1000 Prototypes in a Day

“Dry batteries are typically built with 10 components and 10 types of raw material compounds. As a product with a very simple structure, it’s the quality of the materials and the engineering expertise in how they are assembled that affects performance the most. For this important reason, we don’t buy materials on the open market; we develop our own, or conduct joint-development with our suppliers. This has resulted in our accumulation of technologies and “know-how”; 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 products to users throughout the world.”

“It is vital that batteries used in auto applications maintain performance in harsh conditions, where cells are regularly subjected to heat, cold, humidity, vibration and impact. Wherever there is a risk of harm, high reliability is essential. As a result of the use of materials that can generate heat, we are extremely diligent and precise in our attention to ensuring product safety.
 One example of Panasonic’s lithium battery “toughness” is a new battery structure we developed for the auto manufacturers’ Tire Pressure Monitoring Systems, or TMPS. This tire-pressure detection and data-transmission system requires battery power to be placed on the inside of the car's tire, where it is attached to the inner part of the rim. It is one of the toughest environments imaginable for batteries. This challenge 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.”
