In addition, in northern China, due to the very low winter temperatures, new energy vehicles are extremely limited in their promotion due to their unbearable low-temperature batteries, and the low temperature test of the power battery of the Nugget has shown that The charge and discharge capacity of the battery at -40°C can reach more than 60% of the rated capacity, and after 400 charge and discharge at -20°C, the capacity attenuation does not exceed 3%. This means that lithium-ion batteries can also be used on a large scale in extreme temperatures such as in Northeast China and even in space. According to the R&D personnel of the League, the battery product was mainly renovated from the structural design. First, the laminated cell structure and electrode design were adopted, and the diffusion distance of lithium ions was shortened through high-precision process control. Improve the lithium ion diffusion rate, is conducive to the rapid charge and discharge of the battery; Second, the use of flat flexible packaging battery structure, making the battery temperature difference is minimized, the battery has a larger surface area, more conducive to cooling after warming, reduce the battery heat The risk of losing control is that the battery is safer in operation. In addition, the use of a structure with ears on both sides increases the width of the electrode that draws current from the positive and negative electrodes, and the current distribution is more uniform, making it easier to achieve high power output of the battery.

High rate fast charge
Low temperature characteristics 
Charge-discharge curves are not at the same temperature
Nugget pushes a new generation of power batteries to charge 70% of the battery in 1.7 minutes and normal use of minus 40 degrees Celsius
For a long time, the power characteristics (rapid charge and acceleration performance), durability of life, and temperature adaptability of power batteries are all key factors restricting the popularization and promotion of new energy vehicles. Recently, CITIC Guoan League Gugli Power Technology Co., Ltd. (hereinafter referred to as the "Oguli") announced that the company has developed a high-performance manganese-based ternary material lithium-ion battery, which has the rate characteristics and low temperature characteristics. Obviously improved, it can realize instant fast charge for 2 minutes and normal use at low temperature of -40°C.
  According to the data provided by the alliance, this 6Ah power battery adopts 100C large rate charging, only needs 6S to charge about 16% of the capacity, 1.7 minutes can fill more than 70% of the capacity, its charging speed can be The speed of refueling traditional fuel vehicles is quite high. Compared to supercapacitors, the large rate characteristics of lithium-ion batteries have been at a disadvantage. If the charging efficiency is achieved in practical applications, it means that lithium-ion battery will break in many applications where fast charging is required. Only supercapacitors can be used. Limitations.
However, related parties pointed out that the large rate of charge is likely to cause the problem of accelerated decay of lithium batteries. Wu Ningning, president of the Mongolian Research Institute, said that Ngali has done a lot of charge and discharge tests to simulate various charge and discharge environments, and the charge and discharge 400 After that time, there was no overspeed decay. Wu Ningning said that there is no 100C charging device on the market for the charging rate of the auxiliary charging equipment. Nuggi only tests the battery, and the battery can be mass-produced, but with the battery technology and market faster Driven by demand, the supporting charging technology will soon go to the market.
