Laptop and cellphone batteries could ascertain a multiple promote in performance if a technology breakthrough from scientists in the United States comes to realisation.
That means we can get the best laptop battery life in the near future.
According to researchers at the Massachusetts Institute of Technology, replacing conventional battery electrodes with those surfaced with carbon nanotubes can drastically increase the power to weight ratio compared to conventional lithium-ion batteries.
The scientists sound out they made the powerful new electrodes by as an alternative dipping a base material in solutions containing carbon nanotubes with positive and negative charges to make a stable film coating.
The effect is an electrode that is more poriferous and includes a lot of oxygen groups, which can stock a lot of lithium ions.
According to the scientists, the energy output for a given weight of this new electrode material was five times greater than for original capacitors, and the entire power delivery rate was ten times that of lithium-ion batteries.
As well their high power output, the researchers claim the carbon nanotube electrodes were extremely stable showing no change in performance over 1,000 charge cycles.
While carbon nanotube production is presently restrained to niche suppliers, several companies are gearing up for mass production of the material.
