South Korean professor Jaephil Cho (and, of course, a team of his students) from Hanyung University have developed a lithium-ion battery that lasts eight times longer than the actual models do.
Quantumsphere, on the other hand, presented last september a Li-Ion battery that lasts five times more than traditional ones.
Cho’s invention is seemingly kept in secret, but some say that the dramatic increase in the battery’s life is due to replacing the graphite in the battery with 3D porous silicon particles, which seem to keep more of the charge.
Anyway, more details have to appear before one can take this news for granted, and maybe invest in it. Further investigations have to be made (especially financial ones), to be sure that it is a feasible invention, and it does not charge the final user eight times more.
This is a short piece of news. I don’t know why everybody in the blogosphere keeps it so short, but they do (I begin sounding like Wikipedia)! If you know any other information, please feel free to share it with us, through the comments section below. Thanks.

New Fuel Battery Has 3 Times More Energy Than Gasoline!It’s not breaking news anymore, but some scientists from the University of Massachusetts, Boston, and others, led by Stuart Licht, discovered a battery that could kick out fossil fuels at the chapter of energy storage capacity.
EnerDel to Make Longer Lasting, Cheaper Li-Ion Batteries by 2010EnerDel, a company who has been on the market since 2004, makes serious promises about more efficient lithium-Ion batteries (LIB) to be manufactured in the very near future. They’re planning to make 300,000 of them by 2010. They also say that their batteries keep their charge capacity for up to 300,000 cycles, or 10 years of life.
Taiwanese Chlorophyll Battery – Works With Any Liquid!Chungpin Hovering Liao from Graduate School of Electro-Optic and Material Science of National Formosa University in central Taiwan discovered a battery that he claims to be the world’s first chlorophyll organic battery. He says his battery can be filled up with almost anything, including water and urine, and it can provide electricity from two to seven days.
Harvard`s Black Silicon: 100 to 500 Times More Powerful Than Old Solar CellsKept in secret until yesterday, a newly appeared company, named SiOnyx, unveils an invention of some Harvard researchers, that is going to revolutionize the whole industry. Harvard has been studying their “black silicon” for almost ten years, but nothing has come out of their lab, due to internal policies regarding the output of their discoveries to commercial companies.
