Lithium ion battery overview
Continuous discharge time – the sum of the time that the tycorun battery discharges before the specified termination voltage under a certain external load. Termination Voltage – The specified minimum discharge voltage or maximum charge voltage when a battery is discharged or charged. Residual Capacity – The residual capacity of the battery that can be …
The birth of everything has a certain background. The production of lithium-ion batteries is also inseparable from this. The oil crisis in the 1960s and 1970s forced people to look for new alternative energy sources. As metal lithium is the lightest of all metals, has the lowest redox potential, and has the highest mass energy …
Diaphragm is an important part of lithium-ion battery. Its performance determines the internal resistance of the battery’s interface structure, which directly affects the battery’s capacity, cycle performance and other key characteristics. Excellent performance of the diaphragm is important for improving the overall performance of the battery. effect. Lithium-ion battery separator materials are mainly porous polyolefins, …

Lithium-ion batteries have been widely used in mobile phones, notebook computers and other small portable electronic devices. Because they use lithium-ion batteries with small capacity (below 1~2A.h), most of them use single-cell batteries, and their batteries are safe. The problem is not too prominent. Even so, cell phone battery explosions and fire incidents occasionally occur. …

Lithium ion battery is a new type of high-energy battery developed in the 20th century. At the end of the 1960s, Broad head of Bell Labs and others first began to study the “electrochemical intercalation reaction”. In the early 1970s, Exxon Company designed a secondary battery with lithium metal as the negative electrode and TiS2 …
