M (NASDAQ: MMM) is investing in research and manufacturing of novel Silicon (Si) based 3M
anode materials. 3M’s investments into the high- energy metal based anode for lithium ion batteries include matching a recent US Department of Energy (DOE) grant for $4.6 million as part of efforts to build more energy-efficient vehicles. The research will help to develop and integrate new cell materials that will make a transformative change in energy density and in cost in lithium ion batteries used in electric vehi- cles.
3M was recently granted another US patent, 8,071,238 for its Silicon anode compositions that can increase cell capacity by over 40% when matched with high-energy battery cathodes.

Moreover, 3M published aerospace news: Substruc- ture corrosion in aircraft areas exposed to recurring moisture, such as lavatories, galleys and doorways, is a major industry challenge. Replacing floor panels and beams in the substructure extends downtime and can cost anywhere from $30,000 to $100,000 per aircraft, making protection a high priority.
3M Aerospace is responding to this need by ma- king the protection of these “wet areas” easier with the introduction of improved 3M™ Polyurethane Protective Tapes that cover the seams in floor panel
joints and wide-area tapes to protect larger areas exposed to moisture. These flame retardant tapes provide an excellent, durable moisture barrier with a long service life. 3M wet area protection tapes are constructed of an extremely tough, puncture-resi- stant thermoplastic elastomer coated with a pressure sensitive adhesive. The tapes provide a durable and flame-resistant barrier that prevents costly corrosion damage to aircraft floor systems, and can be installed easily and quickly for a variety of applications, in- cluding seam sealing, wide wet area protection and beam protection.
High elongation gives the tapes excellent conforma- bility, providing effective coverage of contoured are- as, and their dual liner construction results in better productivity and fewer wrinkles or bubbles during application. Furthermore, the transparency of the seam sealing tape allows for easy visual inspection of floor panel sealants.

3M New Ventures has also invested in Zephyr Tech- nology, a developer of real-time physiological moni- toring solutions for well-being applications in health- care, first responder, sports, military, and industrial markets. The series C financing round also included investments by Alsop Louie Partners, Motorola Solutions Venture Capital, and others.
