--Starting from the material revolution behind the Xiaomi SU7 Ultra hit
When the "armor coating" bottom guard plate of Xiaomi SU7 Ultra triggered heated discussions in the industry, the polymer carbon nanocomposite protective materials of Zhongpo New Materials are reshaping the old pattern of battery protection for new energy vehicles with disruptive technology.
1. Behind the anxiety of power battery safety: the "Achilles' heel" of traditional protective materials
During the decade of the new energy vehicle industry, battery pack protection has always been the sword of Damocles hanging over the heads of car companies. Although traditional aluminum alloy guard plates can cope with daily scratches, they expose fatal shortcomings in extreme scenarios:
- Insufficient impact resistance: Bottom stone strikes and bottoming accidents can easily cause deformation of the battery pack structure and cause thermal runaway;
- Explosion-proof shortcomings: Puncture protection relies on multi-layer redundant design, sacrificing endurance and lightweight;
- Corrosion hazards: High salt fog in coastal areas and snow-melting agent environments in the north accelerate the aging of metal guard plates;
- High temperature fragility: Traditional flame retardant materials fail quickly in open flame scenarios above 800℃.
The breakthrough of Zhongpo New Materials is to directly hit these industry pain points and open up a new solution path with the bottom-level innovation of materials science.
2. Decoding Zhongpo New Materials' "Black Technology": Three-dimensional performance reconstructs the logic of battery protection
1. Military-grade impact resistance: turning the battery pack into a "bulletproof armor"
Zhongpo Materials has achieved revolutionary breakthroughs in fracture toughness and energy absorption rate indicators of new polymer composite materials made by chemically grafting carbon nanotubes. In the bulletproof test, a 5mm thick steel plate was sprayed with 2mm Zhongpo New Materials' polymer carbon nanomaterials and was not penetrated at 6 points of live ammunition.
2. Super anti-corrosion "Golden Bell Cover": Realize long-lasting rust-free protection
Relying on gradient densification technology, the corrosion rate after 10,000 hours of salt spray test is only 1/20 of that of traditional coatings.
3. Flame retardant and high temperature resistant: breaking through the 800℃ life and death line
When the industry generally pursues V0-level flame retardancy, Zhongpo Material's polymer carbon nanomaterials achieve flame retardancy at high temperatures of 800-850℃, and self-extinguish when away from fire, which can be called the "thermal insulation barrier" of the battery pack.
3. Leader in comprehensive solutions for all-round protection of new energy vehicles: Zhongpo New Materials' industrial ambition
At a time when the competition for new energy vehicles has entered the "second half", Zhongpo New Materials continues to innovate in the field of power battery protection for new energy vehicles, and has launched a number of new products with the all-round protection concept of "from the outside to the inside, from the outside to the inside", building a full-area protection matrix for new energy vehicles. At the 2024 Zhongguancun Forum, the interfacial super-assembled carbon nanocomposite material for the field of lithium-ion battery separators jointly developed with Fudan University was released. This patented product can effectively improve the mechanical efficiency of battery separators, enhance battery safety, and extend the battery life by about 40%.
When Xiaomi SU7 Ultra owners admire the aesthetics of technology, they may not notice the "invisible armor" under the car. However, it is the technological breakthroughs of "behind-the-scenes heroes" such as Zhongpo New Materials that are driving the new energy vehicle industry to cross the safety gap. In this wave of material revolution, Chinese intelligent manufacturing is rewriting the standard definition of global automotive safety with its hard-core technological strength.
