Hopax started the expansion of its production center for additives for Lithium-ion batteries and electroplating

Hopax has just started the expansion of its manufacturing facilities in Changshu, China. Changshu is Hopax’s production center for additives used in Li-ion battery electrolytes and electroplating.

The project is Hopax’s answer to the increasing demand from copper plating solutions manufacturers and lithium-ion batteries manufacturers for the chemicals produced in Changshu.

Changshu factory’s expansion is expected to be finished by the end of March, 2019, and will increase Hopax’s manufacturing capacity for the following chemicals:

Additive for Li-ion battery electrolytes	Old capacity	New capacity
1,3 PS (Propane Sultone) Electronic grade	1000 tons/year	1500 tons/year

* The addition of 1,3 PS to Li-ion battery electrolytes can improve the compactness of the passivation film formed on the surface of the negative electrode during charge and discharge. This additive also prevents metal dissolution and suppression and electrolyte oxidation, which in turn increases life cycle and stability.

Additives for electroplating	Old capacity	New capacity	Uses
PPS	300 tons/year	400 tons/year	Brightening agent for copper plating solutions
SPS	100 tons/year	180 tons/year	Brightening agent for copper plating solutions
MPS	80 tons/year	120 tons/year	Brightening agent for copper plating solutions

This is Changshu plant’s second large expansion after its establishment in 2005. Since then, Hopax has invested more than USD 53 million in expansions to meet the growing demand from manufacturers of Li-ion batteries and electroplating solutions.

Through this strategic move Hopax aims to maintain on-time deliveries to long time partners in these industries and have stock availability for new customers and projects.
