Enpower Greentech Inc. and SoftBank Corp. Successfully Verify 450+ Wh/kg Energy Density Battery and Succeed in Development of Core Technologies for Longer Battery LifeJoint Research Agreement • March 14th, 2021
Contract Type FiledMarch 14th, 2021In March 2020, Enpower Greentech Inc. (“Enpower Greentech”) and SoftBank Corp. (“SoftBank”) signed a joint research agreement for the development of lightweight, large capacity, and high specific energy density next generation batteries, with applications for IoT and cellular base stations. Both companies have just successfully verified a high energy density (450+Wh/kg) lithium metal battery, and are also pleased to announce the successful development of core technologies that will extend the service life of lithium metal batteries. The core technologies developed thus far include an ultra-thin coating film (<10nm), which prevents dendrites1* from forming on the surface of lithium metal, and an electrolyte, which achieves both high voltage and high coulombic efficiency (charge-discharge efficiency) 2*.
