Hitachi Zosen: World’s largest capacity all-solid-state battery: Operates at -40 ° C to 100 ° C
Hitachi Zosen:
Hitachi Zosen has developed the world’s largest all-solid-state battery.
The capacity is 1000 ㍉㌂, which is about 7 times larger than the conventional product of Hitachi Zosen.
The feature is that it operates in a special environment such as high temperature.
The range of utilization is likely to expand, such as artificial satellites and industrial machinery.
From the beginning of the year, we started small-scale production of prototypes at our factory in Osaka.
Exhibition in Tokyo:
It was announced at an exhibition held in Tokyo on March 3rd.
It works even in a harsh environment of -40 degrees Celsius to 100 degrees Celsius.
We see demand for industrial machinery and space applications in special environments.
The goal of increasing the 2025 capacity several times in prospect.
Capacity / cost is an issue:
All-solid-state batteries
Compared to lithium-ion batteries
Hard to burn and highly energy efficient
It is attracting attention as a next-generation battery.
However, small capacity and high cost are issues.
For example, even lithium-ion batteries for smartphones generally have a capacity of several thousand meters.
All-solid-state batteries are still inferior to lithium-ion batteries.
Hitachi Zosen’s proprietary technology:
Hitachi Zosen has “a unique technology for manufacturing sheet-shaped electrolytes without using adhesives or solvents.”
By reducing impurities, the electrical resistance is reduced and the performance of the battery is improved.

All-solid-state lithium-ion battery [AS-LiB®]
Utilizing the technology of the Hitz Hitachi Zosen Group, we have developed a unique manufacturing method.
Since the solid electrolyte is flame-retardant, it maintains high safety.
In addition, a wide operating temperature range of -40 ° C to 100 ° C has been achieved.
Features:
All-solid-state lithium-ion batteries
Positive electrode layer,
Solid electrolyte (SE) layer,
It is a structure in which negative electrode layers are laminated.
Solid electrolyte (SE):
SE allows only lithium ions to pass through and retains the function of the separator.
Lithium ions are charged and discharged by moving back and forth between the positive electrode and the negative electrode via SE.
Application fields and products (assumed):
Batteries for special environments that take advantage of the wide operating temperature range
Industrial equipment, space applications, power supplies in harsh environments, etc.
Medical batteries that take advantage of high safety
Medical equipment, medical equipment, etc.
Next-generation automotive batteries
