据美通社最新消息，由独立机构开展的eestor高能电容eesu第三次测试工作于5月30日开始，首批测量结果今日公布：
在2009年EESU第一次测试结果耐压极限已经提高到1100V/UM，如果下一步测量电压从目前20V/UM提升到500V/UM，储能密度有望从目前的77WH/L提高到5kWH/L，超锂电池储能密度3-5倍。
如果实用了，电动车的瓶颈就被打破了，新技术革命啊
EEstor, Inc. is Announcing the Certification of Our New Layer Material and Voltage vs. Capacitance

CEDAR PARK, Texas, June 6, 2013 /PRNewswire/ -- EEStor, Inc. is announcing that we have completed our initial certification of our new layer material and the voltage vs. capacitance of our composition-modified barium titanate (CMBT) powders. The data was certified by Criteria Labs which is located in Austin, Texas. The certification data is indicated below:

CAPACITANCE INSULATION RESISTANCE – NEW LAYER MATERIAL
The average for the reading on the four layers is as follows:
Capacitance Average:
0.22 micro farads
Insulation Resistance Average
10.65 mega ohms

The test data indicates that the EEStor, Inc. new layer material has the capability to provide high capacitance along with high insulation resistance. EEStor, Inc. will now be tailoring this new layer material for increase capacitance and resistance up to full product certification.
The data also indicated the stability of the CMBT powders/composite layer to capacitance vs. voltage. This indicates that advantage of our CMBT powders being in the paraelectric phase where for all practical purposes dielectric saturation does not exist.
