What's The Difference Between Different Types Of Lithium-ion Batteries?
Jul 27, 2018

We often talk about ternary lithium batteries or iron-lithium batteries, which are named after the positive active material. As we all know, the specific parameters of the batteries of the same technical route are not exactly the same, and the following content shows the general level of the current parameters. The six lithium batteries specifically include: lithium cobalt oxide (LiCoO2), lithium manganate (LiMn2O4), lithium nickel cobalt manganese oxide (LiNiMnCoO2 or NMC), lithium cobalt aluminum aluminate (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4) , lithium titanate (Li4Ti5O12).

1.Lithium cobalt oxide (LiCoO2)

The high specific energy of lithium cobalt oxide makes it a popular choice for mobile phones, notebooks and digital cameras. The battery consists of a cobalt oxide cathode and a graphite carbon anode. The cathode has a layered structure in which lithium ions move from the anode to the cathode during discharge, and the charging process flows in the opposite direction.

2.Lithium manganate (LiMn2O4)

The capacity of lithium manganate is about one-third lower than that of lithium cobaltate. Design flexibility allows engineers to choose to maximize battery life or increase maximum load current (specific power) or capacity (specific energy)

3.lithium nickel cobalt manganese oxide (LiNiMnCoO2 or NMC)

 The secret of NMC lies in the combination of nickel and manganese. Similarly to this is the salt, in which the main components sodium and chloride are themselves toxic, but they are mixed as a seasoning salt and a food preservative. Nickel is known for its high specific energy, but its stability is poor; the manganese spinel structure can achieve low internal resistance but low specific energy. The two active metals have complementary advantages.

4.lithium cobalt aluminum aluminate (LiNiCoAlO2 or NCA)

It has a higher specific energy, and a fairly good specific power and long service life are similar to NMC. Less than flattering is security and cost. NCA is a further development of lithium nickel oxide; the addition of aluminum gives the battery better chemical stability.

5.lithium iron phosphate (LiFePO4)

Lithium phosphate has good electrochemical properties and low electrical resistance. This is achieved by a nanoscale phosphate cathode material. The main advantages are high current rating and long cycle life; good thermal stability, enhanced safety and tolerance for abuse.

6.lithium titanate (Li4Ti5O12)

LTO (usually Li4Ti5 O12) has zero strain, no SEI film formation and no lithium plating during fast charging and low temperature charging, thus having better charge and discharge performance than conventional cobalt blended Li-ion and graphite anodes. The thermal stability at high temperatures is also better than other lithium ion systems; however, batteries are expensive. The specific energy is low, only 65Wh/kg, which is equivalent to NiCd. Lithium titanate was charged to 2.80 V and at the end of the discharge was 1.80 V.
