Which elements for lithium batteries?

Lithium battery element

The abbreviation for lithium battery mainly refers to a type of battery in which lithium element used as a main active material in an electrode material. From this definition, a lithium battery refers to a type of battery, including a lithium primary battery (primary battery) and a lithium secondary battery.

Lithium batteries have the advantages of being light and durable (compared to the lead storage batteries on electric vehicles), and the environmental pollution is relatively small.

A lithium battery is a type of battery in which graphite used as a negative electrode material and a nonaqueous electrolyte solution is used. The inventor of the lithium battery is Edison.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not used for a long time. With the development of microelectronics technology at the end of the twentieth century, the number of miniaturized devices has increased, and high requirements have placed on power supplies. Lithium batteries have entered a large-scale practical stage.

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

Lithium batteries can roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation lithium-metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only a few companies in the country are producing such lithium metal batteries.

Lithium-iron phosphate batteries do not contain cobalt lithium-ion batteries are one of the current mainstream power batteries. Not all power batteries contain cobalt, and not all lithium-ion batteries contain cobalt, such as lithium manganese oxide. The battery, lithium nickelate battery, and lithium-iron phosphate battery do not contain cobalt. The definition of Baidu Encyclopedia can -used to distinguish the power battery from the digital battery. New energy vehicles can also use hydrogen as energy. Use a power battery.

Lithium cobaltate, lithium manganate, lithium iron phosphate, lithium nickel cobalt manganese oxide, etc. all become lithium batteries because they all contain lithium ions; normally, lithium iron phosphate is cobalt-free, unless it is specially demanded. Miscellaneous; power battery includes lithium battery, nickel-hydrogen battery, lead-acid battery, etc., mainly used in the power of the car is called the power battery; lithium cobalt oxide is lithium cobalt oxide, mainly used in the consumption of mobile phones Battery; the last question is like asking the light bulbs in the room to be called lights.

A lithium metal battery is generally a battery using manganese dioxide as a positive electrode material, metallic lithium or an alloy metal thereof as a negative electrode material, and a nonaqueous electrolyte solution. Discharge reaction: Li+MnO2=LiMnO2

A lithium ion battery is generally a battery using a lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, and a nonaqueous electrolyte.

The reaction that occurs on the charged positive electrode is

LiCoO2==Li(1-x) CoO2+XLi++Xe-(electron)

The reaction occurring on the charging negative electrode is

6C+XLi++Xe-=LixC6

Rechargeable battery total reaction: LiCoO2+6C=Li(1-x) CoO2+LixC6

Positive

Carbon anode material

The negative electrode materials that have been practically used for lithium ion batteries -basically carbon materials such as artificial graphite, natural graphite, mesocarbon microbeads, petroleum coke, carbon fiber, pyrolysis resin carbon, and the like.

Tin-based anode material

Tin-based anode materials can -classified into tin oxides and tin-based composite oxides. Oxide refers to oxides of various valence metal tins. There are no commercial products.

Nitride

There are also no commercial products.

Alloy

Including tin-based alloys, silicon-based alloys, bismuth-based alloys, aluminum-based alloys, bismuth-based alloys, magnesium-based alloys and other alloys, there are no commercial products.

Nanoscale

Carbon nanotubes, nano-alloy materials.

Nano oxide

According to the latest development of market development of lithium battery new energy industry in 2009, many companies have begun to use nano titanium oxide and nano silicon oxide to add to traditional graphite, tin oxide and carbon nanotubes, which greatly improve the charging of lithium batteries, amount and the number of charge and discharge.
