THE TECH
Automotive supplier MAHLE has developed a new oil
management module for EVs. The module includes a
filter, electric oil pumps, and a thermostat.
MAHLE’s new module features a lightweight design,
minimal pressure losses and low package constraints.
The pressure-side filtration concept offers flexibility in
the type, size, and power rating of the pump, reducing
the risk of foaming and cavitation on the oil pump’s
suction side.
Jörg Stratmann, CEO of MAHLE, said, “The technolo-
gies we have used are proven and suitable for large-scale
production. Our approach of bringing together all the
functions in one component makes our oil management
module exceptional. We allow for a lot of design flexi-
bility and combine what is technically feasible with what
makes economic sense.”
MAHLE launches oil
management module for EVs
Chinese chemical manufacturers Haiyi and East Chem
are launching local production of OCSiAl’s TUBALL
BATT, a single-wall carbon nanotube (SWCNT) additive
for silicon anodes for EVs.
SWCNTs are designed to improve battery performance
and cycle life when added to a silicon anode. Haiyi and
East Chem aim for a combined annual production vol-
ume of 7,000 metric tons of the TUBALL BATT.
Zhijun Liu, General Manager of Haiyi, said, “With the
guidance and support of the OCSiAl technical team over
the past 3 years, we have now launched the production of
TUBALL SWCNT dispersions in China. Local produc-
tion allows Chinese battery manufacturers to greatly
reduce the costs by using TUBALL BATT conductive ad-
ditive. We have obtained certification from local battery
manufacturers, and have now started to sell large batch-
es. Haiyi will continue to expand its production capacity
of SWCNT dispersions, and we welcome visits from
colleagues from the industry to our production plant.”
Jian Lin, VP of R&D at BAK Power Battery, said,
“SWCNTs are the best currently available solution on the
market, with their excellent performance being far supe-
rior to that of other similar conductive additives. Due to
their high aspect ratio and G/D ratio, dispersed SWCNTs
are very effective in batteries. The addition of SWCNTs
in anodes hugely reduces capacity loss with aging and
improves cycle life.”Two Chinese firms launch
