High Capacity Green Energy Storage Device from Native Weed Biomass

Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)
  • The agriculture invasive weed, Parthenium hysterophorus is one of the world’s most destructive invasive species abundantly found biomass species, threatening biodiversity, food security and human health across numerous The herb is native to Central and South America but has spread to over 40 countries over recent decades including India, Australia, India, Ethiopia, Swaziland and South Africa.
  • YES, our proven materials fabrication process is easily scalable with outstanding electrochemical performance as elec- trodes in both supercapacitors and rechargeable batteries.
  • We are deeply involved in improving and stabilizing the materials performance after deep analysis of capacity/capaci- tance failure mechanisms in coin cell and sandwich type pouch cell configurations and task specific modification thereof.
  • We have fabricated different biomass composites in grams scale and are in a process to implement them in field testing with close collaboration industrial Considering the potential of our fabricated materials in energy applica- tion we request further support from BPCL.
  • Hysterophorous to porosity enriched ultrahigh surface area activated carbon with a surface area of 4014 m2/g and a large porous volume of 0419 cm3/g.
  • Electrochemical studies revealed that the supercapacitor device assembled using the as prepared carbon material mani- fest a significant specific capacitance of 270 F/g, exhibiting excellent capacity retention of 98.5 % even after 30,000 cycles at an increased current density of 10 A/g.

Key Outcomes

The global supercapacitors market size was valued US$ 5 billion in 2022 and expected to hit US$ 25 billion by 2030, growing at a CAGR of 23.5% from year 2022 to 2030. Considering India is the fourth largest automotive maker and third largest energy con- sumer in the world, it is estimated that the supercapacitor market will grow by more than 16 percent compound annual growth rate in the next five years with a market size of $5 billion.

Current Status:

  • Currently, most electrochemical storage devices like Supercapacitors (SPs) are mostly used in transportation and energy solutions such as automotive industry, hybrid transportation systems around the world, grid stabilization, utility vehicles, and rail-system power models
  • SCs up to 150 F/g of capacitance, with a voltage of 2.7, and peak current at 65 A. has been considered as the world’s highest output power, with a discharge of 50 W per piece has been used in energy harvesting, extended energy-storage systems, and consumer electronics
  • Another major application widely used is with fuel cells for maximized energy storage and rapid charging capabilities
  • Futuristic Applications
  • Supercapacitors with hybrid character can be a effective alternative Research at lab scale has shown the potentials of supercapacitor battery which can take up a fraction of the space of lithium-ion cells, charges more quickly, and can be best of Coulombic efficiency with recharges reaching 30,000 cycle and still working like first cycle
  • Further, innovative efforts are going on to create ultra-light weight at the same time reaching storage capabilities 150 F/g and 550 F/g, using biomass-based Grapheneous/ Carbonaceous materials are being explored
