What is so good about the development of lithium batteries? Why are we all scrambling to be first in the enterprise
The working principle of a lithium battery is to charge and discharge through the positive and negative electrodes nmp solvent. It may be a bit complicated to understand, but you need to pay attention to the different elements represented by the positive and negative electrodes, for example: the main positive component is LICO02, the main negative C, and then by calculation, produce different reactions.
Maybe you have to ask, there are so many types of batteries on the market, why do you keep talking about lithium batteries? Because the demand for lithium batteries is large, and it is bound to dominate the market in the past few years. First of all, there are many usage scenarios for lithium batteries. Most of the mobile phones, computers, and electronic devices we start using are used for lithium batteries. Then we all know that in the past two years, more and more new energy electric vehicles have appeared around.
Therefore, the biggest impetus to promote the growth of lithium-ion batteries will definitely come from electric vehicles nmp. The data shows that by 2017, the demand for lithium-ion batteries of 20.71 million kWh and a market share of 22% surpassed that of smartphones and became the lithium-ion battery market. By 2020, it will occupy a 31.4% share of the entire consumer electronics market, and the total demand will exceed 62 million kWh.
So, what is so good about lithium batteries that so many companies and individuals are vying to seize them? Here are some advantages of lithium batteries:
High voltage, the nominal voltage of lithium batteries reaches 3.6V-3.85V 1 methyl 2 pyrrolidone; it is 3 times that of Ni-MH batteries and 1.1 times that of lithium iron phosphate;
The energy density is high, and the lithium battery provides an energy distribution density of 250wh/kg; it is twice that of the nickel-metal hydride power battery and lithium iron phosphate;
Long cycle life, the cycle life of lithium batteries is generally 500-1000 times, and the cycle life of lithium iron phosphate batteries can reach 2000 times;
Environmental protection, no pollution, five memory effects, lithium batteries do not contain cadmium, lead, mercury and other environmental pollution elements;
The self-discharge is small, and the self-discharge rate of a fully charged lithium battery at room temperature is about 2% after being stored for one month.
It can be charged and discharged quickly, and the battery can be fully charged in 1.5 hours; the battery can be fully discharged in 6 minutes at the fastest;
The working temperature is -20 ~ 60 °C, and the low-temperature discharge point capability of the low-temperature battery can reach -40 °C.
Therefore, lithium batteries are more practical than nickel metal hydride batteries and lithium iron phosphate in terms of safety, performance, life, and environmental protection, rather than needing to be replaced after a period of time, which will undoubtedly increase the cost of use. The most important thing is fast charging. Nowadays, many electric vehicles have the problem of slow charging. They often need to queue up for charging for at least 1-2 hours, which causes headaches for many car owners and often wastes time. The lithium battery perfectly solves this problem, which is simply good news~
