What is the important performance of power lithium-ion battery?

The performance of lithium-ion power lithium-ion batteries mainly depends on the positive and negative materials. The use of lithium iron phosphate as a lithium battery material is only a matter of recent years. The development of large-capacity lithium iron phosphate batteries in China was in July 2005. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power lithium-ion batteries. 1C charge and discharge cycle life can reach 2000 times. Single-cell battery will not burn when overcharged at 30V, and will not explode after breakdown The lithium iron phosphate anode material makes the large-capacity lithium battery easy to use in series. Meet the requirements of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price and long service life. It is an ideal negative electrode material for a new generation of lithium batteries. This project belongs to the development of functional energy materials for high-tech projects, and is a key support area of u200bu200bthe national 863 plan, 973 plan and the 11th Five-Year High-tech Industry Development Plan. Lithium iron phosphate materials for lithium batteries have great advantages in terms of safety performance and cycle life, and are also one of the most important technical indicators of power lithium-ion batteries. 1C charge and discharge cycle life can reach 2000 times, breakdown does not explode, overcharge is not easy to burn and explode. Lithium iron phosphate cathode materials make large-capacity lithium batteries easier to use in series. Research and application recently reported that new batteries are expected to replace traditional lithium batteries, which brings hope to the battery life of mobile phones and tablets, but most of them are still in the laboratory research stage, and it is not clear when or if they will Large-scale commercial use. In August 2012, DebochTEC, a new energy company. German Electric Power Co., Ltd. (GmbH) has brought a new energy technology to reality: iron-containing lithium batteries. Detective Deboch. GmbH, according to the lithium iron phosphate battery technology, a white paper published on the use of composite nanomaterials, a single cell 32650 specification (32mm diameter/length is 65 mm) battery can increase 6000mah, energy density and the current industry’s 32650 specification single cell 5000mah, Compared with the new 1000mah of the same volume, it is as high as 20%. The first section can charge the iPhone4s mobile phone almost four times. Even better, in a single low-power charging and discharging environment, the battery can still maintain 80% of the power after 3000 cycles. In contrast, ordinary lithium batteries can only maintain about 500 times of power. According to the calculation of charging and discharging once every 3 days, it can be used continuously for 24 years, which is a true long-life battery. This new battery technology can be widely used in portable power supplies, small UPS, laptop batteries, car batteries and other equipment. DebochTEC also uses different battery colors according to different working environments. In the field of civilian automobiles, blue is used, 2500 times; the green 2000 version is suitable for small portable mobile devices.
