Which lithium cell chemistry for mobile and wearable devices is good for high energy, small size and weight, at 50 to 100mAh:
Occasionally short pulse (2 seconds or less) discharge at 1C.
Routine discharge 15mA for ms, once per hundreds of seconds
Weeks to a few months per recharge.
No need for fast recharge time.
Price point is medium to high consumer electronics (seem price is not high for this small mAh).
Searching shows that there are four major types:
Lithium Cobalt Oxide(LiCoO2) — LCO
Lithium ion manganese oxide battery (LMO)
Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM
Lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate)
Many thanks
