Hitachi successfully develops new lithium batteries The energy density will be increased by two times

Recently, Maxell, a subsidiary of Hitachi, has successfully developed a new anode material to create a new lithium battery with an energy density about twice that of the current battery, which is expected to be used in
wearable devices.

It is understood that this new lithium battery, named "ULSiON", is covered with a carbon coating on the silicon-based oxide layer, and the SiO-C material with finer particles is obtained, and is used as the negative electrode
of the lithium battery.
Compared with the current 3000mAh mainstream lithium battery, the new lithium battery has twice the energy density and lower low voltage torsion curve, so it can withstand a cut-off voltage as low as 2V, and can use the power in the battery more completely
.

The new lithium battery is expected to be available at the wearable device conference in Japan in February, but there is no specific timeline
for when mass production will occur.
