Li-ion batteries are developed from lithium batteries. Japan's Sony company invented the carbon material as the negative electrode, with lithium-containing compounds as the positive electrode, in the process of charging and discharging, there is no metal lithium, only lithium-ion, this is the lithium-ion battery. There is no specific inventor.

Anyone can develop their own materials. There are many kinds of materials for positive and negative electrodes, such as lithium manganese oxide, lithium iron batteries, ternary material batteries, etc., each company has developed different materials according to its own research and development experience, and its materials, dosages and other formulas are confidential, which are trade secrets, and it is impossible to apply for a patent, because patents need to disclose all information.

Of course, patents will be generated in the actual research and development of batteries, such as your battery with a special structure, or treatment method, to achieve a special purpose, you can apply for a patent, generally for utility model patents, rarely invention patents!

There is no specific reference to patents, so it is basically equivalent to the Liunx operating system. It is open source.

In 1800, the first battery in history – a power supply device that provided a steady and continuous current – the voltaic stack was born.

Stanley Whittingham of Exxon Oil Company in the United States invented the lithium battery. He used titanium sulfide as the cathode material and lithium metal as the anode material to make the first lithium-ion battery.

Akira Yoshino, John Goodenough, and Stanley Whittingham.

Yoshino: Lithium-ion batteries used in smartphones and electric vehicles.

The most influential is the person who has really changed the world, and his contribution in the field of lithium batteries is "revolutionary" than Canon Tokki's contribution in the field of OLED bibs

John Goodenough: Lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate.

Inventor of cathode materials (relay).

John Goodenough: Titanium sulfide is used as the cathode material, lithium metal.

As an anode material, the first lithium battery was made (initially).

Sony's cobalt-based lithium battery and NEC are manganese-based lithium-ion batteries, both of which were born in the early 90s and were successfully commercialized.

Lithium-ion battery products were invented by Sony in the early 90s of the last century.

Lithium batteries have been invented as early as the forties and fifties of the last century, but because they use elemental alkali metal lithium as the anode material, the safety is poor, and it cannot be charged, so it is not very widely used.

At the end of the eighties of the last century, Japanese scientists discovered that the use of lithium-ion compounds as battery cathodes not only greatly improves the safety of the battery, but also can be charged, thus inventing the lithium-ion battery.

Abstract: the present invention relates to a lithium battery protection circuit, an object is to provide a lithium battery protection circuit that adopts low-voltage process manufacturing, can be applied to various charging voltage values, and its technical scheme is: a lithium battery protection circuit is composed of an overcharge control tube, an overdischarge control tube and a protection IC, the overcharge control tube and the overdischarge control tube are monitored and controlled by the protection IC, and the protection IC is a CMOS integrated circuit block, which comprises an overcharge protection circuit, Over-discharge protection circuit and over-current protection circuit, in the protection IC, a clamping circuit is arranged between the gate of the output negative electrode V- and the MOS transistor connected with the output negative electrode V-, and when the voltage of the output negative electrode V- changes in a large range, the clamping circuit bears most of the negative voltage, so that the gate bearing voltage of the MOS transistor is limited to the range, and does not affect the functions of the overcharge protection circuit, the over-discharge protection circuit and the overcurrent protection circuit.

There are many, many more of them, and you have to give me a specific plan to find out if there is registration. Thank you!

The flow chart of the application and examination of invention, utility model and design patents is as follows:

Volt, also called Volta. Inventor of the battery Volta (1745-1827). Born in 1745 and died in 1827, Volta was a professor of physics at the University of Pavia.

He invented the starter plate used to generate static electricity and discovered and isolated methane gas. In 1794 he experimentally discovered that metals could produce electric current. In 1800 the first battery of voltaic was introduced.

The following year, after Napoleon saw his battery show in Paris, he made him count. In honor of Volta, the unit of electromotive force "Volt" was named after his surname.
