Polymer lithium-ion batteries in 1999, Japan took the lead in industrialization. China has also started the production, such as Xiamen Baolong Battery Co., Ltd. and Guangdong Huizhou TCL King to Battery Co., Ltd. has begun production. At present the company for the production of polymer lithium-ion battery is not exactly the same route, and these companies are not to be too much of these technologies open. The following Read More…

Currently used in rechargeable lithium-ion battery There are two ways: constant current charging and constant voltage charging, of course, carried out between the two can cross. The former is mainly used for laboratory research, which is less used. In the constant current charging process, the threshold voltage increases quickly, the general capacity increases linearly with time, the internal resistance also increases. Read 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: Read More…

In the TG, DTA and other thermal analysis techniques, testing conditions often have greater impact on the results. For example, the sample volume, sample shape and accumulation conditions, heating rate, furnace atmosphere, and affection are TG, DTA curves of the shape and location. Therefore, regardless of the thermal spectrum in the test and analysis should be given adequate attention when. Read More…

Solid electrolytes include two categories: inorganic electrolyte and polymer electrolyte.

Inorganic electrolytes in selecting Read More…

Lithium-ion battery cathode material is usually embedded compound as an ideal cathode material, lithium intercalation compound should have the following properties:

① metal ions embedded in compounds with higher r Read 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 Read 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 originated in the beginning of this century. After a very long era, the structure of carbon materials is the solid (crystal) structure of the field Read More…
