Technology:
NEC developed a
technology to increase the distance per charge of a lithium-ion battery by 30%.
Currently, the maximum distance of a lithium-ion battery is 200 km, and NEC successfully
increased the distance to 260 km. The company plans to put the new technology
into practical use in less than two years.
Increasing a
storage capacity of a lithium-ion battery by increasing power voltage generates
gases inside the battery and shortens its life. NEC successfully developed a
new electrode material and new electrolyte, each of which does not allow gases
to generate easily even in high power voltage. The new technology can increase a
storage capacity without using such rare materials as cobalt for the electrode.
Accordingly, the life and production cost of the new lithium-ion battery are
the same as the lithium-ion battery loaded onto Nissan’s Leaf. NEC will release
the new technology to other battery manufacturers.
