Lithium Iron Phosphate Battery
(LFP)
· range of only 500km
└ lower energy density
· battery capacity at -20℃ is only 31.5%
└ Not resistant to low temperatures
· comparatively expensive
└ Lithium is scarce
Metal-Air Batteries
└ High theortical capacity
Li-Air Batteries
└ expensive ×
Al/Mg-Air Batteries
└ cannot charge ×
Zn-Air Batteries
└ cheap and efficient √
Ordinary zinc-air batteries
└ can stand -20℃
Modified Zinc Air Battery
└ can stand -120℃,best perform at -40℃
more than 20% of the current population will experience living temperatures below -20°C。
Battery that works at -20°C could benefit 99.6% of humanity
