除了材料及电芯本身设计。在模组方面，通过排气通道，电芯间隔热及模组密封设计解决模组层级的热失控安全问题，模组只冒烟不起火；
电池系统安全设计方面，通过模组间热阻隔及排气设计，解决系统层级的热失控安全问题，同样保障了系统“只冒烟，不起火”。
近年来，国轩高科始终坚持技术型企业定位和“做精铁锂、做强三元”的战略规划。在做精铁锂产品的同时，持续发力三元，此次302Wh/kg的量产，即是公司在三元电池领域研发与实力的写照。
据电池中国了解，目前国轩高科已为302Wh/kg高镍三元电池建成了 1GWh智能化工厂。该智能化工厂引入了超宽度双面涂布系统、超快速叠片式卷绕系统等。
此外，公司技术团队还开发了动力电池化成系统及超快动力电池活化工艺，并结合MES系统自主开发全过程产品追溯系统，构建浆料均制模型，实现极片烘干过程中粘结剂与导电剂网络垂直极片方向的高度一致性，开发动力电池制造过程清洁系统及动力电池老化技术，并结合动力电池系统多级安全保护机制，实现电池产品的智能化及安全制造。
据国轩高科相关负责人介绍，能量密度302Wh/kg电芯的成功开发与应用，为公司下一代能量密度突破360Wh/kg电芯开发提供了经验和技术积累，公司将通过原材料和电芯技术的持续迭代升级，以及智能化生产设备等技术的进一步提升，为国内和国际高端客户提供更高端的电芯产品。
(11.15 news), recently, the high-nickel ternary battery with an energy density of 302Wh/kg has begun mass production at Guoxuan High-Tech. It is reported that this battery has been equipped with a variety of mid-to-high-end electric models, and the system energy density of related models has easily exceeded 200Wh/kg.
Dongfeng Junfeng pays great attention to the innovation and application of this battery technology, and will arrange the application according to the actual development of the company's vehicles.
Related information is as follows:
As the country's first mass-produced product and installed in a variety of mid-to-high-end vehicle applications, Guoxuan Hi-Tech may lead the industry to reach the threshold of 300Wh/kg for the energy density of single batteries, further eliminating people's anxiety about the endurance of electric vehicles.
It is reported that Guoxuan Hi-Tech 302Wh/kg high-energy density battery is realized through a variety of ways such as battery material innovation, lightweight design, and process optimization. "While keeping the volume of the battery pack unchanged, lightweight and other technologies are used to reduce the thickness and weight of auxiliary materials, increase the proportion of active materials, and greatly increase the energy density, which can be as high as the energy density of the existing mainstream ternary batteries. 25%, so that the vehicle has a longer cruising range.” said the person in charge of related projects at Guoxuan High-tech Industrial Research Institute.
In terms of cathode materials, the technical research and development team of Guoxuan Hi-Tech has achieved the stability of high nickel cathode materials through uniformity technology, doping technology, nano surface modification technology, and growth control technology of lithium intercalation and desorption. Cycle performance of nickel cathode material;
In addition, through the construction of a "dot-line-surface" conductive network based on the positive and negative pole pieces, the overall battery rate and cycle performance are improved.
In fact, the energy density breaking through 300Wh/kg is not the only major highlight of this battery.
In terms of safety, Guoxuan’s high-tech R&D team designed non-flammable fluorinated solvents and ionic liquid additives based on molecular simulations. The side reactions between the negative electrode materials greatly improve the safety performance of the full battery.
In addition to the material and the design of the battery itself. In terms of modules, the exhaust channel, battery cell insulation and module sealing design solve the safety problem of thermal runaway at the module level, and the module only emits smoke but not fire;
In terms of the safety design of the battery system, the thermal barrier and exhaust design between the modules solve the safety problem of thermal runaway at the system level, and also ensure that the system "only smokes, no fire".
In recent years, Guoxuan High-Tech has always adhered to the positioning of a technology-based enterprise and the strategic plan of "making iron and lithium and strengthening the three yuan". While making refined iron and lithium products, we continue to make efforts to ternary. The mass production of 302Wh/kg is a portrayal of the company's R&D and strength in the field of ternary batteries.
According to Battery China, Guoxuan Hi-Tech has built a 1GWh intelligent chemical factory for 302Wh/kg high nickel ternary batteries. The intelligent chemical factory introduced an ultra-wide double-sided coating system, an ultra-fast laminated winding system, etc.
In addition, the company’s technical team has also developed a power battery formation system and an ultra-fast power battery activation process, combined with the MES system to independently develop a product traceability system throughout the entire process, and build a slurry homogenization model to realize the bonding and The conductive agent network has a high degree of consistency in the vertical pole piece direction, develops a cleaning system for the power battery manufacturing process and power battery aging technology, and combines the multi-level safety protection mechanism of the power battery system to realize the intelligent and safe manufacturing of battery products.
According to the relevant person in charge of Guoxuan Hi-Tech, the successful development and application of energy density 302Wh/kg batteries has provided experience and technology accumulation for the company's next generation energy density breakthrough 360Wh/kg battery development. The company will use raw materials and battery technology. The continuous iterative upgrade of the company, as well as the further improvement of intelligent production equipment and other technologies, provide higher-end battery products for domestic and international high-end customers.
