What are the challenges facing the current lithium battery?

Source: 2020 - 04 - 10 therefore hits: although lithium battery challenges, but its advantage is still obvious while in the field of future energy storage, lithium battery still need to face the liquid flow cell ( Represented by vanadium battery) , sodium sulfur batteries, such as the fierce competition, even in these technology industrialization is in the lead of Japan, also obviously tend to use lithium battery. The main reasons are: ( 1) Lithium battery can be applied to the more links, power generation and power consumption can be used; ( 2) Lithium battery energy storage system but can small, power grid companies and households can be used; More importantly, lithium battery can be effectively connect electric vehicle and smart grid. For the development of lithium battery line, generally speaking, competition or manganese acid lithium and lithium iron phosphate. In recent years, lithium manganese acid in mainland China has been more and more attention. The relevant administrative department of the Chinese government's attitude is not clear, but if you look carefully, you will find there are some differences between them. From the point of the attitude of the state-owned assets supervision and administration, it should support for lithium iron phosphate is one-sided. A central enterprise under the administration of the new electric car alliance members minmetals made it clear that to develop the lithium iron phosphate and related resources and raw materials industry. Miao wei, director of the Ministry of Industry and Information Technology used to be head of dongfeng motor, and has always been a close relationship with the Japanese enterprise, under his leadership, in choosing a car power battery, the Ministry of Industry and Information Technology tends to the possibility of lithium manganate. Science and technology minister Wan Gangzeng made fuel cell research, he may prejudice against the development direction of lithium batteries don't have much. Like 'for money to run, Ministry of Science and Technology should prefer those who have more pr experience in this field.
