The best of all worlds.....

 

Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2) in short NMC, is the most versatile lithium chemistry. It combines good safety with good lifetime. Moreover, by playing with the mix of nickel and manganese, the result can be a cell with high power or with high energy.

In avionics application the current and power are small compared to batteries for e-bikes or handtools. Thus the goal is to get the maximum energy. A Korean manufacturer of NMC-cells, LG, produces a cell with 12-13Wh per cell. Moreover the variation between cells is very small. If these cells are combined to a battery with a high-quality BMS, the normal cycle life of 500-800 is raised to above 1500 cycles. Which nearly equals the longevity of LFP (2000 cycles).

The result is the 12V NMC battery of 20Ah in a standard housing. The battery has an energy content of 24*12= 288Wh, in a yellow case, so it is easily distinguished from other chemistries.

Compared to LFP (blue line) the new NMC battery has more than double the energy. And about four times the energy of lead-acid.
