BATTERIES WITH TWICE THE LIFE AND HALF THE CHARGING TIME – TOYOTA FILES PATENTS
Current Lithium Ion batteries cannot be packed too tightly because of fire hazards. This is one of the reasons why electric cars have limited range. Advances in battery technology are producing much more powerful versions of the battery. The challenge is to manufacture them at reasonable cost. Toyota is backing solid state batteries which are likely to provide the best fit for automobiles. These batteries can store nearly twice the energy compared to a liquid electrolyte.
The solid state batteries will also carry less risk of flammability. Also, the new solid state batteries will not be affected by ambient weather. During winter, electric vehicles in Chicago had their range cut by 25%. Considering the 32% of the petroleum is used by automobiles, the changeover to electric vehicles will further cut down demand for petroleum.
