The development of new energy vehicles is unstoppable. Existing lithium batteries are only intermediate products

After ten years of development, the new energy automobile industry has been unstoppable in the world, and it will be intelligently promoted in the future, and there is huge space for development. At present, there are three main consumption areas of new energy vehicles in the world, namely Europe, China and the United States. Due to the implementation of the strictest carbon emission standards in Europe and the promotion of heavy subsidy policies, the new energy market has developed rapidly, and the penetration rate of some Nordic countries has reached 80%. Has entered the stage of consumption-driven growth, the United States after President Biden came to power to promote new energy, launched a proposal to provide up to $30 billion in subsidies, up to $12,500 per bike, after the adoption of the policy, the United States new energy vehicle market will usher in a big outbreak, is expected to take over China, Europe's growth stick, driving the global new energy market to continue to advance.

However, it is undeniable that the existing liquid lithium-ion battery has more shortcomings, its energy density is low, whether it is really environmentally friendly remains to be seen, and it is easy to leak, heat dissipation is not good, because it can not effectively inhibit the growth of lithium dendritic batteries are easy to explode, very unsafe, and the battery life is short, so many car companies think that it is only an intermediate product.

Solid-state batteries have many advantages and are expected to become the ultimate form of batteries

Solid state battery is the use of solid electrolyte battery, in 1980 the father of lithium battery American scientist John Goodenough put forward the concept of solid state battery, is considered to be the ultimate form of battery, compared with liquid electrolyte, solid electrolyte has more advantages, first of all, battery safety has been greatly improved, because solid electrolyte mechanical strength is high, and will not form leakage. It will not be affected by the penetration of lithium dendrites to make the battery short circuit, which greatly improves the safety of the battery. At the same time, the voltage and temperature can use lithium metal negative electrode to greatly improve the energy density of the battery, perfectly solve the current range anxiety problem of new energy vehicles, and the battery life can exceed 1000 kilometers. In addition, the solid state battery does not need electrohydraulic and separator, which greatly simplifies the battery structure. Promoting the battery to lightweight is the future direction of lithium batteries.
