries, which means LFP seems to be the solution, however the batteries with cobalt do have a higher specific energy (not to be confused with energy density). Specific energy = energy per weight (most important for EVs) Energy density = energy per volume For more go to www.solarSEAN.com or take an energy storage class at www.heatspring.com/sean Thanks for listening!!
