OSAKA -- Hitachi Zosen has developed a solid-state battery boasting one of the industry's highest capacities and tolerance for a wide range of temperatures, making it a candidate for use in satellites and industrial machinery.

The high-performance solid-state battery, unveiled Wednesday at an exhibition in Tokyo, features a capacity of 1,000 milliamp hours -- roughly seven times as much as the Japanese company's prior models. It can also operate in a temperature range from 100 degrees to minus 40 degrees Celsius.

With a lower risk of fires and more enhanced energy efficiency than conventional lithium-ion batteries, solid-state batteries are considered to be the next-generation power source. Leading manufacturers in solid-state technology include Japanese peers Toyota Motor and Murata Manufacturing, but they have yet to tackle such challenges as increasing capacity and trimming costs.

Hitachi Zosen sees demand for use in such harsh conditions as space and for industrial equipment operated in atypical environments. With plans to double the battery's capacity by 2025, the infrastructure and plant builder has begun small-scale production of a prototype and seeks to work with a partner on commercialization.

The company reached an agreement last month with the Japan Aerospace Exploration Agency to test practical applications of solid-state batteries in space. Camera equipment powered by a Hitachi Zosen battery will be sent to the country's Kibo module on the International Space Station as early as this fall, with tests to be conducted for six months.

Hitachi Zosen boasts a technology for producing a solid electrolyte without any use of sealant or solvent. Using fewer impurities reduces electrical resistance, enhancing the performance of batteries, it says.

While the new solid-state battery has reached a capacity milestone, it still trails far behind its lithium-ion counterparts. Those used in smartphones offer a capacity of thousands of milliampere per hour.

Good. Now make sure the Tiongs don't steal the tech.

Even other's vaccine labs also got hacked, I believe they will get a few of these through an independent third party and analyze with reverse engineering.

Ability to reverse engineer is good. But the durability and resilience remains to be seen.

Why not just use more batteries?

Why not just use more batteries?

Cost, weight, safety issues and bad for the environment.

I see it’s been a while since this topic was discussed, but I just wanted to ask—has anyone seen any updates or real-world testing news on these solid-state batteries since the announcement? I’m curious if they're any closer to hitting the market or if the tech is still stuck in labs. Would love to hear if someone’s keeping tabs on this.

I was looking into standard coin cell battery options the other day, and came across how some folks confuse the lr1130 battery equivalent stuff. Just a heads-up: lr1130 battery equivalent typically includes AG10, LR54, and 189, but they might have small voltage or size differences that could matter depending on the device. I switched mine and noticed shorter runtime, so definitely worth checking the specs before buying.

It's still stuck in the lab
But if anything

BMW is currently testing all-solid-state batteries (ASSB) in a specially equipped BMW i7 test vehicle in the Munich area. These tests are part of a real-world evaluation of the technology, with the aim of potentially integrating it into future BMW electric vehicles. The partnership with US-based Solid Power is key to this development, as they are providing the large-format, sulphide-based battery cells for the tests.

Here's a more detailed breakdown:

• Solid-state battery technology:
  Solid-state batteries are a promising next-generation technology for electric vehicles, offering potential improvements in energy density, safety, and cost compared to traditional lithium-ion batteries.
  
  
• BMW's testing program:
  BMW is using a specially outfitted BMW i7 to test the all-solid-state batteries from Solid Power.
  
  
• Partnership with Solid Power:
  BMW has a long-standing relationship with Solid Power, dating back to 2016, and has invested in the company.
  
  
• Testing in Munich:
  The i7 test vehicle is being operated in and around Munich, allowing BMW to evaluate the batteries in various real-world conditions.
  
  
• Potential benefits:
  Solid-state batteries could lead to longer driving ranges, reduced battery size and weight, and improved safety in electric vehicles.
