Chinese scientists have developed a next-generation biohybrid battery that combines microbial energy conversion with electrochemical reactions, achieving a remarkable 99.1% efficiency rate. Developed by researchers at the Fujian Agriculture and Forestry University, the battery system uses a two-stage process: first, an electrolysis cell converts CO₂ into formic acid using electricity; then, genetically engineered bacteria within a microbial fuel cell consume the formic acid to produce electricity. This innovative system charges in just 3 minutes and delivers a continuous power supply for up to 25 hours—far surpassing traditional microbial batteries, which are often inefficient and slow to recharge.
What sets this battery apart is its sustainable design and real-world utility. It uses common, low-cost materials and doesn’t rely on rare metals, making it both eco-friendly and scalable. In trials, it was successfully used to power sensors detecting toxic pollutants like formaldehyde and copper in water, highlighting its potential for environmental monitoring and wastewater treatment. The research represents a major leap in sustainable energy, showing how biotechnology can be integrated with clean energy systems to address both energy storage and environmental challenges. More
