As the world electrifies, the race is on to build better batteries that take you further, charge faster, are safer, and more sustainable.  Dutch startup LionVolt is developing 3D solid-state batteries that it says ticks all the above — and it’s just raised €15mn to scale up production. LionVolt — a spinout from TNO’s Holst Centre in Eindhoven, the Netherlands — is working on solid-state batteries that don’t contain the liquid lithium common in standard lithium-ion devices.  Instead, the batteries are made up of a thin film containing billions of solid pillars, creating a patented 3D architecture with a large…This story continues at The Next Web
