China’s Tianneng Power International Ltd said revenue for the first half of 2017 has been boosted by a 26.5% rise in lead battery sales, compared to the year-ago period.
In newly-released interim figures for the period up to 30 June, Tianneng posted revenue of more than CNY10 billion ($1.5b).
Johnson Controls has announced two multi-year research projects at the University of Wisconsin–Madison (UW–Madison) aimed at enhancing lead-acid start-stop batteries and energy storage systems.
The first project will focus on identifying the ageing mechanisms of absorbent glass mat (AGM) batteries and supporting systems in start-stop applications.
One of China’s largest lead-acid battery manufacturers has opened a factory to make start-stop batteries that it will supply directly to OEM firms such as Audi, BMW, Mercedes and Volkswagen.
The factory, in Boading in the Hebei province, China, has an annual capacity of five million batteries.
