solid lithium-ion batteries. The company, which received $4 million in
funding from the Advanced Research Projects Agency Energy program this
spring, says it can print solid batteries that offer three times more
storage than liquid lithium-ion batteries of the same size. This boost
in energy storage is possible primarily because the company's
all-solid batteries don't require many of the support structures and
materials that take up space in conventional batteries, making more
space for energy storage.
Planar Energy expects to reduce capital costs by half compared with
solid-state battery manufacturing using high-vacuum machinery. And the
company says its processes can be used to make cells big enough to
power electric vehicles.'
