【You might want to know】What Lithium ion batteries are made of?

A type of a battery composed of Lithium, the lightest metal and the metal that has the highest electrochemical potential. Lithium, however, is an unstable metal, so Lithium-Ion batteries are made from Lithium ions from chemicals. Because of its lightness and high energy density, Lithium-Ion batteries are ideal for portable devices, such as notebook computers. In addition, Lithium-Ion batteries have no memory effect and do not use poisonous metals, such as lead, mercury or cadmium. The only disadvantage to Lithium-Ion batteries is that they are currently more expensive than NiCad and NiMH battery packs.

Lithium-ion batteries are common rechargeable batteries for portable electronics, with a high energy density, no memory effect (other than LFP cells)^[9] and low self-discharge. LIBs are also growing in popularity for military, battery electric vehicle and aerospaceapplications.^[10]

Chemistry, performance, cost and safety characteristics vary across LIB types. Handheld electronics mostly use LIBs based on lithium cobalt oxide (LiCoO
₂), which offers high energy density but presents safety risks,^[11] especially when damaged. Lithium iron phosphate (LiFePO
₄), lithium ion manganese oxide battery (LiMn₂O₄, Li₂MnO₃, or LMO), and lithium nickel manganese cobalt oxide (LiNiMnCoO₂ or NMC) offer lower energy density but longer lives and less likelihood of fire or explosion. Such batteries are widely used for electric tools, medical equipment, and other roles. NMC in particular is a leading contender for automotive applications. Lithium nickel cobalt aluminum oxide (LiNiCoAlO₂or NCA) and lithium titanate (Li₄Ti₅O₁₂ or LTO) are specialty designs aimed at particular niche roles. The newer lithium–sulfur batteries promise the higher performance-to-weight ratio.

Lithium-ion batteries can be a safety hazard since they contain a flammable electrolyte and may become pressurized if they beome damaged. A battery cell charged too quickly could cause a short circuit, leading to explosions and fires.

They start degrading as soon as they leave the factory. They will only last two or three years from the date of manufacture whether you use them or not.
They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would.
If you completely discharge a lithium-ion battery, it is ruined.
A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
There is a small chance that, if a lithium-ion battery pack fails, it will burst into flame.
