My question pertains to different types of the Li-ion batteries currently available.


Many of them address relevantl issues which are generally faced with the current type of Li-ion used in everyday electronics, probably the Li cobalt based battery.

Like Li-manganese based cells which are considered thermally stable than most other types or Li-NMC which in my opinion should become the battery type of choice to be used for everyday electronics, having better energy density, longer life and obviously safe. (It even has the same nominal voltage and cut-off power, can be replaced?)

Obviously, these may not be revolutionary in its ultimate objective, but it definitely is better than the current choice used, considering even that was used to replace the erstwhile Ni-Mh based batteries as, only, a better upgrade after all.

So technically speaking, why isn't Li-NMC, for eg, not being used in laptops or smartdevices, etc? Is there something else missing, in the engineering choice of it?

PS - Not referring to the cost or industry adoption rate, etc

  • \$\begingroup\$ That is true, but there is one more truth about cost - it decreases with rapid use. I can get LI-NMC for maybe 50% more than the usual ones, which is not much if you work in volumes. \$\endgroup\$ – arjun Jan 30 '16 at 11:11
  • \$\begingroup\$ Yes, but the decrease is on a FCFS basis. \$\endgroup\$ – Ignacio Vazquez-Abrams Jan 30 '16 at 11:12
  • \$\begingroup\$ That is true in a lot of scenarios. The main thing which I could not understand was if there are better alternatives, there should be a reason to use it. For Li-NMC, for eg, if I am using it in a project without even replacing the Li-baterry management ICs, it is obviously a benefit, in terms of end usage. Cost can be then overcomed gradually. Other than cost, is there any engg specific issue I should also look into. None I can find for NMC. For Titanate I can assume, yes, because the entire power system would have to be changed and it can be costly. Similar with others. \$\endgroup\$ – arjun Jan 30 '16 at 11:18

Besides (but related to) cost, you must consider availability. While you can buy a few of them easily enough, batteries of new technologies take time to reach mainstream usage because it takes time to get the production up to the millions/day demand level of mainstream use.
