A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
2 and manganese dioxide spinels through omission of the cobalt, whose negative temperature coefficient of resistance can encourage thermal runaway. The P–O bond in the (PO 4) 3− ion is stronger than the Co–O bond in the (CoO 2) − ion, so that when abused (short-circuited, overheated, etc.), the oxygen atoms are released more slowly ...
