French researchers have already published a prototype of a working sodium-ion battery that may pave the way for new rechargeable batteries that are less expensive than current lithium-ion batteries.
The use of sodium to produce batteries is not new, but the development of this technology gave way to lithium-ion battery technology decades ago, because in theory lithium-ion batteries can provide more power.
LilipuTIng said, however, that researchers at the National Center for Scientific Research in France have developed a prototype of the 18650 battery that is comparable to some lithium-ion batteries in terms of capacity and time of use. This may pave the way for the commercial development of sodium-ion batteries.
Compared to lithium materials, sodium materials are cheaper to produce and more abundant in nature, but they are denser, which means that sodium-ion batteries may not be suitable for lighter weight devices such as cell phones, tablets and Notebook, but it may be suitable for large products with little impact on electric cars and other battery weights.
According to LilipuTIng, sodium-ion batteries can also be used in large-scale battery packs to store electricity from solar or wind power plants, and to supply electricity when the sun goes down or when the wind is not strong enough.
Chinese Tier 1 brand Solar Panel (Longi, Jinko, Trina, Canadian, Ja etc.)
This type of product is mainly Tier 1 solar module product in China, include Longi solar panel. Jinko solar panel, Canadian Solar panel, ja solar panel etc.all of which are among the top 10 world-renowned brands. The original A grade product is mainly mono crystalline and half cut cell solar modules, with a power range of 400watts to a maximum of 700watts.quality warranty is 25 years.
A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
