Battery Family Evolution History
In the distant ancient times, people were in awe of thunder and lightning. Billions of thunderstorms occur every year over the earth. It can knock people down, split tall trees in half, and even cause a raging fire. Westerners regard thunder and lightning as "God's wrath", while Easterners refer to it as "Thunder God". For a long time, thunder and lightning have been a kind of terrible unknown in people's hearts.
Until more than 300 years ago, Benjamin Franklin's scientists began to use lightning kites to capture lightning. This has officially opened people's awareness of lightning and electricity. Since then, people have begun to consider how to capture lightning. Electricity storage.
"Battery Family Birth History"
In 1799, Italian physicist Voda made a detailed study of the theory of "neuronal current" proposed by Galvani, an anatomy professor at the University of Polona, Italy 19 years ago. Paper and zinc sheets were stacked one after the other, creating the earliest Volta stack that achieved continuous current.
In 1801, he demonstrated the Vodafone reactor for Napoleon I. Napoleon awarded him a gold medal and named him Earl.
In 1803, the German chemist Ter made a battery.
In 1836, British chemist J.F. Danielle created the first classical primary battery.
In 1859, French physicist Planter produced the first practical lead-acid battery.
In 1865, French chemist Le Croncher created the first dry cell.
In 1881, the French scientist Camille Alphonse Faure improved the design of the battery. The first tricycle powered by lead-acid batteries was born. The vehicle weighed 160 kg, but the speed was only 12 km / h .
In 1884, British inventor and industrialist Thomas Parker, the British inventor and industrialist, built the first practical electric car in London with his own specially designed high-capacity rechargeable battery.
In 1888, chemist Cassnier improved Le Crancher's battery.
In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis.
In 1970, Exxon's M.S. Whittingham used titanium sulfide as the cathode material and lithium metal as the anode material to make the first lithium battery, known as the founder of lithium batteries.
In 1991, Sony Corporation and Asahi Kasei Corporation successfully released the first commercial lithium-ion battery.
`` Lithium Family Becomes Family ''
At present, the current owner of the lithium battery family, the ternary lithium battery and the head mother lithium iron phosphate battery are superior. They lead the entire family with their excellent bloodlines and outstanding talents. They are the two most popular mainstream power batteries in the current market. Several years have led the whole family to flourish.
Among them, the ternary lithium battery is also called ternary polymer lithium battery, which is a lithium battery with nickel-cobalt lithium manganate or lithium nickel-cobalt aluminate as the positive electrode material. It is a rising star battery in recent years. Its body Small and thin, but the strongest and most popular, especially with the commercial vehicle family, with the support of the public car family, was successfully elected as the owner of the lithium battery family. Although he has strong ability and good physical strength, he has a hot temper and often “explodes”. The car families love and hate it. Among them, Tesla, the most famous "black horse family" in the car family, has always favored him. Although the battery owner has a grumpy temper, he still can't stop his worldly talent.
The full name of contemporary primary lithium iron phosphate batteries is lithium iron phosphate · lithium ion · batteries. Lithium iron phosphate batteries refer to lithium ion batteries using lithium iron phosphate as a positive electrode material and graphite as a negative electrode material. The head mother and mother are strong and physically strong, but the spleen is warm, healthy and cheerful. Although the ability is slightly inferior to the owner's ternary lithium battery, it is also loved by the BYD family of car giants.
The owner of the ternary lithium battery and the main mother lithium iron phosphate battery can be described as a rage, each leading the way, all show their talents in their respective fields, without distinction. When Nai transited, the homeowner and mother-in-law were old, their abilities were gradually tapped out, and their potential was exhausted, and more and more family stars began to emerge to fight for homeownership. In the future, it will be the world of young people.
Each branch is unwilling to show weakness, and join forces with the outside world to build a car, trying to compete for the next homeowner.
Bet on that power battery technology route is not a distress within the lithium battery family, but a common problem for all external supporters of power batteries.
The highest external voice is the "solid battery" of Shenlong, which is not seen at the end. It is a goddess of science and technology. It is said to be a battery using solid electrodes and solid electrolyte. Solid-state batteries generally have lower power density and higher energy density. Because of its high power and weight, solid-state batteries are ideal battery mates for many talents in the electric vehicle family. But it is like the moon in the flower in the mirror, which has always been heard only by his voice. There are many "semi-solid-state batteries" on the market that have envied the reputation of solid-state batteries and imitated them. They have "swept the market" under the name of "solid-state batteries." According to the largest force in the battery family, the Ningde era family from the mysterious east said that solid-state batteries from its family will officially appear in the 2030 election campaign.
Similar to its situation, there is also graphene batteries. Because of their unique characteristics, graphene is called a "magic material", and scientists have even predicted that it will "revolutionize the 21st century."
Recently, the battery family has killed a "black horse"-"cobalt-free battery", which has been obscured. Recently, it has been watched and vigorously cultivated by the top car-making forces Tesla family. It was reported online that it had a blood relationship with the head mother and mother, but was subsequently denied by Tesla. So far, the life of cobalt-free batteries is a mystery, but it is undeniable that it is also a member of the battery family and is likely to become the commander-in-chief of battery owner candidates in recent years.
Of course, there is also a hydrogen fuel cell that is extremely dazzling. The hydrogen fuel cell has a high energy density and obvious long-life advantages. It can be used in large load scenarios, such as large ocean-going ships and heavy long-distance vehicles. These application scenarios. Ultra-long battery life and environmental protection have become the most shining labels for hydrogen fuel cells. Governments around the world are also increasing their policy support and are the most promising batteries in the future.
