Especially after the car battery caught fire, people are more and more aware of the importance of battery safety.
At present, in order to meet the higher requirements of automobile manufacturers in terms of cost and quality, major battery suppliers are constantly updating their battery manufacturing technologies. Contemporary Ampere Technology Co., Ltd., LG Chem, BYD and other new energy battery giants have released new batteries, and launched a new round of competition around safety, cost and quality.
Recently, another company entered the new energy battery market, and the products it brought were completely different from the current products.
This is the first battery day held in Wuxi R&D Center earlier this month. This kind of cobalt-free battery and jelly battery are different from Tesla, Contemporary Ampere Technology Co., Ltd. and BYD.
It is reported that in order to solve the problem of thermal runaway fire of power battery, Honeycomb has developed a set of systematic "cold bee" thermal runaway solution, which intends to completely eliminate the possibility of its occurrence from these four levels (positive and negative materials, batteries, battery packs and system monitoring).
As for the cathode material, the cobalt-free material developed by it has achieved stronger voltage resistance and more stable structure through three key technologies: cation doping technology, nano-network coating technology and single crystal technology, which has brought longer battery life. Compared with NCM8 1 1, the thermal decomposition temperature, thermal runaway temperature and overcharge tolerance of single crystal cobalt-free battery are all higher than 8 1 1, and the cycle life is 65% higher than 8 1 1.
Jelly battery is a kind of lithium battery with jelly electrolyte. It has several advantages: first, it will not explode no matter how abused, and it has the characteristics of self-healing and high safety; Secondly, the four processes of conducting electricity reduce the cost of the battery.
Materials and battery pack design. On the material level, the cobalt content will be reduced and the battery will be cobalt-free. Moreover, the hive has developed platform E and platform H, with NCM8 1 1 above and lithium ferrous phosphate below.
On the battery PACK level, the module-free design is adopted, which reduces the weight of the non-value-added part of the pack, achieves 80% group efficiency under the premise of ensuring safety, and reduces the cost through integrated technology.
In the manufacturing process, the lamination process and dry coating process are adopted to enable AI intelligent manufacturing, improve production capacity and reduce costs.
According to the data of power battery capacity in September and June released by 10 this year, the installed capacity of honeycomb energy continuously entered the TOP 10 list. In addition to the current stable supply of Great Wall Motor, Honeycomb Energy has been expanding its customers for a long time, including many foreign companies, the largest of which is the French automobile company.
In order to keep up with the pace of business expansion, Honeycomb Energy has expanded its factories at home and abroad (Changzhou, China, and Saarland, Germany), and plans to hit the domestic power battery top3 next year.
At present, cellular batteries are further developing lithium battery technology, including all-solid-state batteries and capsule batteries. I believe that there will be more exciting technologies for cellular batteries in the future. With the display of product functions and the research and development of new technologies, there will be great breakthroughs in domestic and foreign markets.
