The autonomy has always been one of the strengths of Macs but like its competitors, especially in mobile, Apple is working on new battery technologies, particularly to replace the lithium-ion. And his works seem advance since Apple has filed a patent to provide a battery life of several days or even weeks … The dream. The patent in question was published by the website of the Office of US patents.
Like others, Apple attempts to develop hydrogen fuel cell system and miniaturized sufficiently stable to be embedded in a computer. The patent also stresses that “it is extremely difficult to develop fuel cell systems for portable hydrogen sufficient and economically viable for use in electronic devices.”
In addition to hydrogen, Apple’s patent indicates that the fuel cell could be used sodium borohydride, sodium silicate or lithium hydride. Or be associated in addition to a conventional battery, much like an electric motor that takes over a conventional engine in a car
now remains whether this patent will be operated commercially by Apple.: questions remain in effect: mass production, ecological impact of these new processes. Or if this patent will remain in a drawer, as many patents Apple …
Scientists and manufacturers: all are working on batteries that are now the weak point of our connected devices. Google, through its Google X laboratory, would work in secret
two years on new technologies related to this component
sensitive.
According to the WSJ, the project would be led by Dr.
Ramesh Bhardwaj, a specialist in storage, which notably
worked for Lockheed Martin and Apple. Four scientists would
part of the team. The idea is obviously to improve the autonomy of
Andrroid terminals but also: autonomy is a problem
Google Glass for central or autonomous cars.
Work would focus around the conventional technology
Lithium-ion (most used today), but engineers
also are working on other approaches as the solid electrolyte.
In April, it was scientists
Stanfordon who made about them by successfully developing a
functional aluminum-ion battery. The latter does not fail
advantages: aluminum is more environmentally friendly than litium, its
Use can fold the battery, extend endurance and
reduce time to recharge: one minute may be sufficient, the
mobinaute dream for any self-respecting.
Other benefits:
less propensity to heat (and thus to ignite), point becoming
prégnant in our smartphones, and reduced unit costs.
presented may issue a battery voltage of 2 volts and support
7500 charge cycles, first with aluminum. Remember that
traditional batteries “star” about 1000 cycles.
The team
led by Hongjie Dai explains chemist have passed this breakthrough
accidentally finding that graphite providing excellent
performance when coupled to aluminum, said in a
Stanford University news release.
In short, this approach
currently focuses only advantages but the question remains
always the same in R & amp; D: when an industrial transition,
advertisements in the small world of batteries being but many
concretisations actually quite rare.
