The development of lithium-ion battery technology to date is the result of a concerted effort on basic solid-state chemistry of materials for nearly half a century now. Discovery of new materials and a deepening of our fundamental understanding of their structure-composition-property-performance relat...
The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the Li-ion battery cell. The anode is usually made out of porous lithiated graphite. The electrolyte can be liquid, polymer, or solid. The separator is porous to enable the transport of l...

A lithium ion battery cell typically has a positive electrode, a negative electrode, a separator, and an electrolyte containing lithium salt (e.g., LiPF6 or LiTFSI) in ether (a class of organic molecules that includes diethyl carbonate (DEC) and ethylene carbonate (EC)). The electrolyte is...
Cell balancing: In multi-cell battery packs, like the ones in EVs, individual cells might have slightly different capacities or voltages. During rest periods, when the battery is not being actively balanced through charging or discharging, heat can exacerbate imbalances between cells, potentially affe...
Lithium Ion Battery Analysis Origin of batteries Electrochemical fuel cells are composed of three components: a negatively charged cathode, a positively charged anode and an electrolyte that creates a chemical reaction which moves electrons in a circuit. Eventually the chemistry in the fuel cell ...

Lithium-ion batteries are very popular for energy storage - learn about the several different variations of lithium-ion chemistry.
The most crucial components in the LIBs are the electrodes (anode and cathode) and electrolytes which determines the storage capacity and the cell potential of the battery respectively, the cell potential is limited by the electrochemical window of the electrolyte used in the battery. Electrolytes ma...
