Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium-ion batteries use carbon materials as negative electrodes and lithium-containing compounds as positive electrodes. According to different positive electrode compounds, common lithium-ion batteries include lithium iron phosphate, ternary lithium, lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, etc.

Lithium ion battery works on the moving of Lithium ion between positive and negative electrode. During the charging process, Li+ is embedded and umembedded between the two electrodes: Li+ is umbedded from the positive electrode and embedded into the negative electrode through the elecrtolyte while charging, and the negative electrode is in a lithium-rich state. The opposite is true for electrical discharge.

Lithium battery structure and principle interpretation

Now the relatively common and highly recognized by the public of lithium battery are mainly NMC and LiFePO4 . So, how to distinguish between the use of the battery is a NMC and LiFePO4 batteries? The following is a brief introduction to the method.

the battery service life is greatly related to the user’s daily maintenance.

Do you know When is the best time to change batteris for electric vehicles with cheapest price? Which electric bicycle battery is more durable?

With the development of science and environmental protection, vehicles gradually transform from oil-fueled driving to electric driving. In the future, the new energy vehicles will be gradually spread to the masses. The alternative to fuel oil, of course, is batteries, at the stage, the widely use of vehicles power batteries include nickel metal hydride battery, lithium ion battery, nickel cadmium battery and lithium battery.

In 26th Oct morning, Grand Elite Club, with the theme of "Enter into famous enterprises and learn from benchmarking enterprises", a Fujian study tour group entered arrived in Better Technology Group Limtied (hereinafter referred to as Better Group). Mrs Wei (President of Better Group), together with all the middle and senior managers of Better Group, extended a most sincere welcome to all the entrepreneurs who came from different cities.

Lithium iron phosphate has the characteristics of long life, safe use, large capacity, green environmental protection, etc., and its demand continues to increase in the fields of power batteries and energy storage. At present, the energy storage system with lithium iron phosphate batteries has become the mainstream choice in the market. In the first seven months of 2022, China's domestic lithium iron phosphate energy storage accounted for more than 90% of the electrochemical energy storage field.

LiFePO4 is poor in electrical conductivity because of the low diffusion coefficient of Lithium ion. The current approach is to make the particles smaller or even nanoscale. Through shortening the migration path of Li+ and electrons, the speed of charging and discharging is increased (theoretically, the migration time is inversely proportional to the square of the migration path). But this brings a series of difficult problems to battery processing. Let’s take a look at how to solve the problem of coating uniformity of lithium iron phosphate battery .

​Besides lead-acid battery, there are still some electric cars using lithium batteries, but when replacing lithium batteries, we found that noboday wants to use old lithium batteries, why does this happen?

This means that Better Group's existing management system, product quality, environmental quality, etc. have been recognized by the International Organization for Standardization, which could meet the product quality requirements and standards of the international market, and continuously and steadily provide customers with high quality products and high quality services. This is another very important milestone in the development process of Better Goup.
