LCO : Its applications are in electronices device to all laptops and phone batteries.
LMO : High temperature stability and safety relative to other Li-ion types as it has integrally high thermal stability thus needs less safety circuitry than cobalt system.High rate capability due to low internal cell resistance which benefits fast charging and high current discharging.Also used as secondary battery.
NCA : It has been around since 1999 for special applications. It shares similarities with NMC by offering high specific energy, reasonably good specific power and a long life span.
LPF :
- Very safe and secure technology
- Very low toxicity for environment
- Operational temperature range :up to 70°C
- Very low internal resistance. Stability or even decline over the cycles.
- Constant power throughout the discharge range
- Ease of recycling.
LTO :
- Excellent low temperature discharge characteristics
- Zero strain property, no formation of SEI film nor lithium plating when charging at low temperature or fast charging
- Long life time
- Fast charge capability and wide temperature range
- Among the safest types of Li-ion batteries

As obsering all specification of all battery if having look on the costly one is LCO,LMO,NMC and cheap one is LTO.
LFP & LTO are having high life span, NCA has less life span.
Best performance has LTO battery & specific power is high in LFP.
Looking on saftey LTO,LFP is highly safe while LCO & NCA is least safe.
LCO,LMO,NCA having high specific energy.
