Last year, the same team led by USC Viterbi electrical engineering professor Chongwu Zhou developed a successful
anode design using porous silicon nanowires that allowed the material to expand and contract without breaking, effectively solving the pulverization problem.

Using an antimony - based nanocomposite
anode, Manthiram said he could
design a safer, more durable battery that tolerates higher voltages.
The battery that Natron Energy supplied for the study features an unconventional
design for an
anode, which is one of its two electrodes.
Compared with the relatively mature
designs of
anodes used in lithium - ion batteries,
anodes for sodium - ion batteries remain an active focus of R&D.
To solve this problem and make the leap from three volts to four, the first author, University of Maryland assistant research scientist Chongyin Yang,
designed a new gel polymer electrolyte coating that can be applied to the graphite or lithium
anode.
The findings from this study, done through DOE's Joint Center for Energy Storage Research (JCESR), could help scientists
design a safe and stable metallic lithium
anode and ultimately pave the way for the practical use of high - energy - density battery systems for electric vehicles and storing renewable energy.
For the second set the battery
design itself allowed more room for the jelly roll, but a thinner separator still led to poorer protection and reduced tolerance to manufacturing defects as seen with batteries from company A. Without the apparent flaw in the corners, the combination of missing insulation tape, sharp edged protrusions and a thin separator led to a higher probability of short circuit between the cathode tab and the
anode, which resulted in the heating and fire.
