On the 9th, in the Straits Optoelectronics Industrial Park of the Liancheng County Industrial Park, the Fujianguo Guanguan New Energy Lithium Battery Project was completed and put into operation The project is a key optoelectronic new material industry project introduced by Liancheng last year.

After the high performance of 2017, this year's photovoltaic companies continue to maintain a good performance In the first quarter, 26 companies listed in the photovoltaic industry had a net profit of over $100 million, and 17 had a net profit that doubled compared with the same period a year earlier, according to data from Eastern Fortune Chice.

The differences of energy storage equipment are mainly reflected in the design ability of battery management system (BMS) and product design ability Battery use is expected to increase significantly in the next few years, with the largest markets being North America, Europe and the asia-pacific region, the international renewable energy agency said in its "" RethinkingEnergy2017" "report.

Lead acid battery is an important part of the electric system of agricultural vehicles and tractors The life of the battery is closely related to the use and maintenance, and improper use and maintenance can cause early damage to the battery.

Have to admit, even if has slashed prices, the lithium battery in the face of the lead-acid battery, the price is still in its disadvantage, but focus on lithium battery products, consumer experience, the performance of comprehensive factors such as recycling, electric two rounds, tricycle with lithium batteries will be more cost-effective than lead-acid battery productsA lithium power plant business group we calculate the bill: common 4812 the market in the current electric two-wheelers, for example, in support of the same specification range of battery products, lithium-ion batteries for lead-acid batteries for 1.

At present, most of the mainstream vehicle GPS on the market uses a built-in lithium battery power supply method Lithium-ion batteries have stable discharge, small size and other characteristics compared to the traditional nickel-metal hydride, nickel-cadmium batteries are obvious advantages.

The reporter learned from the new energy and material chemistry laboratory of the institute ofspecial energy and new energy technology of tsinghua university that the problem of industrialized production of key materials and catalysts for fuel cells has been overcome by the joint research and development team of hydrogen fuel cell laboratory of tsinghua university and a technology company in wuhan At present, the catalyst has 17 patents, the production capacity of 1200 grams per day, and the price is only half of the imported products.

Silicon is given a known (4200 mAh/g) of the highest lithium ion batteries anode materials, but because of its huge volume effect (> 300%), silicon electrode materials in the process of charging and discharging will pulverization and peeling from the collection of fluid, make active substances and active substances, loss of electrical contact between the active materials, at the same time constantly forming new solid electrolyte layer SEI, eventually lead to the deterioration of the electrochemical properties In recent years, the researchers have done a lot of research and exploration, and try to solve these problems and achieved some results, this paper stated the research progress in the field, and further research direction and application prospect is put forward.

At present, the main international chemical energy storage technologies include sodium sulfur battery, lithium battery, liquid flow battery, lead-acid battery, lithium iron phosphate battery and so on Research fellow of dalian institute of chemical physics, Chinese academy of sciences said, with the development of renewable energy industry and electric vehicle industry, energy storage technology and industry are highly valued by all countries, and research and development of various new electrochemical energy storage battery technology has made continuous progress.

On the first day of April, it was thrust into the spotlight by an announcement from allergan, followed by several that plunged it into crisis and left its future in question"Thunder from the ground"On the afternoon of April 1, jianrehuaneng announced that: the company has been overdue debt situation; The company is 19 years overdue.
