BEIJING, Dec. 22 (Xinhua) -- With cold weather hitting most regions in China recently, owners of electric vehicles (EVs) and scooters are increasingly concerned with the power supply upon each charge, as lithium-ion batteries and lead-acid batteries, which are widely used on EVs and electric two-wheelers, tend to suffer from reduced performance under low temperature.
Aiming to tackle this issue, CNAE Energy (Yangzhou) Co., Ltd. (CNAE) has been actively engaged in research and development of sodium-ion batteries, having accumulated over 20 related patents and formed a comprehensive business layout centering around sodium-ion battery materials and products.
Compared with lithium-ion and lead-acid batteries, sodium-ion batteries have significant advantage in terms of low temperature performance, maintaining over 90 percent of power capacity at minus 20 degrees Celsius, whereas lithium-ion and lead-acid batteries could lose up to around 50 percent of power capacity under the same circumstance. At the same time, sodium-ion batteries are showing better performance in terms of fast charging under low temperature as well.
In addition, sodium-ion batteries are also recognized as safer, with lower costs and more abundant raw material reserves. Sodium-ion battery pack for two-wheelers is one of the major products of CNAE, constituting the company's core competence thanks to the advantages of sodium-ion batteries.
Once put into mass production, sodium-ion batteries should be nearly half the price of lithium-ion batteries, estimated by CNAE. As an emerging enterprise in the sodium-ion battery industry, the company is committed to promoting the application of sodium-ion batteries in transportation electrification scenarios and energy storage fields.
