For decades, we have heard about breakthroughs in battery technology, but cost-effective and safe mass production is a different matter, and there is a lot of competition between the West and the People’s Republic of China, which dominates the entire battery industry. Lightning charging is not an issue today, because there is a 300 watt transmission and of course a 22000 mAh mobile battery from China. But there are also improvements in terms of cycle life and volumetric energy density, but it doesn’t always pay off in mass production, or only a few units roll off the lines.
Honor’s new development is likely to be produced with a low output and will remain in China for the time being due to the complications of the Western licensing process, but the point is that with advances from the anode side, the Magic5 Pro in China offers a 5450 mAh battery with a 12.8% higher energy density , which means 6.8% more capacity compared to the 5100 mAh battery of Western models. A battery very simply consists of a negative (anode) and a positively charged electrode (cathode), a separator that separates them and a liquid electrolyte that ensures the free flow of lithium ions, plus an outlet for the movement of electrons.
In the anode of a typical mobile battery, graphite collects lithium ions – one for every six carbon atoms -, but silicon can do more, except that the collection of lithium ions involves a significant increase in volume, which is why manufacturers are cautiously “doping” the cathode with silicon for the time being, and carbon atoms are also used for greater structural stability mix to the recipe. Honor does not exactly detail the structure of the battery of the Chinese Magic5 Pro, in any case it uses the silicon-carbon indicator for the anode (silicon carbon), and whether pure silicon or only mixed with graphite, the anode grew with a higher energy density. In addition, with a low charge and voltage (3.5V), the phone can use more of the remaining energy as an emergency reserve compared to the purely graphite anode. It is obviously a matter of time to find out whether Honor’s new solution is completely flawless and safe, or whether the use of silicon negatively affects the cycle life (but the batteries that go into the products undergo very serious testing), nevertheless, every extra mAh is worth it these days, and an emergency reserve can also be a lifesaver.
