"Lithium battery + lithium primary battery" dual main business went hand in hand, Yiwei lithium handed over a brilliant results in 2017 On March 20, Yiwei Lithium released its 2017 annual report.

From February 28th to March 2nd, 2018, the 9th Japan International Secondary Battery Exhibition (BatterJapan2018) was held at the Amimoto International Exhibition Center in Tokyo, Japan As one of the largest battery exhibitions in the world, the exhibition brought together secondary batteries, capacitors, various related high-end technologies, materials, components and advanced devices for the production of secondary batteries and capacitors, attracting a large number of global secondary battery production.

The C290-30 fuel cell module independently developed by Shanghai Shenli Technology Co, Ltd.

Power battery Scale moved nearly retired time limit On May 17th, the ministry issued the new energy automobile power storage The battery Recycling traceability management interim provisions (draft), to further standardize power battery the whole process of information collection, the main body of each link to recycle responsibility regulatory requirements are put forward.

Lithium iron phosphate batteries The long life, cycle life over 2000 times Under the same conditions, the lithium iron phosphate batteries can use seven to eight years.

The recent Beijing XieDao NK 800 electric cars on fire explosion will once again power battery security of the pushed to the forefront, the lithium battery security become lithium battery to the bottleneck of energetic materials, large-scale development, under normal circumstances, the abuse test internal short circuit occurs in the biggest risk, the battery temperature rise sharply, and may eventually lead to thermal runaway, therefore in the laboratory on the risk of internal short circuit and improve the method of the research is valuablePower battery standardization technology committee of Guangdong province is Guangdong province pledges inspect bureau under the leadership of the organization for standardization, the new energy automotive power battery standard of acupuncture at home and abroad were studied.

Silicon is given the highest known lithium ion anode materials, can achieve 4200 mah/g, are supposed to be Lithium ion batteries The first choice for anode materials, is widely used but why not? This is due to its limitation crystal structureThe structure of silicon and graphite layers is different (pictured), the energy storage mechanism is similar to metal materials by alloying and alloying with lithium ion, the charge and discharge electrode reaction can write down the type:Si + xLi++ xe - > LiXSiElemental silicon as the cathode material is The battery Charge and discharge principle as shown in the figure below:Can be read by the figure in the part of rechargeable lithium ion from the anode material emerge between embedded inside the silicon crystal lattice, caused great expansion (about 300%), to form silicon lithium alloy.

ChemafSarl Cobalt company, as a new and unknown small companies, is now in the accelerating cobalt ore mining, production capacity in the future or will catch up with glencore energy companiesHeadquarters is located in Lubumbashi ChemafSarl mining company is using the surge in demand of cobalt and other several companies, small copper miner Congo to move into a cobalt producer, to preempt the refiners and new energy automobile manufacturers supply market.

The LME metals seminar Asia held in Hong Kong, vice President of huayou cobalt industry Frank Chen said huayou cobalt industry plan will yield increased by 50% in 2018, the increased from the original annual production capacity of 20000 tons to 30000 tons, to increase the supply of the electric car market The company has also established the supply chain management of mining in Africa.

Own battery technology to control the high development and production costs of key components It comes as the world's second-largest truckmaker tries to ramp up research and development and production of electric trucks.
