The 4680 battery started in September 2020, represents the size of the battery, with a diameter of 46 mm and a height of 80 mm，and its specific performance, depends on the internal cell and positive and negative electrode performance.

Recently, all members of Better Technology Group Limited assembled and officially held the ceremony of signing military orders and high-quality oaths for the goals of various organizations in Better Technology Group Limited in 2023. On the same day, all employees of Better Technology Group limited vowed to reach the annual goal with the determination to brave the wind and waves, playing the strong voice that Better Technology Group Limited is at the forefront and sets an industry benchmark. Facing the fierce battle, the high-quality development swearing-in meeting was successfully completed in the mighty declaration of the voices.

Better Group sincerely invites you for meeting at the Battery Energy Storage Indonesia to be held on Mar. 2nd~4th, 2023.

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.
