Company works to external batteries with barely capacity degradation




The company Gbatteries is working on a new management system for battery packs, which ensures that the capacity after five years of use and three thousand cycles of charging and discharging is decreased only by 4. Percent In the autumn the first charger for MacBooks and mobile devices to come out.

Technology Gbatteries , founded by a father and son from Ottawa, Canada, called BatteryOS. It is a management system for ordinary lithium-ion batteries, which will make better use of the material is made ​​and formed, for example less passive sei-layers. One of the two inventors described that were last month told The Globe and Mail as “plaque”: “As time goes on, it grows low and it prevents the battery can be charged as much as before.”

The system runs on a self-designed circuit board and would extend life by “eliminating concentration polarization”, so the “lithium-ion uniformly extracted can be re-injected into the cathode material or. In addition, the capacity would be increased from the standard energy density of 100 to 125Wh/kg the current lithium-ion batteries to 110 to 175 Wh / kg. The father and son have a patent pending on their invention.

The first product of the company is the batterybox , which should come out in the fall in the amount of $ 139. The square accessory is designed for charging MacBooks, is slightly larger than the standard supply of Apple laptops and has a capacity of 50Wh, that a MacBook Air about an additional 12 hours, and a MacBook Pro can function, 6 hours longer depending on the model.

Besides a MagSafe2 connection the batterybox features a USB socket for charging mobile devices. The battery itself is recharged via micro USB, so it can be before it is fully charged, in combination with a power of 1 ampere 9 hours at a 2A power supply would be half.

It is unclear whether Gbatteries a license to use the MagSafe connector. Another maker of external batteries for Apple products, HyperMac with its Hyper Juice batteries, got it undertakes to stick with the manufacturer from Cupertino, Apple Insider wrote in 2010.

Gbatteries would not leave it with external batteries for MacBooks, but improving batteries of all kinds of devices, from laptops to electric cars, writes TechCrunch. Concrete announcements in these areas are not there yet. The tech industry has been trying to force on battery field, breakthroughs times but is taking against numerous problems, as described Tweakers last year in the background article “Where are our super batteries?” Gbatteries is not the only one that is focused on the improvement of the charging, discharging, and the life of laptop batteries. Qnovo do this, for example. This company describes its technology in more detail in a document .
