Amid the rapid development of the new energy industry, lithium - ion batteries, as the core energy carriers, have always been confronted with the key contradiction between "capacity" and "weight". Whether it is the range anxiety of electric vehicles, the transportation challenges of energy storage equipment, or the battery life limitations of portable electronics, all are closely related to the weight of lithium - ion batteries and their supporting structures. However, the material innovation of "same power, 1/6 the weight" is bringing a revolutionary transformation to the lithium - ion battery industry. Instead of directly changing the battery's chemical system, it reconstructs the "bearing framework" of lithium - ion batteries, allowing the battery energy to truly "operate with light loads".​

For electric vehicles, the weight of lithium - ion batteries usually accounts for 20% - 30% of the total vehicle weight. This not only increases the load on the power system but also directly restricts the improvement of the driving range. The battery packs of traditional electric vehicles mostly use steel or aluminum casings, and the weight of the casing alone accounts for 15% - 20% of the total weight of the battery pack. After adopting the new "1/6 weight" composite material, the situation has fundamentally changed. Test data from a certain automaker shows that for a vehicle model equipped with a lithium - ion battery of the same capacity, after replacing the battery pack casing with a composite material, the overall weight of the vehicle has decreased by 8%, and the comprehensive driving range has increased by 12%. More importantly, the impact resistance of this composite material is 3 times higher than that of steel. In the event of a collision, it can better protect the lithium - ion battery cells and significantly reduce the risk of fire. This is exactly the ideal state of "achieving both lightweight and safety" that the electric vehicle safety field has been pursuing for a long time.​

In the fields of portable energy storage and consumer electronics, the empowerment of lightweight materials to the application of lithium - ion batteries is also remarkable. For traditional portable energy storage power supplies, in order to ensure structural strength, their casings and internal brackets mostly use heavy metal components, resulting in a relatively large overall weight of the equipment and inconvenience in carrying. After adopting the "same power, 1/6 weight" composite material, the weight of a portable energy storage power supply with a capacity of 1000Wh can be reduced from the original 8kg to less than 5kg, while the structural strength remains unaffected at all. For consumer electronic products such as smartphones and laptops, the lightweight of the packaging materials for lithium - ion batteries is a key factor in directly improving the user experience. The weight of a lithium - ion battery packaged with a composite material is about 10% less than that of a traditional aluminum - cased lithium - ion battery. This means that under the premise of maintaining the same battery life, the thickness of a smartphone can be reduced by 0.3 - 0.5mm and its weight can be decreased by 5 - 8g, making the lightweight and thin design no longer at the expense of battery life.​

From the perspective of industrial costs and sustainable development, lightweight materials also provide a new path for the whole - life cycle optimization of lithium - ion batteries. In the production link, the processing energy consumption of composite materials is 40% lower than that of metal materials, and the molding process is simpler, which can reduce the production time and cost of the supporting components of lithium - ion batteries. In the transportation link, the reduced weight of lithium - ion batteries and their supporting equipment means lower energy consumption per unit transportation volume and reduced logistics costs. Taking the transportation of lithium - ion battery packs for electric vehicles as an example, a 10% reduction in weight can lead to an 8% - 10% reduction in transportation costs per 1000 kilometers. In the recycling link, some composite materials can be recycled, and the pollutants generated during the recycling process are fewer, which is highly consistent with the green and environmental protection attributes of lithium - ion batteries.​

The material innovation of "same power, 1/6 the weight" is breaking the traditional perception that "weight, performance, and safety cannot be achieved simultaneously" in the application of lithium - ion batteries. It not only makes the application of lithium - ion batteries in fields such as electric vehicles, energy storage, and consumer electronics more competitive but also promotes the entire new energy industry to develop in the direction of "lighter, safer, more efficient, and more environmentally friendly". With the continuous maturity and popularization of this technology, in the future, we may see electric vehicles with a driving range of more than 1000 kilometers and a weight equivalent to that of traditional fuel - powered vehicles, portable electronic devices that can be easily put into a backpack and have a battery life of up to one week, and large - scale energy storage power stations that are easier to deploy. All of this starts with the redefinition of the balance between "lightweight" and "high performance".
