引言
在对可持续能源解决方案的持续探索中，中国取得了一项引人瞩目的突破，这一突破有望重塑全球能源格局。中国科学家研发出一种利用电活性微生物的生物电池，其高效能与自充电特性为传统电力系统提供了可持续的替代方案。这一创新不仅为更绿色的能源未来点亮了希望之光，也凸显了生物技术进步在实现全球碳中和目标中的关键作用。
The Ingenuity of Bio-Batteries: Harnessing Nature’s Power
At the heart of this remarkable development lies the concept of bio-batteries, which leverage biological systems to generate electricity. Unlike conventional batteries that rely on chemical reactions of rare earth metals, bio-batteries tap into the metabolic processes of microorganisms or enzymes to produce electrical energy. This aligns perfectly with the principles of circular economy and sustainability.
The specific Chinese innovation utilizes electroactive microorganisms, notably Shewanella oneidensis MR-1 biofilms, embedded within living hydrogels. These three-dimensional printable hydrogels act as a scaffold, encapsulating the conductive biofilms while maintaining their high viability, demonstrating over 70% functionality throughout their lifespan and an impressive 97.6% at their conclusion. The bacteria’s metabolic activity enables the continuous generation of electrons and the reduction of graphene oxide, facilitating a remarkable 99.5% coulombic efficiency and a self-charging mechanism that can endure up to ten cycles. This ingenious design allows for a precise electrical energy supply, all within the compact, familiar form factor of a standard 2032 battery shell.
生物电池的巧思：利用大自然的力量
这一非凡进展的核心在于生物电池的概念——它借助生物系统来发电。与依赖稀土金属化学反应的传统电池不同，生物电池利用微生物或酶的代谢过程产生电能，这与循环经济和可持续发展的原则完美契合。
中国的这项创新具体采用了电活性微生物，尤其是Shewanella oneidensis MR-1生物膜，并将其嵌入活体水凝胶中。这种可三维打印的水凝胶充当支架，包裹着导电生物膜，同时保持其高活性——在整个生命周期中功能保持率超过70%，末期仍可达97.6%。细菌的代谢活动可持续产生电子并还原氧化石墨烯，实现99.5%的库仑效率，且具备可维持长达10个周期的自充电机制。这种巧妙设计能精准供应电能，同时采用紧凑的标准2032电池外壳形态。
Environmental Stewardship: A New Era of Clean Energy Storage
The environmental benefits of this bio-battery technology are substantial and multifaceted, directly addressing many of the ecological challenges posed by conventional batteries:
• Resource Independence: Crucially, these bio-batteries operate without the need for critical raw materials such as cobalt, lithium, manganese, or problematic organic electrolytes. This eliminates the environmentally destructive and geopolitically sensitive mining practices associated with these elements, reducing habitat destruction, water pollution, and human rights concerns.
• Reduced Toxicity and Waste: By eschewing hazardous chemicals, bio-batteries are inherently more environmentally benign. They pose no risk of leakage or explosion and are easier to dispose of at the end of their life cycle, preventing toxic waste accumulation in landfills.
• Circular Economy Alignment: The biological components can be sustainably sourced, and their disposal is significantly less impactful, fostering a more circular approach to energy storage. The development of bio-based technologies for lithium recovery from spent batteries further exemplifies this commitment to circularity, as seen in research efforts in the EU.
• Lower Carbon Footprint: The production process of bio-batteries is generally less energy-intensive and produces fewer greenhouse gas emissions compared to traditional battery manufacturing, contributing to a lower overall carbon footprint.
环境管理：清洁能源存储的新时代
这种生物电池技术带来的环境效益是广泛且多方面的，直接解决了传统电池造成的诸多生态挑战：
• 资源独立：关键在于，这些生物电池无需钴、锂、锰等关键原材料，也无需使用有问题的有机电解质。这消除了与这些元素相关的破坏生态且涉及地缘政治敏感的采矿行为，减少了栖息地破坏、水污染和人权问题。
• 降低毒性与废弃物：生物电池通过避免使用有害化学物质，本质上对环境更友好。它们不存在泄漏或爆炸风险，生命周期结束后更易处理，从而防止有毒废弃物在垃圾填埋场堆积。
• 契合循环经济：生物成分可通过可持续方式获取，其处理对环境的影响显著降低，推动能源存储向更循环的模式发展。从废旧电池中回收锂的生物基技术研发（如欧盟的相关研究），进一步体现了对循环性的承诺。
• 更低碳足迹：与传统电池制造相比，生物电池的生产过程通常能耗更低，温室气体排放量更少，有助于整体降低碳足迹。
Application Scenarios: Diverse Possibilities
The inherent advantages of bio-batteries make them ideal for a range of low- and medium-power applications, where their safety, environmental profile, and unique properties are paramount. These include:
• Wearables and Smart Tags: Powering low-energy wearables, RFID tags, and smart sensors due to their flexibility and environmental safety.
• Remote Sensing and IoT: Ideal for off-grid environmental monitoring, agriculture sensors, and various Internet of Things (IoT) devices, offering reliable power in remote locations without requiring frequent maintenance or hazardous waste disposal.

For instance, in the case of cardiac pacemakers, unlike traditional lithium batteries that require regular replacement, the self – charging feature of bio – batteries can eliminate surgical risks and prolong device lifespan.
• Environmental Monitoring: Satisfies the self – power supply requirements of distributed sensors. It is especially suitable for long – term data collection in remote regions or extreme environments.
• Energy Networks: Has a more groundbreaking application prospect. When bio – batteries collaborate with renewable energy sources like solar and wind power, a “biological – renewable energy” hybrid energy storage system can be established, effectively reducing the issue of intermittent power supply. In microgrid scenarios, bio – batteries can function as stable base load power sources, supplementing the highly variable wind and solar power generation and enhancing the overall stability of the energy system.
