R&D

l After many years of technological accumulation, our company had developed five types of battery series which contain LiCoO2, LiMnO2, LiFePo4, Li4Ti5O12 and ternary material systems. Batteries consist of 21 specifications and own capacity covering from 2Ah to 400Ah. Significantly decreased the cost of lithium-ion battery through advanced manufacture technologies. In 2012, AET had developed 100Ah LiFePO4 cylindrical cell, which has reached the international advanced level.

 

l Our company had developed the lithium-ion batteries of high-rate discharge, low thermal generation, high volumetric energy density and other good performance which all reach the international advanced level. Currently, we have developed a type of 2Ah/3Ah high-rate cylindrical battery which can discharge at 100C in the low temperature 20 degree below zero.

 

l AET owns 18 patents related to lithium-ion battery, including materials, battery structure, manufacturing etc. And around 10 more patents are in progress of applying. Applied patents are as follows
