Power battery will usher in a reshuffle cost and performance face market test
With the rapid growth of production and sales of new energy vehicles in recent years, the gap in automobile battery production has gradually emerged. This has stimulated the enthusiasm of supporting battery enterprises. According to the latest data released by the China Association of Automobile Manufacturers, China's production of new energy vehicles reached 76000 in the first six months of this year, an increase of 2.5 times over the same period last year. However, while the output of new energy vehicles is growing rapidly, there is a gap in the output of supporting power batteries. Now the power battery basically as long as it can be made, the problem of selling out is not big. In fact, according to experts, the technical threshold for the production of new energy vehicle batteries is not high, which directly leads to the rapid expansion of power battery production capacity. However, the production of large quantities of low-tech battery companies may shift domestic battery capacity from shortage to surplus. Industry insiders expect that with the rapid realization of production capacity, the battery industry may usher in a reshuffle in the second half of 2016.

Development Plan for Energy-saving and New Energy Vehicles (2011-2020)
The world's nickel-metal hydride batteries are mainly produced by Chinese and Japanese companies, accounting for more than 95% of global production. The main markets for NiMH batteries are HEV and consumer battery products. Hybrid batteries will become the commanding heights of all parties. "Energy-saving and New Energy Vehicle Development Plan (2011-2020)", the main task before 2015 is to promote the use of hybrid vehicles and improve the fuel economy of traditional vehicles, and then promote domestic pure electric vehicles. The policy is clear. The world's nickel-metal hydride batteries are mainly produced by Chinese and Japanese companies, accounting for more than 95% of global production. More than 70% of the world's nickel-hydrogen batteries are produced in China. China's nickel-hydrogen battery enterprises mainly include Chaoba, Haopeng, BYD, Huanyu, Keliyuan, Likexing, Sanpu, Disheng, Sanjie, Quantitative Energy, Greep, etc. Japanese companies Panasonic, Yuasa and Sanyo have moved production of small nickel-metal hydride batteries to China.

The 10 most promising new materials for lithium batteries in the future
Silicon carbon composite material as a future negative electrode material, its theoretical gram capacity of about 4200 mAh/g or more, more than 10 times higher than the graphite negative electrode 372 mAh/g, its industrialization, will greatly enhance the capacity of the battery. Now the main problems of silicon carbon composite materials are: During charging and discharging, the volume expansion can reach 300%, which will cause the silicon material particles to powder, resulting in the loss of material capacity. At the same time, the liquid absorption capacity is poor. Poor cycle life. At present, the above problems are solved by means of silicon powder nanocrystallization, silicon carbon coating and doping, and some enterprises have made some progress.

What are the conservation practices of graphite crucible?
In the use of graphite crucible, often encounter some heater damage phenomenon, the device damage may be man-made or deterioration and other reasons, if it is man-made need to strengthen management, strengthen the staff's awareness of prevention, in the use of graphite crucible need to be handled gently, sometimes graphite crucible surface damage, this may be due to the impact during handling or the lack of moisture-proof treatment in the storage environment or the environment is not dry.

Graphite mold processing has a wide range of applications in the semiconductor industry
Graphite mold processing is widely used in the semiconductor industry. They are mainly used in the manufacture of integrated circuit chips and semiconductor devices, such as diodes, transistors and solar cells. First, graphite mold processing is used in the semiconductor industry to manufacture silicon wafers, which are the basic material for integrated circuit manufacturing. The graphite mold converts silicon raw materials into silicon wafers through high temperature and high pressure chemical reaction deposition technology, and then gradually forms integrated circuit chips through etching, etching, ion implantation and other process steps.

Reasons and solutions for soft spots on the appearance of graphite molds
Graphite mold presentation, immediately won the love of many customers, but there are customers reflect, graphite mold appearance soft point, this what reason? Graphite mold heat treatment after the appearance of soft point will affect the wear resistance of graphite mold, reduce the use of graphite mold life. Next, our company will introduce to you the reasons and solutions for the soft appearance of graphite molds. Graphite mold heat treatment should be removed before the scale, rust, in the quenching heating properly maintain graphite mold appearance, should try to use vacuum furnace, salt bath furnace and maintenance atmosphere furnace heating.
