The reason why the liquid injection volume of the lithium battery cylindrical liquid injection machine is unstable is that the flow rate is too slow. Change the hose from thin to thick. If this is not necessary, keep the hose as short as possible. There are air bubbles in the body. Excessive fluid pressure combined with too short a valve opening time can cause air to enter the liquid. The solution is to reduce the fluid pressure and use a tapered needle.
Caused by overload. The softness of lithium iron phosphate batteries is caused by overcharging. The bulge caused by overcharging will cause all the lithium atoms in the positive electrode material to flow into the negative electrode material, causing the original complete grid of the positive electrode to deform and collapse. This is also the case for lithium batteries, one of the main reasonss of the drop in power. During this process, there are more and more lithium ions in the negative electrode. Excessive accumulation causes lithium atoms to turn into strain crystals, causing the lithium battery to swell.
