CATL announces sodium ion battery technology! Can charge 80% in 15 minutes, dangerous for fuel vehicles
There are many reasons for choosing electric vehicles, but I believe that friends who choose fuel vehicles have two very important reasons: one is that fuel vehicles will not have the problem of mileage anxiety; the other is that the time cost of waiting for refueling is very low.
The world's first aluminum-ion solid-state battery is mass-produced, which is half cheaper than lithium batteries
Saturnose, an Asian battery research and development company, announced that it will publicly release independent test results of enhanced aluminum-ion batteries, and plans to launch solid-state rechargeable aluminum-ion batteries, which will be released as soon as next year. This may be the world's first mass-produced commercial-grade aluminum-ion solid-state battery, which is expected to replace the risky lithium-ion battery.
18650 lithium battery has high energy density, so most of it is used in laptop battery. In addition, because 18650 has very good stability in work, it is widely used in various electronic fields. Commonly used in high-end glare flashlights, portable power supplies, wireless data transmitters, electric heating suits, shoe materials, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.
Cylindrical lithium-ion batteries are usually represented by five digits. Counting from the left, the first and second digits are the diameter of the battery, the third and fourth digits are the height of the battery, and the fifth digit represents the cylindrical shape. There are many types of cylindrical lithium batteries, the more common ones are 10400, 14500, 16340, 18650, 21700, 26650, 32650 and so on.
Cylindrical lithium batteries usually refer to cylindrical 18560 lithium batteries, which can be divided into three material systems: lithium cobalt oxide, lithium manganate, and ternary materials. Batteries are widely used in: notebook computers, digital cameras, lighting fixtures, toy products, power tools, portable mobile energy and other fields.
Everyone is familiar with ternary batteries, and its cathode material is usually nickel-cobalt-manganese or nickel-cobalt-aluminum. What kind of battery is a quaternary battery that is one yuan more expensive than a ternary battery?
Recently, the China Automobile Manufacturers Association's November data release conference was held in Beijing. The China Automotive Power Battery Industry Innovation Alliance released monthly power battery data for October 2021. The total power battery output was 25.1GWh, an increase of 191.6% year-on-year.
Cylindrical lithium batteries are divided into different systems such as lithium iron phosphate, lithium cobalt oxide, lithium manganate, cobalt-manganese hybrid, and ternary materials. The outer shell is divided into two types: steel shell and polymer. Different material systems have different advantages.
Cylindrical lithium batteries are divided into different systems such as lithium iron phosphate, lithium cobalt oxide, lithium manganate, cobalt-manganese hybrid, and ternary materials. The outer shell is divided into two types: steel shell and polymer. Different material systems have different advantages. At present, cylindrical batteries are mainly steel cylindrical lithium iron phosphate batteries, which are characterized by high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, large discharge current, stable electrochemical performance, safe use, and wide operating temperature range. Environmental protection, widely used in solar lights, lawn lights, backup energy, power tools, toy models.
The decommissioned lithium iron phosphate batteries and the batteries after the cascade use that do not have the value of cascade use will eventually enter the dismantling and recycling stage. The difference between a lithium iron phosphate battery and a ternary material battery is that it does not contain heavy metals, and the main recovery is Li, P, and Fe. The added value of recycled products is low. Need to develop a low-cost recovery route, there are mainly two recovery methods, fire method and wet method.
