Partially carbonised carbon fibres are engineered to resolve the traditional trade-off between mechanical strength and energy storage in structural batteries. By utilizing tailored, lower-temperature thermal processing, these fibres achieve up to 40%better electrochemical performance than conventional fibres while maintaining critical structural integrity.

Partially carbonised carbon fibres are engineered to resolve the traditional trade-off between mechanical strength and energy storage in structural batteries. By utilizing tailored, lower-temperature thermal processing, these fibres achieve up to 40%
better electrochemical performance than conventional fibres while maintaining critical structural integrity. 

Key Breakthroughs & Mechanics
Processing Temperatures: -
Fibres manufactured at maximum carbonisation temperatures between 800∘C and 1100∘C exhibit a highly optimized microstructure for electrochemical activity without entirely sacrificing their tensile modulus.
Multifunctionality: -
Standard commercial fibres are optimized solely for mechanical load. Partial carbonisation breaks the traditional antagonistic dependence, allowing the fibres to act efficiently as both structural reinforcement  (load-bearing) and electrochemically active material (anode).
Performance Gains:
   Recent studies (a collaboration between Chalmers University of Technology and Deakin University) show these partially processed fibres deliver higher reversible capacity and vastly improved cycling stability.
In electric transportation and aerospace, vehicle weight is a critical bottleneck. Structural batteries embed energy storage into the vehicle's physical chassis or panels. By using partially carbonised carbon fibres, engineers can significantly reduce system weight while retaining the mechanical strength required for rigid, load-bearing applications.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
