Battery
Cracks developed in the electrode tears the capsule and release CNT to restore the flow of current.
->Self-Healing
This is the structure which put CNT capsules into virus.
1. How is it better ?
The capsules doesn’t have to move to the target. I

현재 차세대 이차전지에 대한 관심이 집중되면서 2차전지의 한계로 지적되던 에너지 밀도 상승의 한계, 안정성에 대한 불안감, 그리고 높은 원가 부담을 개선하기 위한 새로운 형태의 전지가 등장함은 물론 과거에 소개되었던 개념까지 재조명 받고 있다. 풍부한 자원인 황을 활용하여
Structure of Thin film batteries
Encapsulation
Direct connect with battery’s stability
Protection the anode from exterior
Ex) Parlylene, Cr, V
Anode
Desorbs electrons as discharging
Ex) Li, SnO2, C
Electrolyte
High density of charge carrier
High density of vacancy & interstitial site
Low activation Energy of hopping
Cathode
Absorb electrons as discharging
Direct connect w
III-III. How the product works.
In case of Nexus one, it's not purchasable in the outdoor market. It should be purchased through the internet along with the activation process. It looks just as simple as the I-phone. the gray button on the bottom's a track-ball which can be used as a mouse not only by touching the screen Nexus one also could be used by rolling the ball. Free stamp's on the pho
Our interest in the design of machines for human use runs the full gamut of
machine complexity – from the design of single instruments to the design of
complete systems of machines which must be operated with some degree of coordination. - A. Chapanis, W. Garner, & C. Morgan, 1949
