Traditional lithium-ion batteries continue to improve, but they have limitations that persist and this is partly due to their structure. A lithium-ion battery consists of two electrodes – one positive and one negative – sandwiched around an organic (carbonaceous) liquid electrolyte. Once the battery is charged and discharged, electrically charged particles (or ions) of lithium pass from one electrode to the other through the liquid electrolyte.
One problem with this design is that at certain voltages and temperatures, the liquid electrolyte can become volatile and catch fire; and another is that lithium-ion batteries are not well suited (in their current form factor) for use in electric vehicles (EVs).
Large, heavy battery packs take up space and increase the overall weight of a vehicle, which reduces its fuel efficiency.
Researchers are therefore changing the key features of the lithium-ion battery to make a very solid or “solid-state” version. In this they replace the liquid electrolyte in the middle with a thin and solid electrolyte, which remains stable over a wide range of voltages and temperatures.
With the solid electrolyte they use a high capacity positive electrode and a high capacity lithium metal negative electrode which is far thinner than the usual layer of porous carbon. These changes make it possible to significantly shrink the overall battery while maintaining its energy storage capacity, thereby achieving a higher energy density. These features – enhanced safety and greater energy density – are probably two of the most-often-toouted benefits of a potential solid-state battery.
EV batteries are extremely stressful during their long life. The two leading stressors are fast loading and extreme temperatures. The capacity of the battery to accept charge varies considerably with temperature.
Traditional battery management systems (BMS) do not adjust the degree and rate of charge based on health. Temperature gradients across the pack cause uneven deterioration, especially during fast charging. Therefore, any of the hundreds of cells in the battery pack may develop an internal short and ignite the entire pack.
There are two ways to improve battery life for safer EVs.
1) Develop more secure cell chemistry: Important research and investment pursue new technologies. An intelligent approach would be required to monitor the degree and rate of charge in real time based on detailed diagnosis of the cells in the pack.
2) Deploy Software Intelligence: This can be done to predict the rare presence of defects and ensure that the batteries work safely. The precautionary security software stack is essential to identify the rare battery defect before it leads to a fire.
We believe that intelligent software with predictive capabilities is essential to provide additional security measures. In addition, the technology is available today and can provide the required security with significantly reduced costs.
Errors can occur suddenly and violently, with the potential for serious injury, product loss, and reputation loss. So it is crucial to invest in software intelligence to monitor battery diagnostics and predict the presence of defects, and be prepared to remove dangerous batteries from circulation before they lead to catastrophic incidents.

How long can a lithium-ion battery last without charging?
Sometimes it’s okay to forget after a few days. Basically, after a month or half a month of building up, the problem is not big. But in this case, if you leave it for three or four months without charging it, it will almost fall off.
How long can a lithium battery stay dead? The minimum life most lithium-ion battery manufacturers expect is about 5 years or at least 2,000 charge cycles. However, if well maintained and used in proper conditions, lithium-ion batteries can last as long as 3,000 cycles.

How long can a lithium-ion battery last without charging?
Use a two to three year life expectancy for batteries that do not run through complete charge cycles. Rechargeable lithium-ion batteries have a limited life and gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible.
What happens if you don’t charge a lithium battery for a long time?
If the new product is not charged for a long time, the battery will fail. When used under normal conditions, it should be charged while the battery is running. Otherwise, the battery will fail.
How long can a lithium battery last without charging?
Under normal circumstances, it is charged. Sometimes it’s okay to forget after a few days. Basically, after a month or half a month of building up, the problem is not big. But in this case, if you leave it for three or four months without charging it, it will almost fall off.

And the batteries degrade even when you are not using them. According to battery testing company Cadex Electronics, a fully charged lithium-ion battery will lose about 20 percent of its capacity after a year of typical storage.
Should lithium batteries be fully discharged?
Unlike other batteries that need to be charged during their storage time, lithium batteries perform better at 40% -50% DOD (depth of discharge). Pro Tip: After every 30 charges, allow your lithium-based battery to fully discharge before recharging. This helps to avoid a condition called digital memory.
How do you store lithium ion batteries when not in use?
Store batteries in a mild, dry climate. Batteries should be stored away from sunlight, heat and moisture. Keep the storage area ventilated and dry, and maintain a relatively constant temperature. The ideal battery storage temperature is around 59 ‰, but most room temperatures are sufficient.

Shelf life is 3-5 years. Like the other non-rechargeable, lithium non-rechargeable batteries have no cycle life. Our experience with them is that lithium non-rechargeable batteries last 10-12 years. Factors that determine the shelf life are the quality of the manufacturing process, the chemical composition, etc.
