Researchers design long-lasting, solid-state lithium battery

Recommendable! 

Do not accept electric vehicles is the only solution as politicians and propagandists want you to believe! There is hydrogen power or synthetic and recyclable fuels and more out there. Anyway, thanks to modern technologies like video conferencing and home office, the need for e.g. commuting or business travel will be significantly reduced in the future.

Do not believe the myth that electric vehicles are much more environmentally friendly than gasoline powered vehicles when you consider e.g. the entire lifecycle of a vehicle and its components!

I am not sure the "cycling performance" of this new battery is really impressive and meets the demands of e.g. frequent drivers.

"Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today’s lithium-ion batteries fall short of what’s needed — they’re too heavy, too expensive and take too long to charge. ... “A lithium-metal battery ... But the stability of these batteries has always been poor.” ...
This battery technology could increase the lifetime of electric vehicles to that of the gasoline cars — 10 to 15 years — without the need to replace the battery. ... With its high current density, the battery could pave the way for electric vehicles that can fully charge within 10 to 20 minutes. ...
These [dendrites] grow like roots into the electrolyte and pierce the barrier separating the anode and cathode, causing the battery to short or even catch fire. ... The battery is also self-healing; its chemistry allows it to backfill holes created by the dendrites."

"... However, in practice it still remains challenging to realise a lithium metal anode for batteries, because micrometre- or submicrometre-sized cracks in ceramic pellets can frequently be generated during battery assembly or long-time cycling3,5. Once cracks form, lithium dendrite penetration is inevitable. Here we describe a solid-state battery design with a hierarchy of interface stabilities (to lithium metal responses), to achieve an ultrahigh current density with no lithium dendrite penetration. Our multilayer design has the structure of a less-stable electrolyte sandwiched between more-stable solid electrolytes, which prevents any lithium dendrite growth through well localized decompositions in the less stable electrolyte layer. ... The cycling performance of the lithium metal anode paired with a LiNi0.8Mn0.1Co0.1O2 cathode is very stable, with an 82 per cent capacity retention after 10,000 cycles at a 20C rate (8.6 milliamps per centimetre squared) and 81.3 per cent capacity retention after 2,000 cycles at a 1.5C rate (0.64 milliamps per centimetre squared). ..."

This picture from the Harvard Gazette article is just too cute! It suggests that the chemistry going on in your car battery is like a healthy, wholesome sandwich. This is disturbing propaganda!
