Lithium ion batteries can be affected by lithium plating, which can lead to a loss in performance. However, cells with lithium titanate negative electrodes may be charged at rates that exceed those with carbon negative electrodes, being free from the risk of lithium plating.
A lithium-ion battery is a type of rechargeable battery. It includes a positive electrode with a positive current collector, a first active material, and a second active material. The battery also includes a negative electrode with a negative current collector and a third active material, where the third active material is a lithium titanate material.
Currently, more than 4,000 patents have been granted, mainly in Japan and China, and more than 3,600 patent applications are pending, mainly in the USA and China. More than 590 patent applicants can be found on the NMC Lithium-ion Battery patent landscape.
Toyota Group holds the most extensive patent portfolio in Li-ion battery technology with 3,840 IP assets, within the past seven years.
Conventional lithium-ion batteries may include protection circuitry to prevent damage in the event of a low voltage condition. These batteries may be utilized in devices that include protection circuitry, which reduces the current drain from the battery by disconnecting it when necessary.
Although their charge densities tend to be lower than lithium-based batteries, sodium-ion batteries are well suited to use in static storage and low-cost electric vehicles, such as e-bikes, and may soon replace lithium as a preferred battery chemistry for these applications.
