In fact, in recent years, the battery main power comes from the industry's rapid expansion power battery demand of the industry, so the battery technology development, technology in the process of practical application is often the most need to consider is the need of power battery, and at this point, the lithium battery empty even at low magnification are great polarization will inevitably lead to very not ideal energy efficiency and the ratio of performance, this also is in the field of power battery for practical important obstacle to overcomeLithium-air battery is a very potential high capacity battery technology, the use of lithium metal and oxygen reversible reaction, the theoretical upper limit of the energy density of 11000 Wh/kg, far more than the pool is the actual energy density of 200 + Wh/kg, that result in the academia and industry, is widely considered to be a battery in the field of reverse technology in the future.

In 2017 China's new energy car policy adjustment, subsidies strength decline, the adding to fill the highest year-on-year decline more than 60%;With subsidies threshold is improved obviously, subsidiesPower batteryEnergy density, range, oil-saving rate, 30000 km mileage indicators such as direct link;Subsidy way also changed, from appropriations system, clearing systemUnder the policy adjustment, subsidies TuiPo and optimizing threshold increased pressure on the electric car industry chain enterprises.

China energy storage net news: recently, in wuhan university of technology institute of electrical and mechanical engineering professor Hu Ye hair team to cast new energy vehicle technology - "for new energy automobile generators and high density flywheel energy storage system", obtain 500 million yuan of investment in science and technology achievements transformationLearned, invented the technology for the world, such as to achieve mass production on the market, the size of the market is expected to create 5 billion yuan.

In 2017, 590900 tons of graphite electrode production in China, up 1571% from a year earlier.

The lithium battery main anode materials are tin base material, lithium base material, lithium titanate, carbon nanotube and graphene materials lithium battery energy density of the cathode material is one of the main factors influencing the lithium battery energy density, lithium battery cathode materials, anode materials, electrolytes, the diaphragm is known as the four core material of lithium-ion batteries.

With the release of the new subsidy regulations in 2018, reducing costs and increasing energy density have become the focus of power battery companies However, in the actual application process, the conventional method is difficult to ensure the ideal cycle life while improving the energy density, and there is also the risk of thermal runaway.

Diodes Incorporated's new AP9234L integrated circuit offers a wide range of protection features designed to provide a high-precision single-chip solution for single -cell Li-Ion battery packs and Li-Polymer rechargeable battery packs The new products are aimed at manufacturers of battery protection circuit modules for smart phones, cameras and consumer electronics of the same type.

Yesterday, the organizer of the "2018 Third Asia-Pacific Battery Show" to be held in Guangzhou in August was informed that China's lithium battery market share exceeded 60% in the global market, completely surpassing Japan and South Korea and winning the world first According to the organizers, the Asia-Pacific Battery Show has attracted more than 800 exhibitors from more than 50 countries around the world.

The pursuit of zero carbon trucks in the world's advanced countries is getting hotter and hotter, and the demand for new energy vehicle specifications has become increasingly clear However, the sluggish development of lithium battery technology today has clamped down on the cruising range and safety, making the upgrade of new energy vehicles slow.

Recently, Chinese scientists have led the world, and for the first time obtained atomic-scale resolution images of hydrated sodium ions, and discovered a magic number effect of hydrated ion transport This research opens a new door for the research of hot topics such as ion battery research and development, seawater desalination and biological ion channels.
