“With a stream of major cell suppliers regularly announcing ‘major’ breakthroughs in solid-state cell technology, it is proving difficult to discern the reality of the state of play at present.” This from GlobalData’s dedicated research platform, the Automotive Intelligence Center, which was released today as an analyst’s comment.*
“The harsh reality is that 90% of news, plans and solid-state plant activity appears to be bogus, as start of production (SOP) dates slip or vanish, with this being particularly true of information coming from China,” said Oliver Petschenyk Powertrain Analyst at GlobalData.
“One major player in the solid-state landscape announced very recently that it was re-focusing its efforts on cost reduction and given that its primary focus is solid-state, one does question the likelihood of a strong business case underpinning the product. Theoretically, solid-state cells offer a true benefit to the light vehicle automotive market because, in their most basic form, such cells are volumetrically more energy-dense than current mass market solutions as there is much less ‘wasted’ space between the current collectors.
“However, in reality, achieving a mass production-capable product remains a long way off. Indeed, multiple companies are claiming that they have achieved the manufacture of solid-state batteries (SSBs) already, but they are produced very expensively and only in small batches, and yes, they do offer an energy density benefit, but there is still no real business case until manufacturing methods become significantly cheaper.
“The most promising research in solid-state technology from a mass-manufacture viability standpoint seems to suggest a ceramic-based electrolyte which is layered with the electrodes. But therein lies the mass manufacture issue – the core material is ceramic/glass meaning that the structure is incredibly fragile. On top of this, the interface between the current collectors needs to be so perfect that factories would need to be hermetically sealed, and the equipment used would need to be at a nanometer level of precision, somewhat like the semiconductor industry.
Solid-state cell technology has been on many companies’ agendas for a long time, but postponed release dates – a well-known Japanese OEM being the worst in this regard – and other companies dialing back investments indicate a low likelihood of true solid-state coming to fruition this decade in the light vehicle sector. Semi-solid-state cells offer slightly greater manufacturing tolerance with some such cells using an inert liquid to act as a ‘transfer’ device to aid molecular transfer. In fact, a China-based major car manufacturer does offer a 150kWh semi-solid-state battery pack for use on the roads today. But at a cost of more than €35,000, it isn’t currently an option to be factory-fitted and sold along with the car, rather customers can rent this battery at a daily or weekly charge, said Petschenyk.

About Ken Zino
Ken Zino, editor and publisher of AutoInformed, is a versatile auto industry participant with global experience spanning decades in print and broadcast journalism, as well as social media. He has automobile testing, marketing, public relations and communications experience. He is past president of The International Motor Press Assn, the Detroit Press Club, founding member and first President of the Automotive Press Assn. He is a member of APA, IMPA and the Midwest Automotive Press Assn.
He also brings an historical perspective while citing their contemporary relevance of the work of legendary auto writers such as Ken Purdy, Jim Dunne or Jerry Flint, or writers such as Red Smith, Mark Twain, Thomas Jefferson – all to bring perspective to a chaotic automotive universe.
Above all, decades after he first drove a car, Zino still revels in the sound of the exhaust as the throttle is blipped during a downshift and the driver’s rush that occurs when the entry, apex and exit points of a turn are smoothly and swiftly crossed. It’s the beginning of a perfect lap.
AutoInformed has an editorial philosophy that loves transportation machines of all kinds while promoting critical thinking about the future use of cars and trucks.
Zino builds AutoInformed from his background in automotive journalism starting at Hearst Publishing in New York City on Motor and MotorTech Magazines and car testing where he reviewed hundreds of vehicles in his decade-long stint as the Detroit Bureau Chief of Road & Track magazine. Zino has also worked in Europe, and Asia – now the largest automotive market in the world with China at its center.
