''Lithium nickel cobalt aluminum oxide ('''LiNiCoAlO2''' or '''NCA''') and lithium titanate ('''Li4Ti5O12''' or '''LTO''') are specialty designs aimed at particular niche roles.''
''The new '''lithium sulphur''' batteries promise the highest performance to weight ratio.''
http://batteryuniversity.com/learn/article/types_of_lithium_ion
''While Li-aluminum (NCA) is the clear winner by storing more capacity than other systems, this only applies to specific energy.''
''In terms of specific power and thermal stability, Li-manganese (LMO) and Li-phosphate (LFP) are superior.''
''Li-titanate (LTO) may have low capacity but this chemistry outlives most other batteries in terms of life span and also has the best cold temperature performance.''

== [https:''high current rating and long cycle life, besides good thermal stability, enhanced safety and tolerance if abused.'' ''LiFePO4 is more tolerant to full charge conditions and is less stressed than other lithium-ion systems if kept at high voltage for a prolonged time. As a trade-off, the lower voltage of 3.2 V/cell reduces the specific energy to less than that of LMO. With most batteries, cold temperature reduces performance and elevated storage temperature shortens the service life, and LiFePO4 is no exception. LiFePO4 has a higher self-discharge than other Li-ion batteries, which can cause balancing issues with aging.'' ''Four cells in series produce 12.8 V, a similar voltage to six 2 V lead acid cells in series. Vehicles charge lead acid to 14.4 V (2.4 V/encell) and maintain a topping charge.wikipediaWith four LiFePO4 cells in series, each cell tops at 3.org6 V, which is the correct full-charge voltage. At this point, the charge should be disconnected but the topping charge continues while driving. LiFePO4 is tolerant to some overcharge; however, keeping the voltage at 14.4 V for a prolonged time, as most vehicles do on a long drive, could stress LiFePO4. Cold temperature operation starting could also be an issue with LiFePO4 as a starter battery.''

''high thermal stability and enhanced safetySimilar to LMO, but these systems can be tailored to serve as Energy Cells or Power Cells. For example, NMC in an 18650 cell for moderate load condition has a capacity of about 2800 mAh and can deliver 4 A to 5 A; NMC in the cycle same cell optimized for specific power has a capacity of only about 2000 mWh but delivers a continuous discharge current of 20 A. A silicon-based anode will go to 4000 mAh and calendar higher but at reduced loading capability and shorter cycle life are limited. Silicon added to graphite has the drawback that the anode grows and shrinks with charge and discharge, making the cell mechanically unstable.''
''Low internal cell resistance enables fast charging and highNMC is the battery of choice for power tools, e-current dischargingbikes and other electric powertrains. In an 18650 packageThe cathode combination is typically one-third nickel, Lione-third manganese can be discharged at currents of 20–30A with moderate heat buildup. It is also possible to apply and one-second load pulses of up to 50Athird cobalt, also known as 1-1-1. A continuous high load at this current would cause heat buildup and This offers a unique blend that also lowers the cell temperature cannot exceed 80°Craw material cost due to reduced cobalt content. Li-manganese Another successful combination is used for power toolsNMC with 5 parts nickel, medical instruments, as well as hybrid 3 parts cobalt and electric vehicles2 parts manganese.Further combinations using various amounts of cathode materials are possible. New electrolytes and additives enable charging to 4.4 V/cell and higher to boost capacity''
''Design flexibility allows engineers to maximize the battery for either optimal longevity (life span), maximum load current (specific power) or high capacity (NMC has good overall performance and excels on specific energy). For example, This battery is the long-life version in preferred candidate for the 18650 cell electric vehicle and has a moderate capacity of only 1,100mAh; the highlowest self-capacity version is 1,500mAhheating rate.''
''Most There is a move towards NMC-blended Li-manganese batteries blend with lithium ion as the system can be built economically and it achieves a good performance. The three active materials of nickel , manganese and cobalt oxide (NMC) can easily be blended to improve the specific suit a wide range of applications for automotive and energy and prolong the life span. This combination brings out the best in each system, and the LMO storage systems (NMCEES) is chosen for most electric vehicles, such as the Nissan Leaf, Chevy Volt and BMW i3that need frequent cycling. The LMO part of the battery, which can be about 30 percent, provides high current boost on acceleration; the NMC part gives the long driving rangefamily is growing in its diversity.''
