What is a new generation of lithium battery research and development bottleneck?

Source: 2020 - 04 - 06 and clicks: time for a new generation of lithium battery research and development bottleneck at present, the electric car market penetration is higher and higher, the greater the energy density of battery, the longer the implementation range is, this is the electric car manufacturers spend a lot of energy to study. But how to solve the problem of energy density of power battery, many people focus on battery materials technology breakthrough. Government and industry has been set for the next generation of batteries 300 watts per kilogram of the target, they hope to achieve this goal in around 2020. At present, the international research field of lithium battery materials mainly concentrated in the lithium battery and lithium air ( Lithium oxygen) The battery. Two current electric car development bottlenecks, the mileage is not ideal, 2 it is charging, inadequate infrastructure, directly restricts the large-scale promotion of electric vehicles. In order to effectively improve the range of electric vehicles, the main battery manufacturers united auto manufacturers focus on lithium battery research and development of high performance, for example, Beijing new energy with South Korea SK opened the ternary lithium battery, battery empty volume of 30. 4 KWH, thank you, under the Beijing new electric car EV200 and EV210 range of vehicles more than 240 kilometers. However, some in the industry also believe that the electric car is not necessarily emphasizes the scope of the scope of the user should be according to their own needs to choose the appropriate model, after all, the scope of the range determines the cost of lithium-ion batteries, also does not favor the low-end market promotion and growing of electric cars. China's lithium ion battery may usher in a booming market momentum lithium-ion battery industry is expected to usher in the next few years the development of new energy vehicles, next year may last for this year's growth, for 2 - Three times the growth rate, optimistic estimates that the new energy automobile production next year will be 150 - 200000 units. Affected by this, as the new energy vehicles is the most important power battery lithium ion battery market may usher in a new round of turbulent momentum. Lithium ion battery industry research meetings held a few days ago, some related businesses, told reporters that with the expansion of the market, the current lithium battery market order has been very much, everybody is busy as a bee. Factors restricting the development of new energy vehicles include battery capacity. For example, caused by a lack of capacity, byd has delayed their production and sales order delivery of the battery. At the same time, the lithium ion battery industry norms and access policy is also the important changes. Ministry of Industry and Information Technology has issued a draft specification, lithium ion battery industry is put forward for lithium ion battery production implement conditional access policy. In the next few years, lithium battery industry merger and reorganization will continue to appear. At this point, if you are interested in lithium ion battery industry chain, investment, you can refer to the following three aspects: first, to invest now has strong profitability and growth is relatively stable lithium products deep processing field, such as lithium, butyl lithium metal and lithium chloride catalyst, new materials and the biomedical sciences. The second is the diaphragm, six fluoride phosphate lithium-ion battery industry chain technology development bottleneck, investment value. Third, if the lithium battery industry began to exceed expectations, so the positive material, negative material and electrolyte in areas such as leading enterprises will benefit a lot. You can also take a look at these companies.
