3003 aluminum coil for power battery flexible connection

According to the data released by the China Automobile Association, from January to July 2017, the production and sales of new energy vehicles in China completed 272,000 units and 251,000 units respectively, an increase of 26.2% and 21.5% year-on-year respectively. The rapid growth of new energy vehicle production and sales will certainly drive the rapid development of the lithium battery industry, according to the latest data from the National Bureau of Statistics, from January to August 2017, the cumulative total output of lithium batteries in China was 666,129.2 million, an increase of 51.18% year-on-year.

Affected by this, the performance of a number of enterprises related to the lithium battery industry showed varying degrees of growth, as of July 31, 2017, of the 85 lithium battery-related listed companies released in the half-yearly forecast, the net profit is expected to exceed 500 million yuan in 7; more than 100 million yuan in 39, accounting for 45.88%.

3003 aluminum coil for power battery

All walks of life, lithium battery industry performance growth also promote the development of aluminum processing industry, lithium battery with aluminum foil rolls really a lot of places, including in the lithium battery soft package connection using 3003 aluminum coil. 3003 aluminum coil has high plasticity, corrosion resistance, electrical and thermal conductivity, but low strength, heat treatment can not strengthen the machinability is not good; can gas welding, hydrogen atomic welding and contact welding, not easy to braze; easy to withstand Various pressure processing and extension, bending.

We actively invest in research and development work, after many trials, 3003-O aluminum coil in the soft connection experiments successfully, the narrowest can be cut to 15mm, can meet the production needs of power batteries. At the same time 3003 aluminum coil can also be used on the power battery explosion-proof valve, effectively prevent the battery from continuing to charge after a full charge, reducing the chances of battery explosion.
