How many years can a ternary lithium battery use for?

Because constitute the electrolyte materials for lithium-ion batteries is different, lithium-ion battery is divided into ternary lithium battery and liquid lithium-ion battery. Ternary lithium-ion battery and liquid lithium-ion battery have the same anode materials, similar working principle, but different electrolyte. Ternary lithium battery has light weight, advanced energy storage capability, good discharge performance and can be made into a variety of shapes, and has a longer life span. Compared to the liquid electrolyte of lithium-ion battery, ternary lithium battery electrolyte is solid electrolyte, and can be made into a variety of shapes to improve specific capacity of the battery.

Amid rising global pollution, energy conservation and environmental protection has become the top priority of social development, at present our country energetically advocate environmental protection, and introduced some relevant policies, therefore, the environmental protection equipment more and more of the market. Including decreasing gasoline vehicles, new energy automobile market, small to charging treasure, etc, are all environmental protection batteries. Lithium batteries, lithium batteries, than a traditional lead-acid point to have short charging time, long cycle life, energy conservation and environmental protection no pollution, light weight, long life and other characteristics. Said it long service life, long to where?

International standard, the battery life does not come in through the time to say, but by cycles, namely complete after computing time, general lithium battery is between 300-500. A product of up to 800 yuan of battery. So choose a good battery supplier quality is guaranteed, longer service life.

The ternary lithium battery life is how long _ ternary lithium battery life problem resolution

If use lithium ion battery in high temperature environment, such as the temperature of above 350 c, storage battery power will continue to decrease, which makes the service life of the battery will not as long as in normal temperature environment in the work time. In under the environment of high temperature to recharge the battery, the battery will be subject to a greater degree of damage, thus influence the service life of batteries. Even in a hot environment will cause varying degrees of damage to the battery charging, so you should try to avoid in high temperature environment to recharge the battery. If to recharge the battery in low temperature environment, such as lower than 40 c environment, also can cause damage to battery.

If not for a long time for the ternary lithium ion battery, will reduce its life. Ternary lithium ion battery needs under the conditions of electronic long-term flow will reach its ideal life. The ternary lithium ion battery in the global commercial production technology is not very mature, now held by market share is not high.

Ternary lithium batteries, the theory of life about 800 cycles in the commercialization of rechargeable lithium batteries belong to medium. lithium iron phosphate is about 2000 times, and lithium titanate reportedly can reach 10000 cycles. The current mainstream of battery manufacturers in the production of three yuan batteries specifications promised more than 500 times in the book (under the condition of standard charge and discharge), but the batteries in group with battery pack after due to the consistency problem, mainly is the voltage and internal resistance can't be exactly the same, the cycle life of about 400 times. Manufacturers recommend using SOC window is 10% ~ 90%, it is not recommended for deep cycles, or you will to cause irreversible damage to the battery is the cathode structure, if can be calculated by shallow shallow filling, cycle life of at least 1000 times. In addition, the lithium battery if often to devolve electricity at high rate and high temperature environment, the battery life can break down to less than 200 times.

In nature, lithium is the lightest, the smallest metal atomic mass, its atomic weight of 6.94 g/mol, rho = 0.53 g/cm3.Lithium chemistry and lively, easy to lose electrons are oxidation of Li +, so the most negative standard electrode potential, is 3.045 V, electrochemical equivalent minimum, 0.26 g/Ah, these characteristics of lithium determines it is a very high specific energy of materials. Ternary lithium battery refers to the three transition metal nickel cobalt manganese oxide as the anode material of lithium secondary battery. It fully integrated the nickel cobalt acid lithium good cycle performance, high capacity of acid lithium and lithium manganese acid of high security and low cost etc., using molecular hybrid, doping, coating and surface modification methods such as synthesis of nickel cobalt manganese compound lithium oxide embedded multi element synergy. Is now widely research and application of a lithium ion rechargeable battery.

The ternary lithium battery life

Lithium battery life refers to the battery in use after a period of time, capacity attenuation for the nominal capacity (room temperature 25 ℃, standard atmospheric pressure, and in the battery capacity of 0.2 C discharge) of 70%, can think life is terminated. In the industry generally to lithium battery full cycle times to calculate the cycle of life. In the process of using, lithium battery irreversible electrochemical reactions can occur within the led to the decrease of the capacity, such as the electrolyte decomposition, the inactivation of active material, is the collapse of the cathode structure embedded in lithium ion and reduce the number of embedded off and so on. Experiments indicate that leads to a higher ratio of discharge capacity attenuation, faster if the discharge current is low, the battery voltage will close to balance, can release more energy.

At present, the market price of the ternary lithium ion battery is higher than the density of its liquid lithium ion battery, relative to the liquid lithium ion battery, its long life, safety performance is good, believe in the near future there will be a big rise in space.

According to the technical level of the ternary lithium batteries, if used properly, the electric cars can use more than 5 years at least. If use undeserved, 2-3 years of lithium battery life is attenuation was finished.

The so-called used properly or not, basically be to see whether can abide by the principle of shallow filling, do not overuse.

Brief introduction:

The ternary polymer lithium battery is correct material using lithium nickel manganese cobalt ternary cathode material of lithium batteries, lithium ion battery cathode material has a lot of kinds, and mainly include cobalt acid lithium, lithium manganese acid lithium, nickel, ternary material, lithium iron phosphate, etc. The batteries of the ternary materials instead of the previous widespread usage of cobalt acid lithium batteries are widely used in the field of laptop batteries.

The ternary polymer lithium battery performance:

In a relatively balanced capacity and safety of materials, good cycle performance in normal cobalt acid lithium, early due to technical reasons the nominal voltage is only 3.5 3.6 V, limited in scope, but so far, as incremental improvements were made in the formulation and perfect structure, nominal voltage of battery is 3.7 V, on the capacity has reached or exceeded cobalt acid lithium battery level.

The ternary polymer lithium battery status:

The five largest batteries brand SANYO, PANASONIC, SONY, LG, SAMSUNG have launched ternary material of batteries. A considerable part of the laptop battery line with ternary material batteries is replaced by the previous cobalt acid lithium batteries. SANYO, SAMSUNG pillar battery has halted cobalt acid lithium battery to ternary battery manufacturing. At present, power battery with small size and high ratio at home and abroad tends to use ternary cathode materials.
