Cheaper, more rich reserves of potassium ion battery or become a dark horse

Source: 2020 - 04 - 01 'hits: time for the leading position of lithium-ion batteries, cheaper and more abundant potassium ion battery or become the limit of the dark horse company leading the lithium ion battery energy storage areas, mobile phones, electric car battery energy storage is a country with a lithium battery factory, but this does not mean that it can firmly to the throne, because of the safety of the lithium ion battery, capital is higher, there are many scientists are looking for alternatives, scientists in the United States now cheap, potassium content more rich crust batteries. When potassium content about 2 in the crust. 09%, ranked seventh, production costs and data costs less than lithium, the United States institute of technology ( RPI) Thinks, if the use of total potassium metal anode, regardless of size or components of energy density, energy density can be compared with the lithium ion battery, battery capacity is high. But the potassium ion battery and lithium ion battery is the same, there is also the question of dendritic growth, usually brief lithium-ion batteries in charging and discharging lithium ion imbalance in the process of the electrode appearance will eventually because of the accumulation of dendritic lithium dendrites form, these dendritic briefly breached insulation, eventually led to the battery fire, lithium and the activity of potassium is higher than the melting point is 68 degrees Celsius, is actually a kind of flammable and explosive substances, there are a large number of elaborate processing on security. RPI team claimed that they have a magical 'self correction technology, after a whole night charge, can automatically remove the anode dendrites, prevent the excessive growth. Team points out that, through the accurate control of temperature of the battery in a controlled environment and advance to the appropriate temperature, the metal potassium won't melt, cloth will distract, from potassium atom clusters and dendrites dendritic evenly. This situation is a bit like a sunny day, after the storm the wind blowing in the wind, the sun will gradually atrophic, finally gradually smooth, machinery, aerospace and nuclear engineering Nikhil Koratkar professor pointed out that there is no battery, just turn the battery processing system, promote local heat, make self - battery modification。 The team believe that this is likely to make cheap aging of potassium metal cell commercialization. But it is not the first group watch battery self modification conditions, as early as in 2018, they found that can be in the same way, proposed the temperature flattening dendritic lithium battery, and a new discussion in addition to found that potassium can be used in battery, perhaps to avoid overheating to speed up the battery is on the decline, so as to discuss battery processing system plan is put forward.
