Solid-State Battery Market Size

The global solid-state battery market size was valued at USD 1,497.70 million in 2023. It is expected to reach USD 24,476.76 million by 2032, registering a CAGR of 36.4% during the forecast period (2024–2032).

Solid-state batteries utilize solid electrodes and a solid electrolyte instead of liquid or polymer gel electrolytes in lithium-ion batteries. A solid-state battery has a high energy density than a Li-ion battery based on a liquid electrolyte solution. There is no need for safety components because there is no danger of explosion or fire, saving space. A solid-state battery can elevate energy density per unit area because only a few batteries are required. As a result, a solid-state battery is ideal for constructing a high-capacity EV battery system that includes a module and a pack.

Growth Factors

Growing research and development activities

Compared to lithium-ion batteries, solid-state batteries have high energy density, solid structure, and stability, and are safe to use. Although they have a few limitations, such as low ionic conductivity, high reactivity, and higher cost, their demand is burgeoning rapidly. To overcome such limitations, different solid-state electrolytes are made with various materials.

Although solid polymer and inorganic electrolytes are excellent for all-solid-state batteries, they have limitations such as low ionic conductivity and poor mechanical properties, which have been overcome by the discovery of Composite Solid Electrolytes (CSEs) that contain active or passive inorganic fillers and polymer matrices. Many firms are working on developing solid-state batteries, including Robert Bosch, Quantum Scape, Planar Energy Devices, Toyota Motor, etc. Such an initiative by significant players is propelling the adoption of solid-state batteries in various verticals.

Longer shelf-life of solid-state batteries over traditional batteries

Today's lithium-ion batteries fall short of what's needed. In addition, they are too heavy and costly and take a long time to charge. On the other hand, solid-state has the potential to stay for a long run, has high energy density, and fast charging, which further makes EVs cheaper. 

Silicon has ten times the energy density of graphite, making it a highly desirable anode material. However, as a battery charges and discharges, the silicon anodes expand and degrade rapidly, especially in Li-ion cells that use liquid electrolysis.

Solid-state batteries promise to be safer, less expensive, and last longer. Sodium-ion chemistries are especially promising because sodium is inexpensive and abundant, unlike lithium, which is mined at a high environmental cost. The goal is to generate batteries that can be used in large-scale grid energy storage applications to store power generated by renewable energy sources to reduce peak demand.

A solid state is the potential to address several issues listed on the current Li-ion batteries. The application of an alkali-metal anode, which is impossible with a conventional battery, burgeons the energy density of the c cathode and delivers a long life. The solid-state electrolyte is assumed to be nonflammable or self-ignitable. The non-combustible property of a solid-state battery reduces the risk of thermal runaway and allows tighter cell packaging. This helps to improve design flexibility and volumetric density. 

Restraining Factors

High manufacturing cost of solid-state batteries

High manufacturing costs are the primary constraint in the market. The development of solid-state batteries necessitates significant investments in R&D as well as the establishment of manufacturing facilities. To produce solid-state batteries, manufacturing facilities must include sophisticated machinery and cutting-edge technologies.

It is challenging to design a stable solid electrolyte, a good conductor of ions, and chemically inert when manufacturing solid-state batteries. They are thus considered to be more expensive to manufacture than lithium-ion batteries. Furthermore, the process is complicated by the risk of cracking due to the brittleness of the electrolytes.

Solid-state batteries are now roughly eight times more expensive than Li-ion batteries. Because the technologies used to create these batteries differ from those used to develop conventional batteries, solid-state battery manufacturers may require separate production line setups. Furthermore, the machinery and technologies needed to develop solid-state batteries require large investments. This is a significant impediment, particularly for newcomers to the market.

Market Opportunities

Growing demand for electric vehicles

The application of solid-state batteries in electric vehicles is one of the significant growth opportunities for the solid-state battery market. Policy changes in countries such as the United States, the United Kingdom, Germany, China, and Japan increase the global demand for electric vehicles.

Electric vehicles have become more common in mobility in the automotive industry. With concerns about oil depletion and the effects of climate change caused by greenhouse gas emissions from tailpipes, the world is looking for alternatives. Due to features such as zero tailpipe emissions, higher power efficiencies, and lower costs compared to gasoline counterparts, EVs can be a viable alternative to petroleum-powered vehicles.

In addition, the Government and cities have introduced regulations and incentives to accelerate the shift towards sustainable mobility. CO2 emissions protocols in the European Union played a critical role in encouraging the sale of electric vehicles. The European Union plans to sell 100% emission-free cars by 2035 to support the net-zero emission initiative. Thus, driving the trend toward electric mobility, which uses brushless DC motors.

Electric car sales reached 3 million in 2021, up 40% from 2019. Although the market was slightly affected by the global pandemic, EV sales bounced back in the first quarter of 2021. According to EV Volumes, all regions and most countries witnessed a substantial increase in EV sales, with a growth rate 3 to 8 times higher than for the total light vehicle markets. The countries like Norway, Netherland, Sweden, China, Germany, France, and the UK have experienced a significant rise in plugin vehicle market share from 2019 to 2020.
