Lithium ion : the battery technology of choice

Li-ion battery technology uses lithium metal ions as a key component of its electrochemistry. Lithium metal ions have become a popular choice for batteries due to their high energy density, high capacity, higher power density and low weight. One notable example is lithium-ion batteries, which are used in a wide range of electric vehicles, aerospace, off grid energy storage and electronic devices. Lithium iron phosphate batteries, offer greater stability and a longer lifespan. This makes them well-suited for use in electric vehicles and large-scale energy storage systems.
Lithium batteries have four key components.

Cathode material: The material used for the positive electrode determines the voltage and capacity of the lithium-ion battery as well as being the source of the lithium ions

Anode material: When the lithium-ion battery pack is being charged, the anode material of the negative electrode is what the electric current flows through from an external circuit. It is also where Li-ions are stored.

Electrolyte: This is made up of additives, solvents, and salts. It is the conduit between the cathode and anode.

Separator: This is what separates the anode and cathode materials.

Cathode material:

The material used for the positive electrode determines the voltage and capacity of the lithium-ion battery as well as being the source of the lithium ions such as LFP and LFMP

Anode material:

When the lithium-ion battery pack is being charged, the anode material of the negative electrode is what the electric current flows through from an external circuit. It is also where Li-ions are stored

Electrolyte:

This is made up of additives, solvents, and salts. It is the conduit between the cathode and anode and transports positively charged ions between the cathode and anode terminals

Separator:

A separator is a permeable membrane placed between anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits and allow the transport of ionic charge carriers


There are other battery technologies which are underdevelopment and can take a decade to challenge the current performance and advantages of Lithium ion. In overall cathode decides the capacity, discharge rate, power density and energy density of Lithium ion battery cells and due to its vital role in battery performance, Integrals Power is developing improved cathode materials which can add significant value to the current battery ecosystem.
