The sensor, presented at last month’s international conference on lead-acid batteries (LABAT17) in Sofia, Bulgaria, comprises an array of several electrochemical mini-cell sensors that simultaneously and continuously measure electrolyte density in different parts of battery cells.
Chinese battery maker Narada Power Source has boosted the performance of an advanced lead-acid battery by reducing the electrolyte and enhancing the partial state-of-charge window.
The company also tweaked the re-charge algorithms to allow its advanced deep-cycling valve regulated lead-acid (VRLA) battery to achieve more than 26,000 power-assisted cycles.
San Diego company Wildcat Discovery Technologies claims to have discovered a set of electrolyte additives which will boost lithium-ion battery performance.
The U.S. firm claims its SuperFilm™ technology will enable a more uniform and stable solid electrolyte interphase (SEI) on cathodes and anodes.
Alevo, a hitherto virtually unknown Swiss firm, cut the ribbon on a 4m sq ft lithium-ion battery cell/module manufacturing plant in Concord, North Carolina on 28 October.
Hyped in mainstream media as a “revolutionary” lithium-ion battery, Alevo’s cells are based on standard lithium iron phosphate (LiFePO4), albeit with an inorganic gel electrolyte containing sulphur dioxide and a conductive fluorosulphinate salt that is thermally stable, non-volatile and flame resistant.
Austria-based battery research firm Varta Micro Innovation (Varta) has researched anode materials for lithium-ion batteries using a customised rolling-ball viscometer.
Varta researched the qualification and optimisation of new electrolytes such as silicon and discovered that the mobility of lithium-ions is greatly dependent on the viscosity of the electrolyte and that viscosity should be a key focus in technology research.
Daikin Industries has received a US$0.9m grant from the US Department of Energy (DOE) to develop a lithium-ion electrolyte based on fluorochemistries.
China Racing has announced it will be taking part in the Formula E Championship electric vehicle race series in 2014. China Racing is the second of ten teams to be confirmed for the zero-emission race after UK-based Drayson Racing Technologies.
The teams will race on street circuits in ten cities across the world in electric cars. The cars for the inaugural year are being designed by McClaren, Spark Racing Technology and Dallara. All teams have the opportunity to use the customer car for the first year and encouraged to build their own cars for races in the following years. With support from Chinese automotive makers China Racing hopes to build a team car within three years.

Alejandro Agag, Chief Executive Officer of Formula E Holdings said: “China has enormous potential for the expansion of electric vehicles as a tool to fight pollution in cities. We think the FIA Formula E Championship can be a powerful tool to make electric cars popular with the Chinese public, particularly the younger generations. Having a Chinese team with us in the Championship will be key to succeeding in that challenge.”
