Guangzhou MeritSun Power Co.,Ltd
MeritSun’s vision is to make Solar ESS Lifepo4 battery accessible to the household people all around the world.
In the field of energy storage, solid-state batteries have become a hot topic in recent years. From initial laboratory research to today's commercial exploration, solid-state batteries, with their unique structure and excellent performance, are gradually demonstrating their potential market value. So, can solid-state batteries truly dominate the market in the future?
The Origin and Development of Solid-State Batteries
The history of solid-state batteries can be traced back to the 1970s. Scientists discovered that using solid electrolytes to replace traditional liquid electrolytes could significantly improve battery safety and energy density. However, due to technical bottlenecks and material limitations, the performance of solid-state batteries was not ideal in the early stages and they failed to gain widespread application.
Currently, solid-state battery technology is continuously advancing. With the popularity of new energy vehicles, the advantages of solid-state batteries are particularly important. For example, they have improved energy density, longer lifespan, and no significant safety hazards. From a development perspective, solid-state lithium-ion battery technology is the most likely energy storage technology to achieve large-scale application in the next few years.
In response to this, MeriSun is also following the development of market demand, conducting testing and research on solid-state batteries, hoping to launch a new generation of solid-state lithium batteries and put them into production as soon as possible.
What are the differences between solid-state batteries and lithium-ion batteries?
Solid-state batteries mainly consist of a positive electrode, a negative electrode, a solid-state electrolyte, and a current collector. Among them, the solid-state electrolyte is the core of the solid-state battery, which uses solid materials to replace the liquid electrolyte in traditional lithium-ion batteries.
Lithium-ion batteries use liquid electrolytes, while solid-state lithium batteries utilize solid-state electrolytes. Solid-state electrolytes have a higher permittivity, lower ionic conductivity, but higher chemical and thermal stability, which can improve the safety performance of the battery. At the same time, solid-state batteries achieve higher energy density through optimized material structure and electrolyte design. This means that solid-state batteries can store more energy in the same volume or weight.
Due to the high ionic conductivity of solid-state electrolytes, solid-state batteries can complete ion migration and charge transfer faster during the charging process. This means that solid-state batteries can be fully charged in a shorter time, saving users valuable time. At the same time, solid-state batteries also have higher charging efficiency, reducing energy loss during the charging process.

Solid-state batteries have good high-temperature resistance and can operate between 60°C and 120°C. This also reduces the risk of internal failures caused by overheating due to the battery itself or external conditions.

At low temperatures, the viscosity of the electrolyte increases, and the ion conduction speed slows down, causing a mismatch with the electron migration speed in the external circuit. This leads to severe polarization of the battery, resulting in a sharp decrease in charging and discharging capacity. However, the use of solid-state electrolytes will not be affected by low-temperature environments, ensuring that the battery can still discharge even at -40°C.
Another advantage of solid-state batteries is their longer cycle life. Unlike traditional lithium-ion batteries, which gradually lose performance over time, solid-state batteries can maintain stable performance levels even after multiple cycles.
Accelerating the development of solid-state batteries as a complementary technology to lithium-ion batteries
Solid-state batteries have significant advantages, but their development still faces some challenges. As the technical data needs to undergo prolonged validation and mass production issues need to be resolved, the current energy storage market is still dominated by lithium-ion batteries. MeritSun will continue to fully realize the cooperation of lithium batteries in meeting global energy demand, and uphold an open and cooperative attitude to jointly promote the development and application of solid-state battery technology with global partners.
We firmly believe that under the guidance of solid-state battery technology, the energy storage field will usher in an even brighter future. At the same time, we also look forward to working with more partners to jointly promote the progress of energy transformation and sustainable development.
