CATL’s Wu honoured for Li battery safety work

July 13, 2023: Wu Kai, the chief scientist and co-president of China’s Up to date Amperex Expertise and his workforce, was honored for contributions to lithium ion battery security by the European Patent Workplace (EPO).

The European Inventor Award 2023 within the non-EPO nations class for transport tech was introduced on July 4 at a ceremony in Spain.

In keeping with the EPO, Wu and his workforce (pictured) have been working since 2019 on cell-to-pack know-how that makes use of an built-in construction to optimize the house utilized by the battery pack and improve the vitality density of the pack. .

Different improvements embrace a security machine that short-circuits an overcharged battery.

The EPO says the machine has an embossed flip-top cowl that does not soften, whereas the quilt acts as a barrier that dissipates warmth and absorbs temperature and extra stress.

When overheating inside a battery cell causes a rise in air stress, the quilt bends and makes contact with the conductive pole piece of the battery, thus stopping the charging course of.

Wu stated: “I hope that extra inventors will dedicate themselves to e-mobility and vitality switch in order that collectively we will create extra improvements for the advantage of mankind.”

Wu, who can be the co-president of CATL’s Future Power Analysis Institute, started his profession as a instructor earlier than transferring into trade to work in magnetic recording.

In 2002 he accepted a place as a technical director of an organization manufacturing lithium batteries then joined CATL in 2012.

The European Inventor Award was launched by the EPO in 2006.
