How many NMC lithium-ion battery patents are there?
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.
What is a lithium-ion battery?
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.
Do lithium ion batteries have protection circuitry?
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.
Does lithium titanate affect battery performance?
The use of lithium titanate in a battery is believed to reduce the likelihood of lithium plating during charging. Lithium plating is a phenomenon that can negatively impact the performance of lithium-ion batteries.
Can a lithium ion battery be fully discharged?
A lithium-ion battery such as that described herein can be fully discharged while the materials for both electrodes, including their corresponding current collectors, remain stable (e.g., corrosion of the current collectors and/or the decomposition of active material may be avoided, etc.).
Can lithium ion batteries be plated?
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.
