Li-ion batteries are a common component in many electronic devices and the research into Li-ion battery composition and safety methods is growing. This article will discuss Li-ion battery technologies and how coatings can improve Li-ion battery safety.

Li-ion Batteries Today

Li-ion battery research is an ever-expanding field in both academia and industry. Every day, new publications arise which detail a new type of electrode, a more efficient separator material, or improvements to existing electrodes through new composite additions.

The focus for most Li-ion battery research is to improve charge/discharge cycle rates and efficiencies in fast charging. These advances in battery technology have driven the development of many high quality electronic devices.

Li-ion battery safety is a high priority for many manufacturers, as these batteries are widely adopted in many applications. Nanocoatings are one way to ensure Li-ion battery safety.

Li-Ion Battery Safety Methods

Many companies are using analytical equipment to test Li-ion battery safety, but these methods only provide a quantification and realization of a potential problem, not a solution.

Nanocoating particles that are used in the slurry applied to the foil making the anode and cathode electrode in a Li-ion battery protect against aggressive degradation and overheating and ensures thermal stability of the battery.

Conformal angstrom-level precision coatings can be produced using atomic layer deposition (ALD) methods. ALD coatings not only ensure Li-ion battery safety but also enhance the existing properties of the electrodes and the battery.

Li-ion battery safety can be compromised by many external and internal conditions. Constant use of a battery can lead to high internal temperatures, especially if a battery is pushed too fast charging and high charge and discharge cycles. Battery stability under these conditions is crucial. Anode and cathode electrode corrosion is another common issue that can undermine Li-ion battery safety with the heat generated by the increasing resistance between the anode and cathode.

Nanocoatings on electrodes help to resolve both of these issues by providing a high level of thermal stability and corrosion resistance. Nanocoatings also ensure safety by pushing out the exothermic reaction temperature within the battery so as not affect the other internal components of the device.
