HSINCHU, Taiwan, Dec. 22, 2017 /PRNewswire/ -- ProLogium Technology's Solid State Lithium Ceramic BiPolar+ Cell is selected as a CES 2018 Innovation Awards HONOREE in the Smart Energy product category. This is second times ProLogium won this Innovation Awards since 2017.
Unlike the traditional outside series procedure of conventional Lithium polymer batteries, ProLogium "BiPolar+ Cell" can offer higher voltage in a single cell with a directly inner-series stacking technology. It could enlarge a cell internal nominal voltage from 7.4V to maximum 60V.
Actually, bipolar is not a new concept in Lithium battery field since energy density and cost issue has become a hurdle for many years. There are thousands bipolar-related patents in the world issued by worldwide cell makers, includes first tier cell makers which had decades of company history. However, none of them could manufacture bipolar cell but ProLogium, which is a ten years old company. Two critical reasons that bipolar cell is almost impossible to do so is because (a) conventional battery adopts liquid or jelly electrolyte and fire or explosion will occur by short circuit while series all electrodes in single cell; (b)liquid or jelly electrolyte will be decomposition at more than 5 Volts and fire or thermal runaway occurs easily.
However, ProLogium "BiPolar+ Cell" is solid state battery, no flammable electrolyte inside and still stable over 5 Volts. There is no leakage, no fire, and no explosion even when the cell is folded, cut, or penetrated. The max. temperature of cell during fast charging is even lower than body temp. Overall, solid state electrolyte is the only solution to do bipolar cell and ProLogium's "BiPolar+ cell" is the only one can provide inner series and inner parallel in one single cell at the same time.
Once a cell nominal voltage increase with "BiPolar+ Cell", (1) the energy density of both cell and whole battery pack system will increase; (2) the complex design of BMS, shunt, and protection circuit can be simplified since "BiPolar+ cell" already series (or/and parallel) inside; (3) the quantities of battery cell can be reduced; (4) the metal mechanism, connectors, and wire can be decreased; (5) and final additional benefit is the material cost of battery pack system can by much lower.
Take latest Tesla Model 3 (Panasonic 21700 cylindrical battery cell) of 65.7KWh for instance, if we compare the specific energy density of cell and pack, ProLogium "BiPolar+ cell" at 2018 is less than 21700 in cell level but bigger than 21700 after pack because of its safety and module efficiency.
In 2020, ProLogium "BiPolar+ cell" can even reach 380Wh/kg and 340Wh/kg after pack, which is 27% higher power in cell level and 71% more in pack level. In other words, at the same 65.7KWh, the range of miles with "BiPolar+ cell" can be 376miles (605km) instead of original 200miles (354km).
If we compare the energy density by volume instead of weight, then the devotion of "BiPolar+ cell" is even more obviously. It's original cell energy density in 2018 is 13% less but dramatically increase to 91% more than Model 3 after pack. In 2020, "BiPolar+ cell" can even add additional 147% than Tesla Model 3 in pack level. Put it in another way, the battery pack size of "BiPolar+ cell" at the same 65.7KWh EV is only less than half of Model 3.
Except BEV, "BiPolar+ Cell" is especially suitable for all related big voltage application such as e-bus, e-truck, e-train, UGV, UAV, and ESS…,etc. "BiPolar+ Cell" is an all-in-one and most efficient solution to solve energy issue, safety issue, and cost issue at the same time.
ProLogium (PLG) Solid State Lithium Ceramic "BiPolar+ Cell" will be exhibited at 2018 CES (runs January 9-12 in Las Vegas, NV), Sands Expo Level 2, booth number 44363.
Welcome to witness the glory moment with ProLogium, CES 2018 Innovation Awards HONOREE.
