What's the difference between ternary battery and lithium battery?

The so-called lithium iron phosphate batteries refer to the lithium iron phosphate used as the anode material of lithium ion batteries. Because the characteristics of this kind of battery that do not contain precious metal elements (such as cobalt, etc.), the cost of raw materials of lithium iron phosphate battery can be very cheap. In actual use, lithium iron phosphate battery has high temperature resistance, strong stability, low cost and good cycle performance.

The ternary lithium battery is refers to the use of nickel cobalt manganese acid lithium as the anode material, graphite as the cathode material of lithium battery. Unlike the lithium iron phosphate, ternary lithium battery voltage platform is very high, which means under the same volume or weight, ternary lithium battery than power, greater than power. In addition, in the big charge ratio, and low temperature resistance, etc., the ternary lithium battery also has a great advantage.

A, low temperature discharge performance is better

China's vast, climate is complex, from the three northeastern provinces in the north to the temperature changes at the southernmost tip of Hainan islands are abundant. In Beijing, for example, as the main electric car market, Beijing summer high temperature around 40 ℃, while winter is basic about 16 ℃ below zero, even lower. This temperature range is suitable for low temperature performance obviously better ternary lithium battery. And pay attention to high temperature resistant performance of lithium iron phosphate batteries in winter in Beijing would seem to be some lack of power.

"Relative capacity of 25 ℃" refers to the different temperature conditions to devolve electricity capacity and 25 ℃ when the ratio of discharge capacity. The numerical can accurately reflect the attenuation of battery under the condition of different temperature range, the more close to 100%, the better the cell performance.

Can see from the above, 25 ℃ as a benchmark in normal temperature, two types of cells in 55 ℃ high temperature lowering electricity and room temperature 25 ℃ to devolve electricity, almost no difference between the discharge capacity. But at 20 ℃ below zero, the ternary lithium battery and lithium iron phosphate battery has obvious advantages compared., 】

The ternary polymer lithium battery is correct material using nickel cobalt manganese acid lithium (Li (NiCoMn) O2) ternary positive electrode material of lithium battery, the ternary composite cathode material precursor products, is the cobalt nickel salt, salt, manganese salt as raw materials, in the proportion of nickel cobalt manganese can according to the actual need to adjust, the ternary material cell relative to the anode cobalt acid lithium batteries high safety, but the voltage is too low, use mobile phones (cell phones as general at around 3.0 V voltage) will feel the lack of obvious capacity.

Three yuan 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 are instead before the widespread use of cobalt acid lithium batteries, widely used in the field of laptop batteries.

Sustained current standard discharge: 0.2 C

Sustained current biggest discharge: 1 c

Protect parameters: the overcharge protection voltage/each string of 4.325 + / - 0.025 V

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 been reached or exceed cobalt acid lithium battery level.

The five largest batteries brand SANYO, PANASONIC, SONY, LG, SAMSUNG has launched three yuan material of batteries, a considerable part of the laptop battery line with ternary material of batteries to replace the previous cobalt acid lithium batteries, SANYO, SAMSUNG pillar has halted cobalt acid lithium batteries battery to three yuan batteries manufacturing, small high ratio of power battery at home and abroad most use ternary cathode material.

Refers to ternary, the inside of the lithium battery cathode material name the ternary material is nickel cobalt manganese acid lithium Li (NiCoMn) O?, ternary composite cathode material precursor products, is the cobalt nickel salt, salt, manganese salt as raw materials, in the proportion of nickel cobalt manganese can according to the actual need to adjust, 18650 refers to a cylindrical battery appearance size: 18 means the battery 18.0 mm650 refers to the cell height 65.0 mm in diameter, more for cellphones. Lithium battery is general, the battery on the market are mostly,

Refers to the ternary, the inside of the lithium battery is called cathode material. Regular cobalt acid lithium battery cathode material is LiCoO2, ternary material is nickel cobalt manganese acid lithium Li (NiCoMn) O2, ternary composite cathode material precursor products, is the cobalt nickel salt, salt, manganese salt as raw materials, in the proportion of nickel cobalt manganese can according to the actual need to adjust, the positive battery ternary material compared with cobalt acid lithium battery safety is high, but the platform is too low, with a mobile phone (mobile phone through general at around 3.4 V voltage) will feel the lack of obvious capacity.18650 refers to a cylindrical battery appearance size: 18 cell diameter of 18.0 mm650 cell height 65.0 mm more other anode materials used in addition to the three yuan, have cobalt acid lithium, manganese acid lithium, lithium iron phosphate, NCA, etc.

Lithium-ion batteries, refers to a very wide range of categories, those who use lithium materials can be called a lithium battery. The lithium battery in accordance with the scientific name, we say at ordinary times should call/lithium secondary battery, lithium ion batteries have corresponding anode materials.

Lithium ion battery anode materials mainly have cobalt acid lithium LiCoO2, LiMn2O4 manganese acid lithium, nickel acid lithium LiCoxNiyMnzO2, ternary material, lithium iron phosphate LiFePO4, etc.The positive use ternary material called ternary lithium batteries;

Ternary lithium battery main advantage is that the energy density is higher than other materials.

The ternary lithium battery cathode material is divided into NCA aluminum nickel and cobalt and sliding nickel cobalt manganese;

Most of the ternary material for sliding, usually we mentioned the ternary lithium battery is sliding. Sliding on behalf of the manufacturer abroad is SDI, SKI in China mainly lishen, hui tong world, Bick, universal, lang can wait. Tesla's NCA18650 type, NCA relatively strong stability, and cycle performance is strong; But in the process of production, due to Al for amphoteric metal, not precipitation, therefore process exists on the threshold. Due to the NCA chinalco's content is too little, so often referred to as the binary materials.

Ternary material sliding model from 111 ternary (N: C: M = :) to 433, 532, 622, 811. With nickel content increasing, the battery energy density and the corresponding upgrade for ten position.
