In 2010 the United States Advanced Battery Consortium (USABC) dispensed $5.43 million in contractual funding towards advanced battery technology for EVs, hybrids and energy storage. Five companies received finance including Quallion LLC who obtained $1.41 million for an 18 month venture to demonstrate their Matrix battery technology.In addition, giants such as Dow Chemical Company are funding their own ambitious lithium-ion traction battery materials programs.
Californian based Quallion say the Matrix technology "holds great promise for manufacturers seeking to reduce reliability issues and long-term costs." Due to its configuration of combined series and parallel cells the unit can maintain performance even if an individual cell becomes damaged, unlike a conventional structure where it would cause significant disruption. This construction allows the battery to be easily scaled up and reshaped, permitting versatility and reuse.
The patented technology is reliable, durable and low-cost. By using a mass of small cells the overall temperature of the unit is reduced quicker as heat is dispersed at a greater rate. Due to the modular quality of the system, an existing unit can be adapted to meet new conditions preventing the need to create an entirely new one.
For EV manufacturers this could save a considerable amount of time and money as vehicle specifications are altered. Optimisation of EV performance is a key consideration and the Matrix will allow for batteries to be created that suit the dynamics of the vehicle.
The Matrix can be applied in other sectors such as medicine and the military where the company has already deployed the technology.
Envia Systems, ActaCell, Leyden Energy and K2 Energy Solutions have all benefitted from financial assistance provided by the USABC which consists of the Chrysler Group, Ford Motor and General Motors.
The firms were contracted $3.65 million for high-power lithium-ion cells, $179,015 for high-energy cathode materials, $117,733 for lithium-ion technology and $73,644 for modular batteries and large laminated cells, respectively.
"These programs are essential to advance the technology needed to meet both near and long-term goals that will enable a broad spectrum of vehicle electrification", said the USABC's executive director Steve Zimmer.
The funds were provided by the U.S. Department of Energy, which is expending a vast amount of money in efficient vehicle research and development.
