lithium manganate
is that it is relatively safe, cheap and reasonable. The disadvantage is that the cycle life is not as long as ternary lithium and lithium iron phosphate, and the high temperature resistance is poor. When the battery is exposed to high temperature, it is easy to decompose, and trivalent manganese becomes divalent manganese. The advantages of
ternary lithium
are easy mass production and high energy density, that is, the energy contained in unit volume or unit weight is relatively high. The disadvantages are unstable security, high activity, and poor stability. The advantage of
lithium iron phosphate
is that a single-cell lithium iron phosphate has a long life, the cycle number can reach 3000 times, and the safety is good. The disadvantage is that when the capacity difference is made into a battery pack, matching is relatively difficult, the material or process stability is not enough, and its low-temperature characteristics are poor.
