Advantage

Since early 2014, all aspects of lithium ternary material constantly modified, increasing the number of cycles, the current appropriate increase in the cost of already more than 1500 times, and the safety performance of lithium ternary material is constantly improving, more and more close to LifePo4 batteries. The past two years the emerging new nickel-cobalt-aluminum ternary materials, although in the battery manufacturing process on the environment are higher, but the stability and security further enhanced, as recognized by many battery factory, trial production.
cylindrical battery
High voltage platform. Voltage platform is an important indicator of the battery energy density, determines the basic performance and cost of the battery, so the choice of battery materials, has important significance. Voltage platform, the greater capacity than certainly the same size, weight, even when the battery pack is the same, a relatively high voltage platform mileage lithium ternary material farther. Ternary materials platform significantly higher voltage than LifePo4, high line can reach 4.2 volts, the discharge platform can reach 3.6 or 3.7 volts. 
  • High energy density
  • High tap density
Ternary lithium battery energy density, cycle performance better than normal lithium cobalt oxide. Now, with the continuous improvement and improve the structure of a recipe, the nominal battery voltage has reached 3.7V, the capacity has reached or exceeded the level of lithium cobalt oxide. These lithium is always used in solar powered portable generator

Disadvantages
  • Poor in security
  • High temperature difference
  • Low life cycle
  • High-power discharge difference
Toxic elements (after a sharp rise in the temperature of the charge and discharge ternary lithium battery-power, high-temperature release oxygen very easy to burn)

Power lithium ternary material mainly nickel and cobalt aluminum lithium battery, nickel, cobalt and manganese LEP batteries, due to high temperature nickel-cobalt-aluminum structure is unstable, resulting in poor high-temperature safety and high pH monomer flatulence easy to make, and then dangerous and the current high cost.
