A conference on the research of Lithium-ion battery was held in the AT&T center at UT Austin campus. Detailed information can be found through following link.

The world lithium-ion reasearch leaders, including Jonh Goodenough, Rachid Yamazi., et al, gave their wonderful review and projection of the battery technology. The conference covers wide range of battery topics, giving a whole view of the technological evolution of the lithium-ion battery.

However, it is useful to note some other rising areas of energy storage methodologies. Ultra-capacitor is one of the energy storage strategies, which support very large power density with moderate or small energy density. Current trend is that reduced graphene oxide (chemically modified or activated graphene oxide) is increasing considered as a good choice to improve both the frequency response and the energy density of ultra-capacitors.

You can’t miss the other kind of energy storage approach based on the extremely high breakdown voltage and the high dielectric constant matarials (one of the example is the doped barium-calcium-zirconium-titanate (CMBT)). EEStor is the start-up company working on this area, which was already funded by 3 million USD by Kleiner Perkins Caufield & Byers in 2005. The technology of EEStor is questioned by some experts on the skepticism of current leakage etc. Howerver,  KPCB is one of the most successful venture capital firm in the world. From the understading of the reputation of the KPCB and tehcnology by EEStor, I personally think the idea of EEStor is wonderful and fudamentally it is the sensible way to solve the energy storage problem for both high power density and high energy density. We will see what is coming out in the next a few years and be patient.
