You think? Do you NEVER just look anything up?
Rechargeable lithium ion batteries are made with lithium and potassium or lithium and cobalt. No magnesium.
And if you want to see something burn, put lithium into contact with water.
The reporter says magnesium, I will take the Fireman's word over yours.
LOL Ms. Elektra still doesn't know her ass from a hole in the ground.
Materials and Processing for lithium-ion Batteries
Cathode Materials
State-of-the-art cathode materials include lithium-metal oxides [such as LiCoO2, LiMn2O4, and Li(NixMnyCoz)O2], vanadium oxides, olivines (such as LiFePO4), and rechargeable lithium oxides.11,12 Layered oxides containing cobalt and nickel are the most studied materials for lithium-ion batteries. They show a high stability in the high-voltage range but cobalt has limited availability in nature and is toxic, which is a tremendous drawback for mass manufacturing. Manganese offers a low-cost substitution with a high thermal threshold and excellent rate capabilities but limited cycling behavior. Therefore, mixtures of cobalt, nickel, and manganese are often used to combine the best properties and minimize the drawbacks. Vanadium oxides have a large capacity and excellent kinetics. However, due to lithium insertion and extraction, the material tends to become amorphous, which limits the cycling behavior. Olivines are nontoxic and have a moderate capacity with low fade due to cycling, but their conductivity is low. Methods of coating the material have been introduced that make up for the poor conductivity, but it adds some processing costs to the battery.
Anode Materials
Anode materials are lithium, graphite, lithium-alloying materials, intermetallics, or silicon.11 Lithium seems to be the most straight forward material but shows problems with cycling behavior and dendritic growth, which creates short circuits. Carbonaceous anodes are the most utilized anodic material due to their low cost and availability. However, the theoretical capacity (372 mAh/g) is poor compared with the charge density of lithium (3,862 mAh/g). Some efforts with novel graphite varieties and carbon nanotubes have tried to increase the capacity but have come with the price of high processing costs. Alloy anodes and intermetallic compounds have high capacities but also show a dramatic volume change, resulting in poor cycling behavior. Efforts have been made to overcome the volume change by using nanocrystalline materials and by having the alloy phase (with Al, Bi, Mg, Sb, Sn, Zn, and others) in a nonalloying stabilization matrix (with Co, Cu, Fe, or Ni). Silicon has an extremely high capacity of 4,199 mAh/g, corresponding with a composition of Si5Li22. However, cycling behavior is poor, and capacity fading not yet understood.
