Japanese media: China, Japan and South Korea compete for new battery
research and development Japanese companies are making a comeback with cr2032
button battery
According to Japanese media, cr2032 button battery, which are regarded as
the top seeds of a new generation of batteries, have the potential to be
popularized in daily life and industry. In terms of small-sized products that
can be placed on fingertips, Japanese electronic components company TDK has come
up with a practical timetable. cr2032 button battery have attracted attention
because they are considered to be suitable for pure electric vehicles (EVs), but
they may be the first to be used in home appliances. Japanese companies hope to
make a comeback in battery development competition with Chinese and Korean
companies.
According to a report by Nihon Keizai Shimbun on November 26, cr2032 button
battery and lithium-ion batteries are both rechargeable batteries, but their
energy density has increased several times and their safety has also been
improved. TDK has developed a chip-type all-solid-state battery that is several
millimeters square and can be recharged 1,000 times. Sample supply has been
started and the mass production system is being improved. Be the first in the
world to be officially put into practical use.
According to reports, TDK hopes to first apply small products to air
conditioners and lighting in homes, offices, and factories. For example,
lithium-ion batteries are embedded into temperature sensors to replace
button-type alkaline batteries.
The report pointed out that a variety of new-generation batteries are being
developed around the world, and all-solid-state lithium-ion batteries are
considered to be one of them closer to practical use. So far, it is expected to
be a substitute for lithium-ion batteries for pure electric vehicles.
According to reports, cr2032 button battery can extend vehicle cruising
range and shorten charging time. Toyota strives to achieve practical use by the
first half of the 2020s. Volkswagen of Germany also plans to complete its mass
production system by around 2025. However, neither party has reached the stage
where they can ship goods.
If small-size products like TDK's are launched on the market, the
application scope of cr2032 button battery will not be limited to pure electric
vehicles, and the possibility of being used in various fields of society will
increase. Although there are still issues in increasing the capacity of cr2032
button battery, they may be used in various home appliances such as personal
computers and mobile phones in the future.
To this end, relevant companies are racing to accelerate development.
Japanese electronic components company Taiyo Yuden plans to put an
all-solid-state battery with a size of several centimeters square to practical
use around 2020, which is expected to be used in smart watches and other
applications. In addition, Murata Manufacturing Co., Ltd. is developing products
with a thickness of 50 microns and strives to be used in wearable devices such
as contact lenses.
Hitachi Zosen strives to apply cr2032 button battery to special aerospace
fields. First, we will promote talent recruitment in this field in 2019, and
after mastering the technology, we will enter the field of pure electric
vehicles in the second half of the 2020s.
The report pointed out that the competition around the development of
batteries from all-solid-state lithium-ion battery manufacturers has expanded to
the world. In addition to South Korea's Samsung SDI and LG Chem, which are
promoting the development of batteries for pure electric vehicles, startups from
various countries are also joining in.
Japanese companies have accumulated rich experience in product
manufacturing fields such as industrial materials and processing technology. In
the battery field, it also has the potential to lead technology development. For
example, Sony has realized the practical use of lithium-ion batteries for the
first time in the world. However, with the popularization of manufacturing
technology, Japanese companies have lost market share to Chinese and Korean
companies.
It is said that in the field of pure electric vehicle batteries, the
shipment volume of my country's Contemporary Amperex Technology Co., Ltd. (CATL)
surpassed Panasonic in 2017 and ranked first in the world. The upgrading of the
battery market brought about by cr2032 button battery will become an opportunity
for Japanese companies to make a comeback.
Dongguan Juda Electronics Co., Ltd. was established in 2002 and is
headquartered in Goldman Sachs Technology Park, Nancheng District, Dongguan
City, Guangdong Province, my country. It is a company that provides special
needs for global users in mobile power supplies, energy storage power supplies,
power supplies and backup power supplies. A national high-tech company
specializing in customized solutions and products for lithium battery
systems.
