What is the biggest problem with lithium batteries

2024-04-18 15:35:31


Lithium batteries currently have a wide range of applications in our lives. Lithium batteries have this high energy density, longer cycle life and other advantages, but there are also some problems. These problems include
 
  • Safety issues
  • Cost
  • Environmental impact
  • Lifetime limitation
  • Ore Resource Issues

At the same time, lithium batteries in the life of the exhaustion, how to recycle is also a problem. Currently, the recycling rate of lithium batteries is relatively low, only about 20% worldwide, and the recycling process of lithium batteries is complicated, requiring delicate separation process and chemical treatment.

Although lithium batteries have a relatively long cycle life. But still with time and the number of times of use and performance degradation. Typically, lithium batteries can withstand hundreds to thousands of cycles and still maintain more than 80% of their initial capacity.

At the same time lithium battery has the problem of environmental impact. Although the lithium battery is conducive to the secondary use of energy, but it will consume a lot of water and land resources in the mining of the destruction of the mining process used in the chemical substances and heavy metals are controlled infiltration into the soil, causing health hazards to the surrounding residents. The manufacturing process of lithium batteries requires a large amount of electricity, which may come from fossil energy sources and generate greenhouse gases at the same time.
 
And the rapid growth of market demand for lithium batteries. Also pushed up the price of raw materials. As consumer acceptance of electric vehicles increases. This demand will continue to grow.

First of all the ore resources of lithium battery are relatively concentrated in the distribution of the earth. It mainly includes lithium, cobalt, nickel and other ores. Among them, lithium ores hit in Australia, Chile, Argentina and so on. And cobalt resources are concentrated in Congo. These geographic concentration of ores determines the instability of the supply chain. Where the price of raw materials may receive the region open. The impact of social unrest and other issues.
In order to reduce the impact of lithium batteries back to the environment, we developed the lithium battery processing equipment mainly from various types of lithium batteries back to its valuable materials, including lithium compounds, copper, aluminum and so on. The batteries are crushed into small particles by crushing and grinding. Through cyclone separation, vibrating screen separation, gravity separation and so on. Separate different materials. Maximize the recycling value of lithium batteries.

In addition to the above several problems about the life cycle of lithium batteries, another problem is the safety of lithium batteries in use, first of all, lithium batteries will appear in the use of overshooting, overdischarge, short-circuit, and heating problems. Overshoot means that the voltage of the battery exceeds the design limit, and the cathode material will release oxygen in the overshoot state, which will lead to electrolyte decomposition. Alternatively, lithium molecules can be deposited excessively, forming lithium dendrites. These lithium dendrites can penetrate the diaphragm, causing the battery to short-circuit. And prolonged over-discharge can cause the battery to fail to recharge and fail permanently.
