What is the voltage of lithium manganate and lithium iron phosphate charging and discharging platform？

lithium iron phosphate batteries: with the whole battery discharge voltage of 3.2 V.Excellent high temperature resistance, high temperature performance is the best of the anode material.For the most part lithium electricity enterprises in China are now doing the lithium iron phosphate batteries, preparation process, performance ratio can also be, tap density is low.Invention patent in the United States, so may be in the future because of patent problem...

Manganese acid lithium battery: abundant manganese element, manganese acid lithium, cheaper rate performance is good, high temperature prone to manganese dissolved in the electrolyte by cladding processing can be improved.Capacity is low, high discharge voltage, higher than the commonly used cobalt acid lithium 3.7 V.Preparation technology mature, not pure in the patent problem.Japan and South Korea mainly for lithium manganese acid.China's typical representative unita solid, manganese acid lithium battery.

Monomer manganese acid lithium battery is 3.7 V, maximum charge voltage of 4.3 V, the minimum discharge voltage is 2 V

Standard single lithium iron phosphate battery is 3.2 V, maximum charge voltage of 3.65 V, the minimum discharge voltage is 2 V

(') containing Battery electrolyte solution and the cup of the metal electrode to generate an electric current, groove or other containers or composite part of the space, can convert chemical energy into electrical energy device.With the positive and negative.With the progress of science and technology, the battery refers to a small device can generate electricity.

1. Manganese acid lithium battery energy density than lithium iron phosphate batteries, ie, the same capacity of battery manganese acid lithium battery can do smaller size.

2. The cycle life of manganese acid lithium battery as the lithium iron phosphate batteries, generally in the 300-500 times, lithium iron phosphate battery can do 1800-2000.Namely the same specifications of the lithium iron phosphate battery capacity is the life of a manganese acid lithium battery life of 4-5 times.

3. The security of the manganese acid lithium battery as the lithium iron phosphate batteries.

4. The monomer of manganese acid lithium battery capacity biggest can do 10 ah, now can do 300 ah lithium iron phosphate.

5. The use of manganese acid lithium battery temperature environment range than the range of lithium iron phosphate batteries.

According to statistics, in 2015, the lithium iron phosphate battery of new energy vehiclesPower battery total amount of form a complete set of lithium iron phosphate batteries accounted for 69%,The ternary battery accounted for 27%, other system accounts for about 4%.About the "three yuan, lithium iron phosphate, manganese acid lithium battery on who is the mainstream technology in the future?"Has been debated.

Was held recently, the ministry of industry and information technology application about the planning of new energy vehicles safety supervision work stable cross will, on January 1, 2017, a new application for the catalog of new energy automobile application recommended models using ternary cell bus, need to fill the third party test report."Suspension lifted in January this year ternary lithium battery passenger car in a new energy automobile application recommended models catalogue "."Three yuan ban storm", but also push the "three yuan battery" position to high, triggered a new wave of power battery technology.

The second half of 2016, in fact, many companies have started three yuan battery project layout, such as the state's group invested 1.226 billion yuan, annual output of 35000 tons of ternary precursor project;Expansion has wisdom energy capital of 3.114 billion yuan, foster high-end ternary lithium electricity production line;Hengdian east magnetic spent 3 billion layout ternary lithium batteries;Green beauty to buy three yuan precursor production line, teamed up with state general layout ternary lithium batteries;The porch high-tech power ternary lithium battery.

Data analyst wang forward prediction after lithium radio and TV university, recently released by the conditions of automobile power battery industry norms "(2017) the opinions of the draft and network transmission of the 2017 new energy vehicles subsidies to adjust plan, etc. The influence of the policy, the ternary battery will usher in explosive growth.

In the future, manganese acid lithium, lithium iron phosphate three yuan will be three cent world?

On the one hand, due to "ban on three yuan" message has not yet been confirmed, on the other hand because of the ternary lithium battery electric bus safety also sceptical, therefore, battery manufacturers continue to stick to the lithium iron phosphate, lithium manganese acid strategic layout, the do three yuan technical reserves, the future for a long time, manganese acid lithium, lithium iron phosphate ternary will co-exist for a long time.In sponsored by the lithium rtvu data "2016 apec lithium electricity new energy leaders summit", to share the guest about "power battery technology route of" point of view and a view on this topic.The following is the summit guests some wonderful view:

Citic countries groupama Clarke dean Liu Zhengyao: lithium manganese acid and three yuan belong to a system, three yuan, to some extent can be said to be the upgrade of manganese acid lithium, there is no contradiction between, at present, the company has started the layout in the field of three yuan.

Hin high-tech countries hin high-tech dean Xin-feng li: three yuan production line has been put into production, the headquarters of Hefei ternary capacity of 2 GWH, while Qingdao the porch all is the production of three yuan.

Star of constant power supply technical director Cheng Kai: lithium manganese acid due to its own defects, star hengtong will three yuan and become a manganese acid lithium manganese acid lithium production.Company since August, September, in terms of ternary layout, of course, star will not give up manganese acid lithium, only will follow three yuan.

Walter, director of the institute batteries Xu Hui: different areas on the performance requirements of different batteries, battery application domain must be different.At present, the company existing reserves in terms of three yuan, but will give priority to the lithium iron phosphate.

Previously, BYD, said the company is currently listed all the models are using lithium iron phosphate batteries, but the company has also been three yuan battery research and development and technical reserves, is expected to be listed on the next new passenger car batteries used in the three yuan.According to the company is now in Huizhou, Kengzi, two power battery production base, at present a total of 10 GWH capacity, at the same time the company is currently Kengzi base of 6 GWH capacity expansion, is expected in the next year reaches producing.
