What is li ion technology

Using different chemicals and materials for these affects the properties of the battery — how much energy it can store and output, how much power it can provide or the number of times it can be discharged and recharged also called cycling capacity.

Battery companies are constantly experimenting to find chemistries that are cheaper, denser, lighter and more powerful. We spoke to Saft Research Director Patrick Bernard, who explained three new battery technologies with transformative potential. In lithium-ion Li-ion batteries, energy storage and release is provided by the movement of lithium ions from the positive to the negative electrode back and forth via the electrolyte.

In this technology, the positive electrode acts as the initial lithium source and the negative electrode as the host for lithium. Several chemistries are gathered under the name of Li-ion batteries, as the result of decades of selection and optimization close to perfection of positive and negative active materials. Lithiated metal oxides or phosphates are the most common material used as present positive materials. With actual materials and cell designs, Li-ion technology is expected to reach an energy limit in the next coming years.

Nevertheless, very recent discoveries of new families of disruptive active materials should unlock present limits. These innovative compounds can store more lithium in positive and negative electrodes and will allow for the first time to combine energy and power. In addition, with these new compounds, the scarcity and criticality of raw materials are also taken into account. Today, among all the state-of-the-art storage technologies, Li-ion battery technology allows the highest level of energy density.

New generation of advanced Li-ion batteries is expected to be deployed before the first generation of solid-state batteries. In Li-ion batteries, the lithium ions are stored in active materials acting as stable host structures during charge and discharge.

It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society. Despite being over four decades old, interest in Li-ion technology and its use in electronics applications continues to grow.

Recent estimations say that the market will grow at a compound annual growth rate CAGR of In the early s, Whittingham, who at the time was a chemist at Exxon, started exploring the idea of a new battery that could recharge on its own in a short amount of time: a Li-ion battery.

Then in the s, Goodenough, who was an engineering professor at the University of Texas at Austin at the time, had a different idea. He experimented using lithium cobalt oxide as the cathode instead of titanium disulfide. Finally, five years later, Yoshino, who was working at Asahi Kasei Corporation, developed the use of graphite for the anode. Initially, petroleum coke was used, but graphite was found to be a far better material.
