“Dry batteries consist of approximately 10 parts and 10 kinds of raw material. As a device with a very simvple structure, it’s the quality of the materials that affects performance the most.
For this important reason, we don’t buy existing materials on the market, but instead develop and manufacture our own, or conduct joint-development with our suppliers.
This has resulted in our own accumulation of technologies, something no other brand can easily match.”
“We now produce manganese batteries in eight of our factories around the world. Over the last 30 years, we’ve managed to eliminate toxic substances from these batteries. We eliminated mercury in 1991, cadmium in 1993, and lead in 2013.
Although the process of making manganese batteries demands complicated techniques that took many years and many difficult challenges to overcome, we succeeded in making these cells safer.
Panasonic is the only manufacturer to have achieved this with specified-substance-free batteries produced in eight of our factories. We believe it’s our mission to provide safe and secure products to users, as batteries are needed by people all over the world.”
“It’s vital that batteries in auto applications maintain performance in harsh conditions where heat, cold, humidity, vibration, and impact are normal. Wherever there’s risk of harm to human life, high reliability is essential. Because lithium batteries employ materials that can generate heat, we pay scrupulous attention to ensure security.
An example of Panasonic lithium toughness is a new battery structure we developed for TMPS. This is a tire-pressure detection and data-transmission system installed in the interior surrounding of car tires.
It’s also the toughest place imaginable for batteries, and it led us to research robust battery structures and develop the world’s first patented LCM lithium-carbon technology related to electrode modification. Together, our lithium products hold more than 100 technology patents.”
