Where does the carbon footprint of a power battery originate, and where does it ultimately go?
time：2026-08-03
The carbon footprint of a power battery is much longer than we thought. It started from the cobalt-nickel ore deep in the mine, passed through the high-temperature furnace of the smelter, the clean workshop of the electric core factory and the automatic production line of the PACK factory, and finally imported into the drive motor of the electric vehicle, after several years, it entered the recycling and dismantling circulation channel. On the carbon management platform that gathers new energy sources, every battery pack carbon footprint is accurately tracked, quantified, and managed-this is not an environmental slogan, but a hard constraint on the regulations that will come into effect, it is also the strategic fulcrum of the core competitiveness of enterprises.
I. Where does carbon come from: disassemble a battery pack carbon bill"
the carbon footprint accounting of energy-gathering new energy sources covers the whole chain from "cradle" to "gate.
Upstream mining and smelting it is a major carbon emitter. Taking ternary lithium battery as an example, the mining and smelting of nickel, cobalt and manganese contributed 35%-45% of the whole carbon footprint. Gather Energy new energy and establish direct data connection with upstream mining enterprises to obtain carbon emission factors of each batch of raw materials. A batch of Indonesian laterite nickel ore is smelted by RKEF fire method, and its carbon emission factor is as high as 18kg co/kg nickel; While another batch adopts HPAL wet process, carbon emissions are reduced to 8kg CO/kg nickel. Data transparency enables energy-gathering new energy sources to include carbon cost weights in procurement decisions.
made in cell it is the second carbon source. The processes of cathode material sintering, anode graphitization, electrolyte preparation, and cell formation depend on a large amount of electricity and heat energy. Energy gathering new energy requires strategic cell suppliers to provide process-level energy consumption data and promote their use of green electricity. At present, 60% of the core cell suppliers of energy-gathering new energy have achieved 100% green power coverage in the production process.
PACK integration the carbon emissions in the link are relatively controllable, but the new energy sources are still carefully calculated in every detail. Energy efficiency optimization of production line equipment, low-carbon formula replacement of structural adhesive, path planning of logistics and transportation-these "micro innovations" accumulate, the unit carbon emission of PACK is reduced by 22% compared with that of three years ago.
A "factory carbon footprint" of 80kWh lithium iron phosphate battery package is currently controlled at about 45kg CO kWh/kWh, which is better than the industry average of 65kg CO kWh/kWh.
II. Where does carbon go: closed loop from Echelon utilization to material regeneration
battery pack carbon footprint management, more than factory delivery.
Vehicle-mounted use stage
Echelon utilization it is the first stop of retired batteries. The new energy source has established a battery health status (SOH) evaluation system. Battery pack of the capacity decayed to 80% is retired from the vehicle and transferred to the energy storage power station for 5-8 years. This "second life" extends the whole life cycle value of the battery and reduces the carbon emission intensity per unit of electricity.
Recycling and dismantling is the last link of the closed loop. Juanneng New Energy has signed a long-term agreement with professional recycling enterprises to ensure the compliance disposal of retired battery pack. The lithium recovery rate of lithium iron phosphate battery has reached more than 90%, and the recovery rate of nickel cobalt manganese has exceeded 95%. Recycled materials re-enter the supply chain for new cell manufacturing, forming a "from mine to mine" cycle. The goal of gathering energy and new energy is to achieve 30% of the recycled materials of core metal materials by 2030.
3. Digital passport: make carbon footprint "visible, checked and trusted"
the EU's new battery regulations require that power batteries must be equipped with "digital battery passports"-a digital file containing carbon footprint, material sources and recycling information throughout the life cycle.
the new energy source was laid out two years in advance and developed a carbon management platform based on blockchain technology. From raw material procurement to cell production, PACK integration to vehicle loading, vehicle operation to decommissioning and recycling, the data of each link is uploaded in real time and cannot be tampered. You can scan the QR code on the battery pack to view its complete carbon resume ".
"Digital passport is not a burden, but a trust asset. "The director of sustainable development of energy New Energy said," when the carbon footprint is transparent, our European customers are willing to pay a premium of 5%-10% for low-carbon products. "
IV. Strategic value of carbon management: from compliance cost to competition barrier
in the strategic map of energy gathering new energy, carbon management has been upgraded from "compliance department" to "core issues of the whole company".
Regulatory compliance is the bottom line. The domestic content requirements of the European Union's carbon border regulation mechanism (CBAM), the US inflation Reduction Act (IRA), carbon emission intensity constraint under China's "double carbon" goal-major markets in the world are reshaping the trade pattern with carbon rules. The low-carbon capability of gathering energy for new energy directly determines its market access qualification and tariff cost.
customer Trust is an increment. More and more car companies have incorporated the carbon footprint of the supply chain into the purchasing scoring system, and low-carbon battery pack has become the key support for the carbon neutralization statement of the vehicle. Energy gathering new energy has provided three European car companies with carbon footprint certification reports to help them obtain the EU green premium.
Capital favor it's a lever. In ESG rating, the weight of carbon management continues to rise. The low-carbon practice of energy gathering new energy provides narrative support for its green bond issuance and ESG fund investment, and the financing cost is 30-50 basis points lower than the industry average.
One Piece power Battery the carbon footprint extends from the depth of the mine to the recovery furnace, spanning several years and thousands of miles of space. In the practice of gathering energy and new energy, carbon management is not an ornament of environmental public relations, but a systematic project embedded in supply chain, manufacturing process and product design. From the precise tracing of "Where does carbon come from", to the closed-loop management of "Where does carbon Go", and then to the commercial realization of "How much does carbon value", the new energy accumulation is proving: low carbon is not a cost, but a future-oriented investment.
