It is important to note that the exact release dates for solid-state battery electric vehicles may vary depending on technological advances, testing and long-term validation of the technology. In general, it is estimated that the first electric vehicles with solid-state batteries will be available on the market around 2025.

In order to better understand the operation of solid state batteries, the Nova Rent a Car Iasi airport company will first explain how lithium-ion batteries work. Lithium-ion batteries are the most common types of batteries used today in electric cars and a wide range of portable electronic devices. They work by transferring lithium ions between a cathode and an anode during the charging and discharging process. Here's how lithium-ion batteries work:

1. Cathode: The cathode is one of the important components of a lithium-ion battery. Typically, the cathode is made of a metal oxide, such as cobalt oxide, nickel oxide, or lithium manganate. The cathode is positively charged and is where the reduction reaction takes place during discharge.
2. Anode: The anode is the other key component of the lithium-ion battery and is usually made of graphite. The anode is negatively charged and is where the oxidation reaction occurs during discharge. During the discharge process, lithium ions are released from the anode and move to the cathode through the electrolyte.
3. Electrolyte: The electrolyte is a medium through which lithium ions can move between the cathode and the anode during the charging and discharging process. In lithium-ion batteries, the electrolyte is usually an organic liquid, such as an organic solvent and lithium salts dissolved in it. The electrolyte allows ionic movement, thus allowing the transfer of lithium ions between the cathode and the anode.
4. The Separator: The separator is a thin, porous membrane placed between the cathode and the anode to prevent short circuits and direct contact between the two electrodes. The separator allows the passage of lithium ions during discharge and charge, but prevents direct contact between the two components to avoid unwanted reactions.

During discharge, lithium ions are released from the anode and move through the electrolyte to the cathode. At the same time, electrons are released from the anode and circulate through the external circuit, generating electric current. At the end of the discharge, most of the lithium ions are in the cathode. During the charging process, the electric current applied to the battery causes the transfer of lithium ions from the cathode back to the anode. This is the reverse reaction of the discharge and allows the battery to charge.

Solid-state batteries represent a new battery technology that replaces the liquid electrolyte in traditional batteries with a solid electrolyte, and the Nova Rent a Car Airport Iasi agency describes to you in the lines below how solid-state batteries work and how they work:

1. Solid electrolyte: In solid-state batteries, the electrolyte is replaced by a solid material, usually a solid polymer or ceramic. This solid electrolyte acts as an ion conductor, allowing lithium ions to move between the cathode and the anode.
2. Cathode: The cathode in solid-state batteries can be constructed from materials similar to those used in traditional lithium-ion batteries, such as cobalt oxide or nickel oxide. The cathode is positively charged and receives lithium ions during the charging process.
3. Anode: The anode in solid-state batteries can be made of various materials, including alkali metals, silicon, graphite, or other composite materials. The anode is negatively charged and releases lithium ions during the discharge process.
4. Solid-electrolyte interface: In solid-state batteries, there is a solid-electrolyte interface between the solid electrolyte and the cathode and anode. This interface facilitates ion transfer between the two components and allows the battery to function.
5. The separator: Similar to lithium-ion batteries, solid-state batteries use a separator to prevent short circuits and direct contact between the cathode and anode. The separator in solid-state batteries can be a porous solid membrane or a composite material that allows the passage of lithium ions and prevents direct contact.

During discharge, lithium ions are released from the anode and move through the solid electrolyte to the cathode. At the same time, electrons are released from the anode and circulate through the external circuit, generating electric current. At the end of the discharge, most of the lithium ions are in the cathode. During the charging process, the electric current applied to the battery causes the transfer of lithium ions from the cathode back to the anode through the solid electrolyte. This process allows energy to be stored in the battery and prepares the battery for a new discharge.

Solid state batteries have a number of significant advantages over traditional electrolytic liquid batteries. Here are some of those advantages:

• Higher energy density: Solid state batteries offer higher energy density, which means they can store more energy in a smaller volume. This leads to a longer range of electric vehicles and a longer operating life of portable electronic devices.
• Reduced charging time: Solid state battery technology enables higher charging rates compared to traditional batteries. This means that solid-state batteries can be charged much faster, reducing waiting times at charging stations and increasing user convenience.
• Improved safety: Solid-state batteries eliminate flammable liquid from traditional batteries, reducing the risk of leaks and fires. The solid materials used in the construction of these batteries are more stable and less susceptible to damage or defects that can lead to dangerous situations.
• Improved Durability: Due to their solid construction, solid state batteries are more resistant to damage and degradation over time. They can withstand more charge-discharge cycles without losing performance, making them a durable and cost-effective option in the long run.
• Extended operating temperatures: Solid state batteries have better thermal resistance than traditional batteries. They can operate in a wider range of temperatures, from extremes of cold to extremes of heat, without losing performance.

These advantages of solid-state batteries make them attractive for a wide range of applications, from electric vehicles to portable electronic devices and energy storage systems. Although solid-state battery technology is still in the development and testing stages, these promising advantages suggest a brighter future for electric mobility and energy storage.

Solid-state batteries are a promising technology that has the potential to revolutionize the automotive industry and accelerate the adoption of electric vehicles. These batteries offer significant advantages such as higher energy density, reduced charging time, improved safety and increased durability. The market launch of electric cars equipped with solid-state batteries, according to the information presented above by the Nova Rent a Car Iasi Airport office, could bring significant benefits to users, contributing to increasing vehicle autonomy, reducing charging time and improving the user experience of electric vehicles. However, the development and commercialization of these batteries still involve some technological and cost challenges that must be addressed to ensure successful implementation. With continued support from automakers and investment in research and development, solid-state battery technology is expected to become a reality in the near future, opening new and promising doors for electric mobility.
