Trumony firması ile 2006 senesinde tanıştık. İlk tanışmamızda firmanın daha yeni kurulduğunu, genç ve dinamik insanlar olduğunu fark ettik. İlk günden kazandığımız güven duygusu 13 sene sonunda gördük ki bizi yanıltmamış. Profesyonel yönetim kadrosu ve ekibi ile yurtdışında rastlanabilecek firmalardan biri olan Trumony firması Uzak Doğu'nun Alüminy

As you have said the economy after the lockdown go on slowly. We have no idea which will be the future. Many economists say that the world start a new changed process. The economy as we know it will be not the same in the future.I think it too.In the meanwhile we only can do our best.Thanks for your support.Every efforts we do, now more than ever

Aluminum air battery's energy density in practical use

The theoretical energy density in case of Aluminium  Air battery is 8000 wh/kg, why Practical basis we can reach the minimum of 1300 wh/kg ?

The theoretical energy density in case of Aluminum - Air battery is 8000 wh/kg which is calculated from the energy of aluminum(26.8Ah/27g*2.7V*3e-=8.04wh/g(80400wh/kg)) without other anything. However, the battery contains positive, negative, electrolyte, other parts and so on, Therefore, the actual energy density is much lower than the theory. Aluminum air battery is a chemical reaction power generation, with conversion efficiency (Carnot cycle), so it will be far lower than the theoretical value.
For example, the actual available power of our single battery is only 1000Wh (Al is 300g,the theory is 2400wh/kg), the cell is about700g, and the energy density is 1400wh / kg without electrolyte. In this way, it has no guiding significance in practical application. The 300-400wh / kg we mentioned is the energy density of our actual aluminum air system products.latest company news about Aluminum air battery's energy density in practical use  0
