Battery comparison: Lithium-manganese oxide (LiMn2O4) and Lithium-nickel oxide (LiNiO2)
In the last blog we compared LFP and LCO batteries based on some basic specifications. Here in this blog, we will compare Lithium-manganese oxide (LMO) and Lithium-nickel oxide (LNO) batteries according to the same specifications.
We will again start with safety. As far as LMO battery is concerned, it is safer than the LNO battery. Under extreme conditions, LNO becomes unstable and is not easy to handle. Environmental safety of LMO battery is acceptable whereas LNO battery is quite dangerous to the environment. Now when you think of cycle life, then both the batteries give acceptable performance. If we go by power and weight density, then LNO batteries outrun LMO batteries. This is precisely the reason why LNO battery poses a threat to the environment.
Even though LMO battery has somewhat lesser power and weight density, they have low operating cost in the long run. On the other hand, LNO will cost you more. In other words, LMO is more economical than the LNO battery. But when the operating temperature rises beyond 50 degree Celsius, LMO battery starts decaying and that too at extreme rate. Even though LNO battery has some disadvantages associated with it, it will work smoothly in temperatures ranging between -20 to 55 degree Celsius!
