All-solid-state battery PSB-401010H

lithium-ionsquare2.3 V

Maxell's sulfide-based all-solid-state batteries, with their superior ion conductivity, are expected to be applicable in a wide range of applications, including power sources requiring high output, such as sensors and wireless communications.

Unlike oxide-based all-solid-state batteries, the sulfide-based all-solid-state batteries developed by Maxell do not require high-temperature sintering in the manufacturing process, making them highly mass producible. These batteries feature high output and high capacity. Moreover, Maxell's all-solid-state batteries utilize an argyrodite-type solid electrolyte, which stands out for its exceptional balance of mass production, stability, ion conductivity, and moldability among sulfide-based solid electrolytes. This technology effectively suppresses the increase in resistance associated with repeated charge-discharge cycles and long-term storage, resulting in improved discharge capacity under high load conditions after long-term cycles or storage compared to conventional batteries with liquid electrolyte.

Thes PSB401010H battery uses a ceramic package housing to ensure heat resistance and airtightness. The battery can be surface-mounted using reflow soldering.

Typical Applications:
- Factory automation devices for power backup
- Automotive electronics
- Environmental sensors
- Infrastructure monitoring systems"

Features
1.Wide discharge temperature range
The battery can be discharged over a wide temperature range from -50°C to +125°C, beyond the capabilities of conventional lithium-ion batteries.

2.Enhanced durability and long service life *1
The batteries achieve a level of durability and service life that is difficult for conventional batteries to attain. As battery replacement is required less frequently, they contribute to maintenance efficiency in harsh environments and help alleviate the impact of a declining workforce.

3.High-rate discharge capability *2
The use of sulfide-based solid electrolytes with high ionic conductivity enables high-rate discharge. Combined with low-power wireless communication technologies such as Bluetooth® Low Energy and LPWA, the battery supports the development of IoT-enabled devices capable of real-time monitoring.

4.High safety
With no risk of liquid leakage, explosion, or ignition, the batteries provide a high level of safety. This makes them suitable for a wide range of applications, including harsh-environment equipment as well as medical and healthcare devices, where safety is essential.

Annotation
*1 Enhanced durability and long service life: The Maxell conventional coin-type lithium-ion battery (927 size) can maintain 90% capacity for 10 days, while the all-solid-state battery can maintain 90% capacity for 100 days, based on accelerated testing at 60 deg. C.

*2 High-rate discharge capability: These characteristics are equivalent to the rated capacity and the maximum discharge current of Maxell’s conventional coin type lithium-ion rechargeable battery (927 size).

*3 Safety: No ignition or smoke generation is seen in various safety tests such as heating at 350 deg. C, nail penetration, and external short circuit.
