At present, the phosphoric acid fuel cell (PAFC) fuel cells have become all the most practical one, it has a higher efficiency, the power generation system with good environmental performance, the market is expected to be further expanded. Phosphoric acid as the electrolyte because the operating temperature of 200 degrees, (more…)

In principle, the two electrodes in the electrolyte, as long as the potential difference can be formed cells, regardless of how the potential difference is formed. Formed by the molten salt electrolyte batteries, the battery electromotive force of the initial use of molten salt electrochemical system for the study of various (more…)

Usually heat the battery pack stack is another series of single cells, single heating film, heating film and the buffer chip clients such Components. When assembled into the stack assembly through the center rod ends tighten the nut or other methods to put pressure on the stack. Stack size of the pressure performance of the (more…)

(1) the possibility of introducing a large number of

On the power grid in the system power, the large scale of power generation efficiency, economy Gao, due to these advantages, atomic energy, fire, water, etc. account for most of the power supply. However, as represented by the carbon dioxide lead to global warming emissions of gas and hazardous substances system (more…)

As the overcharge and over discharge all affect the life of lithium-ion battery, so in general electronic components are to prevent over charge and over discharge of the device or electronic circuit, but in use should be possible to prevent over charge and over discharge. For example, mobile phone battery charging process, (more…)

Gel polymer electrolyte was first reported in 1975, using PAN and crosslinked copolymer VDF-HFP electrolyte salt with the PC and the preparation of physical cross-linking and chemical cross-linked gel. However, until after the birth of lithium ion batteries, gel polymer electrolytes was developed rapidly. (more…)

Carbon materials with graphite structure before, we must first go through a carbonization process, and then again in 2000 degrees for graphite.

carbonization process

Walker said: “Since the starting organic precursor by heat treatment to convert the former can be controlled with the arrangement of the carbon (more…)

Classical carbon materials was originally a very old material, its use can be traced back to BC, the large number of industrial production and applications as early as the mid 19th century had emerged. However, people on the basis of this theoretical study of solid materials have (more…)

For our current battery industry, the main problems is the environmental pollution and resource waste.

Is the environmental case, due to the battery industry’s production automation, mechanization level is not high, some township enterprises or even mostly by hand, lead to the production of polluting Guo Cheng, pairs of workers, a large physical hazards. Battery industry has been (more…)

Since the inception of lithium-ion battery, anode material related research mainly in the following categories: carbon materials, graphite, amorphous carbon materials, nitride, silicon-based materials, tin-based materials, new alloys, nano-oxides and other materials. As anode material for lithium ion batteries have the following performance requirements: (more…)
