Most of our devices run ( not for long enough ) on lithium ion batteries . But there could be a new , erstwhile kid on the block — in the soma of a solid - Department of State stamp battery that can hold in twice the charge as li - on .
There ’s nothing unexampled about the solid - state battery : it simply swap the liquid electrolyte in conventional Li - ion battery for a solid one , bringing a Brobdingnagian increase in the amount of energy a barrage fire can contain . They ’re also safer — because it ’s the liquid electrolyte in li - on batteries that ’s inflammable .
But solid - state barrage fire have , until now , been prohibitively expensive because of the mode they have to be made . They require layers of the self-coloured electrolyte be built up , one at a sentence — but high - precision is required , because any gaps , anywhere in the electrolyte , would cause a little circuit in the cellular phone , which is a Bad Thing . In turn , cells had to be made slowly , and even then many were turn down .
Now though , report Technology Review , Applied Materials , one of the world ’s biggest equipment provider for the semiconductor and display diligence , claims it ’s worked out how to make them cheaply . Indeed , it ’s developed a fresh strain of manufacturing tools which perform exceedingly high - preciseness deposition at large scales , and they ’re already being used for prototyping of new whole - state batteries .
While Applied Materials wo n’t give away who its customers for the novel machinery are — though it does say that habiliment will be a key initial grocery — the development is incredibly positive . The nature of substantial - state battery signify that they can match content with a smaller shape agent , or be crafted into unusual , and even pliant , SHAPE . The battery future looks solid , then . [ Technology Review ]
