In February this year, the United States UnitedTechnologyCorp. The latest generation of fixed fixed fixed-type fuel power battery Purecell-400 system has run 100,000 hours on the spot to achieve milestone achievements. Purecell-400 design system consists of air treatment unit, power supply unit, electrical control unit, thermal energy and water treatment unit, fuel process unit, cooling module, and remote monitoring. The fuel power lithium battery uses natural gas as the raw material, with a maximum output power of

The key to reducing energy storage costs is to solve problems such as safety and cycle life of energy storage batteries. The senior engineer of the Institute of Electric and New Materials of China Institute of Electricity Sciences came to Xiaokang to pointed out that the breakthrough of these technologies is the prerequisite for industrialization of energy storage, but the maturity of battery technology may take many years, and pessimistic may be more than ten years. Whether the lithium battery technology adopte

The coating process is divided into three sections, one is the slurry system, the other is the coating system, and the third is the polar dried system. The triple -in -one requires each system to maintain stability to ensure the consistency of the pole. This article will affect the consistency of lithium battery performance from the perspective of coating. The slurry system is transferred to the slurry tank after the mixing is completed, and the diaphragm pump is transferred to the transition cylinder, and the s

The colloid battery is also a type of lead -acid battery. The improvement of the ordinary lead -acid battery of liquid electrolytes is used to replace the electrolytes of sulfate with colloidal electrolytes, thereby improving safety, power storage capacity, discharge performance and service life. At present, colloid batteries are widely used in the fields of power generation, communication, automobiles, emergency lighting and other fields. Why is it so popular? Let ’s analyze the technical principles of the c

With the rapid development of electric vehicles, how to solve the safety problems brought by electric vehicles has become a new topic and difficulty in the automotive industry. As the power source (or one of the source sources) of electric vehicles, the power battery system has become the focus of public security and reliability. The failure mode of the research on the power battery system is of great significance to improve the battery life, the safety and reliability of electric vehicles, and reducing the cost of

To realize the average battery of each single battery of the series battery packs, there are currently several methods: 1. Add a parallel balance circuit to each single battery in the battery pack to achieve the role of diversion. In this mode, when a battery first reaches a full charge, the balanced device can prevent it from charging and converting excess energy into heat energy, and continue to charge the unfeeling battery. This method is simple, but it will bring energy loss and not suitable for the fast cha

With the popularization of new energy vehicles, we see more and more people driving pure electric vehicles in the city. The increase in the use of the population has also risen the demand for charging piles. Fast charging has become one of the core needs of many car owners for pure electric vehicles. However, in the actual use process, many car owners are also worried that the multi -frequency fast charging will speed up the loss of power lithium batteries and reduce their service life? So what is the real situatio

The strength of the polymer lithium ion battery 1. Good safety performance. The polymer lithium -ion battery is used in the structure of aluminum -plastic soft packaging, which is different from the metal shell of the liquid battery cell. Once a safety hazard occurs, the lithium -ion battery is simply blasting. 2. The thickness of the thickness can be thinner, ultra -thin, and the thickness can be less than 1mm. It can be assembled in a credit card. The thickness of ordinary liquid lithium -ion batteries has

Graphene is a graphite thin tablet composed of a layer of carbon atom. It is the most well -known material in conductive performance, which makes it great in the field of microelectronics. The theoretical research of graphene has a history of more than 60 years. In addition to the application of electronic devices, graphene has been widely used in the fields of battery electrode materials, hydrogen storage materials, nano -composite materials, and biosensions. Polyineine has the characteristics of chemical nature,
