TDK Solid State Battery announcement - probably one of the few honest, realistic announcements about SSBs

We have seen so many "Solid State Batteries in 2 years" type announcements for the past 10 years. This SSB for electronic devices announcement from TDK seems to be honest and humble, and mentions the challenges to adapt it from small devices to cars.

Apple supplier TDK claims solid-state battery breakthrough
Smartphone battery leader says new material will boost energy storage for smaller gadgets first

The batteries set to be produced will be made of an all-ceramic material, with oxide-based solid electrolyte and lithium alloy anodes. The high capability of the battery to store electrical charge, TDK said, would allow for smaller device sizes and longer operating times, while the oxide offered a high degree of stability and thus safety. The battery technology is designed to be used in smaller-sized cells, replacing existing coin-shaped batteries found in watches and other small electronics.
...
The ceramic material used by TDK means that larger-sized batteries would be more fragile, meaning the technical challenge of making batteries for cars or even smartphones will not be surmounted in the foreseeable future, according to the company.
...
Kevin Shang, senior research analyst at Wood Mackenzie, a data and analytics firm, said that “unfavourable mechanical properties”, as well as the difficulty and cost of mass production, are challenges for moving the application of solid-state oxide-based batteries into smartphones. Industry experts believe the most significant use case for solid-state batteries could be in electric cars by enabling greater driving range. Japanese companies are in the vanguard of a push to commercialise the technology: Toyota is aiming for as early as 2027, Nissan the year after and Honda by the end of the decade.

However, there is still scepticism about how quickly the much-hyped technology can be realised, particularly the larger batteries needed for electric vehicles. Robin Zeng, founder and chief executive of CATL, the world’s biggest electric vehicle battery manufacturer, told the Financial Times in March that solid-state batteries did not work well enough, lacked durability and still had safety problems.

Quantumscape is likely the furthest along for solid state batteries. They have independently tested their batteries and they are performing well. Now their challenge is can the manufacture at scale reliably which is what they are doing now is building manufacturing capacity.

Volkswagen is a major investor and they have signed 6 unnamed OEM’s and hopefully Rivian is one of them. They have demonstrated reliability a recharge rate of 80% in 15 mins and the theoretical limit is as little as 5 mins recharge. They also have done 1,000 recharges with 5% or less battery degradation if I’m remembering right. I think we are closer to SSB reality…in 2 years :)

This is a good summary of where they are

That guy must not have cleared those comments with the marketing department.

Best honest take on solid state batteries since CATL's exec came out in favour of sodium based batteries over solid state.

Toyota has been a bit of a joke to me in BEV tech. They took years to bring a dedicated BEV to market, and when they did, the "BusyForks" charges like the old NiCad batteries in my Tyco Typhoon from the 80's. They come out every 2 years to reaffirm that they are 2 years out from a vehicle offering with "1200 miles of range that charges in 10 minutes or less" and they are a leader in BEV tech "just wait two years".
