Extra demand
Faced with uncertain supplies of lithium and significant new automotive demand, lithium researcher William Tahil highlights that depletion rates of lithium would exceed current oil depletion rates, switching dependency from one dwindling resource to another. With this in mind, having both electronics and vehicles relying on lithium seems unwise – especially considering that in 2010 around 6 million cameras and over 2 million (albeit predominantly fossil fuelled) cars were sold in the UK alone.
Since batteries used in electric cars require so much more lithium, Tahil recommends that technologies which use unconstrained resources are developed for automotive applications. However, more sustainable technologies could also be used in cameras too.
With so many issues afflicting lithium, ranging from pure scarcity to political agendas and increasing demand, lithium batteries don appear the most sustainable option for cameras. However, the scale of the issue will only really become apparent should electric cars take off in earnest …

This lack of cooperation could result in battery shortages or consumers being held ransom to suppliers price hikes. Then there the issue of lithium reserves simply running dry. “You may find more, you may find a substitute, but we haven yet”, states PwC sustainability chief, Malcolm Preston speaking on Radio 4 in early December.

This might sound like a positive shift from fossil fuels, but lithium has just been named one of the earth most scarce elements in a PwC (PricewaterhouseCoopers) report. Consequently uptake of lithium-intensive electric cars could have a huge impact on lithium powered electronics, including nearly all cameras.
Lithium: You may not know what it looks like or where it comes from but it powers your camera, your phone, your laptop … and if the government gets its way, it will soon be powering your car too.
Socialist Bolivian President Evo Morales has previously made moves to nationalise Bolivia lithium ( which accounts for 50% of the world reserves) and has taken a distinctly anti-capitalist stance. Likewise, China has introduced trade barriers to protect many of its natural resources.

A global wholesale shift to electric cars could exhaust the earth lithium reserves in as little as 50 years, even disregarding non-battery like such as sony NP-F550 battery, sony NP-FR1 battery, sony NP-FM50 battery, sony NP-FM51 battery, sony NP-F10 battery, sony NP-FE1 battery, sony DSC-T7 battery

Panasonic CGA-S101A Battery, Olympus Li-10B Battery, Olympus BLM1 Battery, panasonic NV-GS10 battery, panasonic VHS- C Battery, canon EOS 400D Battery lithium consumption, which currently accounts for three quarters of lithium consumed.
Tahil adds that if portable electronics demand continues at its current growth rate, “Intense competition will arise between the automotive industry and the electronics industry for supply of lithium batteries. Planned and possible production increases will not be able to meet demand from both sectors. “

Alternative options include nickel-metal hydride , zinc and alkaline batteries. These technologies may not currently be as appealing as lithium batteries, but they are potentially more sustainable. Zinc for instance is around 20 times more prevalent than lithium.

The main issue is that a typical electric car consumes 4,000 times more lithium than an AA battery and 800 times more than a large laptop. So what does this mean for photographers? Well, this extra demand for lithium not only poses the threat of spiralling battery prices but puts photographers at the mercy of lithium rich countries. That l be Bolivia, Argentina, Chile and China then.
